(3) The applicant is a not‐for‐profit 501(c)12 rural electric cooperative, licensee for the water power
project, designated as Project No. 2743 in the records of the Federal Energy Regulatory
Commission, issued on the 5th day of October, 1981.
(4) The amendment of license proposed and the reason(s) why the proposed charges are necessary,
are:
To enable the construction and operation of a new diversion in a location where there is no existing
dam or diversion. The Upper Hidden Basin Diversion (UHBD) would supplement the available
water supply for the existing Project by capturing additional snow melt and rain in the upper
reaches of the Hidden Basin watershed and conveying it westward through a mountain ridge to the
existing Terror Lake reservoir. Once the additional water resource from the UHBD flows into the
Terror Lake reservoir, hydropower would be generated from the existing Project powerhouse and
fed directly into KEA’s existing grid without any operational changes or any other capacity‐related
modifications. This new diversion would enhance the existing Project and allow KEA to provide a
continuous supply of renewable energy to the communities of Kodiak as electrical demand
continues to grow.

Exhibit A – Description of Project
Exhibit A is presented herein that addresses the FERC regulation 18 CFR 4.51 (b).
(b) Exhibit A is a description of the Project.
Kodiak Electric Association, Inc. (KEA or Licensee) received an Order Issuing Major License and
Approving Joint Offer of Settlement (Order Issuing License) for the Terror Lake Project, FERC Project No.
2743 (Project) issued by the Federal Energy Regulatory Commission (FERC or Commission) on October 5,
1981 with an effective date of November 1, 1981. License amendments were issued in 2004, 2008, and
2012 for tailrace remediation, Terror River instream flow averaging, and installation of a third turbine‐
generator unit, respectively.
The Project is a trans‐basin diversion development, capturing water from the Terror River Basin drainage
and the Kizhuyak River Basin and transporting it by means of an un‐pressurized tunnel to a powerhouse
located in the Kizhuyak River Basin. The existing principal features of the Project include: a 193 foot high
rockfill dam with an asphaltic concrete face constructed across the natural outlet of the existing Terror
Lake; a reservoir with a surface area of 1,020 acres at the normal maximum water surface elevation of
1,420 feet and 108,000 acre‐feet of usable storage between elevation 1,250 and 1,420 feet and 136,794
acre‐feet of gross storage capacity; five mile long power tunnel; three additional diversion structures on
tributaries of the Kizhuyak River which provide additional flows; a 3,400 foot long steel penstock; a
powerhouse at elevation 115 feet containing three 11.25 MW generating units, and a valve house at the
dam containing a 10 kW generating unit; a 2,200 foot long tailrace channel conveying flows from the
powerhouse to the main stem of the Kizhuyak River; a 13.8/138 kV switchyard; a 17.3 mile, 138 kV
transmission line from the powerhouse switchyard to a substation located on US Coast Guard property
near the City of Kodiak; and appurtenant facilities.
(1) The physical composition, dimensions, and general configuration of any dams, spillways, penstocks,
powerhouses, tailraces, or other structures, whether existing or proposed, to be included as part of the
project;
Proposed Modifications
KEA proposes to construct two new concrete face rockfill dams approximately 30 feet high and 250
feet wide within an eastern and western tributary branch of the West Fork of Hidden Basin Creek,
approximately six miles upstream of Hidden Basin Lagoon and Ugak Bay on the eastern side of Kodiak
Island, Alaska. Surface water from the diversion dam on the eastern tributary (D‐East) would flow
through a half‐mile long, five foot diameter underground pipe to the diversion dam on the western
tributary (D‐West). From there, surface water from both diversion dams would flow by gravity
through a 1.2 mile long, 12 foot diameter tunnel through a mountain ridge to Terror Lake, the main
reservoir for the Project. The proposed diversion dams would include broad crested weir sections
that would provide adequate spillway capacity during periods of heavy rain and snow melt in excess
of the diversion’s conveyance pipe and tunnel hydraulic capacity. Water flow in excess of the UHBD
conveyance pipe and tunnel capacity would be spilled downstream over the diversion dam spillways
into the West Fork of Hidden Basin Creek. The proposed UHBD would also include a four mile long
spur road off of an existing road to provide access for constructing and maintaining the new diversion.

Terror Lake Hydroelectric Project, FERC Project No. 2743 June 2015
(2) The normal maximum surface area and normal maximum surface elevation (mean sea level), gross
storage capacity, and usable storage capacity of any impoundments to be included as part of the project;
No Changes to Impoundment
The proposed UHBD is a passive water conveyance design with minimal storage capacity behind two
minor diversion dam structures. The proposed UHBD involves no change to the Terror Lake reservoir,
dam or spillway design. The proposed UHBD would supply additional water resources to the Terror
Lake reservoir, but the normal maximum surface area (1,020 acres), normal maximum surface
elevation (1,420 EL), and usable storage capacity (108,000 acre‐feet) remain unchanged.
(3) The number, type, and rated capacity of any turbines or generators, whether existing or proposed, to
be included as part of the project;
No Changes to Powerhouse
There would be no changes to the existing powerhouse, turbines or generators.
(4) The number, length, voltage, and interconnections of any primary transmission lines, whether existing
or proposed, to be included as part of the project (see 16 U.S.C. 796(11));
No Changes to Transmission Lines
There would be no changes to the existing 138 kV transmission line.
(5) The specifications of any additional mechanical, electrical, and transmission equipment appurtenant
to the project; and
No Changes to Appurtenant Project Equipment
There would be no changes to the mechanical, electrical, and transmission equipment appurtenant to
the project.
(6) All lands of the United States that are enclosed within the project boundary described under
paragraph (h) of this section (Exhibit G), identified and tabulated by legal subdivisions of a public land
survey of the affected area or, in the absence of a public land survey, by the best available legal
description. The tabulation must show the total acreage of the lands of the United States within the
project boundary.
The proposed UHBD will require an expansion to the existing Project Boundary as shown in Exhibit G.
Proposed Change to Project Boundary
Current Project Use of Federal Lands Proposed Project Use of Federal Lands
Exclusive of Transmission Lines 4,146 acres Exclusive of Transmission Lines 4,148 acres
Transmission Lines 136 acres Transmission Lines 136 acres
Total Lands of the United States 4,282 acres Total Lands of the United States 4,284 acres
The Project’s licensed boundary currently occupies 4,282 acres of federal lands. Of that total amount,
4,146 acres of the Project boundary is for the Terror Lake reservoir and western portions of the Project
access road and tunnel on federal land administered by the Kodiak National Wildlife Refuge. The
FERC License Amendment Application ‐ Upper Hidden Basin Diversion Exhibit A – Page 3

Terror Lake Hydroelectric Project, FERC Project No. 2743 June 2015
remaining 136 acres is for the transmission line corridor on federal land administered by the US Coast
Guard and Bureau of Land Management.
Most of the UHBD would be constructed on lands owned by the State of Alaska. By necessity of
connecting the water to the existing Terror Lake reservoir, some of the new UHBD would need to be
constructed on federal land already occupied by the Project and administered by the Kodiak National
Wildlife Refuge. A portion of the proposed UHBD tunnel corridor would need to occupy 1.9 additional
acres of federal land administered by the Kodiak National Wildlife Refuge outside the current Project
boundary. This 1.9 acre corridor of expanded Project boundary on federal land would be a subterranean
tunnel, completely underneath a mountain ridge.

Exhibit B – Project Operation and Resource Utilization
Exhibit B is presented herein and addresses the FERC regulation 18 CFR 4.51 (c).
(1) A statement whether operation of the powerplant will be manual or automatic, an estimate of the
annual plant factor, and a statement of how the project will be operated during adverse, mean, and high
water years;
No Changes to Project Operation
There would be no changes to the Terror Lake Hydroelectric Project (Project) powerhouse equipment
or operations with the addition of the Upper Hidden Basin Diversion (UHBD). The Project has
personnel on site continuously and the plant is controlled by the system dispatchers in Kodiak Electric
Association, Inc.’s (KEA’s or Licensee’s) Dispatch Center, located within the City of Kodiak. The Project
will remain to be KEA’s primary source of electric power during adverse, mean and high water years.
The total plant capacity will remain to be 33,750 kilowatts (kW). A 100% plant capacity factor equates
to 296 million kilowatt‐hours (kWh). The Project currently generates 135 million KWh annually. The
new UHBD would add 30,000 acre‐feet of new water resources to the Project annually, equating to 33
million kWh of new energy production made available to the Project. Therefore, the UHBD boosts the
annual plant capacity factor by making more hydropower resources available to the unchanged
Project powerhouse.
Current Plant Capacity Factor Proposed Plant Capacity Factor
46 % 56 %
(2) An estimate of the dependable capacity and average energy production in kilowatt‐hours, supported
by the following data:
No Change to Project Capacity
There would be no changes to the existing powerhouse, turbines or generators. The total generating
capacity of the Project remains unchanged at 33.75 megawatts (MW).
Proposed Increase to Annual Energy Production
The Project’s average generating efficiency is 1,100 kWh per acre‐foot of water. This generating
efficiency rate will remain unchanged because there would be no changes to the existing
powerhouse, turbines and generators. The Terror Lake reservoir, Shotgun Creek Diversion, Falls
Creek Diversion, and Rolling Rock Creek Diversion (all to remain unchanged) currently provide on
average 123,000 acre‐feet of water resources annually to the Project for 135 million kWh of energy
production annually. The proposed UHBD would provide an additional 30,000 acre‐feet of water to
the Project each year; therefore providing an additional energy resource equivalent to 33,000,000
kWh of annual energy production.
Current Annual Production Proposed Annual Production

(ii) An area‐capacity curve showing the gross storage capacity and usable storage capacity of the
impoundment, with a rule curve showing the proposed operation of the impoundment and how the usable
storage capacity is to be utilized;
No Change to Terror Lake Reservoir
There would be no changes to Terror Lake, the main reservoir for the Project. With the Terror Lake
dam and spillway unchanged, the Project’s gross storage capacity and usable storage capacity provided
by the Terror Lake reservoir remains unchanged. Terror Lake’s minimum lake level elevation is 1,250
feet. Maximum lake level elevation is 1,420 feet, which is the elevation of the Terror Lake dam spillway.
The current volume of the Terror Lake reservoir is adequate to utilize the additional inflows provided
by the proposed UHBD under future projections of electrical load demand.
The Project has no license‐mandated lake level elevation rule curve. The Project’s lake levels would
continue to be managed to ensure compliance with its Terror River instream flow requirements as per
FERC License Article 43.

Figure B‐4. Storage versus Elevation of the Terror Lake Reservoir
Terror Lake’s future lake level elevation is expected to be drawn down lower than current lake levels due
to growing load demand and the need for the Project to provide usable storage capacity for the UHBD
inflow, which is primarily supplied during the summer months. This future change in the variability of
Terror Lake’s annual lake level drawdown and/or recharge rates has no impact to any of the Project’s
license‐mandated compliance obligations.

Based upon Terror Lake current area‐capacity curve (Figure B‐4), historical and projected inflows to
Terror Lake (Figure B‐3), and KEA’s future projected load growth (Figure B‐7), the Terror Lake reservoir is
expected to provide ample storage capacity for utilizing the additional inflows provided by the new
UHBD.
During the very wet years, there is always the potential for lake spill if the Project’s available water
supply outpaces KEA’s hydropower production demand. In those wet year situations, the Terror Lake
spillway has ample spillway capacity to pass excess water resource as needed, including the additional
inflows provided by the proposed UHBD. On average, the total future inflows to Terror Lake with the
new inflows contributed by the proposed UHBD are expected to be fully utilized by 2025. Kodiak’s
electric load demand is growing, additional hydropower production is needed, and the Terror Lake
reservoir provides usable storage capacity.

(3) A statement, with load curves and tabular data, if necessary, of the manner in which the power
generated at the project is to be utilized, including the amount of power to be used on‐site, if any, the
amount of power to be sold, and the identity of any proposed purchasers; and
With the exception of station service and transmission losses, all Project power is sold to KEA’s
Cooperative members.
KEA’s Pillar Mountain Wind Project provides on average 26 million kWh of wind energy production
annually. Current conditions of the Project provide on average 135 million kWh of hydropower production
annually. That brings KEA’s current renewable hydro‐wind power production portfolio to a total of 161
million kWh annually. By 2020, KEA’s load growth demand is expected to exceed 179 million kWh,
requiring additional power beyond KEA’s current hydro‐wind power production levels. The proposed
UHBD would provide additional water resources to the Project so that an additional 33 million kWh of
annual hydropower production may be added to KEA’s grid. The full contribution of the UHBD is expected
to be fully utilized by 2025.

Exhibit D – Statement of Costs and Financing
Exhibit D is presented herein and addresses the FERC regulation 18 CFR 4.51 (e).
(e) Exhibit D is a statement of costs and financing.
(1) N/A ‐ This is not an application for an initial license.
(2) N/A ‐ This is not an application for a new license.
(3) If the application includes proposals for any new development, a statement of estimated costs,
including:
(i) The cost of any land or water rights necessary to the new development
Most of the Upper Hidden Basin Diversion (UHBD) would be constructed on lands owned by the State of
Alaska, administered by the Department of Natural Resources (DNR). The purchase of land is not
necessary for the new development. Kodiak Electric Association, Inc. (KEA or Licensee) initiated the
application process with DNR in April, 2015 for securing land use and water use rights necessary to
construct and operate the UHBD. As per the guidance of DNR staff, the exact cost of the land and water
rights associated with the proposed UHBD is not determined until after the UHBD is built and
operational. Therefore, the cost of land and water rights necessary to the new development are not
known at this time.
(ii) The cost of the new development, with specification of:
(A) Total cost of each major item;
(B) Indirect construction costs such as cost of construction equipment, camps and commissaries;
(C) Interest during construction;
(D) Overhead, construction, legal expenses, taxes, administrative and general expenses, and
contingencies.
The total cost to develop the UHBD is estimated at $79,992,000, as itemized in the table below.

the Terror Lake Hydroelectric Project (Project) site. Building materials and associated equipment
needed to construct the UHBD would be transported to the Project’s existing jetty dock, transported on
the Project’s existing access road, and stored in the Project’s existing warehouse. The electric energy
derived from the additional water resources supplied by the UHBD to the Terror Lake reservoir will be
generated by the Project’s existing infrastructure. Operating the UHBD incurs no additional cost to the
current Project facilities (i.e., powerhouse, turbines, generators, switchyard, and transmission line).
(4) A statement of the estimated average annual cost of the total project as proposed specifying any
projected changes in the costs (life‐cycle costs) over the estimated financing or licensing period if the
applicant takes such changes into account, including:
(i) Cost of capital (equity and debt);
The most recently received interest rate quote from KEA’s financing institutions was at 3.87%. If
financing is provided by CoBank ACB, a member‐owned cooperative financing institution that returns
capital credits (dividends) on its loans, then the capital credits would provide approximately a 1%
interest rate reduction in the form of cash and credit back. These capital credits are not factored into
the NPV or UHBD savings at this time.
(ii) Local, state and Federal taxes;
KEA is the sole owner of the Project, and is a generation, transmission and distribution not‐for‐profit
rural electric cooperative. As a 501(c)12 not‐for‐profit organization, KEA is exempt from local, state, and
federal taxes.
(iii) Depreciation and amortization;
The industry average annual depreciation rate applied to hydroelectric facilities, and the RUS standard
under which KEA is governed, is 2%. This equates to a 50‐year facility life. When the total construction
cost estimate ($79,992,000) is divided by a 50‐year term, the annual depreciation expense of the UHBD
comes to $1,599,840.
Based upon KEA’s experience with its financing institutions, it is highly probable that the amortization of
the UHBD loan would be set at 30 years. At a 3.87% interest rate, this provides for an annual interest
and principal payment of $4,518,764. If financing is provided by CoBank ACB, a member‐owned
cooperative financing institution that returns capital credits (dividends) on its loans, then the capital
credits would provide approximately a 1% interest rate reduction in the form of cash and credit back.
These capital credits are not factored into the NPV or UHBD savings at this time.
(iv) Operation and maintenance expenses, including interim replacements, insurance, administrative and
general expenses, and contingencies; and
The UHBD components would be a basic, non‐mechanical design intended for un‐manned water
conveyance. KEA has been operating and maintaining three other similar diversions at the Project for 30
years. The cost to maintain these types of diversion structures is low. No additional personnel would be
necessary to operate or maintain the UHBD. Annual maintenance activities for the UHBD would consist
of an annual or biennial clearing of accumulated rock or silt debris behind the two diversion dams, which
is estimated to cost $150,000 in 2020. KEA’s UHBD budget assumes a maintenance cost inflation rate of
3%.

Terror Lake Hydroelectric Project, FERC Project No. 2743 June 2015
(v) The estimated capital cost and estimated annual operation and maintenance expense of each
proposed environmental measure.
No proposed environmental measure costs are included in this proposal.
(5) Statement of the estimated annual value of project power based on the estimated average annual
cost of obtaining an equivalent amount of power (capacity and energy) from the lowest cost alternative
source, specifying any projected change in the cost of power from that source over the estimated
financing or licensing period if the applicant takes such changes into account.
If the UHBD were not built, the only other alternative source of viable power available to meet KEA’s
growing load demand is diesel fuel. KEA is already pushing the technologic edge for wind penetration
with battery and flywheel energy storage system integration, and cannot add any more wind generation
to its grid. The only other alternative for obtaining an equivalent amount of power is diesel‐based
generation. KEA’s diesel‐generation efficiency is 14.2 kilowatt‐hours per gallon of diesel fuel. KEA’s
historical average cost of diesel fuel is $3.14 per gallon. In addition to the direct cost of diesel fuel,
diesel engine maintenance costs average 4¢ per kWh. KEA’s UHBD Budget assumes a fuel and
maintenance cost inflation rate of 3%.
KEA proposes to have the UHBD operational by 2020. KEA’s system load demand in 2020 is expected to
be 18 million kilowatt‐hours (kWh) greater than KEA’s currently available hydropower and wind energy
supply. Therefore, without the additional water resources provided by the UHBD, the 18 million kWhs
of additional load demand would require diesel‐generated power. Based on the diesel generation
efficiency rates and 3% inflation rates on fuel and maintenance costs, the direct fuel costs for generating
that amount of electricity without the UHBD is approximately $4.5 million, plus $818,825 in diesel
engine maintenance cost. (See table below.)
Because the only other feasible alternative to power generation on Kodiak Island is diesel, the value of
the UHBD is exceptionally high. Even with the expenses of constructing this new diversion, including
debt and maintenance costs, the first year benefits of the UHBD would be net positive at $676,666 in
savings.
Year 1 Costs Year 1 Savings
Debt cost $4,518,764 Savings from avoided fuel cost $4,526,605
Maintenance cost $150,000 Savings from avoided engine maintenance $818,825
Total Cost in Year 1 $4,668,764 Total Savings in Year 1 $5,345,430
NET SAVINGS in Year 1 = $676,666
The cost‐saving benefits of hydropower continue to escalate to $5.7 million in Year 5 of UHBD
operation. Over the 30‐year financing term, a total of 66,947,372 gallons of diesel fuel are expected to
be saved from the additional hydropower production made possible by the water resources of the
UHBD. The direct savings from the avoided fuel cost is $380 million, plus the additional $69 million in
savings from avoided diesel engine maintenance cost.
Compared to the diesel alternative, the net present value (NPV) at a 5% discount rate for the UHBD is
over $129 million. That is a significant savings for the Kodiak community.
FERC License Amendment Application ‐ Upper Hidden Basin Diversion Exhibit D – Page 4
Kodiak Electric Association, Inc. Pre‐Application Document
Terror Lake Hydroelectric Project, FERC Project No. 2743 June 2015
Other unquantifiable benefits of this project, such as the stabilized cost of power, energy independence,
reduction in pollution and greenhouse gasses, and the renewable energy marketing opportunities
provided to Kodiak’s business community are not included in this economic analysis; however, it should
be noted that those aspects of the project also increase the value of the UHBD and overall Terror Lake
Hydroelectric Project for the long‐term sustainable health of Kodiak.
(6) A statement specifying the sources and extent of financing and annual revenues available to the
applicant to meet costs identified in paragraphs (e)(3) and (4) of this section.
If KEA does not receive augmented financing or grants from a State or Federal renewable energy
initiative program, then KEA is prepared to take responsibility for the direct financing of the total
construction cost. KEA is a rural electric cooperative with a long history with lending institutions able to
provide KEA with direct financing: CoBank, ACB, National Rural Utilities Cooperative Finance
Corporation (NRUCFC), and US Department of Agriculture’s Rural Utilities Service (RUS).
KEA is held to specific financial standards with its Equity levels, Debt Service Coverage (DSC) and Times
Interest Earnings Ratios (TIER) as a condition of borrowing capacity. KEA is a self‐regulated utility that
has the ability to adjust rates to ensure that revenue will continue to meet cost if necessary; however
the benefits that the UHBD provides to the KEA membership through the reduction in costly diesel‐
powered generation is the justification and purpose of this project. Once the capital expenditure is paid,
the long‐term savings provided by the UHBD are expected to reduce KEA’s overall revenue
requirements.
(7) An estimate of the cost to develop the license application;
The estimated cost to develop the FERC license application is $2,500,000. This cost is included in the
total construction cost estimate of $79,992,000.
(8) The on‐peak and off‐peak values of project power, and the basis for estimating the values, for
projects which are proposed to operate in a mode other than run‐of‐river; and
The concept of on‐peak and off‐peak values of project power are not applicable to this proposal. KEA is
the only electric utility in Kodiak and there would be no power purchase agreements.
The electric energy derived from the additional water resources supplied by the UHBD to the Terror
Lake reservoir will be generated by the Project’s existing infrastructure and would go straight into the
KEA grid. Likewise, the project savings would go straight to the members of the Cooperative. The
community would experience a lower cost of power from decreased diesel fuel consumption. The high
value of the UHBD is described in further detail above.
(9) The estimated average annual increase or decrease in project generation, and the estimated average
annual increase or decrease of the value of project power, due to a change in project operations (i.e.,
minimum bypass flows; limits on reservoir fluctuations).
The proposal would not change the authorized installed capacity of the Project; however, the additional
water resources added to Terror Lake from the UHBD is expected to increase average annual generation
by an additional 33 million kilowatt‐hours.

There would be no change to Project operations. The Project has no license‐mandated lake level
elevation rule curve. The Project’s lake levels would continue to be managed to ensure compliance with
its Terror River instream flow requirements as per FERC License Article 43.

FERC NO. 2743
Submitted to:

Prepared and Submitted by Project Licensee:
Kodiak Electric Association, Inc.
Kodiak, Alaska
June 2015
FERC License Amendment Application ‐ Upper Hidden Basin Diversion PDEA – Page ii
Kodiak Electric Association, Inc. Draft
Terror Lake Hydroelectric Project, FERC Project No. 2743 June 2015
Executive Summary
On October 5, 1981, the Federal Energy Regulatory Commission (FERC or Commission) issued a license
to Kodiak Electric Association, Inc. (KEA) for the Terror Lake Hydroelectric Project, FERC Project No. 2743
(Project). The Project is located in north central Kodiak Island in the Kodiak Island Borough
approximately 25 miles southwest of the City of Kodiak. The license was issued on October 5, 1981, with
an effective date of November 1, 1981. The Project commenced commercial operation in 1985, and it
remains to be the primary source of KEA’s energy supply.
KEA is a rural electric cooperative that provides electricity to approximately 6,000 meters on Kodiak
Island, Alaska in a service area that includes the region in and around the City of Kodiak, Bells Flats,
Chiniak, Pasagshak, Port Lions, and the nation’s largest US Coast Guard Base. The Terror Lake
Hydroelectric Project is the cornerstone to KEA’s award‐winning renewable energy system. On an
annual average, KEA’s electric grid is powered with 80% hydropower from the Terror Lake Hydroelectric
Project and 20% wind energy from the Pillar Mountain Wind Project. For 2014 and 2015 year‐to‐date,
KEA’s electric grid achieved a 99.7% renewable energy portfolio, with a 99.9% reliability factor. KEA’s
success in developing its innovative hydro‐wind electric grid has eliminated diesel fuel as the
community’s primary power supply.
Annual energy production requirements for KEA’s grid in 2014 were 159 million kilowatt‐hours (kWh).
By 2020, KEA’s system‐wide load growth demand is expected to surpass 179 million kWh due to
expansions of Kodiak’s seafood processing sector, the repowering of the City’s shipping port crane,
numerous new building construction projects, and an overall community‐wide shift of energy sourcing
from diesel fuel to renewable electricity. KEA’s isolated grid system is currently able to supply 161
million kWh of renewably generated electricity annually. Without additional sources of renewable
energy to meet the upcoming load demand, KEA will need to revert back to diesel‐based generation.
Returning to a reliance on expensive, barged‐in diesel fuel is not an acceptable option for the future
viability of Kodiak’s economy and environment.
KEA’s vision is to maintain 95% of energy sales with cost effective renewable power solutions for the
future of their Cooperative members and the Kodiak community. Optimizing KEA’s existing hydropower
resources is the solution to achieve this renewable energy vision.
There is a limited amount of water available within the Terror Lake reservoir, and when that available
energy supply is drawn down to low lake levels, more energy is needed to continue powering KEA’s
growing loads. KEA cannot add any more wind generation to the KEA grid, as it is already pushing the
technologic edge for its high levels of wind penetration with a unique energy storage system involving
both battery and flywheel technology. Tidal and wave energy generation technology remains in the
pilot testing phase, and is not yet ready for utility‐scale deployment and operation. Adding more water
to Terror Lake would be the most cost‐effective, and minimally‐invasive approach for adding more
renewable energy onto KEA’s isolated micro‐grid.
The Upper Hidden Basin Diversion (UHBD) is the most feasible energy project available to KEA. This
diversion provides the KEA grid with the energy it needs, and it can be achieved through a straight‐
forward approach that utilizes existing power generation equipment. KEA is ready to move forward
with this next step in our renewable energy vision.
Proposed Action
This Draft Application for Non‐Capacity Amendment to License, including the Preliminary Draft
Environmental Assessment (PDEA) (Draft Amendment Application) provides information in support of
FERC License Amendment Application ‐ Upper Hidden Basin Diversion PDEA – Page iii
Kodiak Electric Association, Inc. Draft
Terror Lake Hydroelectric Project, FERC Project No. 2743 June 2015
KEA’s proposed construction of the UHBD. This new diversion would supplement the Project’s available
water supply by capturing additional snow melt and rain in the upper mountain tributaries of the West
Fork of Hidden Basin Creek and conveying it westward through a mountain ridge to the existing Terror
Lake reservoir. The diversion components would be a basic, non‐mechanical design intended for un‐
manned water conveyance. Once the additional water resources from the UHBD flow into the Terror
Lake reservoir, hydropower would be generated from the existing Project powerhouse and fed directly
into KEA’s existing grid without any operational changes or any other capacity‐related modifications.
The proposed UHBD would be located above 1,400 foot elevation in the mountainous uplands of Kodiak
Island, approximately six miles upstream of the Hidden Basin lagoon that flows into Ugak Bay on the
eastern side of Kodiak Island, Alaska. The upper catchment area of the Hidden Basin watershed is
estimated to convey 30,000 acre‐feet of snow melt and rain. The UHBD would add this 30,000 acre‐feet
of water to the Terror Lake reservoir by constructing two concrete‐face rockfill dams within an eastern
and western tributary branch of the West Fork of Hidden Basin Creek. Surface water from the diversion
dam on the eastern tributary (D‐East) would flow through a half‐mile long, five foot diameter
underground pipe to the diversion dam on the western tributary (D‐West). From there, surface water
from both diversion dams would flow by gravity through a 1.2 mile long, 12 foot diameter tunnel
through a mountain ridge to Terror Lake. Water flow in excess of the UHBD conveyance pipe and tunnel
capacity would be spilled downstream over the diversion dam spillways into the West Fork of Hidden
Basin Creek. The proposed UHBD would also include a four mile long spur road off of an existing road to
provide access for constructing and maintaining the new diversion. The proposal would not change the
authorized installed capacity of the Project; however, the additional water resources added to Terror
Lake from this diversion are expected to increase average annual generation by 33 million kWh.
Alternatives Considered
The UHBD is the most feasible and cost‐effective approach to supplying electric power in Kodiak. KEA’s
load demand is growing because the community is switching its source of energy from fossil fuels to
locally‐ and renewably‐generated electricity. It may seem counter‐intuitive that conservation efforts are
creating higher electric loads, but it is because of KEA’s success in providing its members with affordable
renewable energy that electricity makes better overall sense and savings per British Thermal Unit (BTU)
than fossil fuels.
KEA operates on a remote, completely isolated electric grid unconnected to any other electric system.
There are no local sources of natural gas, coal, or nuclear power on Kodiak Island, nor would it be
feasible to import any of those fuel sources to Kodiak due to transportation logistics, high cost, pollution
controls and safety requirements. KEA is already pushing the technologic edge for variable wind energy
penetration on its isolated micro‐grid with battery and flywheel energy storage system integration, and
cannot practically engineer any more intermittent source energy, such as wind or solar, onto its system.
Tidal and wave energy generation technology remains in the pilot testing phase and is not yet ready for
utility‐scale deployment and operation. Developing an entirely new hydropower facility separate and
redundant to the existing Project is not practical. The only other alternative for obtaining an equivalent
amount of power other than the UHBD would be diesel‐based generation. However, reverting back to a
dependence on barged‐in diesel fuel for local electric generation is not reasonable, due to both
economic and environmental costs. The UHBD is the most viable option for supplying continuous
renewable power to KEA’s remote electrical grid.

The FERC Pre‐Filing Consultation Process and Public Involvement
On March 4, 2015, KEA consulted via teleconference with FERC staff in the Division of Hydropower
Administration and Compliance (DHAC) regarding the applicable FERC regulatory requirements and
discussed KEA’s interest in substituting the PDEA that meets the requirements of the FERC regulations
and the National Environmental Policy Act (NEPA) for the Environmental Exhibit E. KEA received
guidance from FERC staff regarding the process and the application and herein provides a Draft
Application for Non‐Capacity Amendment to License with a PDEA in accordance with the three‐stage
consultation process outlined in FERC regulation 18 CFR 4.38.
KEA initiated field studies of the proposed UHBD site and the downstream Hidden Basin Creek area in
2013. The scope of studies completed to date include surface water stream gauging; watershed
hydrology; fish presence, absence and distribution; preliminary wetland assessment; cultural resources;
conceptual engineering design; and conceptual construction cost estimate. Scope of studies currently in
progress for 2015 include ongoing surface water stream gauging; watershed hydrology; fish presence,
absence and distribution; and surveying and mapping. Surface water gauging of Hidden Basin Creek was
also conducted by the US Geologic Survey (USGS) from 1982 to 1984.
This PDEA is provided to the relevant Federal and State resource agencies, local stakeholders and native
organizations, and filed with FERC 30 days before the Joint Public/Agency meeting on July 21, 2015. The
public review period will be for a period of 60 days after the Joint Public/Agency meeting and comments
are due to FERC by September 21, 2015. After the public review and comment period, comments
received will be incorporated into the final version of this document.

Terror Lake Hydroelectric Project, FERC Project No. 2743 June 2015
1. Introduction
On October 5, 1981, the Federal Energy Regulatory Commission (FERC or Commission) released an
Order Issuing Major License and Approving Joint Offer of Settlement (Original License) for the Terror
Lake Hydroelectric Project – FERC Project No. 2743 (Project) to Kodiak Electric Association, Inc. (KEA)
with an effective date of November 1, 1981. The Project commenced commercial operation in 1985,
and it remains the primary source of KEA’s energy supply.
The Terror Lake Hydroelectric Project is a trans‐basin development, capturing water from the Terror
watershed and Kizhuyak River drainage and transporting it by means of tunnel to a powerhouse located
on the west bank of the Kizhuyak River. (Refer to Figure A‐3, Conceptual Project Layout.) The
powerhouse contains three 11.25 megawatt (MW) turbine‐generator units; each unit comprises a
vertical shaft 6‐jet Pelton turbine and synchronous generator. Two units were authorized in the Original
License issued on October 5, 1981, and the third unit was authorized in a Capacity Amendment to
License issued on February 17, 2012.
This Draft Application for Non‐Capacity Amendment to License, including the Preliminary Draft
Environmental Assessment (PDEA) (Draft Amendment Application) provides information in support of
KEA’s proposed construction of the Upper Hidden Basin Diversion (UHBD) located on the upper
tributaries of the Hidden Basin watershed. KEA proposes to expand the Project with the addition of a
water conveyance diversion that brings water resources from the upper reaches of the Hidden Basin
watershed to the Terror watershed. The UHBD components would be a basic, non‐mechanical design
intended for un‐manned water conveyance.
1.1 Purpose of and Need for Action
1.1.1 Purpose of Action
The Project is the primary source of KEA's energy supply, and is the cornerstone to KEA's renewable
wind‐hydro energy generation system. This Draft PDEA addresses construction of the UHBD. This new
diversion would supplement the Project’s currently available water supply to boost hydropower
production at the existing facility so that KEA’s growing load demand can continue to be powered with
renewable energy. The proposal would not change the authorized installed capacity of the Project;
however, the additional water resources added to Terror Lake from the UHBD are expected to increase
average annual generation of the Project by an additional 33 million kilowatt‐hours (kWh).
Diverting water from the Hidden Basin watershed was considered during the original design and
construction of the Project. The 1978 Terror Lake Hydroelectric Project’s Definite Project Report stated:
“The Hidden Basin Creek diversion works are not included in the recommended development of
the Terror Lake Project at this time [1978]. However, this scheme is the most economical means
of increasing the output of the development above its presently projected level, and it can be
built whenever the growth in power demand in Kodiak justifies it. Therefore, the scheme is
included in the present report as a recommended future development.”
KEA is familiar with the ground conditions and Project operation in this remote area of Kodiak Island.
KEA already operates and maintains three other diversions at the Project as part of the existing
hydropower system. The proposed UHBD area is adjacent to existing Project lands, east of the Terror
Lake reservoir and south of the Shotgun Creek Diversion. The proposed UHBD tunnel would run though
the same stable granitic ridge as the Terror Lake power tunnel. Based on KEA’s familiarity with this
region of Kodiak Island and observations from recent field surveys, KEA does not anticipate any
technological barriers to the development of this project.

Terror Lake Hydroelectric Project, FERC Project No. 2743 June 2015
Adding more water to the existing Project would be the most cost‐effective and minimally‐invasive
approach for adding more renewable energy onto KEA’s isolated grid. The UHBD is the next step
necessary for KEA to achieve its vision statement: “Endeavor to maintain 95% of energy sales with cost
effective renewable power solutions for the future of our members and the community.” Enhancing KEA’s
wind‐hydro system with the additional hydro resource of Upper Hidden Basin makes it possible for KEA
members to displace diesel fuel as an energy and heat source in their homes and businesses, and it
supports Kodiak’s economic growth in the global seafood industry. The energy independence provided
by KEA’s wind‐hydro system is a significant benefit for the remote island community of Kodiak. With the
UHBD, Kodiak can continue to rely on affordable, locally‐generated, clean energy as the foundation for
the community’s quality of life.
1.1.2 Need for Action
KEA provides electricity to approximately 6,000 meters on Kodiak Island, Alaska in a service area that
includes the region in and around the City of Kodiak, Bells Flats, Chiniak, Pasagshak, Port Lions, and the
nation’s largest US Coast Guard Base. KEA's system operates in a remote island environment with no
interconnections to outside sources of power. (Refer to Figure A‐2, KEA Service Area.)
The Terror Lake Hydroelectric Project is the cornerstone to KEA’s renewable wind‐hydro energy system.
On an annual average, KEA’s electric grid is powered with 80% hydropower from the Project, and 20%
wind energy from the Pillar Mountain Wind Project. KEA’s renewable hydro‐wind generation system is
currently able to supply 161 million kWh of electricity annually to its isolated grid. Annual energy
production requirements for KEA’s grid in 2014 were 159 million kWh, and this energy demand was
powered by KEA’s 99.7% renewable energy portfolio. However by 2020, KEA’s system‐wide load growth
demand is expected to exceed 179 million kWh due to expansions of Kodiak’s seafood processing sector,
the repowering of the City’s shipping port crane, numerous new building construction projects, and an
overall community‐wide shift of energy sourcing from diesel fuel to renewably‐generated electricity.
Without additional sources of renewable energy to meet the growing load demand, KEA reverts back to
diesel‐based generation. Returning to a reliance on expensive, barged‐in diesel fuel is not an acceptable
option for the viability of Kodiak’s economic and environmental future.
KEA’s load demand is growing because the community is developing new infrastructure based on
renewable electricity as the local energy solution. It may seem counter‐intuitive that conservation
efforts are creating higher electric loads, but it is because of KEA’s success in providing its members with
affordable renewable energy that electricity makes better overall sense and savings per British Thermal
Unit (BTU) than fossil fuels. KEA does not want to fall into the same dilemma other Alaskan utilities
have faced when growing loads outpace the supply of renewable energy.
There is a limited amount of water available within the Terror River watershed, and when available
energy supply is drawn down to low reservoir levels, more energy is needed to continue powering KEA’s
growing loads. KEA’s grid cannot integrate additional wind energy at this time. Stably integrating 80%
wind penetration rates on an isolated micro‐grid is an unprecedented electrical engineering feat that
KEA achieved by building its innovative electrical infrastructure to balance the variability of high
penetration wind energy with stored energy injections from flywheels, battery arrays, and hydropower.
KEA is already pushing the technologic edge for integrating its current levels of wind energy. The
additional energy needed on KEA’s system will not come from wind. KEA continues to examine the
potential for other forms of renewable resource development such as solar, tidal, run‐of‐the‐river, and
wave energy; however, those forms of energy are also variable and intermittent like wind energy. The
stable integration of these variable forms of energy on KEA’s isolated micro‐grid has reached its
maximum under KEA’s current conditions. Further, tidal and wave energy generation technology

Terror Lake Hydroelectric Project, FERC Project No. 2743 June 2015
remains in the pilot testing phase, and is not yet ready for utility‐scale deployment and operation. There
are no local sources of natural gas, coal, or nuclear power on Kodiak Island. It would not be feasible to
import natural gas, coal, or nuclear fuel to Kodiak due to transportation logistics, high cost, safety
precautions, and pollution control requirements. Developing an entirely new hydropower facility
separate and redundant to the existing Project is not practical. The only other alternative for obtaining
an equivalent amount of power is diesel‐based generation. However, reverting back to a dependence
on barged‐in diesel fuel for local electric generation is not reasonable, due to both economic and
environmental costs.
Enhancing existing hydropower assets with a new diversion that brings more water to the Project is the
most practical, cost‐effective and minimally‐invasive option available for adding renewable energy to
KEA’s electrical grid system. The UHBD is the most viable option for supplying continuous renewable
power to KEA’s remote electrical grid.
1.2 Description of the Application Process
This Draft Amendment Application, including the Draft PDEA, involves KEA’s request to construct and
operate a new diversion in a location where there is no existing dam or diversion as part of the existing
FERC License No. 2743. When a licensee proposes to add a new diversion to an existing project, the
Commission’s regulations and terms of the license require that the licensee file an application for
amendment for Commission approval.
1.2.1 Applicant
KEA is a not‐for‐profit 501(c)12 rural electric cooperative and is not claiming preference under section
7(a) of the Federal Power Act (FPA). KEA owns and operates the existing Project.
1.2.2 Type of Amendment
This Draft Amendment Application is classified as a Non‐Capacity Amendment to License of an existing
Project pursuant to the Commission’s regulations at 18 CFR 4.201(c). The proposed UHBD is a new
diversion in a location where there is no existing dam or diversion, thereby subject to pre‐filing

discuss KEA's proposed Non‐Capacity Amendment. KEA was directed by DHAC staff to use the three‐
stage consultation process as set forth in the regulations at 18 CFR 4.38 consultation requirements.
The First Stage of Consultation commences with KEA's initiation of consultation with appropriate
resource agencies, affected Alaska Natives, and members of the public (Participants) regarding the
proposed Joint Public/Agency Scoping Meetings (Scoping Meetings) to discuss issues and develop the
agenda for these meetings.
KEA herein provides the Pre‐Application Document (PAD) prepared in the format of the Application for
Non‐Capacity Amendment to License and the Draft PDEA. The Draft PDEA provides information
regarding the environmental and economic effects associated with this Draft Amendment Application.
KEA herein initiates consultation with the state and federal resource agencies pursuant to the
Commission’s three stage consultation regulation (18 CFC 4.38), and with other entities interested in
KEA’s proposal prior to the filing of the Final Application for Non‐Capacity Amendment to License (Final
Amendment Application).
The Scoping Meetings will be held July 21, 2015 in Kodiak, Alaska. Participants are provided with a 30‐
day period within which to review KEA’s proposal prior to the Scoping Meetings. The public review and
comment period will continue for 60 days after the Scoping Meeting, concluding on September 21,

2. Proposed Action and Alternatives
Construction and operation of the UHBD is not anticipated to result in significant environmental impact.
The purpose of the proposal is to divert a small portion of water resources from the upper reaches of
the Hidden Basin watershed to the Terror watershed for renewable energy production. The UHBD
would be similar to existing diversion structures currently in operation at the Project. For the past 30
years, KEA has proven that it can successfully and responsibly construct and operate these types of
structures in this environment without adverse effects.
The UHBD comprises only 15% of the overall Hidden Basin watershed size, and is located above two
large waterfalls in a mountainous tundra area where no fish have been observed. No threatened or
endangered species are located within the vicinity of this area. There would be minimal change in the
facility’s aesthetic appearance, and there is no recreational or other public use at the site.
Constructing the new diversion dams and access road will require structures to be placed within
tributary creeks and wetlands; however, this activity is routinely authorized under license and permit
terms and conditions that specify best management practices requirements to minimize potential
impacts to the aquatic and terrestrial environments for this type of activity. The minor impacts incurred
by temporary construction activities are far outweighed by the long‐term benefits associated with
minimizing the pollution associated with fossil fuel consumption achieved by enhancing renewable
energy infrastructure with this hydropower diversion.
KEA initiated field studies of the proposed UHBD and the downstream Hidden Basin Creek area in 2013.
The scope of studies completed to date include surface water stream gauging; watershed hydrology; fish
presence, absence and distribution; preliminary wetland assessment; cultural resources; conceptual
engineering design; and conceptual construction cost estimate. The scope of studies currently in
progress for 2015 include ongoing surface water stream gauging; watershed hydrology; fish presence,
absence and distribution; and surveying and mapping. Historical data are available from surface water
gauging of Hidden Basin Creek conducted by the US Geologic Survey (USGS) from 1982 to 1984.
The following Table 2‐1 provides an overview of the resource issues identified to date and provides
clarifying statements regarding whether a particular resource would be affected. The table also
provides proposed measures that KEA would implement to avoid any adverse environmental effects
during the construction and operation of the UHBD.

2.1 Proposed Action
KEA proposes to expand the Project with an additional diversion (UHBD) to convey water resources from
the upper reaches of the Hidden Basin watershed to the Terror watershed. The UHBD components
would be a basic, non‐mechanical design intended for un‐manned water conveyance.
KEA proposes to construct two new concrete face rockfill dams approximately 30 feet high and 250 feet
wide within an eastern and western tributary branch of the West Fork of Hidden Basin Creek,
approximately six miles upstream of Hidden Basin Lagoon and Ugak Bay on the eastern side of Kodiak
Island, Alaska. Surface water from the diversion dam on the eastern tributary (D‐East) would flow
through a half‐mile long, five foot diameter underground pipe to the diversion dam on the western
tributary (D‐West). From there, surface water from both diversion dams would flow by gravity through
a 1.2 mile long, 12 foot diameter tunnel through a mountain ridge to Terror Lake, the main reservoir for
the existing Project. The proposed diversion dams would include broad crested weir sections that would
provide adequate spillway capacity during periods of heavy rain and snow melt, and any amount water
flow that exceeds the capacity of the UHBD conveyance pipe and tunnel would be spilled into the West
Fork of Hidden Basin Creek. The proposed UHBD would also include a four mile long spur road off of an
existing road to provide access for constructing and maintaining the new diversion. (Refer to Figure A‐4,
Conceptual UHBD Layout.)
FERC License Amendment Application ‐ Upper Hidden Basin Diversion PDEA – Page 13
Kodiak Electric Association, Inc. Draft
Terror Lake Hydroelectric Project, FERC Project No. 2743 June 2015
The proposal would not change the authorized installed capacity of the Project or any other feature of
the existing Project; however, the additional water resources added to Terror Lake from this new
diversion are expected to increase average annual generation by an additional 33 million kWh.
2.1.1 Project Location
Kodiak Island, located in the Gulf of Alaska, is the largest island in Alaska and second largest island in the
United States (US). It is 252 air miles south of Anchorage, Alaska (a 45‐minute flight) and a 4‐hour flight
from Seattle, Washington. Kodiak Island contains the Kodiak National Wildlife Refuge which
encompasses nearly 1.9 million acres of land on Kodiak and Afognak Islands. The largest city on Kodiak
Island is the City of Kodiak (City), located within the Kodiak Recording District and Kodiak Island Borough
(KIB) near the northeastern tip of Kodiak Island. The Terror Lake Hydroelectric Project is located
approximately 25 air miles southwest of the City. (Refer to Figure A‐1, Site Location Map and Figure A‐2,
KEA Service Area.)
This Draft Amendment Application involves a new diversion in the mountainous uplands of the Hidden
Basin watershed, east of the existing Terror Lake reservoir on Kodiak Island at approximately 57˚ 36’ 30”
North, 153˚ 0’ 10” West. The proposed UHBD would be located on upper tributaries of the West Fork of
Hidden Basin Creek, approximately six miles upstream of Hidden Basin Lagoon and Ugak Bay.
Most of the UHBD would occupy land owned by the State of Alaska. The proposed action’s new road
and conveyance structures would add approximately 160 acres to the existing FERC licensed boundary
of the Project. Of this 160 acres, approximately 140 acres would encompass a new access road that
would connect the existing Project access road to the proposed UHBD site for construction, and
subsequent inspection and maintenance. Approximately 15 acres of the proposed Project boundary
expansion would encompass the two diversion dam structures on State land, and the remaining 5 acres
would encompass a subterranean tunnel that would connect the UHBD dams to the Terror watershed.
The tunnel outlet portal on the Terror Lake side of the mountain ridge would be located in an area
already encompassed by the existing FERC licensed Project boundary.
A detailed map of the proposed revisions to the FERC‐licensed Project boundary are provided in Draft
Exhibit G – Project Map.
2.1.2 Use of Existing Facilities
The electric energy derived from the additional water resources supplied by the UHBD to the Terror
Lake reservoir will be generated by the Project’s existing infrastructure. KEA’s current infrastructure is
already able to utilize the water resources provided by the UHBD to generate the additional hydropower
and deliver the renewable electricity to KEA’s service area. The existing infrastructure associated with
the Project will continue to operate in the same manner without design or engineering changes.
Specifically,
There would be no changes to the Terror Lake dam, spillway, intake structure, Terror River
outlet works, power tunnel or penstock;
There would be no changes to the Shotgun Creek, Falls Creek, or Rolling Rock Creek Diversions;
There would be no changes to the existing powerhouse, turbines, generators or tailrace;
There would be no changes to the existing 138 kilovolt transmission line; and
There would be no changes to any other mechanical, electrical, or transmission equipment
appurtenant to the Project.
FERC License Amendment Application ‐ Upper Hidden Basin Diversion PDEA – Page 14
Kodiak Electric Association, Inc. Draft
Terror Lake Hydroelectric Project, FERC Project No. 2743 June 2015
The Project is remote, and is not accessible via the Kodiak road system. Access to the Project site is only
possible by floatplane, helicopter, or boat. KEA maintains the Project’s existing dock/jetty area, located
at the head of Kizhuyak Bay for transporting material and personnel to and from the Project. The
dock/jetty area would be used to accommodate delivery of equipment and material for the construction
of the UHBD. Material would be offloaded at the dock/jetty area and trucked to the UHBD site using the
Project’s existing access road. The length of road from the dock/jetty to the area where a new UHBD
spur road would be constructed is approximately ten miles. A new access road spur would connect this
existing road to the new D‐West and D‐East diversion dams of UHBD.
Infrastructure support for temporary construction personnel already exists at the Project. A fully‐
functioning single‐family home can house a small construction crew, up to eight people. For larger sized
construction crews up to 30 people, an additional contractor camp is available onsite with hook‐ups for
electricity, potable water, and sewer. Once the UHBD is built, no additional KEA staff would be
necessary to operate or maintain the UHBD.
As a requirement for all contractor work conducted at the Project site, KEA employs standard Contract
Terms and Conditions ‐ Special Provisions Related to Safety and Environmental Protection (Contract
Terms and Conditions) to advise contractor personnel that they shall comply with all environmental
protection requirements while on Project Lands. A copy of the Contract Terms and Conditions
document is included in Appendix E – Measures and Plans, and a summary of these requirements is
provided in Table 2‐2 below.

2.1.3 Project Operation with Upper Hidden Basin Diversion
The UHBD components would be a basic, non‐mechanical design intended for gravity‐fed water
conveyance with minimal storage capacity behind two minor diversion dam structures. KEA has been
operating and maintaining three other similar diversions at the Project for 30 years. The Project has KEA
staff onsite continuously and the plant is controlled by the system dispatchers in KEA’s Dispatch Center
FERC License Amendment Application ‐ Upper Hidden Basin Diversion PDEA – Page 16
Kodiak Electric Association, Inc. Draft
Terror Lake Hydroelectric Project, FERC Project No. 2743 June 2015
located within the City. The Project will remain KEA’s primary source of electric power during adverse,
mean and high water years.
Figure 2‐1 below is a simplified diagram (not to scale) of the inflow and outflow of water throughout the
entire Project. A detailed analysis of how the additional inflows provided by the UHBD will be utilized by
the Project is also presented in Draft Exhibit B – Project Operation and Resource Utilization.
Figure 2‐1 Diagram of Water Inflow and Outflow at Terror Lake Hydroelectric Project
The Project’s total plant capacity will remain unchanged at 33.75 MW. A 100% plant capacity factor
equates to 296 million kWh. The Project’s average generating efficiency is 1,100 kWh per acre‐foot of
water. This generating efficiency rate will remain unchanged because there would be no changes to the
existing powerhouse, turbines and generators. The Terror Lake reservoir, Shotgun Creek Diversion, Falls
Creek Diversion, and Rolling Rock Creek Diversion (all to remain unchanged) currently provide on
average 123,000 acre‐feet of water resources annually to the Project for producing 135 million kWh of
energy. The proposed UHBD would provide an additional 30,000 acre‐feet of water to the Project each
year, equating to 33 million kWh of new energy production available for the Project. Therefore the
UHBD boosts the annual plant capacity factor by delivering additional water resources to the unchanged
Project powerhouse.
The proposed UHBD involves no change to the Terror Lake reservoir, dam or spillway design. With the
Terror Lake dam and spillway unchanged, the Project’s gross storage capacity and usable storage
capacity provided by the Terror Lake reservoir remains unchanged. The proposed UHBD would supply
additional water resources to the Terror Lake reservoir, but the normal maximum surface area (1,020
acres), normal maximum surface elevation (1,420 EL), and usable storage capacity (108,000 acre‐feet) of
the Terror Lake reservoir would remain unchanged. The current volume of the Terror Lake reservoir is

Kodiak Electric Association, Inc. Draft
Terror Lake Hydroelectric Project, FERC Project No. 2743 June 2015
adequate to utilize the additional inflows provided by the proposed UHBD under future projections of
electrical load demand. The Project has no license‐mandated lake level elevation rule curve. Terror
Lake’s minimum lake level elevation is 1,250 feet. Maximum lake level elevation is 1,420 feet, which is
the elevation of the Terror Lake dam spillway. The Project’s lake levels would continue to be managed
to ensure compliance with its Terror River instream flow requirements as per FERC License Article 43.
On average, the total future inflows to Terror Lake with the new inflows contributed by the proposed
UHBD are expected to be fully utilized by 2025. Kodiak’s electric load demand is growing, additional
hydropower production is needed, and the Terror Lake reservoir provides usable storage capacity.
Terror Lake’s lake level elevation is expected to be drawn down lower in the future than current lake
levels due to growing load demand and the need for the Project to provide usable storage capacity for
the UHBD inflow, but the minimum lake level would not be drawn down below the 1,250 EL minimum
and the maximum lake level would remain 1,420 EL. During the very wet years, there is always the
potential for lake spill if the Project’s available water supply outpaces KEA’s hydropower production
demand. In those wet year situations, the Terror Lake spillway has ample spillway capacity to pass
excess water resource as needed, including the additional inflows provided by the proposed UHBD. The
maximum inflow from the proposed UHBD to the Terror Lake reservoir would be limited by the
hydraulic capacity of the UHBD tunnel size, which at this stage of the conceptual design is estimated at
950 cubic feet per second (cfs). Any future change to Terror Lake’s annual lake level drawdown,
recharge, or spill rates has no impact to any of the Project’s license‐mandated compliance obligations.
With the exception of station service and transmission losses, all power generated by the Project is sold
to KEA’s Cooperative members. The full contribution of the UHBD inflows are expected to be fully
utilized by 2025.
At this time, KEA has no plans for additional Project developments other than the UHBD.
2.1.4 Project Benefits
The benefit of the UHBD is the supply of additional hydroelectric generation to KEA’s existing renewable
generation system with minimal equipment and infrastructure. This diversion is estimated to add 33
million kWh of energy annually to the Project, which goes straight into the KEA grid for the direct benefit
of KEA’s Cooperative Member‐Owners. This additional hydroelectric generation would allow KEA to
continue meeting growing loads, power a community‐wide shift in energy consumption from diesel fuel
to renewable electricity, and support Kodiak’s waterfront as the regional processing hub for Alaska’s
seafood industry.
The Pillar Mountain Wind Project and the Terror Lake Hydroelectric Project currently provide 99% of
KEA members’ electric needs with renewable wind and hydropower; however, KEA’s load growth has
intensified as the community displaces costly diesel fuel with clean, affordable electricity. A trend is
emerging with replacing old petroleum‐based furnaces to new electric‐based systems for space and
water heat. New home construction in town and on the US Coast Guard Base is installing electric‐based
systems for their water and space heating needs. Additionally, Kodiak’s seafood industry is poised for
significant expansion as Kodiak becomes a regional processing hub for Gulf of Alaska commercial
fisheries. A new seafood processing plant and a new electric‐powered port crane currently under
construction on Kodiak’s waterfront will become major sources of new load growth. Now is the time to
plan for adding more renewable energy to KEA’s system so these growing loads can continue to be met
with renewable sources of energy instead of diesel‐powered generation. Moving forward with the
UHBD development now allows KEA to be prepared for Kodiak’s future electrical demand by 2020.
FERC License Amendment Application ‐ Upper Hidden Basin Diversion PDEA – Page 18
Kodiak Electric Association, Inc. Draft
Terror Lake Hydroelectric Project, FERC Project No. 2743 June 2015
The UHBD would provide 30,000 acre‐feet of additional water resources to an existing hydropower
generating facility for KEA to provide a continuous supply of renewable energy to the Kodiak’s growing
electrical demand. Once the water resource from the UHBD flows into the existing Terror Lake
reservoir, an additional 33 million kWh of hydropower could be generated from the existing Project
powerhouse and fed directly into KEA’s existing grid without any operational changes or any other
capacity‐related modifications.
A detailed analysis of the economic savings and value the UHBD provides to KEA’s electric system is
presented in Draft Exhibit D – Statement of Costs and Financing. An analysis of the overall power and
economic benefits of the UHBD is provided in Section 4 ‐ Developmental Analysis of this PDEA.
2.2 Alternatives
There are only two sources of energy that can be added to KEA’s grid at this time: diesel fuel (the no‐
action alternative) and hydropower (the proposed action). The no action alternative (use of diesel fuel
for additional energy) is discussed below along with alternatives considered but eliminated from further
analysis.
Due to constraints of fuel availability and air quality regulations associated with burning diesel fuel,
diesel‐based generation is not a reasonable alternative for supplying electricity in a manner as
practicably as the UHBD. In light of this unique situation, KEA has determined that there are no other
reasonable alternatives to accomplish the stated purpose of adding more energy to KEA’s isolated grid
other than supplementing the available water supply at the Project with the UHBD.
2.2.1 No‐Action Alterative
Under the no‐action alternative, the Commission would deny the proposed construction and operation
of the UHBD. The Project would continue to operate under the conditions of the existing license.
The no‐action alternative would impair the ability of KEA to provide a continuous supply of renewable
energy for the benefit of the Kodiak community. Denial of the proposed UHBD would require KEA to
burn fossil fuel in its diesel generator units with the consequences of continued air emissions and
exposure of KEA members to high costs associated with diesel‐based generation. Denial of the
proposed UHBD would negate the efforts of the local community to modernize its energy infrastructure
with renewable energy and eliminate dependence on diesel fuel.
Reverting back to a dependence on barged‐in diesel fuel for local electric generation is not reasonable,
due to both economic and environmental costs. The future vision for the Kodiak community is to reduce
diesel fuel consumption, not return to it. Other renewable sources of energy are not feasible for KEA,
per the discussion in Section 2.2.2 below.
2.2.2 Other Alternatives Considered but Eliminated from Further Analysis
Other alternatives considered were: curtailing electric load demand, additional wind sources, new
hydropower generation facilities, new renewable energy sources (solar, tidal, run‐of‐river, and wave),
natural gas, coal, and nuclear power. These alternatives were not found to warrant further analysis for
the following reasons:
Curtailing electric load demand to below KEA’s 161 million kWh of available renewable energy
supply through conservation measures is not a reasonable solution to Kodiak’s specific energy
FERC License Amendment Application ‐ Upper Hidden Basin Diversion PDEA – Page 19
Kodiak Electric Association, Inc. Draft
Terror Lake Hydroelectric Project, FERC Project No. 2743 June 2015
circumstances, as it disregards the community‐wide shift away from diesel fuel consumption as
well as the growth occurring in the community’s industrial sector.
KEA is already pushing the technologic edge for wind energy penetration on its isolated micro‐
grid with battery and flywheel energy storage system integration, and cannot practically
engineer any more wind energy additions to its system.
KEA has investigated other potential sites on Kodiak Island for hydropower development;
however, it was determined not practical or cost‐effective to license, build and operate an
additional hydropower facility redundant to the existing generation and transmission
infrastructure of the Project.
There are no other viable diversion sites within the vicinity of the Project able to supply water
resources to the Project powerhouse.
The stable integration of variable energy forms such as solar, tidal, run‐of‐river hydroelectric,
and wave energy on KEA’s isolated micro‐grid has reached its maximum under KEA’s current
conditions. Further, tidal and wave energy generation technology remains in the testing phase,
and is not yet ready for utility‐scale deployment and operation.
There are no local sources of natural gas, coal, or nuclear power on Kodiak Island. It would not
be feasible to import natural gas, coal, or nuclear fuel to Kodiak due to transportation logistics,
high cost, safety precautions, and pollution control requirements.

3. Environmental Analysis
Information presented in this Section addresses the requirements of the NEPA Environmental
Assessment and the FERC regulation for the Environmental Exhibit E [18 CFR 4.51(f)]. Information
provided within this Section is based on KEA’s understanding of the resources at the pre‐filing stage of
consultation. Following the Joint Public/Agency Meeting on July 21, 2015 and comments received
during the period of public notice for this Draft Amendment Application, KEA will revisit and revise this
Section as necessary.
3.1 General Description of the Area Affected by the Proposed Action
3.1.1 Climate
Kodiak Island is known for its maritime climate, which is mild by Alaska standards. The climate is
dominated by a strong marine influence that produces frequent cloudy skies, moderately heavy
precipitation, and relatively cool mild temperatures year round.
In general, temperature patterns are characterized by cool summers and, compared to the rest of south
central Alaska, warm winters. The range between mean annual maximum and mean annual minimum
temperatures is small throughout the region. The average summer maximum temperatures occur in
July or August and range from 14 to 16 degrees Celsius (C). The coldest average winter minimum
temperatures drop to ‐5 to ‐7 degrees C in December. Average temperature differences between air
and water are greatest during fall and winter when the air is as much as 4 degrees C colder than the
water. This unstable condition results in air near the water surface being warmed, maintaining clouds at
a higher level than during spring and summer months when the air is warmer than the water.
Average rainfall is 67.6 inches per year and average snowfall is 78.7 inches per year. Precipitation
during periods of 24 hours or less can be heavy enough to cause flooding. February is the month with
the highest storm frequency and the greatest intensity of the Aleutian Low (a persistent low pressure in
the outer Aleutian Islands area), and July is the month with the lowest storm frequency and least
intensity of storms. Due to its elevation, steepness and terrain shading, snow can remain in the UHBD
area well into the month of June.
The hydrology in Hidden Basin Creek is characterized by a spring snowmelt as well as flashy, short
duration high flow events associated with heavy precipitation throughout the year. This is evident on
the hydrographs as steep spikes with very little ascending or descending lag time prior to or after the
peak flow. Persistent rain throughout the year saturates the soil and underdeveloped flood plains
through much of the basin resulting in an abrupt increase in the surface water discharge shortly
following precipitation events. During the early spring months it is not uncommon to receive heavy rain
on a deep snow pack, accelerating the rate of snow melt with latent heat of precipitation. Detailed
hydrographs of the Hidden Basin watershed are presented in ERM’s report, Hidden Basin Creek
Hydrology and Fisheries Report, Technical Report February 2015 which is provided in Appendix C –
Technical Reports.
3.1.2 Air Quality and Noise
Alaska is a State Implementation Plan‐approved state with jurisdiction over the national air quality
standards required by the Clean Air Act. The ADEC Air Permit Program has classified the air quality
surrounding the Project area as in attainment or unclassified with respect to the National Ambient Air
Quality Standards for particulate matter smaller than 10 micrometers, sulphur dioxide, nitrogen dioxide,
FERC License Amendment Application ‐ Upper Hidden Basin Diversion PDEA – Page 21
Kodiak Electric Association, Inc. Draft
Terror Lake Hydroelectric Project, FERC Project No. 2743 June 2015
and carbon monoxide. Federal Prevention of Significant Deterioration and Alaska air quality regulations
designate the Project area as a Class II area. (ADEC, 2015).
There is no noise monitoring data available and no monitoring is currently being collected. Due to the
remote site and the lack of development, there is no noise pollution within the Project area (FERC,
1981).
3.1.3 Topography
The landscape of northwest Kodiak Island is characteristic of glaciation as evidenced by long, narrow
fjords, and u‐shaped valleys. The Hidden Basin watershed in northcentral Kodiak Island originates in a
mountainous area east of the Terror Lake reservoir. Hidden Basin Creek is short and steep, originating
at an elevation of 2,500 EL and flowing south six miles into Hidden Basin, a natural saltwater lagoon,
before discharging into Ugak Bay and the Gulf of Alaska.
The proposed UHBD area would be located in the headwaters of the West Fork of Hidden Basin Creek.
(Refer to Figure A‐8, Hidden Basin Watershed.) The upper tributary geomorphology of Hidden Basin
Creek is characterized by high gradient step‐pool morphology, large boulder/bedrock substrate, rapids,
and waterfalls interspersed with pools and undercut banks. The proposed UHBD dams would be located
in this steep headwater area at approximately 1,530 EL where the tributaries are approximately 2,000
feet apart.
Downstream and below the proposed UHBD, the gradient steepens and drops over a waterfall canyon.
Below this sharp drop, the gradient flattens and the valley broadens in a meadow area. (Refer to Photo
B‐16, Aerial View of Upper Meadow.) The creek bed in this meadow area braids through fluvial
floodplains and surface flows are dominated by riffles over a smaller boulder/cobble substrate. Several
tributaries converge in this meadow, each contributing to surface flows. A tributary entering from the
southwest originates in glaciated mountains and contributes flow to the drainage year round.
Downstream of the meadow, the gradient steepens again through the lower canyon section of the West
Fork of Hidden Basin Creek and drops again over another tall vertical waterfall where the surface waters
are confined by steep bedrock cliff walls. (Refer to Photo B‐17, Lower Waterfall Barrier.) The gradient
substantially flattens again before exiting the canyon, transitioning from a boulder/bedrock step‐pool to
boulder/cobble riffle morphology.
The Middle, East and West Forks of Hidden Basin Creek join at the canyon mouth forming the mainstem
of Hidden Basin Creek. (Refer to Photo B‐18, Convergence of West, Middle and East Forks of Hidden
Basin Creek; and Photo B‐19, Aerial View of Mainstem of Hidden Basin Creek.) Several unnamed
tributaries provide additional surface water inputs along the three mile length of the mainstem. Two of
these mainstem tributaries contain lakes in their headwaters which provide storage to help maintain
base flows in the lower reaches of Hidden Basin Creek. The mainstem of Hidden Basin Creek has a
relatively flat gradient characterized by a meandering channel with multiple channel braids. The
substrate is dominated by alluvial materials consisting of small gravels interspersed with large cobbles
and boulders transported during peak flow events. The outfall is an inter‐tidal estuary where channel
depth varies dramatically between high and low tide.3 (Refer to photo B‐22, Aerial View of Mainstem
and Intertidal Reach of Hidden Basin Creek.)

February 2015 which is provided in Appendix C.

Kodiak Electric Association, Inc. Draft
Terror Lake Hydroelectric Project, FERC Project No. 2743 June 2015
3.1.4 Vegetative Cover
Tundra occurs above 1,500 EL and consists primarily of two closely related vegetative community types.
The more prevalent of these is a carex‐forb meadow found on moist slopes. Characteristic species are
carex sedges, artic bluegass (Poa arctica), lutkea (Luetkea pectinata), sweet coltsfoot (Petasites
hyperboreus), lupine (lupines sp.), coastal fleabane (Erigeron peregrinus), and Indian paintbrush
(Castilleja sp.). Ridgetops with well‐drained soil and barren, rocky patches support the fell field
community that has many of the same species as the carex‐forb meadow, but can be distinguished by
the presence of such plants as crowberry (Empetrum nigrum), alpine azalea (Kalmia procumbens),
Kamchatka rhododendron (Rhododendron camtschaticum), Alaska moss heath (Polytrichum sp.), and
blueberry (Vaccinium sp.). (FERC, 1981).
3.1.5 Land Development and Population Size
The Project is located in a remote area of northcentral Kodiak Island in the KIB approximately 25 miles
west of the City. (Refer to Figure A‐1, Site Location Map and Figure A‐2, KEA Service Area.) According to
the KIB GIS records (KIB GIS Website, 2015) there are seven privately owned lots equipped with tax‐
assessed buildings along the southwestern shores of Hidden Basin lagoon at the mouth of Ugak Bay
(Refer to Photo B‐24, Aerial View of Southwestern Shore of Hidden Basin Lagoon). These lots are
located west and south of the Hidden Basin Creek delta.
The Alaska Community Database Community Information Summaries (DCED, 2015) lists the 2010
Certified Population for the Borough as 13,592; of which the City population is 6,130, the US Coast
Guard Base is 1,301 and Port Lions is 194. The City is the eighth largest city in Alaska in terms of
population.
3.2 Scope of Cumulative Effects Analysis
Pursuant to the Council on Environmental Quality regulations for implementing NEPA at 40 CFR 1508.7,
cumulative effect is the impact on the environment which results from the incremental impact of the
action when added to other past, present, and reasonably foreseeable future actions regardless of
which agency (federal or non‐federal) or person undertakes such other actions. Cumulative impacts can
result from individually minor, but collectively significant, actions taking place over a period of time.
Actions to be considered include both hydropower and other land and water development activities in
the vicinity of the UHBD.
The UHBD area is remote and undeveloped. There are no developments in the Hidden Basin watershed.
There are no towns located within 15 miles of the Project. The only activity in the vicinity of the Project
are KEA staff who operate and maintain the Project equipment and facilities. There are no past land use
activities that have contributed to cumulative effects in the vicinity of the UHBD area. KEA is not aware
of any activities that may be potential actions qualifying as past, present, or reasonably foreseeable
future actions to be analyzed under this cumulative effects analysis.
The additional hydropower production made possible by the water resources of the UHBD saves 23,744
metric tons of greenhouse gas (GHG) from being emitted to the atmosphere each year by diesel‐
powered generation (no‐action alternative). The proposed UHBD is a reasonable approach to pollution
prevention and resource protection measure for climate and ocean acidification.

3.3 Proposed Action and Alternatives
3.3.1 Geology and Soils
There are two general rock types in the UHBD area: the light‐colored granitic rocks of the Kodiak
Batholith, and the darker‐colored metamorphic rocks of the Kodiak Formation. (Refer to Photo B‐15,
Geologic Contact.)
The Kodiak Batholith forms the high mountain ridge between the Terror Lake reservoir and the
proposed UHBD area. The proposed UHBD tunnel would cross directly through the Kodiak Batholith
ridge, and most of the tunnel excavation would be in the granitic rocks. (Refer to Figure A‐5, Geologic
Map of Project Area.) The granitic rocks of the Kodiak Batholith are strong and resistant to erosion.
The proposed UHBD tunnel would be inclined on a 1% slope from east to west, and is approximately 1.2
miles in length. The maximum rock cover above the tunnel would be approximately 1,060 feet. The
upstream portal would be located immediately west of the D‐West diversion dam with the invert at
approximately 1,530 EL. The downstream portal would be located adjacent to the southwest end of the
Terror Lake reservoir with an invert at approximately 1,467 EL. The tunnel size would be 12 feet in
diameter to convey up to 950 cfs of flow from the UHBD to the Terror Lake reservoir.
The area east of the mountain ridge is underlain by the somewhat weaker metamorphic rocks of the
Kodiak Formation. The Kodiak Formation rocks were originally fine‐grained sediments deposited
underwater that have been buried, compressed, densified, folded, and faulted during regional tectonic
deformation of Kodiak Island and intrusion of the Kodiak Batholith. Exposures of these rocks in the
UHBD area vary from highly foliated and fractured shale and slate to more blocky, quartz and feldspar‐
rich meta‐sandstones, greywackes, and argillites. In the highly fractured meta‐sedimentary rocks,
fracture spacing appears to be as little as inches apart, while the more blocky rocks have fracture
spacing of about a foot or more.
Crown Mountain is a granite mountain ridge that forms the eastern edge of the Hidden Basin
watershed. The contact between the granitic rocks of the Kodiak Batholith and Crown Mountain, and
the adjacent meta‐sediments of the Kodiak Formation can usually be identified by a change from light‐
colored to dark‐colored rocks, a change from steep to more gentle topography, and generally less
vegetative cover on the granitic rocks. The exact contact is often covered with soils and rocks which
have slid down the mountainside (colluvium), obscured by stream sediments (alluvium) or buried
beneath old glacial deposits (moraines). The intrusion of the viscous and hot granitic magma of the
Kodiak Batholith and Crown Mountain severely heated and baked the adjacent Kodiak Formation meta‐
sedimentary rocks in a process called “aureole metamorphism.” This process actually makes the rocks
denser and harder, although the fracture density may also increase compared to the same materials
outside of the baked zone. The width of the baked zone in the Kodiak Formation is reported to be from
less than a mile wide to over three miles wide regionally. Both the D‐West and D‐East dams and the
water conveyance between them would be either in or near this baked zone.
The proposed location for the D‐East diversion dam is a stream invert of 1,770 EL and the proposed
location for the D‐West diversion dam is a stream invert of 1,530 EL. These stream channels consist
mostly of gravel and cobbles with occasional large boulders. The channel banks consist of occasional
rock outcrops, gravel, cobbles and boulders. Above the banks, the channel side slopes varied, some
with tundra vegetation (Lachel, 2015). (Refer to Photos B‐4 and B‐5, D‐East Area.)
The proposed access road alignment would extend approximately four miles through the Kodiak
Formation, from the existing Project access road towards the D‐West and D‐East diversion dam sites.
Surface features range from rugged, mountainous terrain to wetlands. (Refer to photos in Appendix B.)

Terror Lake Hydroelectric Project, FERC Project No. 2743 June 2015
The final design specifications for the tunnel, diversion dams, and access road will be determined in
2017 after additional surveying, mapping, and geotechnical information is collected.
3.3.1.1 Resource Protection Measures
KEA will develop site‐specific quality control plans once the final engineering design is determined after
additional surveying, mapping and geotechnical information is collected. Detailed information on the
exact construction footprint and construction methods will be necessary in developing the site‐specific
Quality Control and Inspection Program (QCIP), Erosion and Sediment Control Plan (ESCP), APDES
Stormwater Permit, and CWA 404 Wetland Permit Authorizations.
As the sole owner and operator of the Project, KEA would be responsible for the overall management of
the UHBD construction process. KEA would provide an Environmental Compliance Monitor (ECM)
during construction to serve as the primary contact for communications among KEA and interested
entities, including the federal and state resource agencies and other entities as required. The ECM
would be periodically onsite during construction, and be available as needed to communicate with KEA
staff and contractor personnel regarding any identified issues. A description of the duties and authority
of the ECM is provided in Appendix E.
Protection and avoidance measures relating to erosion and sedimentation control are also specifically
addressed in KEA’s Contract Terms and Conditions document provided in Appendix E.
3.3.1.2 Record of Agency Consultation
This section will be completed in the Final PDEA.
3.3.2 Water Use and Quality
The total drainage area of the entire Hidden Basin watershed is 24.86 square miles. The total drainage
area of the West Fork portion of Hidden Basin Creek is 11.76 square miles, and the proposed UHBD area
in the upper reaches of that West Fork is only 3.82 square miles. The UHBD would divert 15% of the
overall Hidden Basin watershed drainage area. (Refer to Figure A‐7, UHBD Water Diversion; Figure A‐8,
Hidden Basin Watershed.)
The upper catchment area of the Hidden Basin watershed is estimated to drain approximately 30,000
acre‐feet of snow melt and rain. The UHBD proposal is to divert that surface water resource westward
through a mountain ridge tunnel toward the Project’s Terror Lake reservoir for hydropower generation.
The D‐West diversion dam catchment is estimated to provide approximately two‐thirds of the total
available water resources, and the D‐East diversion dam catchment would provide the remaining one‐
third. The maximum capacity of the conveyance pipe connecting the D‐East diversion dam to the D‐
West diversion would be approximately 250 cfs, and the combined total diversion capacity of the
subterranean diversion tunnel connecting the D‐West diversion dam to the Terror Lake reservoir would
be approximately 950 cfs. Surface water flow that exceeds the maximum capacity of the UHBD
conveyance pipe and tunnel would be spilled downstream over the diversion dam spillways into the
West Fork of Hidden Basin Creek.
Despite the 2,500 EL change in the watershed topography, diverting water from the upper reaches of
the Hidden Basin Creek would have no effect on surface water temperatures in the lower anadromous
reach of Hidden Basin Creek downstream. Surface waters flowing in the lower mainstem of Hidden
Basin Creek are actually cooler than the surface waters flowing in the upper watershed area because the
FERC License Amendment Application ‐ Upper Hidden Basin Diversion PDEA – Page 25
Kodiak Electric Association, Inc. Draft
Terror Lake Hydroelectric Project, FERC Project No. 2743 June 2015
mainstem of Hidden Basin Creek is fed primarily by groundwater, except during peak snowmelt and
large precipitation events. Groundwater upwelling occurs downstream of the confluence of the West,
Middle and East Forks of Hidden Basin Creek. Stream temperatures in the proximity of groundwater
upwelling zones are typically cooler than adjacent surface water and exhibit less fluctuation over a 24‐
hour period. Detailed information on water temperatures measured at gauging stations along Hidden
Basin Creek is included in ERM’s report, Hidden Basin Creek April 2013 – October 2014 Temperature
Analysis Report, Supplement to the Hydrology and Fisheries Technical Report, June 2015 which is
provided in Appendix C.
The results of ERM’s temperature analysis are consistent with the results of the Project’s post‐licensing
study that examined the effects of the Project’s operation on the surface and intragravel water
temperature of the Kizhuyak River. A report assessing effects from construction and operation of the
Project on the temperature and streamflow (Trihey and Associates, 1992) stated that:
“For all practical purposes, project effects on intragravel water temperatures are the same as
project effects on surface water temperatures.
There are small seasonal differences between the pre‐ and post‐project surface water
temperature near the USGS gaging stations on both [Terror and Kizhuyak] rivers.
In the Kizhuyak River, post‐project water temperatures during summer are generally about one
degree C cooler than pre‐project temperatures. There is a lesser difference between pre‐and
post‐project stream temperatures during the winter months.
Winter stream temperatures have changed little in the lower 1.5 miles of the Terror and
Kizhuyak rivers where the greatest amount of spawning activity has traditionally occurred.”
KEA operates three other diversion systems at the Project, and these three diversions have not resulted
in adverse effects in water quality downstream. Post‐licensing studies of the Project indicated that
water quality parameters on the Terror and Kizhuyak Rivers are essentially unchanged from pre‐project
conditions. Nutrient and sediment levels remained low and dissolved oxygen remained at or above
saturation. Water quality problems that arise are temporary and typically associated with natural
events such as storm flooding (FERC, 2004).
The proposed UHBD would not involve any changes to Terror Lake, the main reservoir for the Project.
With the Terror Lake dam and spillway unchanged, the Project’s gross storage capacity and usable
storage capacity provided by the Terror Lake reservoir remains unchanged. Terror Lake’s minimum lake
level elevation is 1,250 feet. Maximum lake level elevation is 1,420 feet, which is the elevation of the
Terror Lake dam spillway. The current volume of the Terror Lake reservoir is adequate to utilize the
additional inflows provided by the proposed UHBD under future projections of electrical load demand.
The Project has no license‐mandated lake level elevation rule curve. The Project’s lake levels would
continue to be managed to ensure compliance with its Terror River instream flow requirements as per
FERC License Article 43.
Detailed information on the hydrology of Hidden Basin Creek, including gauging data methodology and
hydrographs is provided in the ERM report, Hidden Basin Creek Hydrology and Fisheries Report,
Technical Report, February 2015, included in Appendix C. ERM’s supplemental report, Hidden Basin
Creek April 2013 – October 2014 Temperature Analysis Report, Supplement to the Hydrology and
Fisheries Technical Report, June 2015 is also provided in Appendix C. A detailed analysis of how the
additional inflows provided by the UHBD will be utilized by the Project is presented in Draft Exhibit B –
Project Operation and Resource Utilization.

3.3.2.1 Resource Protection Measures
KEA intends to acquire the water rights for the proposed UHBD activities prior to filing the Final
Amendment Application. KEA will comply with the terms and conditions of the water rights
appropriation.
KEA will develop site‐specific quality control plans once the final engineering design is determined after
additional surveying, mapping and geotechnical information is collected. Detailed information on the
exact UHBD design and construction methods will be necessary in developing a site‐specific QCIP, ESCP,
APDES Stormwater Permit, and CWA 404 Wetland Permit Authorizations.
As the sole owner and operator of the Project, KEA would be responsible for the overall management of
the UHBD construction process. KEA would provide an ECM during installation to serve as the primary
contact for communications among KEA and interested entities, including the federal and state resource
agencies and other entities as required. The ECM would be periodically onsite during construction, and
be available as needed to communicate with KEA staff and contractor personnel regarding any identified
issues. A description of the duties and authority of the ECM is provided in Appendix E.
As a requirement for all contractor work conducted at the Project site, KEA employs standard Contract
Terms and Conditions. Protection and avoidance measures relating to erosion and sedimentation
control and protection of aquatic resources are included in this document. A copy of the KEA Contract
Terms and Conditions document is provided in Appendix E.
KEA complies with CWA regulations 40 CFR 112 related to oil pollution prevention with KEA’s Spill
Prevention, Control, and Countermeasures (SPCC) Plan for the Project. Separate SPCC Plans specific to
any additional oil containers temporarily brought on‐site for UHBD construction would be required to be
prepared by the contractor, as is specified in the Contract Terms and Conditions document.
3.3.2.2 Record of Agency Consultation
ERM is currently engaged in a surface water stream gauging study in the Hidden Basin watershed. This
stream gauging activity is authorized under DNR Land Use Permit No. LAS 29042 and ADF&G Fish Habitat
Permit FH 13‐II‐0038 (included in Appendix D – Approvals and Documented Compliance with Federal
Statutes). KEA will continue to comply with the terms and conditions of these permits.
On April 10, 2015, KEA consulted with DNR Division of Land, Mining, and Water, Land Section and Water
Section staff regarding the process and application for water rights needed for the proposed UHBD. KEA
received guidance from DNR staff regarding the process and the application, and on May 5, 2015, filed
an Application for Water Rights as per AS 46.15 for approximately 45,000 acre‐feet of surface water to
be diverted by the UHBD to the existing Terror Lake reservoir. DNR advised KEA to request rights for an
amount of water greater than the amount of water estimated to be diverted because the quantity of
water can be easily adjusted down during the final water rights appropriations process, but it cannot be
easily adjusted up. Therefore, KEA requested 45,000 acre‐feet of water as a conservative buffer to the
30,000 acre‐feet of water estimated to be available at the proposed UHBD. A copy of the Application for
Water Rights is provided in Appendix D.
Certification pursuant to CWA Section 401 is required as per FERC regulation 18 CFR 4.38(a)(1). ADEC is
the lead agency for purposes of 401 Water Quality Certifications (WQC) for hydro projects pursuant to
the CWA; however, ADEC typically waives the requirement for the WQC for the type of action KEA is
proposing with the UHBD. On May 20, 2015, KEA submitted a request to ADEC Division of Water,
Stormwater and Wetlands Program to provide a statement regarding the WQC. On June 3, 2015, ADEC
issued a letter stating:

The ERM report, Hidden Basin Creek Hydrology and Fisheries Report, Technical Report February 2015
was provided to ADF&G on February 27, 2015; to NMFS on March 12, 2015; to DNR on May 5, 2015; and
to USGS on May 18, 2015. It is also provided to all Participants in Appendix C of this Draft PDEA.
This section will be further completed in the Final PDEA.
3.3.3 Wetlands
Wetlands in the vicinity of the proposed UHBD consist of palustrine emergent or scrub shrub wetlands
characterized by herbaceous vegetation and low or dwarf shrubs; depression bogs and marshes along
creek areas and riverine intermittent stream bottom; riverine upper perennial unconsolidated bottom;
and ponds. The riverine water channel types are either deep incised canyon channels, alpine rivulets, or
braided gravel bed streams. Ponds are typically very fine sand or silt substrate, many of which are
periodically dry (ERM, 2014).
The construction of the proposed UHBD will involve the filling of wetlands located in the vicinity of the
proposed UHBD. The exact location and size of affected wetlands, and the total volume of fill per
wetland unit is not known at this time.
A preliminary report on the wetlands within the vicinity of the proposed UHBD area is included in
Appendix B – Technical Reports. This preliminary report provides a cursory assessment; it is not a formal
delineation of wetlands. Due to the lower resolution information available at this time, the report
provided a conservative estimate of potential wetlands occurring in the UHBD vicinity, electing to
initially categorize lands with typical characteristics using the limited aerial imagery available at this time
as wetlands.
Additional information is currently being collected to refine the aerial imagery and elevation mapping
information for this remote area of Kodiak Island. This refined mapping and surveying data will be
utilized to develop a wetland delineation map.
3.3.3.1 Resource Protection Measures
As the sole owner and operator of the Project, KEA would be responsible for the overall management of
the UHBD construction process. KEA will comply with all terms and conditions of the CWA 404 Permit
and ADEC APDES Stormwater Permit, as required. Applications for those permits will be filed after more
information regarding the wetland mapping and construction footprint are better refined.
KEA would provide an ECM during installation to serve as the primary contact for communications
among KEA and interested entities, including the federal and state resource agencies and other entities
as required. The ECM would be periodically onsite during construction, and be available as needed to
communicate with KEA staff and contractor personnel regarding any identified issues. A description of
the duties and authority of the ECM is provided in Appendix E.

3.3.3.2 Record of Agency Consultation
On April 29, 2015, KEA consulted with USACE staff in the Alaska Division, Kenai Field Office regarding the
applicable CWA 404 permitting requirements and application process for the proposed UHBD. KEA
received guidance from USACE staff regarding the process and the application and determined that
additional information is required to delineate the area of affected wetlands before an application may
be filed. KEA intends to gather the necessary information and file a CWA 404 permit application with
the USACE in late 2016.
This section will be further completed in the Final PDEA.
3.3.4 Fishery Resources
No fish have been observed in the proposed UHBD area. The diversion dams, tunnel, and access road
would be sited in the upland area above two major waterfalls that serve as fish passage barriers. There
are no fish in the Terror Lake reservoir. Both the UHBD and Terror Lake reservoir are located in upland
mountainous areas above major waterfalls that serves as a fish passage barriers.
The three‐mile long mainstem section of Hidden Basin Creek is listed as Stream No 259‐41‐10077 in the
ADF&G Catalog of Waters Important for the Spawning, Rearing or Migration of Anadromous Fishes
(AWC). This reach of the Hidden Basin Creek mainstem is known to support chum salmon
(Oncorhynchus keta), pink salmon (Oncorhynchus gorbuscha), and Dolly Varden (Salvelinus malma). In
2014, minnow trapping associated with KEA’s recent research efforts confirmed coho salmon
(Oncorhynchus kisutch) was another anadromous fish species inhabiting the drainage seasonally. Coho
were not previously documented in the AWC for the mainstem of Hidden Basin Creek.
The upper limit of the anadromous reach is approximately three miles downstream of the proposed
UHBD area, below the two major waterfalls that separate the mainstem from the UHBD area. The
mainstem of Hidden Basin Creek forms at a canyon mouth where the West Fork joins with a Middle Fork
and East Fork of Hidden Basin Creek. This convergence area of the three major forks remains dry the
majority of the time due to downwelling of surface waters to subsurface flow underneath the porous
alluvial substrate. (Refer to Photo B‐20, Mainstem of Hidden Basin Creek.) Fish distribution is limited
spatially and temporally to intermittent, disconnected pools located on the mainstem of Hidden Basin
Creek, approximately one mile downstream from the confluence of the West, Middle and East Forks.
While renowned for their homing ability, salmon are also highly opportunistic and capable of exploiting
marginal or newly available habitat for their various life stages. The fact that portions of the mainstem
of Hidden Basin Creek experience discontinuous flow during late summer in some years suggests adult
pink and chum salmon (and potentially coho salmon) make use of the system opportunistically for
spawning under suitable flow conditions. Based on the prevailing gradient and substrate, most, if not all,
of this opportunistic spawning likely occurs in the mainstem. Although the West, Middle and East Forks
of Hidden Basin Creek have continuous flow, it is unlikely salmon spawn in them due to the steep
gradient, large boulder substrate and presence of waterfalls a short distance upstream from the
confluence with the mainstem. Spawning may occur at the mouth of the unnamed tributaries entering
the mainstem, but the substrate size and presence of barriers upstream on these tributaries is unknown
at this time. Fish occupying pools in the mainstem of Hidden Basin Creek that are seasonally dewatered
are not likely to survive the winter unless the pool has sufficient depth and food resources.
FERC License Amendment Application ‐ Upper Hidden Basin Diversion PDEA – Page 29
Kodiak Electric Association, Inc. Draft
Terror Lake Hydroelectric Project, FERC Project No. 2743 June 2015
The anadromous and resident fish found in the Hidden Basin Creek mainstem have likely adapted to the
stochastic nature of the surface water flows. Fish habitat in the dry stream channel of the mainstem is
limited spatially and temporally. During storm events or periods of high run‐off, fish may access the
otherwise dry reaches of the Hidden Basin Creek mainstem opportunistically but are likely to be trapped
in pools with limited resources such as dissolved oxygen or food, making them more vulnerable to
disease, competition, and predation.
The longitudinal movement of anadromous and resident fish in the mainstem of Hidden Basin Creek is
largely restricted to the stream reaches with available surface water. The last two miles of Hidden Basin
Creek appears to maintain surface water connectivity to the marine tidewaters of Hidden Basin Lagoon.
Water diversions at the UHBD are not likely to impact available fish habitat in this lower reach of the
watershed. The UHBD comprises only 15 percent of the overall Hidden Basin watershed area which is a
small portion of the surface water reaching the last two miles of the creek.
A small, isolated population of resident Dolly Varden has been observed in small numbers in the
meadow area located between the two large waterfalls on the West Fork of Hidden Basin Creek. Adults
collected at this location in 2014 were relative small in size (150 millimeters). Resident Dolly Varden are
well known to persist in waters above barriers similar to the large waterfall in the West Fork of Hidden
Basin Creek. Throughout their range, Dolly Varden are often the only species present above fish
migration barriers and likely benefit from the absence of competition for resources.4
3.3.4.1 Resource Protection Measures
KEA employs standard Contract Terms and Conditions to advise them on specific environmental
protection requirements, including terrestrial resource protection measures, while on Project lands.
Contractor personnel are not allowed to use the Project area for recreational purposes, such as hiking,
hunting, or fishing. Contractor personnel are to confine their activities to the Project area relevant to
the construction of the UHBD. Protection and avoidance measures relating to aquatic resources are also
specifically addressed.
As the sole owner and operator of the Project, KEA would be responsible for the overall management of
the UHBD construction process. KEA would provide an ECM during installation to serve as the primary
contact for communications among KEA and interested entities, including the federal and state resource
agencies and other entities as required. The ECM would be periodically onsite during construction, and
be available as needed to communicate with KEA staff and contractor personnel regarding any identified
issues. A description of the duties and authority of the ECM is provided in Appendix E.
3.3.4.2 Record of Agency Consultation
ERM is currently engaged in a surface water stream gaging study in the Hidden Basin watershed. This
stream gaging activity is authorized under DNR Land Use Permit No. LAS 29042 and ADF&G Fish Habitat
Permit FH 13‐II‐0038. KEA will continue to comply with the terms and conditions of these permits.
ERM conducted fish presence, absence and distribution surveys along the West Fork and mainstem of
Hidden Basin Creek from the alpine headwaters to the lower mainstem reach. The 2014 fish collection
activities were authorized under ADF&G Fish Resource Permit No. SF2014‐153. KEA and ERM fulfilled all
terms and conditions of this permit, including providing ERM’s report, Hidden Basin Creek Hydrology and

Fisheries Report, Technical Report February 2015 to ADF&G on February 27, 2015 which detailed the
results of the fish presence, absence and distribution survey. KEA also nominated the addition of
juvenile coho salmon to Stream No. 259‐41‐10077, Hidden Basin Creek on Kodiak Island due to
observations of its presence in the lower reaches of Hidden Basin Creek during the 2014 study.
As a follow‐up to the 2014 fish presence, absence and distribution survey, ERM will conduct additional
presence, absence and distribution surveys of resident Dolly Varden in the upper reaches of the West
Fork of Hidden Basin Creek. Fish collection activities associated with this study are authorized under
ADF&G Fish Resource Permit No. SF2015‐145. KEA and ERM will continue to comply with the terms and
conditions of this ADF&G permit.
On April 1, 2015, KEA met with ADF&G staff in a pre‐filing meeting to discuss KEA’s intention to develop
the UHBD, and to discuss the three‐stage consultation process involved with the Application for Non‐
Capacity Amendment to FERC License No. 2743.
The ERM report, Hidden Basin Creek Hydrology and Fisheries Report, Technical Report February 2015
was provided to NMFS on March 12, 2015.
This section will be further completed in the Final PDEA.
3.3.5 Terrestrial Resources
Six terrestrial mammal species are native to Kodiak Island, or have colonized it since the last glacial
period (5,000 to 10,000 years ago). They are the Kodiak brown bear (Ursus arctos middendorfi), ermine
(Mustela erminea), river otter (Lutra canadensis), red fox (Vulpes vulpes), tundra vole (Mifrotus
oeconomus), and little brown bat (Myotis lucifugus). All of these species occur in the Terror Lake
Hydroelectric Project area (FERC, 1981).
The primary mammal species of concern is the Kodiak brown bear. Kodiak’s most well‐known species
appears to be distributed throughout the Island, and generally emerges from denning during the month
of May. Breeding occurs in the period following emergence and generally ends by late June. Around
mid‐July, bears disperse from their alpine feeding range and move down to the lower elevations of the
Island’s river valleys to feed on fish. Denning occurs in mid‐November, and the lower Terror River Valley
includes some of the best denning habitat (FERC, 1981).
ADF&G initiated a bear research program in 1982 concurrent with the construction of the Project. The
primary objective of the bear research program was to document bear activities in the Terror, Kizhuyak,
and Elbow Creek drainages during and immediately after construction. Results of intensive aerial
surveys conducted in 1987 and 1997 yielded density estimates of 234 independent bears (adults or
subadults) per 1,000 square kilometer (or 0.6 bears per square mile), and 276 independent bears per
1,000 square kilometer (or 0.7 bears per square mile), respectively. The ADF&G investigation concluded
that KEA’s Project construction had little adverse impact on the local bear population. It also noted that
as long as salmon resources were conserved, standard bear safety practices were followed, and access
along the Project access roads were carefully managed, operation of the Project was not anticipated to
harm bears (Van Daele, 2010).
Other mammal species have been imported accidentally or purposefully to the Island by man.
Sitka black‐tailed deer (Odocoileus hemionus sitkensis) was first introduced to Kodiak Island in 1934 and
are abundant throughout the Project area. The deer make vertical migration from sea level to alpine
areas in response to climatic conditions and the availability of food. As fall arrives, the deer generally
migrate from the high elevations to feed on remaining succulent vegetation at lower elevations. Deer
winter in the lower river drainages, generally below 500 EL (FERC, 1981).
FERC License Amendment Application ‐ Upper Hidden Basin Diversion PDEA – Page 31
Kodiak Electric Association, Inc. Draft
Terror Lake Hydroelectric Project, FERC Project No. 2743 June 2015
Between the period 1929 to 1931, 23 beavers (Castor canadensis) were introduced to the Island and
released to lakes and streams. Beaver can be found in habitat throughout the Island, including the
Terror and Kizhuyak river drainages. Watchout Creek, in the lower Kizhuyak drainage, contains the most
significant sign of beaver habitation (FERC, 1981).
Kodiak Island supports a diversity of waterfowl as well as pelagic and shore birds. Although no major
waterfowl production areas occur in the Project area, Kodiak Island’s river deltas provide suitable
habitat for numerous bird species. Project personnel report that bald eagles (Haliaeetus leucocephalus)
are observed year‐round in the Terror Lake Hydroelectric Project area, and they occasionally forage in
the Kizhuyak River in late July through September, when pink salmon are present.
3.3.5.1 Resource Protection Measures
KEA employs standard Contract Terms and Conditions to advise contractor personnel on specific
environmental protection requirements, including terrestrial resource protection measures, while on
Project lands. Contractor personnel are not allowed to use the Project area for recreational purposes,
such as hiking, hunting, or fishing. Contractor personnel are to confine their activities to the Project
area relevant to the construction of the UHBD. Contactors may not bring firearms to the Project site,
and there is no motorized wheeled access authorized on Project lands other than official use vehicles.
Encounters with wildlife may occur in the Project area; however, KEA’s Terms and Conditions clearly
stipulate that animals are not to be harmed in any way. All eagles, their eggs, and nests are protected
from disturbance. No vehicles or equipment may interfere with beaver dams.
Contractor personnel are required to participate in a Bear Safety Orientation provided by KEA to
mitigate the possibility of conflict between personnel and a bear. In accordance with KEA’s Bear Safety
Program, no food shall be left outside unattended, garbage handling will be done by incineration, and
there is no feeding of wildlife. A bear incident reporting form is to be completed upon any significant
and abnormal encounter with a bear in the Project area, which is then forwarded to the ECM for ADF&G
notification.
As the sole owner and operator of the Project, KEA would be responsible for the overall management of
the UHBD construction process. KEA would provide an ECM during installation to serve as the primary
contact for communications among KEA and interested entities, including the federal and state resource
agencies and other entities as required. The ECM would be periodically onsite during construction, and
be available as needed to communicate with KEA staff and contractor personnel regarding any identified
issues. A description of the duties and authority of the ECM is provided in Appendix E.
3.3.5.2 Record of Agency Consultation
This section will be completed in the Final PDEA.
3.3.6 Threatened and Endangered Species
Based on consultation with the USFWS, there are no listed, proposed, or candidate species under the
ESA or their designated critical habitat identified to occur within the vicinity of the proposed UHBD.
Likewise, based on consultation with the NMFS, there are no species under NMFS jurisdiction and listed
as endangered or threatened under the ESA that are known or suspected to occur in the proposed
UHBD area, nor is there designated critical habitat for any such species in the proposed UHBD area.

Terror Lake Hydroelectric Project, FERC Project No. 2743 June 2015
3.3.6.1 Resource Protection Measures
Due to the lack of use of the UHBD area by ESA listed, proposed, or candidate species, there are no
proposed measures specific to ESA. Refer to discussion of other resources for protection and avoidance
measures associated with wildlife protection.
3.3.6.2 Record of Agency Consultation
On March 12, 2015, KEA submitted Requests to be Designated Non‐Federal Representative pursuant to
Section 7 of the ESA to consult with the USFWS and NMFS regarding any listed and candidate species.
On April 17, 2015, FERC issued a letter to USFWS and NMFS informing the agencies of KEA’s designation
as their non‐federal representative for the purpose of conducting informal consultation pursuant to
regulation 50 CFR 402.08 implementing Section 7 of the ESA. On April 28, 2015, KEA requested species
lists from the USFWS and NMFS.
On June 1, 2015, USFWS staff directed KEA to utilize its automated Information for Planning and
Conservation (IPaC) online system (http://ecos.fws.gov/ipac/) for attaining information on federally
endangered or threatened plant and animal species, as well as plant and animal species of concern that
are known or suspected to occur in the UHBD area. The automated IPaC system provided KEA with a
report that there are no listed species or designated critical habitat in the proposed UHBD planning
area. Appendix D includes a copy of KEA’s species request letter to USFWS along with the USFWS IPaC
automated response report.
On June 1, 2015, KEA also received an e‐mail from the NMFS stating that none of the listed species
under the NMFS’ jurisdiction would be found in the proposed UHBD area. The e‐mail also stated that
the lack of ESA listed species in the area precludes the need to consult informally with NMFS under
Section 7 of the ESA for development of KEA's proposed UHBD as part of the FERC‐licensed Project.
Appendix D includes a copy of KEA’s species request letter to NMFS along with their e‐mail response.
On June 9, 2015, copies of the findings and correspondence related to Section 7 ESA consultation were
filed with the FERC under separate cover.
3.3.7 Cultural Resources
During the Project’s original FERC licensing proceeding, KEA conducted reconnaissance archeological
surveys and test excavations within the proposed Project area of potential effect. The reconnaissance
surveys at the then‐planned location of the dock/jetty and access road from Kizhuyak Bay to the
powerhouse resulted in discovery of two prehistoric sites (Righter, 1979). Further test excavations at
KOD‐138 showed it to be a severely eroded, small site covering less than 100 square meters, and with
shallow cultural deposits. Test excavations at KOD‐190 showed it to be a larger site spread over a 675
square meter area on an outcrop 6 meters above sea level. Surface indications of ten housepits were
present, as well as indications of a late Kachemak Period occupation, 100 BC to AD 1100, and a later
Koniag occupation, AD 1100 to ca. 1760. Both sites were interpreted as seasonally occupied fish camps
(Righter and Jordan, 1980). Test excavations and analysis recommended that site KOD‐138 was not
eligible for listing on the National Register of Historic Places (NRHP). Site KOD‐190, a stratified, multi‐
component prehistoric site, was recommended by investigators as eligible for the NRHP.
KEA, SHPO, Western Region of the Advisory Council on Historic Preservation (ACHP), and FERC
concurred with the recommendations and a mitigation plan for the sites located along Kizhuyak Bay.
FERC License Amendment Application ‐ Upper Hidden Basin Diversion PDEA – Page 33
Kodiak Electric Association, Inc. Draft
Terror Lake Hydroelectric Project, FERC Project No. 2743 June 2015
KEA implemented mitigation measures, including moving the planned access road further away from the
sites, relocating the dock/jetty, posting notices to contractor personnel regarding cultural resources, and
periodic monitoring of the site conditions. The archeological sites are located outside of the Project
boundary on lands owned by the Afognak Native Corporation (ANC).
The cultural resource surveys conducted during the Project’s original licensing studies did not locate any
cultural resources in the vicinity of Terror Lake or Hidden Basin. The UHBD would be constructed in an
interior location on Kodiak Island at a high elevation, which was difficult to access from coast prior to
the Project’s road construction. There are few resources to attract human use of this remote area, and
salmon cannot reach the area.
Northern Land Use Research, Inc. (NLUR) prepared the report, Review of Cultural Resources in Vicinity of
Kodiak Electric Association Terror Lake Project – FERC No. 2743 Upper Hidden Basin Diversion Project at
the request of KEA. The report describes the locations of the protected sites, presents an overview of
the proposed UHBD, and makes recommendations for measures appropriate to the proposed action.
The report was provided to SHPO on May 1, 2015 for their review and comment. The Alaska SHPO
reviewed NLUR’s report and issued a letter dated May 28, 2015 with concurrence that a finding of no
historic properties affected is appropriate for the proposed license amendment for the UHBD.
3.3.7.1 Resource Protection Measures
As recommended in the NLUR report and reiterated by the Alaska SHPO in a letter dated May 28, 2015,
KEA agrees that (1) no cultural resource survey is required for the UHBD area due to the low probability
of encountering cultural resources based on the Project location and the negative findings from previous
research; (2) the existing mitigation measures will remain in place and be updated as necessary in FERC
licensing for the UHBD; (3) KEA will continue using the existing contract language and procedures
regarding the inadvertent discovery of human remains or cultural resources during construction; (4) KEA
will continue to provide contractor personnel training on cultural resources and human remains and the
protections given under state and federal laws; (5) KEA, Alutiiq Museum and Archaeological Repository,
and ANC continue the successful archaeological stewardship monitoring of cultural resource sites; and
(6) KEA initiate Section 106 consultation with the Alaska SHPO by providing this report and a summary of
measures to be taken during the construction of the UHBD.
KEA will continue its contractor personnel education and cultural resource awareness program. A copy
of the KEA Contract Terms and Conditions document is provided in Appendix E.
KEA executed a Memorandum of Understanding (MOU) with ANC and the Alutiiq Museum and
Archaeological Repository to conduct the required period monitoring of site KOD‐190. The MOU
provides for periodic monitoring and reporting on the status of KOD‐190 by a qualified archaeologist,
consultations with ANC, and annual reporting on the monitoring program. The MOU is an innovative,
collaborative approach to cultural resource stewardship. A copy of the MOU is included in Appendix E.
These mitigation measures provide adequate protection to KOD‐190. Construction and operation
activities associated with the proposed UHBD would not take place anywhere near the KOD‐190 site.
KEA policy, procedures, and training prevent contractor personnel from approaching anywhere near the
site. Additionally, ongoing periodic monitoring of the site condition would verify that these measures
are working to protect site KOD‐190. Implementation of these measures would assure that no historic
properties will be adversely affected by UHBD.

3.3.7.2 Record of Agency Consultation
On March 12, 2015, KEA submitted Requests to be Designated Non‐Federal Representative pursuant to
Section 106 of the NHPA to consult with the Alaska SHPO regarding historical properties potentially
affected by the proposed UHBD. On April 17, 2015, FERC issued a letter to SHPO informing the agency of
KEA’s designation as their non‐federal representative for the purpose of conducting informal consultation
pursuant to the regulation 36 CFR 800.2(c)(4) implementing section 106 of the NHPA.
On May 1, 2015, the NLUR report, Review of Cultural Resources in Vicinity of Kodiak Electric Association
Terror Lake Project – FERC No. 2743 Upper Hidden Basin Diversion Project was transmitted to the SHPO
pursuant to Section 106 of the NHPA as Privileged Information. SHPO responded in a letter dated May
28, 2015 with agreement that a finding of no historic properties affected is appropriate for the proposed
license amendment for the UHBD. A copy of this letter is provided in Appendix D. On June 9, 2015,
copies of the NLUR report and SHPO letter were filed with the FERC under separate cover as Privileged
Information.
3.3.8 Land Use
The UHBD area is located 30 miles west of the City. There are no towns located within 15 miles of the
Project, or any other developments in the Terror or Kizhuyak watersheds. The only activity in the vicinity
of the Project are KEA staff who operate and maintain the Project equipment and facilities. According to
the KIB GIS records, there are seven privately owned lots equipped with tax‐assessed buildings along the
southwestern shores of Hidden Basin Lagoon located at the mouth of Ugak Bay. This area is over six
miles south of the proposed UHBD area, on the shores of marine tidewaters to the west of the Hidden
Basin Creek delta outlet. (Refer to Photo B‐24, Aerial View of Southwestern Shore of Hidden Basin
Lagoon.)
The Project occupies land owned by ANC, KEA, KIB, State of Alaska, and Kodiak National Wildlife Refuge.
(Refer to Figure A‐6, Land Ownership Map.) ANC owns lands occupied by the Project’s existing
dock/jetty and portions of the Project’s existing access road. KEA is authorized to access these areas
with an easement lease granted by ANC for a term of 50 years (April 2, 1982 – April 2, 2032), extending
beyond the November 1, 2031, expiration date of the FERC license. This easement lease was filed with
FERC on April 24, 1986. KEA and KIB own lands occupied by the Project’s powerhouse facilities. KEA is
authorized to access KIB lands in accordance with the agreement, Authorization to Enter on Kodiak
Island Borough Land to Design, Construct and Maintain the Terror Lake Hydroelectric Project signed on
March 26, 1982. The State of Alaska owns the submerged lands at the Project’s existing dock/jetty, and
KEA is authorized to use those submerged lands with DNR lease agreement ADL No. 206462. The
remaining portion of the Project east of the Terror watershed (with exception of 136 acres for the
portion of the transmission line corridor near the City of Kodiak), is owned by the State of Alaska. KEA is
authorized to occupy these State lands with DNR lease agreement ADL No. 204024.
The Project’s licensed boundary currently occupies 4,282 acres of federal lands. Of that total amount,
136 acres of the Project boundary encompass lands occupied by the Project’s transmission line
connecting Project power to the City of Kodiak. The other 4,146 acres of the federal land within the
Project boundary encompass the Terror Lake reservoir and western portions of the Project access road
and tunnel.
The majority of the proposed UHBD area is located on lands owned by the State of Alaska, managed by
the DNR. By necessity of connecting the UHBD water resources to the existing Terror Lake reservoir,
some of the new UHBD would need to be constructed on federal land already occupied by the Project
and administered by the Kodiak National Wildlife Refuge. A portion of the proposed UHBD tunnel
FERC License Amendment Application ‐ Upper Hidden Basin Diversion PDEA – Page 35
Kodiak Electric Association, Inc. Draft
Terror Lake Hydroelectric Project, FERC Project No. 2743 June 2015
corridor would need to occupy 1.9 additional acres of federal land administered by the Kodiak National
Wildlife Refuge outside the current Project boundary. This 1.9 acre corridor of expanded Project
boundary on federal land would encompass a subterranean tunnel, completely underneath a mountain
ridge.
A detailed map of the proposed revisions to the FERC‐licensed Project boundary, including the location
of the 1.9 additional acres of federal land, are provided in Draft Exhibit G – Project Map.
3.3.8.1 Resource Protection Measures
KEA intends to acquire all necessary land use authorizations for the proposed UHBD activities prior to
filing the Final Amendment Application. KEA will comply with the terms and conditions of these land
use authorizations.
As a requirement for all contractor work conducted at the Project site, KEA employs standard Contract
Terms and Conditions to advise them that they shall comply with all environmental protection
requirements while on Project Lands. A copy of the KEA Contract Terms and Conditions document is
provided in Appendix E.
3.3.8.2 Record of Agency Consultation
ERM is currently engaged in a surface water stream gaging study in the Hidden Basin watershed. This
stream gaging activity is authorized under DNR Land Use Permit No. LAS 29042. KEA will continue to
comply with the terms and conditions of this Land Use Permit.
On April 10, 2015, KEA consulted with DNR Division of Land, Mining, and Water, Land Section and Water
Section staff regarding the process and application for land access needed for the proposed UHBD. KEA
received guidance from DNR staff regarding the process and the application, and on April 14, 2015, filed
an Application for Easement as per AS 38.05.850 for the portions of the proposed Upper Hidden Basin
Diversion located on State land. A copy of the Application for Easement is provided in Appendix D.
On April 22, 2015, KEA consulted with USFWS Kodiak National Wildlife Refuge staff regarding the
process for land access needed for conducting pre‐filing geotechnical studies and for constructing the
tunnel that would connecting the water resource of the proposed UHBD to the Terror Lake reservoir.
This section will be further completed in the Final PDEA.
3.3.9 Recreation and Aesthetic Resources
There is minimal recreational demand in the Project area due to difficult access and concerns over
minimizing brown bear and human conflicts. Public use of the Project area is essentially non‐existent
because there are ample opportunities for recreation at other more accessible areas of Kodiak Island
(Refer to Figures A‐9, Recreation Sites Near Project; and Figure A‐10, Existing Recreation on Kodiak
Public Road System.)
FERC exempted the Project from filing the Hydropower Development Recreation Report, FERC Form 80,
because of the lack of recreational use at the Project. Due to its low hazard potential and remote
location, KEA has also remained exempt from Emergency Action Plan requirements since its original
construction.
FERC License Amendment Application ‐ Upper Hidden Basin Diversion PDEA – Page 36
Kodiak Electric Association, Inc. Draft
Terror Lake Hydroelectric Project, FERC Project No. 2743 June 2015
3.3.9.1 Resource Protection Measures
For the rare instances that the public approaches the Project area, an informational kiosk and sign‐in
book are located at the entrance of the access road from the Kizhuyak Bay dock/jetty on lands owned by
the ANC. The information presented at the kiosk was developed in consultation with ANC staff.
Public Safety devices utilized in the Project area consist of gates, signs, and fences. These devices are
not specifically relevant to the UHBD area, but to the overall Project area. A copy of the Project’s Public
Safety Plan, written in accordance with 18 CFR 12.4 and 18 CFR 12.42 is provided in Appendix E.
Due to the remote location of the Project and lack of public use, no aesthetic resource measures are
proposed.
3.3.9.2 Record of Agency Consultation
In correspondence dated June 17, 1997, FERC acknowledged that available information indicates there is
little or no potential for recreational use at the project. Therefore, in accordance with 18 CFR 8.11(c),
FERC has exempted KEA from further filing of the Form 80 for the above‐cited project, until further
order of the Commission.
3.3.10 Socioeconomic Resources
The City is the economic, transportation, and governmental center of the island archipelago area. It is a
Home Rule City with an elected Mayor and Council, which employs a City Manager. The City ranks
eighth in terms of population, in comparison to other boroughs and unified municipalities of Alaska. The
KIB is a second‐class borough incorporated September 24, 1963, and operates under a Manager form of
government with an elected Assembly.
Access to Kodiak Island is by air or water. Alaska Airlines and Ravn Air provide regular scheduled service.
Andrew Air, Island Air and Servant Air also provide scheduled air taxi flights to outlying communities,
and charter services are available. Float plane facilities are also prevalent in Kodiak, as airport facilities
or landing strips throughout the archipelago are not widely available. The road system on the Island
follows the coastlines from Cape Chiniak and Narrow Cape north through the City of Kodiak to
Monashka Bay. There is no rail service. The Alaska Marine Highway System provides passenger, vehicle
and cargo ferry service connecting Kodiak to Alaska’s mainland road system. Ferry transit from the City
to the nearest mainland ferry terminal in Homer, Alaska is typically eight hours in duration during calm
weather and smooth seas.
Marine terminals in Women’s Bay provide service to several freight carriers, freight forwarders and
consolidators, construction contractors, and the fishing fleet. The terminal has warehousing, yard storage,
and crane services. The cost of shipping to Kodiak is a significant factor in the overall cost of living for the
region, and improving the affordability and reliability of shipping in Kodiak is essential to the region’s
economy. Pier III is the primary cargo freight port facility for the Kodiak Island region with nearly every
commodity imported or exported from Kodiak Island’s communities’ passing across Pier III. KEA has
partnered with the City to repower Pier III’s inefficient diesel‐powered crane with a new electric crane.
The older diesel‐powered crane was restricting the loading capabilities of Pier III to smaller specialized
vessels, and kept the region vulnerable to limited transportation options and inflated shipping costs. KEA’s
efforts to help modernize Kodiak’s regional port hub with a bigger, faster, more energy‐efficient electric
crane allows more local seafood products to be exported to the global market, and better food and
building materials to be brought into Kodiak’s remote island communities.

Kodiak Electric Association, Inc. Draft
Terror Lake Hydroelectric Project, FERC Project No. 2743 June 2015
The majority of the KIB population resides in the area directly within or adjacent to the City. KEA
provides electricity to approximately 6,000 meters on Kodiak Island (Refer to Figure A‐2, KEA Service
Area.) The availability of electric power generated primarily by KEA’s integrated hydro‐wind generation
system provides electric service at a cost that is buffered against the extreme swings in diesel fuel cost.
KEA’s load demand is growing because the community is developing new infrastructure based on KEA’s
renewably‐generated electricity as the local energy solution. The direct benefit to the membership is
not only in fuel‐free, emission‐free renewable power, it is in the stable, predictable cost of electric
energy. While other utilities around the nation are struggling with rate increases, KEA provides stable, or
slightly lower, electric rates to its Cooperative membership. The US median rate for electric revenue per
kWh sold from 2000 to 2013 has increased 49%, while KEA’s has seen a mere 1% increase. The US
Median electric revenue per kWh has increased 18.9% from 2007 to 2013, while KEA’s has decreased
10.4% during that same period (NRUCFC KRTA, 2007‐2013). The economic benefits of KEA’s renewable
energy vision are substantially positive for the Kodiak community.
The Port of Kodiak is home to Alaska’s largest and most diversified fishing fleet and is constantly ranked
in the top three largest fishing ports in the US in terms of value landed. It has more than 650 boat slips
and three commercial piers that can handle vessels up to 1,000 feet. More than one‐third of the jobs in
Kodiak are directly related to the fishing industry, in either the harvesting or processing sectors. There
are 789 active permit holders in the local commercial fisheries. Landings to the Port of Kodiak in 2012
were 382 million pounds, with a wholesale value of $178.6 million. Groundfish, primarily pollock and
cod, is the largest segment of Kodiak’s fisheries in terms of volume and wholesale value, accounting for
approximately 75% of the region’s commercial catch and 49% of the region’s total wholesale value.
Salmon is the next largest with about 29%; halibut at 17%; crab at 3%; and herring at 2%. Kodiak’s
seafood processing plants employ approximately 3,226 people with a combined payroll of over $47
million. The largest shoreside seafood processors include Trident, International Seafoods of Alaska,
Ocean Beauty, and North Pacific Seafoods. Subsistence and sport fishing are also prevalent in the region
(Kodiak Chamber of Commerce, 2013).
The electricity required to process and freeze seafood products drives KEA’s electrical load demand.
Now that the local seafood processing industry is powered with KEA’s affordable and stably‐priced
electricity, Alaskan seafood companies are choosing Kodiak as their regional processing hub to expand
their operations. KEA is pleased to support the growth of Kodiak’s primary commercial industry as these
expanded facilities bring more jobs and revenue into the local community.
Kodiak’s role as a major commercial fishing port and one of the nation’s largest producers of seafood is
complemented by it being a regional center for transportation, governmental offices, timber, and
tourism. The local hospital ranks among the top employers, and the City, KIB, state, and federal
agencies also provide local employment. Kodiak Island is also home to the nation’s largest US Coast
Guard (USCG) Base equipped with both aviation and maritime fleets. KEA is proud to assist the USCG in
their efforts to meet their federal facility renewable energy requirements. KEA allocates Renewable
Energy Credits to the membership, including the USCG Base without additional costs. As a Cooperative,
KEA’s membership already owns the renewably‐powered electric grid and it is KEA’s honor to share all
of the value‐added benefits and renewable energy credits with the member owners it serves.
KEA’s goal is to continue using renewable wind and hydro energy resources for 95% of the community’s
electricity needs. To illustrate how integrated the local community is in KEA’s vision statement, the
Kodiak Chamber of Commerce embarked on an Economic Development Project “salmon wind water”
branding campaign in 2011 to redefine sustainable seafood. The local salmon processors are proud to be
part of an electric grid that is embracing clean energy and moving away from reliance on fossil fuel‐
based power. In July 2010, a local fish processing plant in Kodiak also began marketing its product by
touting its connection to sustainable energy via Kodiak’s Pillar Mountain wind farm on its packaging.

Kodiak Electric Association, Inc. Draft
Terror Lake Hydroelectric Project, FERC Project No. 2743 June 2015
KEA’s success with implementing sustainable, renewable energy solutions has drawn the attention of
numerous media outlets that travel to Kodiak to learn how a small rural electric cooperative could make
such a huge difference in renewable energy and micro‐grid technology development. Numerous
magazine and news articles have been written about KEA’s leadership and success in laying out a
strategy to move the local community away from fossil fuels and toward cost effective renewable
energy solutions. KEA has been awarded the 2014 State Leadership in Clean Energy Award by the Clean
Energy States Alliance; the 2014 Clean Energy Innovator of the Year Award by the Renewable Energy
Alaska Project; the 2009 Wind Cooperative of the Year Award by the National Rural Electric Cooperative
Association and US Department of Energy; the 2009 Cornerstone Award by the Kodiak Chamber of
Commerce; and was a nominee for the Utility Scale Innovation 2013 Award from the Energy Storage
North America.
The proposed action would have no direct impact on local government revenues. KEA is a rural electric
cooperative, and as a 501(c)12 not‐for‐profit organization, KEA is exempt from local, state, and federal
taxes. Boosting the Project’s power production with additional water resources provided by the
proposed UHBD would, however, indirectly benefit the local governments by enhancing the Kodiak
economy as a whole with stable cost of renewable power and continuation of marketing opportunities
associated with renewable energy. When the cost of power is more stable and predictable with
renewable sources of energy, KEA’s cooperative members, including the City and KIB, remain in a better
position to plan and budget for their power costs. KEA’s renewable energy portfolio provides marketing
opportunities for Kodiak businesses that use KEA’s electricity to manufacture their products, and if these
new marketing campaigns result in increased business, then the proposed action could boost Kodiak’s
local government tax revenue. Enhancing the existing Project with the UHBD would have a direct
positive effect on the community and future sustainability of Kodiak Island.
The proposed action would have no direct impact on local government expenditures. There are no
municipal services, such as road, police, fire or medical services at the remotely located Project site.
Infrastructure support for temporary construction personnel already exists at the Project. As the sole
owner and operator of the Project, KEA is responsible for maintaining and repairing the Project’s
infrastructure including the dock/jetty, access roads, buildings, utilities, and fire protection systems. A
fully‐functioning single‐family home can house a small construction crew up to eight people. For larger
sized construction crews up to 30 people, an additional contractor camp is available onsite with hook‐
ups for electricity, potable water, and sewer. KEA staff and hired contractor personnel at the Project
site are responsible for conducting themselves in a safe and professional manner. If a medical
emergency were to arise at the Project, flight evacuation to a hospital or other treatment facility would
be provided at KEA’s expense. Construction of the UHBD is a temporary process that would not result in
a significant change to Kodiak’s population. Once built, the UHBD would not require additional KEA staff
to operate at the existing Project.
3.3.10.1 Resource Protection Measures
As the sole owner and operator of the Project, KEA would be responsible for the overall management of
the UHBD construction process. KEA would provide an ECM during installation to serve as the primary
contact for communications among KEA and interested entities, including the federal and state resource
agencies and other entities as required. The ECM would be periodically onsite during construction, and
be available as needed to communicate with KEA staff and contractor personnel regarding any identified
issues. A description of the duties and authority of the ECM is provided in Appendix E.

4. Developmental Analysis
4.1 Power and Economic Benefits of the Project
The UHBD provides substantially positive benefits to the Kodiak community because the only other
available alternative for power generation is diesel fuel. Economic benefits of the UHBD are therefore
determined by comparing the costs to produce the amount of power made available by the water
resources of the proposed UHBD versus diesel‐based generation. Compared to the diesel alternative,
the net present value (NPV) for the UHBD is over $129 million. Considering the relatively small size and
scope of the proposed project that level of benefit is highly material, and is a significant value for the
Kodiak community.
KEA proposes to have the UHBD operational by 2020. KEA’s system load demand in 2020 is expected to
be 18 million kWh greater than KEA’s currently available hydropower and wind energy supply.
Therefore, without the additional water resources provided by the UHBD, the 18 million kWh of
additional load demand would require KEA to revert back to diesel‐generated power. KEA’s diesel‐
generation efficiency is 14.2 kWh per gallon of diesel fuel. KEA’s historical average cost of diesel fuel is
$3.14 per gallon. In addition to the direct cost of diesel fuel, diesel engine maintenance costs average
4¢ per kWh. KEA’s annual budget assumes a fuel and maintenance cost inflation rate of 3%. Based on
these diesel generation efficiency rates and costs, the direct fuel costs for generating 18 million kWhs
without the UHBD is approximately $4.5 million, plus an additional $818,825 in diesel engine
maintenance cost.
Table 4‐1 Summary of UHBD Costs and Savings Incurred within First Year of Operation
Year 1 Costs Year 1 Savings
Debt cost $4,518,764 Savings from avoided fuel cost $4,526,605
Maintenance cost $ 150,000 Savings from avoided engine maintenance $ 818,825
Total Cost in Year 1 $4,668,764 Total Savings in Year 1 $5,345,430
NET SAVINGS in Year 1 = $676,666
Even with the expenses of constructing this new diversion, including debt and maintenance, the first
year benefits of the UHBD would net $676,666 in savings. While this is very positive, it is the lowest year
of net savings due to it being the lowest production needed from UHBD to supplement KEA’s growing
loads. The annual cost‐saving benefits of hydropower continue to escalate from $676,666 in Year 1, to
$5.7 million in Year 5 of UHBD operation as KEA’s electrical load grows. This is due to the hydropower
being basically a fixed‐cost asset while diesel fuel prices continue to inflate. The expected continual
growth in savings provided by the UHBD is illustrated in Figure 4‐1.

Kodiak Electric Association, Inc. Draft
Terror Lake Hydroelectric Project, FERC Project No. 2743 June 2015
Figure 4‐1 Annual Savings Provided by UHBD
UHBD’s project life is 50 years; however, based upon KEA’s experience with its financing institutions, it is
highly probable that the amortization period for financing the UHBD would be 30 years. Therefore, the
economic projection is set at 30 years. Even at that limited time frame, the simple payback will occur
before 15 years of operation has occurred. There is very little operation and maintenance cost for the
UHBD as it is simply a water conveyance diversion. It utilizes the Project’s existing Terror Lake reservoir,
main power tunnel, penstock, powerhouse, substation, and transmission line.
Figure 4‐2 illustrates the cumulative benefit of the UHBD in its lower and stable cost of power versus the
high cost of diesel power, which is the no‐action alternative. By Year 15, the cost of diesel is three times
more expensive than the hydroelectric power made available by the water resources of UHBD.

Terror Lake Hydroelectric Project, FERC Project No. 2743 June 2015
The power and economic benefits provided by UHBD and the overall Project have a significant
cumulative positive effect over time. Over the 30 year financing term, a total of 66,947,372 gallons of
diesel fuel are expected to be saved from the additional hydropower production made possible by the
water resources of the UHBD. The direct savings from that avoided fuel cost are $380 million, plus the
additional $69 million in savings from avoided diesel engine maintenance cost. Not only does the UHBD
supply stable‐cost power for the community for years to come, it supplies an extremely cost‐effective
source of power that becomes even more cost‐effective every year after its first year of operation.
4.1.1 Operation of Project with Upper Hidden Basin Diversion
A significant benefit of this UHBD is the simplicity of its operation. It is a diversion that utilizes all
existing aspects of the Project with no moving parts. In 1978, the original engineers of the Project
recommended this diversion as a future development as it was found to be the most economical means
of increasing hydropower production whenever the growth in power demand in Kodiak justified it
(Retherford, 1978). The Project already has three other diversions: Shotgun Creek Diversion, Falls Creek
Diversion, and Rolling Rock Creek Diversion. KEA has 30 years of experience successfully operating and
maintaining these low maintenance features.
KEA is in full compliance with all requirements of Part 12 of the Commission’s dam safety regulations.
The Project has been operating for 30 years under the terms and conditions of the existing license.
During this time, Commission staff has conducted operational inspections focusing on the continued
safety of the structures, efficiency, and safety of operations, compliance with terms of the license and
proper maintenance. In addition, the Project has been inspected and evaluated every 5 years by an
independent consultant; most recently in August 2010 with a consultant’s safety report filed on
December 10, 2010. As a required part of the project development and review process for the proposed
UHBD, KEA will provide the final engineering design and associated construction quality control and
Project safety plans to the FERC PRO Division of Dam Safety and Inspections for their approval prior to
finalizing construction contracts. The final engineering design and associated construction quality
control plans are expected to be ready for FERC PRO review in 2017.
With the exception of station service and transmission losses, all Project power is sold to KEA’s
Cooperative members. The full contribution of the UHBD is expected to be fully utilized by 2025.
Refer to Section 2.1.3 for additional discussion of how the UHBD would be operated with the UHBD. A
detailed analysis of how the additional inflows provided by the UBH diversion will be utilized by the
Project is also presented in Draft Exhibit B – Project Operation and Resource Utilization.
4.2 Comparison of Alternatives
4.2.1 KEA's Proposal
The UHBD will divert water from the upper reaches of the Hidden Basin watershed to the existing Terror
Lake reservoir for additional hydropower production at the existing Project powerhouse. The UHBD
boosts KEA’s renewable energy supply by utilizing existing infrastructure and enhancing its potential for
annual energy generation. The proposal would not change the authorized installed capacity of the
Project; however, the additional water resources added to Terror Lake from this diversion are expected
to increase average annual generation by an additional 33 million kilowatt‐hours.
KEA proposes to construct two new concrete face rockfill dams approximately 30 feet high and 250 feet
wide within an eastern and western tributary branch of the West Fork of Hidden Basin Creek,
approximately six miles upstream of Hidden Basin Lagoon and Ugak Bay on the eastern side of Kodiak
FERC License Amendment Application ‐ Upper Hidden Basin Diversion PDEA – Page 43

Island, Alaska. Surface water from the diversion dam on the eastern tributary (D‐East) would flow
through a half‐mile long, five foot diameter underground pipe to the diversion dam on the western
tributary (D‐West). From there, surface water from both diversion dams would flow by gravity through
a 1.2 mile long, 12 foot diameter tunnel through a mountain ridge to Terror Lake, the main reservoir for
the Project. The proposed diversion dams would include broad crested weir sections that would provide
adequate spillway capacity during periods of heavy rain and snow melt in excess of the diversion’s
conveyance pipe and tunnel hydraulic capacity. Any amount water flow that exceeds the capacity of the
UHBD conveyance pipe and tunnel would be spilled downstream over the diversion dam spillways into
the West Fork of Hidden Basin Creek. The proposed UHBD would also include a four mile long spur road
off of an existing road to provide access for constructing and maintaining the new diversion.
The total cost of the project is estimated at $79,992,000. KEA’s annual debt and maintenance for the
UHBD Project is $4,668,764, with the significant majority being the debt service. Based on KEA’s 30‐year
operation of three other similar diversion structures already in operation at the Project, there is very
little annual maintenance required for the proposed UHBD. Once the UHBD is built and fully utilized,
the annual savings will exceed $6.5 million. The economic benefits provided by the UHBD for the
communities of Kodiak are significantly positive.
4.2.2 No‐Action Alternative
Under the no‐action alternative, the Commission would deny the proposed construction and operation
of the UHBD. The Project would continue to operate under the conditions of the existing license.
Denial of the proposal would effectively close the door on KEA’s renewable energy innovations and
negate the substantial, community‐wide efforts to reduce consumption of fossil fuels. The no‐action
alternative would impair the ability of KEA to provide a continuous supply of renewable energy to power
the community’s growing energy needs, thereby hindering the modernization of Kodiak’s infrastructure.
Denial of the UHBD proposal means that KEA must revert back to burning fossil fuels in its diesel units to
power its growing electrical load and expose its Cooperative members to the consequences of
increasing air emissions and high energy costs.
4.3 Cost of Environmental Measures
No environmental measure costs are proposed for the UHBD.
Construction and operation of the UHBD is not anticipated to result in significant environmental impact.
The purpose of the proposal is to divert a small portion of the watershed’s resources from the upper
reaches of the West Fork of Hidden Basin Creek for renewable energy production. The UHBD would be
similar to existing diversion structures currently in operation at the Terror Lake Hydroelectric Project,
and for the past 30 years KEA has proven that it can successfully and responsibly construct and operate
these types of hydropower facility components in this environment without adverse effects.
The UHBD comprises only 15% of the overall Hidden Basin watershed size, and is located in an upper
alpine area where no fish have been observed. The diversion of water from the upper portions of the
Hidden Basin watershed is not likely to have an impact on the anadromous habitat located three miles
downstream, below two major waterfall barriers. No threatened or endangered species are found in
the proposed UHBD area. There would be minimal change in the facility’s aesthetic appearance, and
there is essentially no public use in the Project vicinity.
Constructing the new diversion dams and access road will require structures to be placed within
tributary creeks and wetlands; however, this activity is routinely authorized under license and permit

conditions that specify best management practice requirements to minimize potential impacts to the
aquatic and terrestrial environments. The minor impacts incurred by temporary construction activities
are far outweighed by the long‐term benefits associated with enhancing renewable energy
infrastructure with this hydropower diversion.
4.4 Greenhouse Gas Reduction
Diesel‐powered generation is a source of carbon dioxide (CO2) pollution that contributes to climate
change and ocean acidification. The more gallons of diesel fuel KEA burns for electric power generation,
the more carbon pollution is introduced into the global atmosphere. The purpose of constructing and
operating the UHBD is to reduce KEA’s consumption of diesel fuel.
KEA’s diesel‐generation efficiency is 14.2 kilowatt‐hours per gallon of diesel fuel, which means that the
amount of renewable energy provided by the proposed UHBD (33 million kWh) equates to 2.3 million
gallons of diesel fuel that otherwise would have to be burnt annually to generate an equivalent amount
of power with diesel‐fired power generators. Based on the Environmental Protection Agency’s (EPA)
emission factor for CO2 as specified in 40 CFR 98.33, burning 2.3 million gallons of diesel fuel would
release 23,744 metric tons of GHG emissions to the atmosphere.
The additional hydropower production made possible by the water resources of the UHBD therefore
saves 23,744 metric tons of CO2 from being emitted to the atmosphere each year. To help put that
amount of pollution into context, Kodiak would have to remove 4,999 passenger vehicles5 or more than
two‐thirds of all passenger vehicles registered in Kodiak6 off the road to achieve the same level of
carbon emission reduction. The benefits of the proposed UHB are not just economical savings, it is a
reasonable approach to pollution prevention.
It is KEA's responsibility to supply reliable and affordable electricity to a community that prides itself on
living in harmony with its surrounding environment. KEA’s grid is experiencing an increase in load
demand because the community is switching its source of energy from fossil fuels to locally‐ and
renewably‐generated electricity. KEA strives to continue powering Kodiak’s future energy needs with
renewable energy. The UHBD is the most cost‐effective and feasible approach for KEA to achieve its
vision: Endeavor to maintain 95% of energy sales with cost effective renewable power
solutions for the future of our members and the community.

EXECUTIVE SUMMARY
This report is the culmination of a two year study which included hydrology monitoring
in 2013 and 2014 and a fish presence / absence study in 2014. The study quantified the
cumulative volume of surface water available in the 2014 water year (WY) for the
proposed Upper Hidden Basin Diversion Project. The Upper Hidden Basin Diversion
Project would supplement the available water supply for the Terror Lake Hydroelectric
Project by diverting surface water in the upper reaches of the HBC watershed and
convey it to the existing Terror Lake reservoir. The study also quantified the volume of
surface water at additional gage locations distributed longitudinally in Hidden Basin
Creek (HBC) from the alpine headwaters near the proposed hydropower diversion area
to the creek’s lowland mainstem approximately one mile (mi) from the marine
environment. Lastly, the study documented the presence / absence of fish species
longitudinally near the respective gage locations and relative to two waterfalls in Upper
HBC serving as potential barriers to upstream fish migration. Prior to this study effort,
little was known about the hydrology, fish habitat, and fish distribution in HBC. The
study succeeded in improving the local knowledge and understanding of the HBC
hydrology and fish distribution in the drainage.
Four stream gaging stations were established longitudinally in HBC from the
headwaters to the mainstem reach upstream of the confluence with the marine
environment. Gage D-West is located on the main reach of Upper HBC (West Fork
Upper HBC) near an initially proposed location for the D-West Diversion dam. This
reach of stream is characterized by a step-pool high gradient slope, steep bedrock banks,
and large boulder/bedrock substrate. Gage D-East is located on a tributary to the main
reach of Upper HBC (East Fork Upper HBC) approximately 650 feet (ft) in elevation
below the D-East Diversion dam. The stream reach where D-East Diversion is located is
characterized by a step-pool high gradient slope, steep undercut banks with
overhanging vegetation, and large boulder/bedrock substrate. Gages 2 and 3, located
downstream in the West Fork of HBC and the mainstem, respectively, were established
to quantify the proportion of water remaining in lower HBC to assess the potential
impact of diverting water at the Upper Hidden Basin Diversion Project to Terror Lake.
Periodic field discharge measures were used to build stage–discharge rating curves for
each gage location. Rating curves were then used in conjunction with continuous surface
water elevation measurements to build hydrographs representing the real-time surface
water discharge at each of the four gage locations. This report includes surface water
data collected from April 23, 2013 to October 8, 2014.
The surface water discharge data measured in Upper HBC at Gage D-East and Gage D-
West was used to calculate the annual available water resources for the proposed Upper
Hidden Basin Diversion Project. Gage D-East and Gage D-West are located at a mean
elevation of 1,420 ft and have drainage areas of 1.26 square miles (mi2) and 3.42 mi2,
respectively, comprising approximately 19% of the total HBC watershed. Following
Hidden Basin Creek Hydrology and Fisheries Report KEA
ERM 2 2/11/2015
initial engineering analysis and field surveys, the location of the diversion dams was
moved upstream of the gage locations causing an overall decrease in the total catchment
area size from 4.7 mi2 to 3.8 mi2 or 15% of HBC watershed.
The cumulative water yield available for the Upper Hidden Basin Diversion Project
delivery to Terror Lake was approximately 29,503 acre feet (ac ft) for the full 2014 WY.
Much of the data used to generate the water yields at the Upper Hidden Basin Diversion
Project were collected at adjacent gaging stations and extrapolated to the respective
diversion locations using the proportion of catchment area size. This approach was
validated by comparing initial discharge data to historic United States Geological Survey
(USGS) gage data. The magnitude, frequency, and duration of mean daily discharge
were similar between the USGS data and the Gage D-West locations.
Surface water discharge does not increase in a downstream direction between the
headwater tributaries and the mainstem of HBC despite a substantial increase in
catchment area including the ungaged inputs from the Middle and East Forks of HBC
along with several unnamed tributaries. The proportion of surface water discharge
contributed directly from the Upper Hidden Basin Diversion Project to the mainstem of
HBC cannot be accurately quantified through surface water stream gaging alone due to
the porous substrate in the mainstem of HBC causing a longitudinal decrease in surface
flows compared to upstream locations. Several ungaged catchments contribute both
surface water and groundwater to the mainstem HBC. The Middle and East Forks of
HBC comprise substantial drainage areas along with several unnamed tributaries not
accounted for in the surface water measurements alone.
An alternative approach was used to compare the proportion of discharge contributed
from each headwater area in HBC by calculating the discharge based on drainage area
size for each catchment. Mean daily discharge for USGS Gage 15297100 and 15297110
was used to synthesize hydrographs for the ungaged catchments in HBC for
longitudinal comparisons of surface water yields. Surface water discharge in the
synthesized hydrograph is typically 2.5 times greater at Gage 2 compared to discharge
measures for the Upper Hidden Basin Diversion Project. Likewise, the synthesized
discharge at Gage 3 further downstream is an additional 2 times greater than Gage 2
throughout the year. The addition of the Middle Fork and East Fork in the discharge
yield analysis indicates the Upper Hidden Basin Diversion Project comprises a much
smaller percentage of the overall water yield for Gage 3. The surface water data collected
in 2013 and 2014 did not include the Middle and East Forks in the overall hydrology
balance sheet. Surface water measures at Gage 3 in 2013 and 2014 also failed to quantify
the contributions from the Middle and East Forks because much of the contribution from
these catchments, like the West Fork, go subsurface and are not measurable using
surface water sensors alone.
Along with surface water hydrology, a fish presence / absence study was conducted in
2014. Minnow traps were set at each stream gage location in May, July, August, and
October to better understand the longitudinal distribution of fish in HBC. In addition,
Hidden Basin Creek Hydrology and Fisheries Report KEA
ERM 3 2/17/2015
adult distribution was documented through helicopter flights and ground observation
for adult spawners. Potential fish passage barriers were documented through aerial
reconnaissance. Fish passage barriers in the drainage include two waterfalls and the
mainstem regularly dewatered except during peak flow events following storms and
spring run-off. Waterfall A is approximately 50 ft high located between Gage 2 and field
discharge Site 1b. Waterfall B is a smaller and is located directly upstream of the
confluence with Upper East Fork and Upper West Fork of HBC. The dewatered stream
channel occurs in the mainstem between Gage 2 and Gage 3.
In May 2014 a total of 5 fish were collected in minnow traps consisting of Dolly Varden
and a sculpin species. All fish collected in May 2014 were downstream of Waterfall A. In
July 2014, a total of 19 Dolly Varden were collected, two were trapped above Waterfall A
at Site 1b. In August 2014, 17 juvenile coho salmon and 42 Dolly Varden were collected.
Only one Dolly Varden was collected above Waterfall A at Site 1b. In October 2014, 39
juvenile coho salmon and 66 Dolly Varden were collected at Gages 2 and 3. No fish were
collected upstream of Waterfall A in October. No fish were collected or observed at the
Gage D-West or Gage D-East on any of the sampling events.
Fish distribution in the West Fork of HBC is influenced by the waterfall located in the
lower reach of the West Fork (Waterfall A) as well as the fragmented habitat in the
mainstem due to subsurface flows. Fish habitat between Gage 2 and Gage 3 is limited
spatially and temporally. The dry stream channel in this reach presents a migration
barrier for adults and juveniles. During storm events or periods of high run-off, fish
may access the mainstem of HBC between Gage 2 and Gage 3 opportunistically but are
likely to be trapped in pools with limited resources (dissolved oxygen, food) making
them more vulnerable to disease, competition, and predation. Anadromous and
resident fish are predominantly found in the reach downstream of Gage 3 with
continuous surface water connectivity all the way to the marine confluence at Hidden
Basin Bay. Water diversions at the Upper Hidden Basin Diversion Project are not likely
to impact available fish habitat in the reach below Gage 3. The Upper Hidden Basin
Diversion Project comprises only 15 percent of the overall HBC watershed area. Surface
water flows downstream of Gage 3 are continuous.

1. INTRODUCTION
This report summarizes a two-year study of Hidden Basin Creek (HBC) focusing on the
hydrology longitudinally from headwaters to the lower elevation mainstem as well as
fish presence / absence longitudinally in the watershed relative to potential upstream
migration barriers. Kodiak Electric Association, Inc. (KEA) initiated a preliminary
hydrology study in 2013 to assess the potential water resource for a proposed
hydropower diversion from the upper portion of the HBC watershed to Terror Lake.
The diverted water would supplement Terror Lake’s water supply and be used to
generate power from the existing Terror Lake Hydroelectric Project, (Federal Energy
Regulatory Commission Project No. 2743).
The hydrology study quantifies annual flows in the HBC system allowing KEA to
evaluate the quantity of water, and generating capacity to assess the viability of the
Upper Hidden Basin Diversion Project. The hydrology assessment includes the
following components: 1) installation and servicing of continuous-recording stage
(water surface elevation) monitoring devices at four gaging locations longitudinally in
HBC; 2) measurement of stream discharge associated with these gages; 3) construction
of a rating curve from which continuous stage measurements were used to construct a
stream flow record; 4) annual hydrographs ; and 5) the development of cumulative
water yields for calculating power generation potential.
In 2013, three continuous recording stream gaging stations were established in HBC to
measure discharge longitudinally. In 2014, the upper most stream gage was moved 1.5
miles (mi) downstream. A fourth gage was added in 2014 in upper HBC to document
flows in a tributary.
A fish presence / absence study was initiated in the 2014 study season using minnow
traps deployed at each of the stream gage locations in combination with aerial and foot
surveys to document adult spawning distribution. Potential barriers to upstream fish
migration were documented through aerial reconnaissance and photographs.
This report provides an analysis of the available hydrology resource available for
hydropower development based on the field work completed in 2013 and 2014 and
subsequent hydrology data analysis for those respective gage locations including rating
curves, surface water discharge, and cumulative water yields. The hydrology analysis
also incorporates available data from the United States Geological Survey (USGS) data
record, which was found to correlate well with recently collected data, as well as surface
water estimates based on watershed size. The report also includes a summary of the
fish habitat conditions longitudinally in HBC based on the presence / absence study
conducted in 2014.
1.1. Project Description
KEA conducted the hydrology and fisheries resource assessment to evaluate the
potential for constructing a diversion system on the upper reaches of the West Fork of
Hidden Basin Creek Hydrology and Fisheries Report KEA
ERM 5 2/11/2015
HBC. The Upper Hidden Basin Diversion Project would supplement the available water
supply for the Terror Lake Hydroelectric Project by capturing additional snow melt and
rain in the upper reaches of the HBC watershed and convey it to the existing Terror Lake
reservoir. Structural components for the proposed project would consist of two dam
embankments connected by a channel or pipe, an intake structure connected to
subterranean tunnel that would run through a mountain ridge, and a gravel road for
construction and future maintenance access. The diversion components would be a
simple, non-mechanical design intended for un-manned water conveyance. Combined
total diversion capacity from the D-West diversion and D-East Diversion would be
approximately 900 to 950 cfs. Surface water flow that exceeds the capacity of the Upper
Hidden Basin Diversion Project conveyance and tunnel will be spilled downstream over
the diversion dams into the West Fork of HBC. Once the water from the Upper Hidden
Basin Diversion Project flows into the Terror Lake reservoir, the additional hydropower
would be generated from the existing Terror Lake Hydroelectric Project and fed directly
into the KEA grid.
KEA provides electricity to approximately 5,800 meters on Kodiak Island in a service
area that includes the region in and around the City of Kodiak, the U.S. Coast Guard
Base, Bell’s Flats, Chiniak, Pasagshak, and Port Lions. The Terror Lake Hydroelectric
Facility is the primary source of KEA’s energy supply. It is located approximately
twenty mi southwest of Kodiak. Water is diverted from the Terror Lake reservoir to the
generating facility through an approximately five-mile long power tunnel. The Terror
Lake powerhouse contains three vertical axis impulse Pelton-type turbine generator
units for a total generating capacity of 33.75 megawatts.
Enhancing water availability to Terror Lake with a new diversion would allow KEA’s
future electrical load growth to be continually powered with renewable energy. KEA is
committed to pursuing renewable energy sources, and the project will help Kodiak’s
goal to have 95% of their electrical needs supplied by renewable energy. KEA’s
renewable energy vision drives the pursuit of the Upper Hidden Basin Diversion Project
as the next step for KEA’s expansion of available renewable energy supply to meet
Kodiak’s future energy needs.
1.2. Study Area
The landscape of Northwest Kodiak Island is characteristic of glaciation as evidenced by
long, narrow fjords, and u-shaped valleys. The HBC drainage in the Northern portion of
Kodiak Island originates in a mountainous area East of Terror Lake. HBC is short and
steep, originating at an elevation of 2,500 ft above mean sea level. The stream flows in a
predominantly south and southwest direction for approximately six miles before
discharging into Hidden Basin which is at the northwestern end of Ugak Bay.
Due to its elevation, steepness and terrain shading, snow can remain in the headwaters
area well into the month of June. Kodiak Island is known for its maritime climate which
is mild by Alaska standards. Average rainfall is 67.6 inches (in) per year and average
snowfall is 78.7 in per year (National Oceanic and Atmospheric Administration (NOAA)
2003).
Hidden Basin Creek Hydrology and Fisheries Report KEA
ERM 6 2/11/2015
The Upper Hidden Basin Diversion Project is located in the headwaters of the West Fork
of HBC referred to as Upper HBC. The Upper HBC catchment area includes the Upper
West Fork and Upper East Fork of the West Fork HBC. Upper HBC is characterized by
high gradient step-pool morphology, large boulder/bedrock substrate, and cataracts
(rapids and waterfalls) interspersed with pools and undercut banks. The proposed
Upper Hidden Basin Diversions are located in this steep headwater area at a mean
elevation of 1,530 ft where the two forks (the Upper West Fork and Upper East Fork of
the West Fork) are approximately 2,000 ft apart.
Downstream of Waterfall B, below the proposed Upper Hidden Basin Diversion Project,
the gradient flattens and the valley broadens in an upper meadow area. The creek bed in
this meadow area braids through fluvial flood plains and surface flows are dominated
by riffles over a smaller boulder/cobble substrate. Several tributaries converge in this
meadow, each contributing to surface flows. A tributary entering from the southwest
originates in glaciated mountains and contributes flow to the drainage year round.
Downstream of the upper meadow, the gradient steepens through the lower canyon
section of the West Fork of HBC and drops again over a 50 ft vertical waterfall where the
surface waters are confined by steep bedrock cliff walls. The gradient substantially
flattens again before exiting the canyon, transitioning from a boulder/bedrock step-pool
to boulder/cobble riffle morphology.
The Middle Fork and East Forks of HBC join together with the West Fork of HBC at the
canyon mouth forming the mainstem of HBC. Several unnamed tributaries with steep
gradients also provide surface water inputs along the 3.1 mile (mi) length of the
mainstem. Two of these tributaries contain lakes in their headwaters which provide
storage to help maintain base flows. The HBC mainstem has a relatively flat gradient
characterized by a meandering channel with multiple channel braids. The substrate is
dominated by alluvial materials consisting of small gravels interspersed with large
cobbles and boulders transported during peak flow events. The outfall is an inter-tidal
estuary where channel depth varies dramatically between high and low tide. HBC flows
south six miles into Hidden Basin, a natural saltwater lagoon, before discharging into
Ugak Bay (Figure 1-1).
The total drainage area for HBC from the confluence with the marine environment is
approximately 25.5 square miles (mi2). The Upper Hidden Basin Diversion Project
would divert surface water from 3.8 mi2 of the Upper HBC drainage into Terror Lake.
This comprises only 15% of the total watershed area in HBC (Figure 1-2).

2. METHODS
This section describes the gage locations, gage installation, field discharge measurement
methods, and the development of the discharge rating curves and discharge calculations
using continuous measurement water level sensors. This section also describes the
methods used to document fish presence / absence longitudinally in HBC. Data were
obtained, managed, and analyzed using scientifically appropriate and widely accepted
and repeatable sampling techniques.
2.1. Gage Site Selection
Stream gaging stations were established in HBC to measure surface water discharge
longitudinally. Stream gaging stations provide the foundation for the collection of
continuous surface water elevation (stage) data that is later converted to a discharge
volume using a rating curve that plots the relationship of surface water stage height to
discharge.
Three surface water gaging stations were established longitudinally in HBC in 2013 to
quantify surface water flows from the headwaters to the lower reaches of the creek. The
longitudinal placement of gaging stations was selected to evaluate the proportional
contribution from catchment areas in a downstream progression. The field location of
each gage was recorded using a global positioning system (GPS). A helicopter field
reconnaissance was performed on April 22, 2013 to determine accessibility and gage site
selection for proper gage installation.
Gage 1 was installed on June 14, 2013 located at a pool tail-out on the West Fork of
Upper HBC at approximately 2,000 feet of elevation. The Gage 1 site was selected to
quantify water yields available for power generation in the Upper HBC in the vicinity of
the proposed diversion. Gage 1 site selection was also influenced by potential avalanche
conditions during the initial installation. Gage 1 was established June 14, 2013 once
significant dangers presented by avalanche conditions subsided. During the initial April
2013 field work, when the Gage 1 location was not accessible due to snow pack, a
temporary surface water discharge location (Field Discharge Measure 1b) in a location
just upstream of the lower canyon section was established. Field Discharge Measure 1b
was intended to serve as a surrogate discharge site until the Gage 1 location was
installed. Discharge measures at Gage 1 in the 2013 water year indicated sufficient
surface water yields for power generation warranting further investigation in 2014.
In 2014, following a year of planning discussions and a better understanding of
diversion dam locations, Gage D-West and Gage D-East were established. Gage D-East
and Gage D-West were installed prior to the engineering team’s site visit and conceptual
design. As a result, the gage locations are a short distance downstream of the proposed
diversion dam locations for D-East Diversion and D-West Diversion. The gages are in
relatively close proximity to the proposed diversion dam locations and are
representative of the available surface water in the area. The Gage 1 site, established in
Hidden Basin Creek Hydrology and Fisheries Report KEA
ERM 10 2/11/2015
2013, was no longer necessary with the establishment of Gage D-East and Gage D-West
and was decommissioned in July of 2014.
Gage D-West was installed on May 16, 2014. This gage station was established at 1,420 ft
elevation on the West Fork of Upper HBC just downstream of the confluence of a south
and east flowing unnamed tributary but downstream of the proposed diversion
location. Initially, at the time of installation, Gage D-West was thought to be the
proposed diversion location, but was since relocated upstream based upon further
engineering study. Gage D-West therefore includes surface water from an additional
tributary that would not be diverted as part of the Upper Hidden Basin Diversion
Project.
Gage D-East was installed on the February 6, 2014 in the East Fork of Upper HBC.
Unseasonably warm weather and the lack of snow cover during the winter of 2014 in
Upper HBC made it possible to conduct field work so early in the season. Upon
investigation of the site at the proposed diversion (~1,500 ft elevation) field hydrologists
determined that the steep stream gradient and difficult access necessitated moving the
gage station downstream. As a result, the stilling well and gage was installed at
approximately 1,200 ft elevation where access and stream gradient was more practicable
for a stream gage. There are no tributaries or additional direct surface water
contributions between the proposed diversion site and where the gage was ultimately
located. As a result, the data gathered in this location accurately estimates the surface
water available for diversion at the D-East Diversion site.
Gage 2 was installed to quantify the amount of surface water delivered from the West
Fork of HBC before the contributions of the Middle and East Forks join the HBC
mainstem. This gage was installed on April 25, 2013. Gage 2 was placed immediately
above the confluence of the West Fork of Upper HBC with two major tributaries (Middle
and East Forks of HBC). The Gage 2 location coincides with USGS No. 15297110 (Hidden
Basin C Nr Mouth near Kodiak AK). The period of record for the USGS gage operation
was March 1, 1983 and January 31, 1984.
Gage 3 was installed on April 25, 2013 to measure surface water discharge at the mid-
point of the mainstem of HBC. Gage 3 was selected because it is the best “choke point”
to measure discharge in the mainstem which for most of its length is a wide,
meandering, braided, alluvial channel. For much of its length from the confluence with
the West, Middle and East Forks to Gage 3, surface water is absent due to downwelling
resulting in disconnected pools interspersed with sections of dry stream channel. Surface
water connects these pools during peak spring run-off conditions and peak flows during
large storm events.
Stilling wells were established at each gage location housing pressure transducers. Gage
sites were selected in locations containing a suitable location to anchor a stilling well
(bedrock cliff walls or large boulders) and offering protection from high flow events.
Hidden Basin Creek Hydrology and Fisheries Report KEA
ERM 11 2/11/2015
2.2. Stream Gage Station Design
Stream gaging stations were established to continuously record surface water elevations
which were then converted to discharge volumes. Each stream gage location contains a
stilling well, a pressure transducer recording water height and an analog staff gage. The
stilling well functions as housing for the pressure transducer (Solinst 3001 LT
Levelogger Edge, M5/F15) data logger that records real-time fluctuations in water
surface elevation (stage) when compensated for atmospheric pressure. Solinst 3001 LT
Barologger Edge (M1.5/F5) sensors were deployed at the Gage 1 and Gage 3 locations in
2013 to allow compensation for real time atmospheric pressure fluctuations at each site.
Two separate barologgers were installed to account for elevation differences
longitudinally in HBC between gaging stations. In February 2014, a third barologger was
installed at D-East coinciding with installation of the stream gaging equipment there.
An analog staff gage was mounted to the outside of the stilling well for redundancy and
to provide hydrologists with a check for adjusting pressure transducer stage height if
necessary. The stilling well was constructed with 2-in galvanized steel pipe or schedule
40 PVC. The pipe or PVC was secured to existing stable features in the stream channel
such as bedrock or large boulders using 3/8 in x 5 in concrete anchor bolts and 1/8 in x 1
in pre-drilled steel hanger strap or a Unistrut system.
The stilling wells were located in areas of the channel that were protected from high
velocities and debris. To the extent possible pressure transducers were installed such
that they would capture data at all flow levels (Photograph 2-1). The analog staff gage
consisted of a 3.33 ft gage plate attached to a suitable backing and anchored to or
adjacent to the pressure transducer housing for analog recording during site visits and
subsequent calibration of the pressure transducer. At Gage 3, a second analog staff gage
(3.33 - 6.67 ft gage plate) was attached to a T-style fence post to record stage heights
exceeding the 3.33 ft gage.
In order to correlate discharge with water level height at each gage station on an
ongoing basis, the elevations of the staff gage and pressure transducer were surveyed
using a Transit level and referenced to two permanent benchmarks established at each
of the gaging sites. Benchmarks were established using either an expandable rock
anchor bolt drilled into the bed rock above the gage location or rebar driven into the
river bank above the high water mark. The initial benchmark was arbitrarily set to
100.00 ft and the elevation of all other survey points were relative to this point. A Kevlar
tape measure was used to establish horizontal stations across cross sections.

2.3. Discharge Measurement
Discharge was measured during each site visit to develop a correlation between surface
water elevation and water volume. Discharge was measured at a representative cross
section, which was defined using a tagline stretched across the active channel
perpendicular to flow. Cross sections were established in a relatively straight portion of
the channel in an area where flow was distributed as uniformly as possible across the
channel. Standard guidelines for cross section selection and placement were followed.
Meander bends were avoided, as were obstructions such as boulders and areas of the
channel that narrowed or widened appreciably.
Discharge at each gage site was measured using the USGS midsection method. The
method is based on protocols developed by the USGS (Buchanan et al. 1969; Rantz et al.
1982; and Nolan et al. 2007). The midsection method divides the stream into a number of
rectangular partial sections across the channel and assumes that the velocity measured
in each partial section represents the mean velocity of that section. The width and depth
of each partial section is multiplied by the average velocity in that section such that a
discharge for each partial section is calculated. The summation of the calculated
discharges for all the individual partial sections is the total discharge for the stream
(Figure 2-1).
Velocity in each partial section was measured using a Marsh-McBirney velocity meter
mounted on a top setting wading rod. The width of the active channel was measured
using a Kevlar tape to define the total cross section width as well as individual partial
Hidden Basin Creek Hydrology and Fisheries Report KEA
ERM 13 2/11/2015
sections. The spacing of the partial sections along the tape was calculated based on the
width of the active channel, and the number of partial sections needed. The USGS
midsection method stipulates that the ideal measurement will have less than five
percent flow in any single partial section, thus the cross section was typically divided
into 25 to 30 partial sections. Flow depth and velocity was measured at stations along
the tape that represent the midpoints of the partial sections using the wading rod and
velocity meter. At each partial section, if water depth was less than or equal to 2.5 ft,
mean velocity of the section was determined using a single velocity measurement at 0.6-
depth below the water surface. If the water depth was greater than 2.5 ft, velocity was
measured at 0.2 and 0.8 of the observed depth below the surface then averaged to
calculate the mean velocity of the subsection. Discharge notes for each of the partial
sections were recorded in the field notebook. Total discharge and other pertinent
parameters were then calculated in an electronic spreadsheet using the field
measurements.
FIGURE 2-1: USGS MID-SECTION METHOD
2.4. Stage-Discharge Rating Curve Development
A rating curve was developed for each gage location to correlate surface water
elevations recorded continuously by the pressure transducer to a discharge volume. The
field discharge measurements collected at each gage station in 2013 and 2014 provided
an instantaneous flow rate and a corresponding staff gage height. Field discharge,
pressure transducer measurements, and staff gage readings were plotted graphically. A
mathematical regression was applied to create a discharge rating of the stage–discharge
relationship. The resulting rating curve formula was specific to each gage location
accounting for the unique channel shape and controls at each site. A regression formula
was calculated for each gage site location. Either a power function or a 2nd order
polynomial was used to establish the rating curve at each of the four gage sites. The use
of either a power function or a 2nd order polynomial was determined by evaluating
which function best fit the data. The function with a correlation coefficient, the R-
Hidden Basin Creek Hydrology and Fisheries Report KEA
ERM 14 2/11/2015
squared value, closest to 1.0 represents the best fit. Rating curves and correlation
coefficients for respective gage locations are provided in Appendix A.
The discharge rating curve function was used to calculate discharge based on stage data
continuously recorded by the pressure transducers housed in the stilling wells. The
stage data downloaded from the pressure transducer was corrected using the barometric
pressure data from the nearest barologger and then multiplied by the rating curve
function to produce a discharge measurement calculation for each data point.
2.5. Catchment Area Size
In order to quantify the proportion of water diverted at the Upper Hidden Basin
Diversion Project relative to downstream locations, particularly the mainstem
downstream of Gage 3, catchment area sizes were calculated using geographic
information system (GIS) tools. The USGS National Hydrography Dataset Watershed
Boundary Dataset, HUC 12 level was used for the HBC watershed. Sub-catchment
drainage areas within HBC watershed were digitized from USGS 63K (1 inch = 1 mile)
topographic map contours provided by the Geographic Information Network of Alaska
(GINA) webmap service.
2.6. Synthesized Hydrographs for Ungaged HBC Catchments
The loss of surface water to subsurface flows at Gage 3 eliminated the ability for
straightforward analysis of the proportion of surface water flow measured at Gage 3
originating in Upper HBC. Furthermore, the loss of surface to subsurface flows at Gage 3
eliminated the ability to quantify the contributions from the Middle Fork and East Forks
of HBC as well as unnamed tributaries relative to the West Fork of HBC. In order to
quantify the contributions of each catchment area to the overall water yield, surface and
subsurface flows, in the mainstem of HBC, hydrographs were synthesized using average
daily discharge data from USGS gages located in HBC. Hydrographs for ungaged
catchments in HBC were synthesized using the drainage-area ratio method (Hirsch
1979) extrapolated from the average daily discharge data at the USGS gages. The
drainage-area method assumes that within a given area, discharge is directly
proportional to drainage area. The accuracy of this method requires that gages be within
a similar or the same hydrologic area, and increases with the redundancy of gages over a
given period. For longitudinal comparison purposes using similar water year
characteristics, hydrographs were synthesized for Gage D-East, Gage D-West, Gage 2
Gage 3, the Middle Fork of HBC and the East Fork of HBC as well as unnamed
tributaries entering the mainstem.
Two USGS gages located in the West Fork of HBC contained discharge data over the
same period of time in the 1980’s from which to construct synthesized hydrographs.
These gages were the USGS No. 15297100 (Hidden Basin C near Port Lions AK) and
USGS No. 15297110 (Hidden Basin C Nr Mouth near Kodiak AK). The period of record
for both gages was between March 1, 1983 and January 31, 1984. This comprises nearly
Hidden Basin Creek Hydrology and Fisheries Report KEA
ERM 15 2/11/2015
an entire year’s worth of data, excluding February. The period of record for USGS No.
1527100 was longer (between August 1, 1982 and January 31, 1984).
Drainage areas for the entire HBC (to its mouth at Hidden Bay) and all sub-catchments
of interest were delineated from topographic layer data (GINA), best data layer web
mapping service Extras, and hill shaded digital raster graphic using GIS.
Two sets of average daily discharge values were calculated for the entire HBC drainage
by applying the drainage-area ratio method to the two USGS gage data sets
independently. These values were then averaged to calculate an average daily discharge
value based on the combined USGS data sets. Further application of the discharge-area
ratio method produced average daily discharge values for each sub-catchment of
interest as respective percentages of the larger HBC basin quantities.
2.7. Fish Presence / Absence in HBC
In 2014, KEA initiated a fish presence / absence study at the established gage locations
as well as Site 1b directly upstream of a large waterfall in the West Fork of HBC. Prior to
this study, little was known about fish distribution in the drainage and habitat available
for various life stages of fish. This initial effort to document fish presence / absence at
respective gage locations combined with aerial flights to document spawning adults
coupled with ground documentation provided insights on fish distribution relative to
the mainstem and West Fork of HBC.
Minnow traps were set at each gage locations in HBC. The objective of the fish trapping
program was to document the presence or absence of fish longitudinally. Wire-mesh
minnow traps have demonstrated effectiveness sampling juvenile salmon in difficult to
access habitat such as deep pools or dense cover (Swales 1987). Adult fish distribution
was documented using aerial flights and observations by foot. The lower 3 miles of
HBC, the mainstem of HBC below Gage 2, is designated an anadromous waterway in
the Catalog of Waters Important for the Spawning, Rearing or Migration of
Anadromous Fishes (Johnson and Coleman 2014) otherwise known as the State of
Alaska Anadromous Waters Catalogue (AWC). This reach is listed as supporting chum
and pink salmon, as well as Dolly Varden.
Passive capture techniques such as minnow trapping are appropriate methods for
detecting the presence or absence of fish (Royle and Nichols 2003) when used during a
time of year when fish species and specific life stages are most likely to be present in the
area sampled. Minnow trapping can provide reasonable indices of change in stock
abundance over time when they are fished in a similar manner, location, and time of
year (Hubert 1996).
Minnow traps were used for the capture and collection of fish at respective gage
locations under Alaska Department of Fish and Game (ADFG) Fish Resource Permit
#SF2014-153 received on April 3, 2014. Traps were placed in areas considered to be good
juvenile salmonid habitat: areas with a relatively low velocity and ample cover if
Hidden Basin Creek Hydrology and Fisheries Report KEA
ERM 16 2/11/2015
available. In complex habitats (e.g. frequent cover opportunities, many side channels,
etc.) traps were set more closely, while more homogeneous habitats required greater
spacing between traps.
Galvanized minnow traps with 0.32 centimeter (cm) size mesh and two 1.90 cm funnel
openings were baited with salmon roe. Overall trap dimension was 44 cm length by 23
cm width. All traps were set such that at least one entry funnel was fully submerged.
Approximately two ounces of betadine-cured salmon roe was placed in a nylon stocking
and suspended from the middle of each trap. The traps were set for approximately 24
hours.
A total of 15 traps were deployed during each trapping event in May, July, August, and
October. Three minnow traps were placed at each of the four stream gage locations. A
fifth minnow trapping site was located upstream of a large waterfall (Waterfall A)
thought to act as an upstream fish migration barrier. This site corresponds to the
location of field discharge measurements at Site 1b in Upper HBC in the shallower
gradient meadow area. Photograph 2-2 illustrates a typical minnow trap set at the
margin of the creek, under overhanging cover, and in an area of low stream velocity.
The three minnow traps per gage were placed directly upstream or downstream of the
respective stream gage location in suitable stream habitat for juvenile fish. Traps were
labeled according to gage location and location relative to one another. Gage and
locations were abbreviated as follows: G3 = Gage 3; G2 = Gage 2; 1b = Site 1b; DE =
Gage D-East; DW = Gage D-West. The stream gage number was followed by a number
from one to three with the furthest downstream trap receiving the lowest number. For
example, Trap DW-2 was set at Gage D-West and located between DW-1 and DW-3 in
the stream channel. After traps were set they were photographed and their GPS
locations were recorded.
All living organisms collected in the traps were transferred to a five-gallon bucket filled
with freshwater. Fish were placed in a separate three-gallon bucket containing a 25
mg/L clove oil solution to anesthetize them for accurate measurements and
identification. Fish were identified to species (except for sculpin), measured to the
nearest millimeter (mm) total length, weighed to the nearest 0.1 gram (g), and
photographed. After identification and measurement were completed, the fish were
placed in a five-gallon bucket of freshwater until they resumed active behavior, then
were returned to the stream location from which they were collected. All data was
recorded in “Rite in the Rain” notebooks. Throughout the course of this study no fish
specimens were retained for identification and no fish mortality occurred.

3. RESULTS
This section describes the field work completed in 2013 and 2014 including field
discharge measurements and fish presence / absence and data analysis necessary for
developing site specific hydrographs including rating curves for Gage D-West, Gage D-
East, and Gages 2 and 3 as well as calculating water yield for the Upper Hidden Basin
Diversion Project.
3.1. Stage-Discharge Relationship
Table 3-1 presents a summary of installation dates and field discharge measurements for
each gage station in the HBC watershed in 2013 and 2014. The data described in this
section was used to develop the stage-discharge rating curve applicable for each stream
gage. The rating curves (Appendix A) were then used to build the hydrographs for each
location based on water levels continuously recorded by pressure transducers at each
stream gage location. Each gage locations as well as the watershed characteristics are
documented in photographs contained in Appendix B.
Gage 1 3.1.1.
Surface water discharge at Gage 1 was measured four times in 2013 and once in 2014
prior to decommissioning. Measured discharge ranged from a low of 12.6 cfs in July
2014 to a high of 54.8 cfs in June 2013. Indicative of the flashy nature of the drainages on
Kodiak Island, discharge measured on October 3, 2013 (50.4 cfs) was over three times the
discharge measured the following day (15.4 cfs). Discharge measured on October 3, 2013
was associated with 1.84 in of rain recorded at the National Weather Service Station in
Kodiak (PADQ).
Gage D-West 3.1.2.
Surface water discharge at Gage D-West was measured during four site visits in 2014;
May, July, August and October. In total, 9 field discharge measurements were made
ranging from a low of 3.4 cfs in October to a high of 90.7 cfs in May. All flow
measurements were taken from the same cross section of the stream channel to ensure
correlation between visits. Gage D-West is located in a stream reach dominated by large
boulder substrate and stable bank configuration.
Gage D-East 3.1.3.
Surface water discharge was measured at Gage D-East during five site visits in 2014;
February, May, July, August and October. In total, 10 field discharge measurements
were made at D-East resulting in surface water discharges ranging from a low of 1.3 cfs
measured in October to a high of 37.2 cfs measured in May. All flow measurements were
taken from the same stream channel cross section to ensure correlation between visits.
Hidden Basin Creek Hydrology and Fisheries Report KEA
ERM 19 2/11/2015
Gage 2 3.1.4.
Surface water discharge was measured three times in 2013 at Gage 2, ranging from a low
of 16.6 cfs on April 23, 2013 to a high of 78.4 cfs on July 24, 2013. In 2014, discharge was
measured nine times ranging from a low of 9.1 cfs measured on October 7, 2014 to a high
of 104.3 cfs measured on July 14, 2014. High flows on May 17, 2014 prevented safe
measurement of discharge at this location.
High flow events in 2013 destroyed Gage 2 in mid-August of that year. Substantial
bedload movement leading to changes in channel geometry occurred between the
August 2013 and October 2013 site visits at Gage 2. Gage 2 was re-installed May 17,
2014. Surveys of the channel cross section illustrate the change in channel shape from
April 2013 to July 2014 (Figure 3-1). In 2014, the channel was one ft deeper compared to
April 2013. Because of the high flow event destroying Gage 2, continuous discharge data
was not recorded for this location from July 24, 2013 to May 17, 2014. In order to perform
longitudinal comparisons between gage locations, discharge data from the USGS gage
No. 15297110 adjacent to the Gage 2 location was used in the hydrology analysis using
synthesized hydrographs.
FIGURE 3-1: GAGE 2 CHANNEL CROSS SECTION COMPARISONS, 2013 AND 2014.
Gage 3 3.1.5.
In 2013, Gage 3 discharge was measured four times ranging from a low of 1.1 cfs on
April 25, 2013 to a high of 478.2 on June 15, 2013. In 2014, Gage 3 discharge was
measured six times ranging from a low of 13.1 cfs on August 28 to 447.9 cfs on May 18,
2014. The only flows present at Gage 3 during the October 2014 site visit were from a

small tributary drainage entering the main channel on the river right bank
approximately 250 ft upstream of the gaging location and were estimated at 0.1 cfs. The
mainstem of HBC upstream of Gage 3 was dry during this October 2014 site visit.
During the October 2013 site visit, it became apparent that the channel geometry had
changed substantially at Gage 3, likely the result of the same high flow events in August
2013 that destroyed Gage 2. Figure 3-2 documents the channel bed changes between
April 2013 and August 2014. As a result of the change in channel geometry, the rating
curve at Gage 3 used for calculating surface water discharge from the pressure
transducer stage recordings was valid through August 05, 2013 only. A new rating curve
was developed in 2014 after additional surveys of the channel geometry along with
discharge and corresponding stage height measurements in 2014.
Gage 3 was winterized in October 2013. The pressure transducer data recorded between
October 2013 and May 2014 was not considered accurate due to changes in the channel
geometry altering the stage - discharge relationship. As a result, the data for that time
period was not used in this report. There were several significant weather systems over
the period of months between October 2013 and May 2014. One particular system
dropped 6.64 in of rain over the course of five days in January. Events like these, besides
having an impact on channel geometry and surface water controls, mobilize fine
material in the stream that settles inside the stilling well and around the pressure
transducer. As a result, stage readings can be falsely elevated and return unrealistic
discharge volumes when calculated with the discharge rating curve. These false
readings were removed during data review process.
The mainstem of HBC contains a dynamic stream channel that changes shape and
location during large precipitation events that mobilize the alluvial bedload. The
downwelling of surface water to subsurface flows in this reach further increases the
difficulty of measuring the total contributions from upper HBC. The regularly shifting
channel shape in the mainstem reach makes maintaining a relevant stage–discharge
relationship throughout the year challenging.

3.2. Catchment Area Size Comparisons
Drainage area size was calculated for each gage location as well as ungaged catchments
(Table 3-2). For comparison purposes, the catchment area size was also expressed as a
percentage relative to the size of the entire HBC drainage. Gage 1 was located at 2,000 ft
in the mainstem of West Fork of Upper HBC and has a catchment area of 1.29 mi2 or
5.2% of the total catchment of HBC (Figure 3-3).
Gage D-East is located at 1,200 ft elevation in the upper reaches of the valley on a
tributary to the West Fork of Upper HBC and has a catchment area of 1.26 mi2 or 5.1% of
the total catchment of HBC. Gage D-West is located at 1,420 ft elevation at the initially
chosen site for the proposed diversion dam location on the main reach of the West Fork
of Upper HBC and has a catchment area of 3.42 mi2 or 13.8% of the total catchment of
HBC. The drainage area of Gage D-West and Gage D-East combined is 4.69 mi2
comprising 18.9% of the total area of HBC.
The D-East and D-West Diversions are located upstream of the respective stream gages
at D-East and D-West. The respective diversion locations were located upstream after
the initial engineering analysis and survey determined it was necessary to relocate
upstream to higher elevations to provide the proper grade for delivering water to Terror
Lake. As a result, the total catchment area of the proposed diversion project is 3.82 mi2 or
15.4% of the total area of HBC.
Hidden Basin Creek Hydrology and Fisheries Report KEA
ERM 24 2/11/2015
Gage 2 is located at 200 ft elevation at the mouth of the lower canyon upstream from the
confluence with the Middle and East Forks of HBC. Gage 2 catchment area is 11.76 mi2
or 43.7% of the total catchment of HBC. Gage 2 captures three times more area than the
proposed diversion project.
Gage 3 is located at approximately 100 ft elevation 1.5 mi from the mouth of the creek
where it discharges into Hidden Basin. The catchment area at Gage 3 location is 21.70
mi2 or 87.3% of HBC. Gage 3 captures 5.7 times more area than the proposed diversion
project.
Upstream of Gage 3 and downstream of Gage 2 two additional major tributaries (Middle
Fork and East Fork) converge with the West Fork of HBC. The Middle Fork has a
drainage area of 4.63 mi2. The East Fork has a drainage area of 2.17 mi2. Together these
tributaries comprise 27.3% of the total drainage area of HBC.

3.3. Hidden Basin Creek Hydrology
The hydrology in HBC is characterized by a spring snowmelt hydrograph overlaid by
flashy, short duration high flow events associated with heavy precipitation events
throughout the year. This is evident on the hydrographs as steep spikes with very little
ascending or descending lag time prior to or after the peak flow. Persistent rain
throughout the year saturates the soil and underdeveloped flood plains through much
of the basin resulting in an abrupt increase in the surface water discharge shortly
following precipitation events. During the early spring months it is not uncommon to
receive heavy rain on a deep snow pack, accelerating the rate of snow melt with latent
heat of precipitation. Monthly mean, maximum, and minimum flow statistics for gaged
sites are presented in Table 3-3. This table illustrates the differences between the
discharge observed in the upper reaches relative to the mainstem of HBC. Maximum
flows recorded per month provide a foundation for size of the water conveyance pipe.
Representative hydrographs for HBC are included in this section. Hydrographs were
plotted for respective years of data collection and displayed on a generic water year axis
(October 1 through September 30) for comparison between years.
2013 and 2014 Discharge 3.3.1.
Surface water discharge in HBC was reported for the D-West Diversion, Gage D-West
and Gage D-East (Figure 3-4) by water year. Gage 1 discharge measured from June 14,
2013 – May 15, 2014 was extrapolated based on catchment area size ratios to the D-West
Diversion to illustrate the quantity of water available for power generation. Gage D-
West was installed on May 16, 2014. Discharge data collected at Gage D-West from May
16, 2014 to October 8, 2014 was extrapolated to the catchment area of D-West Diversion
Gage D-East data was determined to be representative of surface water conditions at the
D-East Diversion since no tributaries enter this reach between the proposed diversion
and Gage D-East.
Peak discharge events coincide with large precipitation events that elevate the stage of
the water in the creek. During much of the year, maximum monthly peak flow in HBC
for respective locations exceeds the minimum monthly flow by two to three orders of
magnitude (Table 3-3). These peak flow events contribute substantially to the mean
monthly water yield. Local precipitation data for 2014 was obtained from the National
Weather Service (NWS).
At the D-West Diversion location, the peak flow in 2013 was recorded on August 6th at
862.9 cfs. This peak flow at D-West Diversion was based on discharge data recorded at
Gage 1 extrapolated to the D-West Diversion location. The peak flow coincided with 1.72
in of rain recorded at PADQ. In 2014, the D-West Diversion peak flow was 1,285.7 cfs
recorded on January 17, 2014. Again, this peak flow was based on

discharge data recorded at Gage 1 and extrapolated downstream to the D-West
Diversion. This January peak flow event coincided with a heavy precipitation event and
warmer air mass. The NWS PADQ Station for January 2014 recorded 6°F warmer than
normal temperatures for the month compared to the statistical records and received over
six in more rain than average. On January 16th and 17th the PADQ station recorded 4.58
in of precipitation.
Gage D-West began recording discharge on May 16, 2014. Discharge data for this
analysis runs through October 7, 2014. The peak flow at Gage D-West from May 16, 2014
through October 07, 2014 was 458.3 cfs recorded on September 14 coinciding with 1.99 in
of precipitation at PADQ.
Gage D-East was installed on February 6, 2014. Discharge data for this analysis runs
from the date of installation through October 7, 2014. The peak flow at Gage D-East was
191.6 cfs on June 6, 2014 coinciding with 2.98 in of precipitation at PADQ.
The D-East and D-West gages did not peak on the same date in 2014. The D-East Gage is
located in a steeper and tighter drainage with more northerly aspects compared to D-
West Gage. This may have delayed snow melt in May. The rain on June 6th likely
combined with snowmelt resulting in the peak discharge for the D-East Gage for 2014.
There was a corresponding peak on the D-West Gage hydrograph on June 6, 2014 but it
was not the peak discharge for that location in 2014.
Surface water discharge for the West Fork and the mainstem of HBC was reported using
data collected at Gage 2 and Gage 3 (Figure 3-5) by water year. The data collected at
these locations is incomplete due to peak flow events damaging equipment and altering
the channel shape. Gage 2 was forcibly removed from the bedrock wall it was attached
to by high flows and bedload movement sometime between the July and October 2013
site visits. The gage station was re-established at an adjacent location May 17, 2014. At
Gage 3, changes in the channel shape due to bedload movement during a peak flow
event in August 2013 altered the stage-discharge relationship requiring a new rating
curve to calculate discharge. Similar flow events over the winter of 2013/2014 between
site visits to Gage 3 continued to alter the stage – discharge rating curve. The rating
curve was re-established during the May 2014 site visit. Despite the limited data set, the
hydrograph for Gages 2 and 3 illustrates the large discharge fluctuations in 2013 and
2014 in the lower reaches of HBC. The hydrograph also illustrates that during base flow
conditions in HBC, surface water discharge at Gage 2 often exceeds discharge at Gage 3
confirming the downwelling of water to the subsurface that occurs between these gages
in the mainstem.
Peak flows at Gage 2 for the period of data collection occurred on September 14, 2014
when NWS recorded 1.99 in of precipitation at PADQ. The peak flow at Gage 2 on
September 14, 2014 was 1,150 cfs.
The peak discharge measured at Gage 3 between May 18, 2014 and October 7, 2014 was
13,347 cfs in September 2014 coinciding with the precipitation event of 1.99 in.

ERM 29 2/11/2015
Gage 3 surface water volumes did not increase in a linear pattern relative to longitudinal
flow comparisons between upstream gages; Gage D-East, Gage D-West and Gage 2. This
is likely due to the fact that surface water flows in the mainstem reach of HBC go below
to the subsurface causing the stream channel to dry up between Gage 2 and Gage 3. The
subsurface flows partially resurface at a point just upstream of Gage 3, but substantial
portions of the mainstem of HBC upstream of Gage 3 remain disconnected with
fragmented pools of surface water. In fact, during base flow conditions observed in
April 2013, the mainstem of HBC was dry for substantial lengths upstream of Gage 3
despite a discharge of 41.5 cfs measured at Gage 2 on the same day. Similarly, in July
2013 during moderate flow conditions at Gage 2, the mainstem channel between Gage 2
and Gage 3 was dry in places indicating subsurface flow. During base flow conditions
observed in October 2013, the mainstem of HBC was dry, with the exception of isolated
standing pools upstream and downstream of Gage 3 despite a discharge of 9.1 cfs
measured at Gage 2 on the same day. Similarly, on July 14, 2014 during moderate flow
conditions at Gage 2 (discharge of 104.3 cfs), the primary channel between Gage 2 and
Gage 3 was dry in places indicating subsurface flow. Discharge measured at Gage 3 on
the same day was 86 cfs.
Due to the subsurface flows in the mainstem channel coupled with contributions from
ungaged tributaries downstream of Gage 2, the discharge proportion contributed
directly from the Upper Hidden Basin Diversion Project to the Gage 3 location in the
anadromous reach cannot be calculated based on surface water discharge measures
alone. Accurate quantification of the proportion of surface water derived from the
combined the Upper Hidden Basin Diversion Project relative to Gage 3 would require
additional surface water gages located on the Middle and East Forks of HBC as well as
unnamed tributaries combined with an exhaustive network of groundwater wells and
geologic analysis of alluvial deposition to obtain a cumulative volume (surface and
subsurface) at Gage 3. Even with this level of effort there would still be a high degree of
uncertainty in the total volume of water (surface and sub-surface).
Alternatively, analyzing water yields for respective catchments based on drainage area
size regardless of flow pathways in the mainstem quantifies the proportion of the water
withdrawal from the Upper Hidden Basin Diversion Project relative to specific locations
downstream in HBC. The water yield analysis can be combined with knowledge of fish
distribution and fish habitat in the mainstem of HBC to assess potential project impacts
downstream.

Comparison with USGS Discharge for Upper Hidden Basin Creek 3.3.2.
The discharge data collected in Upper HBC in 2013 and 2014 was compared to historical
data collected by the USGS in HBC as part of the data validation process and to include
all available hydrology data for this report.
The USGS installed and maintained two surface water gaging stations on the West Fork
of Upper HBC between 1982 and 1984. The upstream station referred to as USGS
15297100 was located just downstream of the proposed D-West Diversion and
approximately 300 linear ft upstream of Gage D-West. The downstream station referred
to as USGS 15297110 was located at the mouth of the lower canyon on the West Fork of
HBC approximately 200 feet downstream of Gage 2 (2013) location and 20 ft
downstream of the current location of Gage 2. The 1983 data set represents the only full
year of data collection for Gage 2.
The USGS 15297100 data collected from 1982–1984 was compared to the discharge data
collected at Gage 1 and Gage D-West (Figure 3-6). Surface water discharge collected at
Gage 1 and Gage D-West was extrapolated downstream and upstream, respectively, to
the USGS 15297100 location using the drainage area proportion of the watershed and
normalizing data sets to a generic water year (October 1 through September 30). The
magnitude, frequency, and duration of extrapolated surface water discharge data from
Gage 1 and Gage D-West respectively are comparable to discharge measures recorded at
USGS 15297100. The peak flows and elevated winter discharge observed for the Gage 1
(WY 2014) data is likely due to the 6°F above average winter air temperatures coupled
with heavy precipitation events. The lower discharge during the mid-summer period in
2014 is likely due to the lack of mountain snowpack during the 2014 water year
(personal observation and conversations).
Synthesized Hydrographs for Ungaged Catchments 3.3.3.
Mean daily discharge for USGS Gage 15297100 and 15297110 was used to synthesize
hydrographs for ungaged catchments in HBC, as well as to compare gaged locations
with discontinuous discharge data sets. Figure 3-7 illustrates a longitudinal hydrograph
for the combined D-East and D-West Diversion, Gage 2, Gage 3, and the mouth of HBC
at Hidden Basin. The hydrograph demonstrates the proportional increase in daily mean
discharge as catchment area increases in a longitudinal fashion downstream assuming
no water is lost to subsurface flow. Surface water discharge in the synthesized
hydrograph is typically 2.5 times greater at Gage 2 compared to Gage D-East and the D-
West Diversion (Table 3-4). Likewise, the synthesized surface water discharge at Gage 3
is nearly 2 times greater than Gage 2 throughout the year. Annual maximum flows for
respective gage locations are lower in the data synthesized from the USGS data
compared to surface water discharge measured in 2013 through 2014 due, in part, to the
fact that the USGS data was daily mean flows as opposed to continuous recording
discharge. This could also be a reflection of inter annual variation in precipitation
between water years.

and D-West Diversion locations. Data collected for the D-West Diversion covers the
period from June 14, 2013 through October 8, 2014. For Gage D-East, data was
extrapolated from the Gage 1 data collected from June 14, 2013 - February 6, 2014. After
February 6, 2014, discharge data measured directly at Gage D-East was used for the
calculations through October 8, 2014.
A full year of discharge was measured in WY 2014. The total amount of water available
for diversion into Terror Lake in WY 2014 was 29,585 ac ft (Table 3-5). The total amount
of water available for diversion to Terror Lake during the partial year of measurement in
WY 2013 was 19,954 ac ft.
Generally, the contribution from the larger catchment area at D-West Diversion exceeds
the contribution from D-East Diversion by a factor ranging between two and three
depending on the month. For WY 2014, D-East Diversion comprises 28% of the total
water available for diversion to Terror Lake. D-West Diversion provides the remaining
72% in WY 2014.

This section summarizes the results of the fish presence / absence observations made
during site visits. Juvenile fish presence / absence was documented using triplicate
minnow traps at four gage locations plus an intermediate field discharge location above
a perceived fish migration barrier in 2014. Adult fish distribution was documented using
helicopter flights combined with documentation on the ground. Anadromous spawners
were observed in the mainstem of HBC as far as Gage 3, but were not found upstream of
that point due to the dry stream bed between Gage 3 and Gage 2. Juvenile anadromous
fish were collected as far upstream as Gage 2 in the West Fork of HBC. Resident Dolly

Varden (Salvelinus malma) were collected in the West Fork of HBC upstream of an
approximate 50 ft waterfall (Waterfall A) in a low gradient reach. No fish were collected
or observed upstream of a second waterfall (Waterfall B) at Gage D-West or Gage D-East
adjacent to the proposed diversion locations.
The mainstem of HBC below Gage 2 is designated an anadromous waterway in the
AWC. HBC is listed as supporting chum salmon (Oncorhynchus keta) as present in the
drainage and spawns in the drainage, pink salmon (Oncorhynchus gorbuscha) as present
in the drainage and spawns in the drainage, and Dolly Varden as present in the
drainage. The AWC terminates the upstream boundary for anadromous fish distribution
at the upstream end of the mainstem, the confluence with the West Fork, Middle Fork,
and East Forks of HBC. In 2014, minnow trapping efforts associated with this study
confirmed juvenile and adult coho salmon (Oncorhynchus kisutch) were present in the
mainstem of HBC. Coho were not previously listed in the AWC for the mainstem of
HBC. The results from these fish collection efforts have been presented to ADFG so the
AWC can be updated to include coho.
The fish presence / absence minnow trapping sites were selected to document fish
distribution longitudinally in HBC relative to stream gradients and potential fish
barriers (Figure 3-8). Upper HBC is a high gradient stream confined by narrow valley
walls and dropping approximately 2,500 ft before reaching the mainstem of HBC.
Upper HBC contains multiple cascades and two noteworthy waterfalls that present
potential barriers to upstream fish passage, Waterfall A and Waterfall B. Photos
documenting both waterfalls are labeled in Appendix B. Waterfall A is located
approximately 0.5 mi upstream from the confluence of the West Fork of HBC with the
mainstem of HBC and is approximately 50 ft in height. Waterfall B is located at the
confluence of the Upper East Fork and Upper West Fork of Upper HBC. As noted,
resident Dolly Varden were collected upstream of the first waterfall, Waterfall A, but
were not collected above the second waterfall, Waterfall B, despite four sampling trips
spread over the spring, summer and fall of 2014. The Dolly Varden above Waterfall A
were only collected on two of the four sampling efforts in low numbers; 3 Dolly Varden
total. The results of each minnow trapping field effort are described below for each site.
Appendix C includes the minnow trapping data and Appendix D contains selected
photographs of fish species collected.
In May 2014, minnow traps were set on the 18th and retrieved on the 19th. Soak times
ranged from a maximum duration of 22 hours 57 minutes at trap 1b-3 to the shortest
duration of 15 hours 15 minutes at trap DW-3. A total of five fish were collected in four
different traps: four Dolly Varden and one sculpin (Cottus sp.) (Photo D-1). All of the
fish collected were trapped adjacent to Gages 2 and 3. Minnow traps were set in May at
the three sample sites upstream of Gage 2 (Site 1b, Gage D-West and Gage D-East), but
no fish were collected or observed at these three sample sites (Appendix C.1).
In July 2014, minnow traps were set on the 15th and retrieved on the 16th. Soak times
ranged from 18 hours 40 minutes at DW-1 to 22 hours 49 minutes at G3-1 (Table C.2). A

total of 19 fish, all Dolly Varden, were collected in six different traps. Three of the Dolly
Varden were trapped at Gage 3, 14 were trapped at Gage 2 and two of the Dolly Varden
were caught at Site 1b located upstream of Waterfall A. No fish were collected at the D-
West or D-East Sites in July.
Surface water flow between Gage 2 and Gage 3 was continuous on July 14, 2014
although very shallow in places. On July 15th, the channel between Gage 2 and Gage 3
had gone dry in places resulting in isolated pools and runs with dry stream channel
between.
In August 2014, minnow traps were set on the 29th and retrieved on the 30th. Soak times
ranged from a maximum duration of 23 hours 37 minutes at 1b-3 to 21 hours 49 minutes
at G3-3 (Table C.3). A total of 59 fish were collected from seven different traps including
17 coho salmon and 42 Dolly Varden (Photo D-4). The majority of the fish caught in
minnow traps, 58, were collected in traps at Gage 2 and G age 3. A single Dolly Varden
was captured at Site 1b upstream of Waterfall A. No fish were collected at Gage D-West
or Gage D-East in August.
Surface water in the mainstem HBC was not continuously connected during the August
site visit. The stream channel was dry at a similar location observed during the July
event between Gage 2 and Gage 3. The initial mile of HBC from the marine environment
contained a substantial number of spawning adult salmon. Upon further investigation
the spawning fish were identified as a combined run of pink and chum salmon (Photo
D-5). None of these fish were able to make it above Gage 3 due to the dry channel bed
upstream.
In October 2014, minnow traps were set on the 7th and retrieved on the 8th. Soak times
ranged from a maximum duration of 22 hours 29 minutes at the D-West sites to 20 hours
3 minutes at G2-3 (Table C.4). A total of 105 fish were collected from six different traps
located at Gage 2 and Gage 3. Of the 105 fish, 39 were identified as coho salmon and the
remaining 66 were Dolly Varden. The most productive trap was located at G3-2 in the
mainstem reach of HBC which caught 33 fish. No fish were collected at Site 1b, Gage D-
West, or Gage D-East in October.
Most of the mainstem reach of HBC in October between Gage 2 and Gage 3 was dry
with the exception of isolated pools, including two pools located near Gage 3. One
isolated pool in particular contained an estimated 30–40 adult coho salmon and several

adult Dolly Varden (Photo D-6). On October 7, 2014, the pool was filled with live fish.
Upon return on the October 8, 2014, 13 dead coho salmon were observed and the pool
size had decreased substantially causing crowding for the remaining fish.
Based on field observations, it appears that juvenile fish use the mainstem reach of HBC
as rearing habitat, finding refuge at creek margins, in pools and areas of low velocity.
During periods of high flow or sufficient water depth adult spawning fish migrate
upstream at least to the location of Gage 3, but infrequently if at all upstream as far as
Gage 2. No adult fish were observed further more than 200 ft upstream of Gage 3. Adult
and juvenile fish become stranded in isolated pools when surface water flow decreases
in the mainstem of HBC largely due to downwelling in the porous alluvial materials
present between Gage 2 and Gage 3. These pools, if deep enough, provide fragmented
overwintering habitat for juvenile fish.
The reaches of HBC above Gage 2 contain marginal quality fish habitat due to the high
gradient, lack of gravel substrate and limited cover. These reaches are fishless aside from
a small resident population of Dolly Varden. The Dolly Varden collected at Site 1b likely
colonized the reach during a period when sea levels were high enough to inundate the
upstream fish barrier presented at Waterfall A. The resident Dolly Varden at Site 1b
apparently adapted to the marginal habitat and are able to withstand being washed
downstream during high water events. Site 1b provides the shallowest gradient
available in Upper HBC which is predominantly comprised of steep riffles, plunge
pools, cascades and waterfalls.
The stunted adult Dolly Varden collected at Site 1b coupled with the depressed
population indicates a lack of genetic exchange with populations located in the
mainstem of HBC. As a result, Waterfall A likely serves as an upstream migration
barrier for Dolly Varden located in the mainstem of HBC. No fish were captured or
observed upstream of Waterfall B downstream from Gage D-West and Gage D-East
suggesting Waterfall B continues to present a barrier to upstream fish passage.
It is well documented that Dolly Varden exist in two forms – anadromous and resident
(Jonsson and Jonsson 1993). In some cases the resident form is found upstream of a
natural barrier that prevents upstream movement of the anadromous form (Ihlenfeldt
2005). Resident forms are not always isolated, however, and their distribution may
overlap that of the anadromous form found downstream. Upstream passage barriers
may result in isolated populations of resident forms. Limited movement longitudinally
may be related to a combination of gradient and discharge combined with physical
barriers in Upper HBC. In an unpublished Forest Service Study of fish movement,
including Dolly Varden, in relation to stream stage it was discovered that few fish move
at very low stream stages (Bryant and Luckey 2004). Other results suggested that
movement of Dolly Varden (< 170 mm in fork length) decreased substantially as stream
stage increases beyond 1.0 ft and ceases altogether above 2.0 ft (Bryant and Luckey
2004).
Hidden Basin Creek Hydrology and Fisheries Report KEA
ERM 42 2/11/2015
Resident Dolly Varden prefer spawning areas at the edges of pools in low velocity water
with a gravel substrate of 1-4 cm (Ihlenfeldt 2005). Cover (large woody debris, rocks),
overwintering areas and low-velocity areas are all important factors to the survival of a
resident Dolly Varden population (Ihlenfeldt 2005). It appears these conditions are met,
at least marginally, by the stream reaches upstream of Gage 2. If the proposed Upper
Hidden Basin Diversions are built it may improve Dolly Varden habitat above Waterfall
A by ameliorating the impacts of high flow and high stream velocity during flood
events. Instream flows downstream of the proposed diversions will be derived from
tributary inputs directly downstream of D-West Diversion continuing to increase
longitudinally downstream at Sites 1b and Gage 2. Figure 3-9 illustrates the volume of
water diverted at D-West and D-East as well as the tributary flow contributions directly
downstream from the D-West diversion. In addition, peak flows in excess of the tunnel
diversion capacity (~900 cfs) will be passed over the diversion structures into the section
of Upper HBC downstream. Additional tributary inputs downstream of the diversions
will contribute peak flows as well.
Anadromous species have distinct life history stages (Figure 3-10) triggered by
environmental cues such as discharge, water temperature and photoperiod (Bjornn and
Reiser 1991). A summary of the life history requirements for coho and Dolly Varden is
provided below.
Coho salmon
Coho salmon are a newly documented anadromous species to the AWC for HBC. The
freshwater and overwinter habitat of juvenile coho salmon have been studied
extensively (Ruggles 1966; Bustard and Narver 1975; Sandercock 1991; Ebersole et al.
2006; Giannico and Healey 1998; others). Juvenile coho salmon thrive in slow water, pool
type habitat where they experience higher growth rates. Large body size confers a
competitive advantage over smaller, slow growing conspecifics in the pursuit of food,
and decreases predation by gape limited predators (i.e. Dolly Varden). Larger juvenile
coho salmon are also better able to maintain their longitudinal position in streams and
rivers than are smaller juvenile coho salmon that are vulnerable to downstream
displacement due to floods (Giannico and Healey 1998) and competition for prime
feeding areas (Ruggles 1966). The presence of pools and other low velocity meso-scale
habitats have been demonstrated to increase freshwater residence time (Ruggles 1966),
which increases individual size at the time of smolt emigration, and improves ocean
survival (Ebersole et al. 2006).
Coho salmon were captured in August and October in HBC in 2014. Juvenile coho
salmon have a longer freshwater residency time (1 to 3 years) than either of the other
two salmon species present in the mainstem of HBC (pink salmon and chum salmon).
Pink and chum salmon fry begin to emigrate immediately downstream upon emergence.
Based on their size at capture, two age groups of juvenile coho salmon were present in
HBC in 2014: age zero, young-of year (YOY) coho salmon and age one coho salmon (fry
that emerged in 2013). Juvenile coho salmon exhibit demersal ‘hiding’ behavior and are

capable of concealing themselves completely within stream substrate (Swales et al. 1986;
Bustard 1986). They have also been documented to undertake both upstream and
downstream migrations to and from overwinter and / or refuge habitat as juvenile pre-
smolts. The fact that coho salmon were not captured in either the May or July sampling
events suggests that the YOY size class had not yet emerged from the gravel or were too
small at that stage to be captured, and that the age 1 size class had not yet moved
upstream into the portions of HBC where minnow traps were set at Gage 2 and Gage 3.
Age 1 coho salmon either wintered at the mouth of HBC or in the unnamed tributary
drainages entering the mainstem of HBC.

Dolly Varden
The waterfall above Gage 2 (Waterfall A) has a major influence on fish distribution in
Upper HBC. The 2014 minnow trapping efforts confirmed the existence of what is likely
a small, isolated population of Dolly Varden. Resident Dolly Varden have distinct life
stages triggered by environmental cues such as discharge (Figure 3-11). The resident
form of Dolly Varden are well known to persist in waters above barriers similar to that
observed in the West Fork of HBC. Throughout their range, Dolly Varden are often the
only species present above fish migration barriers and likely benefit from the absence of
competition for resources. The characteristics of the isolated populations include:

The degree of genetic isolation of this sub- population of Dolly Varden from resident
and anadromous forms below the falls is not known and would require genetic testing
to identify. It is conceivable that some fish located above the barrier falls migrate
downstream leading to some mixing between the two populations in the mainstem of
HBC (Bryant and Lukey 2004) but genetic exchange does not appear possible in an
upstream direction. It has been suggested that the low number of eggs per female Dolly
Varden in isolated populations naturally limits population size in these space and
resource-restricted habitats (Blackett 1973).
Dolly Varden in Alaska are typified by anadromous and resident forms. The
anadromous forms overwinter in streams connected to lakes or in some cases
overwinter in the ocean (Armstrong and Morrow 1980; Bernard et al. 1995). Using the
pattern exhibited in the southern portion of their range in Alaska as a guide (Armstrong
and Morrow 1980; Bernard et al. 1995), it is likely that anadromous Dolly Varden inhabit

the mainstem reaches of HBC during the salmon spawning seasons to feed on salmon
eggs. Salmon eggs are likely a major food source for Dolly Varden in the mainstem HBC,
judging from the high density of pink salmon and chum salmon spawning activity
observed downstream of Gage 3. This food source is not available to the resident Dolly
Varden population above the barrier hence the small size of fish captured there. Due to
the richness of salmon eggs as a Dolly Varden food source, a portion of the mainstem
HBC Dolly Varden population may remain as year-round residents and avoid
anadromy altogether. There is an ecologically driven trade-off between the divergent life
history patterns (Jonnson and Jonnson 1993) related to delaying maturity to maximize
reproductive fitness (anadromous form) or maturing early and reproducing to avoid
high ocean mortality (resident form).

4. DISCUSSION
Diversion of water in Upper HBC is not likely to have an impact on surface water in the mainstem of
HBC downstream. The Upper Hidden Basin Diversion Project comprises only 15 percent of the overall
HBC watershed area. The majority of the flow delivered from the West Fork of HBC manifests as
subsurface flows in the mainstem. In addition, fish distribution in the mainstem of HBC is limited
spatially and temporally by the lack of surface water continuity.
Surface water discharge was monitored longitudinally in HBC in 2013 and 2014 using continuous
recording pressure transducers combined with periodic site visits to measure discharge. The USGS
installed and maintained two surface water gaging stations on the West Fork of HBC between 1982 and
1984. The USGS 15297100 data collected from 1982–1984 was compared to the discharge data collected
at Gage 1 and Gage D-West in 2013 and 2014. The magnitude, frequency and duration of surface water
discharge data from Gage 1 and Gage D-West data are comparable to discharge volumes recorded at
USGS 15297100. The peak flows and elevated winter discharge observed in HBC for the 2014 WY was
likely due to the increase in winter air temperatures in 2014 coupled with heavy precipitation events.
The lower discharge during the mid-summer period in 2014 was likely due to the lack of mountain
snow pack in the 2014 WY.
The cumulative water yield available for delivery to Terror Lake from the Upper Hidden Basin
Diversion Project for the 2014 WY is 29,585 ac ft. The D-West Diversion comprised 72%, 21,172 ac ft, of
the water yield while the D-East Diversion delivered the remaining 28%, 8,413 ac ft.
The proportion of surface water discharge contributed directly from the proposed Upper Hidden Basin
Diversion Project to the anadromous reach of the lower HBC cannot be accurately quantified through
surface water stream gaging alone due to the porous substrate in the mainstem of HBC causing flows
to go subsurface. Several ungaged catchments also contribute surface water and groundwater to the
mainstem HBC. The Middle and East Forks of HBC comprise substantial drainage areas along with
several unnamed tributaries not accounted for in the surface water measurements alone. The Upper
Hidden Basin Diversion Project comprises 15% of the entire HBC watershed, 3.8 mi2. The West Fork of
HBC comprises 47%, 11.8 mi2. The Middle Fork and East Forks of HBC comprise an additional 19%
(4.69 mi2) and 9% (2.2 mi2) respectively. The latter two forks of HBC were not gaged for this study and
as a result, their proportional contribution was not accounted for at Gage 3 using the surface water
measurements alone.
An alternative approach was used to compare the proportion of discharge contributed from each
headwater area in HBC by calculating the discharge based on drainage area size for each catchment.
Mean daily discharge for USGS Gage 15297100 and 15297110 was used to synthesize hydrographs for
the ungaged catchments in HBC for longitudinal comparisons of surface water yields. Surface water
discharge in the synthesized hydrograph is typically 2.5 times greater at Gage 2 compared to discharge
measures for the Upper Hidden Basin Diversion Project. Likewise, the synthesized discharge at Gage 3
is an additional two times greater than Gage 2 throughout the year. The addition of the Middle Fork
and East Fork in the discharge yield analysis indicates the Upper Hidden Basin Diversion Project
comprises a much smaller percentage of the overall water yield for Gage 3. The surface water data
collected in 2013 and 2014 did not include the Middle and East Forks in the overall hydrology balance
Hidden Basin Creek Hydrology and Fisheries Report KEA
ERM 48 2/11/2015
sheet. Surface water measures at Gage 3 in 2013 and 2014 also failed to quantify the contributions from
the Middle and East Forks because much of the contribution from these catchments, like the West Fork,
go subsurface and are not measurable using surface water sensors alone.
Prior to this study effort, little was known about the fish habitat and use in HBC. The study succeeded
in improving the local knowledge and understanding of fish distribution longitudinally in the
drainage. The objective of the fish trapping program was to document the presence / absence of fish
longitudinally in HBC. Wire-mesh minnow traps were used to sample juvenile and adults less than 200
mm at the four stream gage locations and Site 1b in HBC. Adult spawning fish distribution was
documented using helicopter flights combined with ground observations.
The lower three miles of HBC, the mainstem, is listed in the AWC and is known to support chum and
pink salmon, as well as Dolly Varden. In 2014, minnow trapping efforts associated with this study
confirmed coho salmon was another anadromous fish species inhabiting the drainage seasonally. Coho
were not previously listed in the AWC for the mainstem of HBC. The results from the 2014 fish
collection efforts have been presented to ADFG so the AWC can be updated to include coho.
Fish were not present at Gage D-West or Gage D-East. Resident Dolly Varden were collected in small
numbers (three individuals) at Site 1b on two out of four sampling efforts in 2014. Site 1b is located
upstream of Waterfall A, a presumed barrier to upstream fish migration. No other fish species were
observed upstream of Waterfall A.
At Gages 2 and 3, juvenile coho, Dolly Varden, and sculpin species were observed throughout the four
sampling events in 2014 (May, July, August, and October). Adult pink and chum salmon were
observed in August 2014 in the mainstem of HBC downstream of Gage 3. In October 2014, adult coho
and Dolly Varden were observed in the mainstem of HBC. No adult fish were observed more than 200
ft upstream of Gage 3.
While renowned for their homing ability, salmon are also highly opportunistic and capable of
exploiting marginal or newly available habitat for their various life stages (Healey 2009). The fact that
portions of the mainstem HBC experiences discontinuous flow during late summer in some years
suggests adult pink and chum salmon (and potentially coho salmon) make use of the system
opportunistically for spawning under suitable flow conditions. Based on the prevailing gradient and
substrate, most, if not all, of this opportunistic spawning likely occurs in the mainstem. Although the
Middle, East, and West Forks of HBC have continuous flow, it is unlikely salmon spawn in them due to
the steep gradient, large substrate (boulders) and presence of waterfalls a short distance upstream from
the confluence with the mainstem. Spawning may occur at the mouth of the unnamed tributaries
entering the mainstem, but the substrate size and presence of barriers upstream on these tributaries is
unknown at this time. Fish occupying pools in the mainstem of HBC that are seasonally dewatered are
not likely to survive the winter unless the pool has sufficient depth and food resources.
As referenced above, during the majority of the time, the mainstem of HBC is dry between Gage 2 and
Gage 3 with intermittent, disconnected pools. Based on field observations, the dry stream channel
between gages 2 and 3 is the more normal condition.
The anadromous and resident fish found in the mainstem of HBC have likely adapted to the stochastic
nature of the surface water flows. Fish habitat between Gage 2 and Gage 3 is limited spatially and

temporally. The dry stream channel in this reach presents a migration barrier for adults and juveniles.
During storm events or periods of high run-off, fish may access the mainstem of HBC between Gage 2
and Gage 3 opportunistically but are likely to be trapped in pools with limited resources (dissolved
oxygen, food) making them more vulnerable to disease, competition, and predation. Downstream of
Gage 3, HBC appears to maintain surface water connectivity to the marine environment at Hidden
Basin Bay. The longitudinal movement of anadromous and resident fish in the mainstem of HBC is
largely restricted to the stream reaches with available surface water, namely the reach downstream of
Gage 3. Water diversions at the Upper Hidden Basin Diversion Project are not likely to impact
available fish habitat in the reach below Gage 3. The Upper Hidden Basin Diversion Project comprises
only 15 percent of the overall HBC watershed area. Surface water flows downstream of Gage 3 are
continuous.

TEMPERATURE ANALYSIS DISCUSSION
Water temperature was continuously recorded at five stream gage locations in HBC in 2013 and
2014. Stream temperature monitoring coincided with establishment of stream gages at
respective locations beginning in April 2013 at Gage 2 and 3 and June 2013 at Gage 1. Gages D-
East and D-West were established on February 06, 2014 and May 16, 2014 respectively. Gage 1
was discontinued on July 14, 2014 due to installation of Gage D-West in closer proximity to the
proposed diversion. Damage to Gage 2 from high flow events resulted in intermittent loss of
temperature data.
In 2013 and 2014, daytime water temperatures were typically warmer in the headwater gage
locations (Gage 1, Gage D-West and Gage D-East) compared to the lower elevation gages (Gage
2 and Gage 3). Gage 1 exhibited the broadest annual temperature fluctuations in 2013 compared
to Gage 2 and Gage 3 (Figure 1). In 2013, Gage 1 recorded the highest summer water
temperatures of the three gages located longitudinally in HBC, 14.9 ◦C on August 24, 2013
(Table 1). In contrast, at Gage 2 and Gage 3 maximum water temperature in 2013 was 11.7 ◦C.
In 2014, maximum water temperatures at Gage D-West and Gage D-East were 13.4 and 12.7 ◦C
respectively, similar to temperatures recorded at Gage 1.
Overall, Gage 3 exhibited the narrowest annual temperature fluctuation in 2013 and 2014
compared to the other gages in the watershed. Surface water flow at Gage 3 is derived
primarily from groundwater upwellings just upstream from the gage location except during the
peak of the snowmelt hydrograph in June and peak flows during large precipitation events.
Stream temperatures in the proximity of groundwater upwelling zones are typically cooler than
adjacent surface water and exhibit less fluctuation over a 24-hour period.
To further examine stream temperatures, diel fluctuations at the respective gage locations five
different 48-hour periods occurring in July and August of 2014 were analyzed. On July 2-3,
2014, Gage 1 located in the headwaters displayed the lowest stream temperatures both day and
night compared to the other four gages located further downstream (Figure 2). These low
daytime stream temperatures in early July were likely influenced by the close proximity of
melting snow. Gage D-West, Gage D-East and Gage 2 all exhibited similar daily maximum
temperatures close to 10 ◦C. In contrast, Gage 3 daily maximum was only 8.2 ◦C and had the
narrowest diel temperature fluctuation (2.8 ◦C) compared to the other four gages (Table 2). On
July 20-21, 2014, diel temperature fluctuations were again more pronounced at Gage D-West,
Gage D-East and Gage 2 compared to Gage 3 (Figure 3). The diel temperature range at Gage 3
was 1.4 ◦C during this 48-hr period (Table 3). The Gage 3 maximum temperature during the
July 20-21 period was 7.9 ◦C, 4.6 and 3.8 ◦C less than Gage D-West and Gage D-East
respectively. On August 3-4, 2014, the contrasts in diel stream temperature fluctuations between
Gage 3 and the upstream gages were even more pronounced than July (Figure 4). The daily
maximum temperature at Gage 3 was 8.0 ◦C compared to 10.8, 10.4 and 11.1 ◦C at Gage D-West,
Gage D-East and Gage 2 respectively. On August 17-18, 2014, diel fluctuations in stream
temperatures at Gage 3 exhibited similar but slightly lower values as those at Gage D-West,
Gage D-East and Gage 2 (Figure 4). The maximum stream temperature at Gage 3 was 10.0 ◦C

(Table 5), substantially greater than other 48-hour periods. The increased stream temperature at
Gage 3 August 17-18, 2014 might be due to increased surface water discharge from precipitation
falling August 7-16, 2014. Stream temperatures recorded on August 17-18 were likely a
reflection of the surface water flows between Gage 2 and Gage 3 overwhelming the water
temperatures at Gage 3 typically associated with groundwater. Surface water discharge on
August 17 at Gage 3 was 187.9 cfs compared to discharge of 3.1 cfs on August 3, 2014 when
differences in stream temperature between Gage 3 and upstream gages were most pronounced.
On August 20-21, 2014, Gage 3 stream temperatures were again substantially lower compared
to Gage D-West, Gage D-East and Gage 2 (Figure 6). Maximum stream temperature at Gage 3
was 9.2 ◦C compared to 12.4, 12.2 and 11.5 ◦C at Gage D-West, Gage D-East and Gage 2
respectively (Table 6). Analysis of the 48-hour time periods during the summer months
indicates that Gage 3 maximum stream temperatures are substantially lower than upstream
gage locations except when continuous surface water discharge between Gage 2 and Gage 3
occurs during high precipitation events.
The dates selected for the 48-hour periods correspond to the warmest days recorded for the
months of July and August, 2014 in Kodiak, AK (Source:
http://www.usclimatedata.com/climate/kodiak/alaska/united-states/usak0133). July 2-3 and
July 20-21 were the warmest recorded in the City of Kodiak for the summer 2014 (Figure 7).
August 2014’s warmest 2-day periods were Aug 2-3 and 17-18. The 2-day period of August 20-
21 was also warm, but not the hottest (Figure 8).

1. INTRODUCTION
Kodiak Electric Association (KEA) operates the Terror Lake Hydroelectric Project
located approximately 20 miles southwest of Kodiak on the Kizhuyak River. The Terror
Lake Hydroelectric Project produces 80% of KEAs electric generation capacity. Water is
diverted from the Terror Lake reservoir to the generation plant through an
approximately 5-mile-long power tunnel. KEA is proposing to divert additional water
from Upper Hidden Basin Creek (UHBC), the drainage to the east of Terror Lake (Figure
1). The diverted water would supplement Terror Lake’s water supply and be used to
generate power from KEAs existing Terror Lake Hydroelectric Project (FERC Project
No.2743). The proposed diversions would require the construction of an approximately
3 mile long road to access the proposed diversion sites. The road would extend from the
existing Terror Lake access road, south to the proposed diversion sites (Figure 1),
requiring a Clean Water Act Section 404 permit from the U.S. Army Corps of Engineers
(USACE) to place fill into any Waters of the U.S. (wetlands and waters) crossed by the
proposed road. Therefore, KEA requested a preliminary assessment of potential
wetlands and waters along the potential route that might be subject to a USACE Section
404 permit.
This report provides a preliminary assessment of wetlands and waters along the
potential road corridor. It is intended to be a cursory assessment with the purpose of
guiding initial engineering designs. It is not a formal delineation of wetlands and
waters.
1.1. Study Area
The study area includes the area between the existing Terror Lake access road in the
north, and the proposed diversions (D-East and D-West) in the south (Figure 1). All
locations between the steeper valley walls were considered potentially suitable for
placement of the access road.

2. METHODS
The preliminary wetlands and waters assessment employed a three step approach: 1)
GIS-based desktop pre-mapping; 2) field groundtruthing using visual observations; and
3) GIS-based post-field editing of the desktop pre-mapping. In an effort to guide the
desktop mapping a 2000 foot wide mapping corridor was created in ArcGIS using a
topographic map. This mapping corridor roughly followed the valley floor (Figure 1).
A wetland scientist completed the desktop pre-mapping within the mapping area by
manually digitizing all potential wetland or waters features in ArcGIS. The following
base layers from the Geographic Information Network of Alaska (GINA,
www.gina.alaska.edu) were used to digitize the wetlands and waters: the best available
true color aerial orthoimagery, National Hydrography Data layer (NHD), U.S. Fish and
Wildlife Service National Wetlands Inventory (NWI) layer, georeferenced topographic
maps (100 foot contours), and a hillshade layer displaying terrain contours. Digitized
wetlands and waters polygons were classified using the NWI wetlands classification
system (Cowardin et al 1979).
Two ERM scientists conducted the field groundtruthing of the wetlands and waters pre-
mapping on July 17, 2014. They walked from north to south, observing all of the
polygons that identified in the pre-mapping exercise. Observations were documented
using a handheld GPS unit, photos, field notebook, and edits drawn on the field maps.
The field-based observations were then used to update the wetlands and waters
mapping in ArcGIS. “Wetlands” were defined as any area with greater than 30%
vegetation cover, that lacked a bed and bank, and ordinary high water mark (e.g. non-
stream areas), and possessed wetland vegetation (as defined by the USFWS National
Wetlands Inventory plant list) and any observable wetland hydrology or hydric soils.
Soil pits were not dug during this preliminary investigation. “Waters” were defined as
areas having less than 30% vegetation cover, with a distinct channel bed and bank, and
indications of an ordinary high water mark (OHWM).
Linear features too narrow to be mapped as polygons in ArcGIS (e.g. less than 15 feet
wide, including narrow stream channels) were mapped as line features. All other
wetlands and waters were mapped as polygons. This resulted in two GIS geodatabase
feature classes, polygons and lines.
Note that given the lower resolution of the aerial imagery, especially at the southern end
of the mapping corridor where the imagery was of very poor resolution, it was not
always possible to accurately map potential boundaries in the desktop phase. Further,
the field effort was not intended to provide comprehensive groundtruthing and
delineation of the entire potential road corridor; rather it was intended to provide a
cursory groundtruthing effort suitable for preliminary engineering planning of the road
alignment. As such, every effort was made to be conservative towards including
questionable area as a wetland or water, rather than excluding it.
Lastly, because the purpose of this report was to provide a cursory assessment as part of
developing the potential road alignment, total area or linear feet of wetlands and waters
was not calculated nor tabulated as part of this report. Wetlands and waters will instead

be delineated and quantified as part of the formal wetland and waters delineation for
Section 404 permitting for the project.

3. RESULTS
The ERM field team walked the length of the mapping corridor, from the Terror Lake
Access Road in the north, south to the proposed East and West diversions located on
Upper Hidden Basin Creek. They were able to groundtruth and confirm potential
wetlands or waters for each of the desktop-mapped wetlands and waters polygons on
the preliminary field maps. Results of the post-field mapping are presented in Appendix
A, Maps 1-6. Due to the poor aerial image resolution at the southern end of the mapping
corridor, most of the area depicted on Map 6 was mapped as a single large wetland
polygon. This area is likely a mosaic of wetland and non-wetland areas that (as with
most of the mapping corridor) will require detailed wetland delineation.
Table 1 presents the single wetland type, and the three different waters types that were
identified within the wetlands/waters mapping area, as defined by Cowardin et al.
(1979). The wetland type was palustrine emergent/scrub shrub, characterized by
herbaceous vegetation and low or dwarf shrubs. These wetlands were located along the
stream corridors (Figure 2), or as depressional bogs/marshes (Figure 3). Three types of
waters were identified, riverine intermittent stream bottom (Figure 4), riverine upper
perennial unconsolodated bottom (Figure 5), and palustrine unconsolodated bottom
(ponds) (Figure 6). The riverine water channel types were either deep incised canyon
channels (Figure 7), alpine rivulets (Figure 8), or braided gravel bed streams (Figure 9).
Ponds were typically very fine sand or silt substrate, many of which were dry at the time
of the field survey (Figure 10).

Dear Ms. Richcreek:
Re: Stream Gauge – Hidden Basin Creek
Stream No. 259-41-10077
Section 27, T. 30 S., R. 23 W., S.M.
Pursuant to AS 16.05.871(b), the Alaska Department of Fish and Game, Division of Habitat, has reviewed
your request to install and monitor stream gauge measurement devices at three locations in Hidden
Basin Creek.
Project Description
You propose to install and monitor one stream gauge that will be located in the specified anadromous
reach of Hidden Basin Creek. Two additional gauges will be located upstream of the specified reach.
The bubbler-style gauges will be installed by using a steel pipe driven into the streambed and attached to
the streambank. The gauges will be monitored by up to four personnel throughout the year. Access to
the sites will occur by helicopter. The purpose of the project is to quantify the available water resource
for potential future hydropower diversion to the Terror Lake hydroelectric facility. The gauges will be
used for five years.
Anadromous Fish Act
Hidden Basin Creek has been specified as being important for the spawning, rearing, or migration of
anadromous fishes pursuant to AS 16.05.871(a). Hidden Basin Creek is known to support chum and pink
salmon, as well as Dolly Varden.
In accordance with AS 16.05.871(d), project approval is hereby given subject to the project description
above and the following stipulation:
1. The streambanks shall not be altered in any way to install the gauges.

during project activities. Please be advised that this determination applies only to activities regulated by the
Division of Habitat; other agencies also may have jurisdiction under their respective authorities. This
determination does not relieve you of your responsibility to secure other permits; state, federal, or local.
You are still required to comply with all other applicable laws.
In addition to the penalties provided by law, this permit may be terminated or revoked for failure to comply
with its provisions or failure to comply with applicable statutes and regulations. The department reserves
the right to require mitigation measures to correct disruption to fish and game created by the project and
which was a direct result of the failure to comply with this permit or any applicable law.
You shall indemnify, save harmless, and defend the department, its agents, and its employees from any and
all claims, actions, or liabilities for injuries or damages sustained by any person or property arising directly
or indirectly from permitted activities or your performance under this permit. However, this provision has
no effect if, and only if, the sole proximate cause of the injury is the department’s negligence.
This permit decision may be appealed in accordance with the provisions of AS 44.62.330-630.
Any questions or concerns about this permit may be directed to Habitat Biologist Will Frost at 267-2813 or
emailed to william.frost@alaska.gov.

list" or the "surplus lines insurance list." The broker/agent must be licensed to do business in the

adequate to protect the Permittee and Permittor (the State, its officers, agents and employees)
relative to the liability exposures of the Permittee's commercial operations.

Alaska will rely upon the best professional judgment of the licensed insurance agent and, at
renewal, the agent's annual re-assessment of the insured's liability exposure for determination of
adequate levels of coverage. The State of Alaska reserves the right to require additional coverage
if, in its discretion, it determines that it may be warranted. Any changes in the approved permit

RE: Terror Lake Hydroelectric Project, FERC No. 2743
Electronic Filing
Application for Non-Capacity Amendment to License -Upper Hidden Basin Diversion
Request for Species List
Dear Ms. Lance,
Kodiak Electric Association, Inc. (KEA), licensee for the Terror Lake Hydroelectric Project, FERC No. 2743
(Project), proposes to file an Application for Amendment to License with the Federal Energy Regulatory
Commission (FERC) to enable the construction of the Upper Hidden Bas i n Diversion. The proposed
Upper Hidden Basin Diversion is a new diversion in a location where there is no existing dam or
diversion; therefore, KEA seeks to engage in the consultation requirements as per 18 CFR 4 .38.
The proposed Upper Hidden Basin Diversion is located in the mountainous uplands of Kodiak Island,
Alaska , at approximately 57" 36' 30" North, 153• 0' 10" West. Enclosed are maps illustrating the project
lo cat ion and conceptual design layout. This new diversion would supplement the available water supply
for the existing Project by ca pturing additional snow melt and rain in the upp er reache s of the Hidden
Basin watershed and conveying it westward through a mountain ridge to the existing Terror Lake
reservoir. Structural components for th e proposed diversio n would consist of two dam embankments
co nnected by an approximately 0.6 mile long conveyan ce pipe, a 1.2 mile lon g subterranean tunnel to
the Terror Lake reservoir, and a 4 mile long gravel road for construction and future maintenance
access. The diversion components would be a basic, non-mechanical design intend e d for un-manned
water conveyance. Once the additional water re so urce from the Upper Hidden Basin Diversion flows
into the Terror Lake reservoir, hydropower would be generated from the existi ng Project powerhouse
and fed directly into KEA's existing grid without any operational changes or any other capacity-related
modifications . Thi s new diversion would enhance the existing Project and allow KEA to provide a
continuous su pply of renewable energy to the communities of Kodiak as electrical demand co ntinues to
grow.
In a letter dated April17, 2015, FERC de signated KEA as their non-federa l r epresen t ative for the purpose
of conducting informal consultation with the US Fish and Wildlife Service (USFWS) pursuant to the
regulation s at SO CFR 402 .08 implementing Section 7 of the Endan ge red Sp ecies Act (ESA).
KEA here in requests a copy of the current species list for the Upper Hidde n Basin Diversion area .
Specifically, KEA is requesting information on federally endangered or threatened plant and animal
species, as well as pl ant and animal sp ecies of concern that are known or susp ect ed to occur in the
project area. If possible, it would be very helpful if your office could provide mapped locations of known
occurrences of these species and designated critica l habitats, if any, for such species in the region of this
project.
Endeavor to produce 95% of energy sales with cost effective renewable power solutions by the year 2020.

It is KEA 's intent to engage in the First Stage Consultation process w ith the Joint Agency/Public Meetings
held in Kodiak, Ala ska on July 21, 2015. Receiving information from your office regarding this species list
in advance of this meeting would be very helpful for stakeholder participation . KEA greatly appreciates
your response to this request at your earliest convenience.

Project Name: Terror Lake Hydroelectric Project, FERC License No. 2743, Ap
Subject:List of threatened and endangered species that may occur in your proposed project
location, and/or may be affected by your proposed project
To Whom It May Concern:
The enclosed species list identifies threatened, endangered, and proposed species, designated
critical habitat, and some candidate species that may occur within the boundary of your
proposed project and/or may be affected by your proposed project. The species list fulfills the
requirements of the U.S. Fish and Wildlife Service (Service) under section 7(c) of the
Endangered Species Act (Act) of 1973, as amended (16 U.S.C. 1531 ). Please note thatet seq.
candidate species are not included on this list. We encourage you to visit the following website
to learn more about candidate species in your area:
http://www.fws.gov/alaska/fisheries/fieldoffice/anchorage/endangered/candidate_conservation.htm
New information based on updated surveys, changes in the abundance and distribution of
species, changed habitat conditions, or other factors could change this list. Please feel free to
contact us if you need more current information or assistance regarding the potential impacts to
federally proposed, listed, and candidate species and federally designated and proposed critical
habitat. Please note that under 50 CFR 402.12(e) of the regulations implementing section 7 of
the Act, the accuracy of this species list should be verified after 90 days. This verification can
be completed formally or informally as desired. The Service recommends that verification be
completed by visiting the ECOS-IPaC website at regular intervals during project planning and
implementation for updates to species lists and information. An updated list may be requested
through the ECOS-IPaC system by completing the same process used to receive the enclosed
list.
The purpose of the Act is to provide a means whereby threatened and endangered species and
the ecosystems upon which they depend may be conserved. Under sections 7(a)(1) and 7(a)(2)
of the Act and its implementing regulations (50 CFR 402 ), Federal agencies are requiredet seq.
to utilize their authorities to carry out programs for the conservation of threatened and
endangered species and to determine whether projects may affect threatened and endangered
species and/or designated critical habitat.
A Biological Assessment is required for construction projects (or other undertakings having
similar physical impacts) that are major Federal actions significantly affecting the quality of the
human environment as defined in the National Environmental Policy Act (42 U.S.C. 4332(2)
(c)). For projects other than major construction activities, the Service suggests that a biological
evaluation similar to a Biological Assessment be prepared to determine whether the project may
affect listed or proposed species and/or designated or proposed critical habitat. Recommended
contents of a Biological Assessment are described at 50 CFR 402.12.
If a Federal agency determines, based on the Biological Assessment or biological evaluation,
that listed species and/or designated critical habitat may be affected by the proposed project, the
agency is required to consult with the Service pursuant to 50 CFR 402. In addition, the Service
recommends that candidate species, proposed species and proposed critical habitat be addressed
within the consultation. More information on the regulations and procedures for section 7
consultation, including the role of permit or license applicants, can be found in the "Endangered
Species Consultation Handbook" at:
http://www.fws.gov/endangered/esa-library/pdf/TOC-GLOS.PDF
Please be aware that bald and golden eagles are protected under the Bald and Golden Eagle
Protection Act (16 U.S.C. 668 ), and projects affecting these species may requireet seq.
development of an eagle conservation plan
(http://www.fws.gov/windenergy/eagle_guidance.html). Additionally, wind energy projects
should follow the wind energy guidelines (http://www.fws.gov/windenergy/) for minimizing
impacts to migratory birds and bats.
Guidance for minimizing impacts to migratory birds for projects including communications
towers (e.g., cellular, digital television, radio, and emergency broadcast) can be found at:
http://www.fws.gov/migratorybirds/CurrentBirdIssues/Hazards/towers/towers.htm;
http://www.towerkill.com; and
http://www.fws.gov/migratorybirds/CurrentBirdIssues/Hazards/towers/comtow.html.
We appreciate your concern for threatened and endangered species. The Service encourages
Federal agencies to include conservation of threatened and endangered species into their project
planning to further the purposes of the Act. Please include the Consultation Tracking Number in
the header of this letter with any request for consultation or correspondence about your project
that you submit to our office.

RE: Terror Lake Hydroelectric Project, FERC No. 2743
Electronic Filing
Application for Non-Capacity Amendment to License-Upper Hidden Basin Diversion
Request for Species List
Dear Ms. Walker,
Kodiak Electric Association, Inc. (KEA), licensee for the Terror Lake Hydroelectric Project, FERC No. 2743
(Project), proposes to file an Application for Amendment to License with the Federal Energy Regulatory
Commission (FERC) to enable the construction of the Upper Hidden Basin Diversion . The proposed
Upper Hidden Basin Diversion is a new diversion in a location where there is no existing dam or
diversion; therefore, KEA seeks to engage in the consultation requirements as per 18 CFR 4.38.
The proposed Upper Hidden Basin Diversion is located in the mountainous uplands of Kodiak Island,
Alaska, at approximately 57" 36' 30" North, 153" 0' 10" West. Enclosed are maps illustrating the project
location and conceptual design layout. This new diversion would supplement the available water supply
for the existing Project by capturing additional snow melt and rain in the upper reaches ofthe Hidden
Basin watershed and conveying it westward through a mountain ridge to the existing Terror Lake
reservo ir . Structural components for the proposed diversion would consist of two dam embankments
connected by an approximately 0 .6 mile long conveyance pipe, a 1.2 mile long subterranean tunnel to
the Terror Lake reservoir, and a 4 mile long gravel road for construction and future maintenance
access . The diversion components would be a basic, non-mechanica l design intended for un-manned
water conveyance. Once the additional water resource from the Upper Hidden Basin Diversion flows
into the Terror Lake reservoir, hydropower would be generated from the existing Project powerhouse
and fed directly into KEA's existing grid without any operational changes or any other capacity-related
modifications. This new diversion would enhance the existing Project and allow KEA to provide a
continuous supply of renewable energy to the communities of Kodiak as electrical demand continues to
grow.
In a letter dated April17, 2015, FERC designated KEA as thei r non-federal representative for the purpose
of conducting informal consultation with the National Marine Fisheries Service (NMFS) pursuant to the
regulations at 50 CFR 402 .08 implementing Section 7 of the Endangered Species Act (ESA), and pursuant
to regulations at 50 CFR 600.920 implementing Section 305(b) of the Magnuson-Stevens Fishery
Conservation and Management Act (MSA).
KEA herein requests a copy of the current species list for the Upper Hidden Basin Diversion area.
Specifically, KEA is requesting information on federally endangered or threatened plant and animal
species, as well as plant and an imal specie s of concern that are known or suspected to occur in the
project area . If possible, it would be very helpful if your office could provide mapped locations of known

occurrences of these species and designated critical habitats, if any, for such species in the region of this
project.
It is KEA's intent to engage in the First Stage Consultation process with the Joint Agency/Public Meetings
held in Kodiak, Alaska on July 21, 2015. Receiving information from your office regarding this species list
in advance of this meeting would be very helpful for stakeholder participation. KEA greatly appreciates
your re sponse to this request at your earliest convenience.

Subject:Re: P-2743: New Diversion Proposal at Terror Lake Hydroelectric Project - Species Request
Letter
Hi Jennifer -
Thanks for following up by phone today on the letter KEA sent to NMFS, dated April 28, 2015, requesting a
copy of the current species list for the Upper Hidden Basin Diversion area on Kodiak Island.
I have discussed this project with NMFS' Division of Protected Resources. There are no species under NMFS
jurisdiction and listed as endangered or threatened under the Endangered Species Act that are known or
suspected to occur in the project area, nor is there designated critical habitat for any such species in the project
area.
This precludes the need to consult informally with NMFS under Section 7 of the ESA for development of
KEA's proposed Upper Hidden Basin Diversion into the Terror Lake Hydroelectric Project, FERC Project No.
2743.
Thanks too for sharing the online tool of the USFWS for obtaining species lists. I've shared that with PRD and
perhaps NMFS could in the future develop a similar tool to streamline project planning and consultation.
Please let me know if there is anything more KEA requires for this project from NMFS.

Upper Hidden Basin Diversion – Site Development Plan
April 14, 2015
The scope of proposed activities to be conducted within the requested easement area includes
construction, operation and maintenance of a water conveyance system. The purpose of all
activity and improvements within this easement is for Kodiak Electric Association, Inc. (KEA) to
supply renewably‐generated electricity to the communities of Kodiak.
KEA is a rural electric cooperative that provides electricity to approximately 5,900 meters on
Kodiak Island, Alaska in a service area that includes the region in and around the City of Kodiak,
the US Coast Guard Base, Bells Flats, Chiniak, Pasagshak, and Port Lions. KEA is a not‐for‐profit
501(c)(12) cooperative organized under AS 10.25 for the purpose of supplying electric energy
and power to its members. KEA’s Bylaws, Articles of Incorporation, and IRS Determination are
provided as proof of eligibility for the exemption as per AS 38.05.850(b).
Hydropower generated by the Terror Lake Hydroelectric Project is KEA’s primary energy source.
Enhancing water availability to Terror Lake with a new water diversion allows KEA’s future
electrical load growth to be continually powered with renewable energy. The proposed Upper
Hidden Basin Diversion would supplement the available energy resources for the Terror Lake
Hydroelectric Project by conveying water from the upper reaches of the Hidden Basin
watershed to the existing Terror Lake reservoir. Once the supplementary water from the Upper
Hidden Basin Diversion flows into the Terror Lake reservoir, more renewable hydropower can
be generated from the existing Terror Lake Hydroelectric Project and fed directly into the KEA
grid. KEA’s existing powerhouse and electrical grid infrastructure is able to deliver the
additional power to the Kodiak community without any modifications.
The existing Terror Lake reservoir is located in the remote north central area of Kodiak Island,
approximately 30 miles southwest of the City of Kodiak. The proposed Upper Hidden Basin
Diversion project area is located east of the Terror Lake reservoir on the other side of a
mountain ridge. This mountain ridge between Terror Lake and the Upper Hidden Basin
watershed serves as the boundary for Federal and State land. The Terror Lake reservoir is on
Kodiak National Wildlife Refuge lands, and the proposed diversion project is on State lands.
Public use of the area is extremely minimal.
The general location of the easement request is approximately 57⁰ 35’ 37” N; 153⁰ 0’ 59” W.
Attached is a Site Location Map. The proposed diversion area straddles the edges of USGS
Quadrangle Maps Kodiak C‐3 and C‐4. A merged version of both USGS maps (scale of 1:
1:63,360) is provided to show the approximately easement request location, noted in blue. The
exact size and location of the requested easement are approximate at this stage of project
development. Additional surveying and mapping activities will be conducted in 2015 to define
the exact acreage of State land to be occupied by the proposed project. That information will
be provided to DNR when it becomes available.
Attached are photographs of the proposed easement area. This mountainous terrain is
typically inundated with snow from October to June. Ground cover ranges from bare bedrock
and unconsolidated colluvium to palustrine emergent wetlands and scrub shrub. There are no
trees in this upland, alpine area. Access to this remote site is provided by helicopter, or by
backcountry hiking from the existing Terror Lake Hydroelectric Project access road. The existing
Terror Lake Hydroelectric Project access road is a remote road used exclusively for KEA’s official
use for the operation and maintenance of the existing Terror Lake Hydroelectric Project, and it
is accessible only by floatplane, boat, or helicopter. Attached is a photograph of the existing
Terror Lake Hydroelectric Project access road and the area where a new diversion access road
would be sited.
Attached is a conceptual layout of the proposed Upper Hidden Basin Diversion. It is a basic,
non‐mechanical conveyance of water, with spur road accessibility. Site development would
consists of 4 miles of a pioneer gravel road connecting the existing Terror Lake Hydroelectric
Project access road to two small dam embankments. The eastern dam embankment (D‐East)
would convey water to the western dam embankment (D‐West) through a buried 0.4 mile pipe.
From the D‐West location, the water would be conveyed to the existing Terror Lake reservoir
through a 1.2 mile subterranean tunnel running underneath the mountain ridge.
This project is currently in the development phase. To assess the quantity of water available for
diversion, KEA is currently collecting stream gauging data in this watershed as authorized by
Land Use Permit LAS 29042. The final engineering design for the temporary and permanent
structures, the exact construction methods, and defined inventory of construction equipment
needed to build the road, diversion dams, conveyance pipe and tunnel are not yet determined.
It is KEA’s intent to finalize the engineering design and secure construction contacts in 2018,
initiate construction in 2019, and operate the new diversion by 2020. The as‐built diversion
and access road will not generate, use, store, transport, dispose of or otherwise come in
contact with toxic and/or hazardous materials. The as‐built diversion will not involve any
storage tanks, either above or below ground. There would be no machinery left on site when
construction activities are complete.
The Terror Lake Hydroelectric Project is a federally licensed hydropower facility as Federal
Energy Regulatory Commission (FERC) Project No. 2743. Adding the Upper Hidden Basin
Diversion to the Terror Lake Hydroelectric Project requires a FERC License Amendment, which is
a formal process of coordinated multi‐agency consultation and public scoping. Through this
multi‐year FERC License Amendment process, KEA will be refining the diversion project design,
working with stakeholders to identify potential resource impacts, and developing project‐
specific plans and measures to minimize potential impacts. The Alaska Department of Natural
Resources (DNR) is a key stakeholder in KEA’s FERC License Amendment process. As the Upper
Hidden Basin Diversion design develops and more information becomes available, DNR will be
notified and provided with that information.

RE: Application for Water Right ‐ Upper Hidden Basin Diversion
Dear Mr. Reese,
Kodiak Electric Association, Inc. (KEA), licensee for the Terror Lake Hydroelectric Project, FERC No. 2743
proposes to construct a new water diversion system in the Upper Hidden Basin watershed to convey
additional water resources to the Terror Lake reservoir. The majority of the proposed Upper Hidden Basin
Diversion project area is located on lands owned by the State of Alaska, managed by the Alaska
Department of Natural Resources (DNR).
As was discussed during our pre‐filing consultation meeting on April 10, 2015, KEA herein files an
Application for Water Right as per AS 46.15 for approximately 45,000 acre‐feet of surface water to be
diverted by the Upper Hidden Basin Diversion Project to the existing Terror Lake reservoir. The purpose
of this water diversion is to increase the amount of hydropower resources available to the Terror Lake
Hydroelectric Project so additional renewable energy may be generated for the benefit of Kodiak Island
and Alaska.
As per the instructions specified on the Application for Water Rights form, enclosed please find the
following:
1. Completed Application for Water Right Form for the headwater tributaries to Upper Hidden
Basin Creek;
2. FERC License No. 2743, which serves as the possessory interest document for the Terror Lake
Hydroelectric Project, which is where the water will be used;
3. Completed Application for Easement filed with DNR on April 15, 2015 requesting legal access to
the water withdrawal point;
4. Upper Hidden Basin Diversion conceptual project layout drawing;
5. USGS Quadrangle Maps Kodiak C‐3 and C‐4 indicating the location of the headwater tributaries
to Upper Hidden Basin Creek to be diverted; and
6. Hidden Basin Creek Hydrology and Fisheries Technical Report, prepared by ERM in February
2015.
There are items listed in the form’s instructions that are not applicable to this project, and therefore are
not provided. The Upper Hidden Basin Diversion is a surface water diversion project; therefore there
are no drilled wells associated with the project. There is no ADEC water or wastewater system
certificate associated with this project. The headwater tributaries to Upper Hidden Basin Creek area not
anadromous water bodies identified or specified under AS 16.05.871(a); therefore a fish habitat permit
is not applicable. The Upper Hidden Basin Diversion is not fully developed; therefore a notarized
Upper Hidden Basin Diversion
Application for Water Right
Page 2 of2
Statement of Beneficial Use of Water form and associated fee is not available. Alaska withdrew from
the National Coastal Management Program under the Coastal Zone Management Act and no longer has
an Alaska Coastal Management Program (ACMP) as of July 1, 2011; therefore a Coastal Project
Questionnaire is no longer applicable.
KEA is willing to provide a non-refundable fee for processing this applicati on; however the fee for
hydroelectric power generation is not yet defined. As was discussed during our pre-filing consultation
meeting on April10, 2015 and on our phone conversation on May 4, 2015, the application fee for this
specific water use will be determined after KEA's application is deemed complete.
Thank you for providing guidance on how KEA may receive timely water use authorization from the DNR
for the development, construction and operation of the Upper Hidden Bas i n Diversion project. If you
have any questions or require additional information, please do not hesitate to contact me at (907) 654-
7667 or by e-mail at jri~hcreek@kodiak.coop.

PUBLIC SAFETY PLAN
TERROR LAKE HYDROELECTRIC PROJECT
FERC PROJECT NO. 2743
Introduction
Kodiak Electric Association, Inc. (KEA), licensee for the Terror Lake Hydroelectric Project FERC
No. 2743 (Project), is responsible for notifying the public of potential public safety hazards
within the Project area. In accordance with 18 CFR §12.4 and §12.42, this document serves as
KEA’s Public Safety Plan.
Project Description
The Terror Lake Hydroelectric Project is the primary source of electricity for KEA’s service area
on Kodiak Island. It is a remotely‐located, trans‐basin hydropower development that captures
water from the Terror River drainage and transports it by means of an un‐pressurized tunnel to
a powerhouse located in the Kizhuyak River valley. Power is transmitted to the City of Kodiak
by 17‐mile long transmission line that crosses over a mountain pass. The Project is the only
development in the area, and is accessible only by floatplane, boat or helicopter.
Within the Project boundary, there are 15 miles of gravel road beginning at the Project’s
dock/jetty area located at the head of Kizhuyak Bay and ending at the Terror Lake reservoir
located up in the mountains. This Project access road is not connected to any other road
system on Kodiak Island, and all infrastructure associated with the Project is intended for
official use only.
The Terror Lake reservoir and dam are located within the Kodiak National Wildlife Refuge.
Infrastructure located within the vicinity of reservoir includes the main power tunnel’s intake
gate building and the outlet works valve house. The Terror River valley downstream of the dam
embankment and outlet works valve house is completely undeveloped.
The Project powerhouse is located in the Kizhuyak River valley, approximately 5 miles northeast
of the Terror Lake reservoir. Infrastructure within the powerhouse area includes the substation,
staff housing, warehouse, and mechanic shop building. The powerhouse contains three 11.25
megawatt turbine‐generator units, and each unit comprises a vertical shaft 6‐jet Pelton turbine
and synchronous generator. Two of these three units were authorized in the Original License
issued on October 5, 1981, and began commercial operation in 1985. The third unit was
authorized in a license amendment issued on February 17, 2012 and began commercial
operation in 2013.
Public Use
No recreational facilities are located in the immediate Project area, and public use is essentially
non‐existent. In correspondence dated June 17, 1997, the Commission exempted the Project
from filing the Hydropower Development Recreation Report (FERC Form 80) because of the lack
November 2013
of recreational use at the Project. Due to its low hazard potential and remote location, KEA has
remained exempt from Emergency Action Plans requirements since its original construction.
Despite the lack of public use in the Project area, KEA maintains an informational kiosk near the
dock/jetty area to inform any visiting public about the Project area, including bear safety
information and land use policies of the area’s landowners. This kiosk contains a sign‐in
booklet for the public to document their visit. Safety information posted at this kiosk includes
warnings that tampering with utility equipment is dangerous, and that no firearms may be
discharged within a half‐mile of the powerhouse area.
In accordance with 18 CFR §8, KEA also maintains an informational sign in this area to inform
the public about Project features.
November 2013
Inventory & Location of Public Safety Devices
The Public Safety devices utilized in the Project area consist of gates, signs, and fences. An
itemized inventory of these devices is provided below, followed by a schematic drawing that
shows the location of each listed device by number. The devices listed in this plan are those
items maintained for the public; occupational safety devices maintained for Project staff are
not listed in this Public Safety plan.
1) Motorized vehicle access gate located
at dock/jetty area near informational
kiosk.
2) Warning signs located at two points along the
gravel road a half‐mile from the powerhouse area.
3) Motorized vehicle access gate located
at intersection turn toward the Kodiak
National Wildlife Refuge area.

MEMORANDUM OF UNDERSTANDING
between
Kodiak Electric Association, Inc.
PO Box 787
Kodiak, AK 99615
Phone: (907) 486‐7704
and
Afognak Native Corporation
215 Mission Road, Suite 212

This Memorandum of Understanding (MOU) pertains to the collaborative partnership between Kodiak
Electric Association, Inc. (KEA), Afognak Native Corporation (ANC) and the Alutiiq Museum &
Archaeological Repository (Alutiiq Museum) to conduct periodic monitoring of KOD‐190 through the
Alutiiq Museum’s Site Stewardship Program.
Archeological Site KOD‐190 has been interpreted to be a seasonally occupied fish camp eligible for
inclusion in the National Register of Historic Places. Based upon KEA’s consultation with the State
Historic Preservation Office (SHPO) under Section 106 of the National Historic Preservation Act, periodic
monitoring of this site through the Alutiiq Museum’s Site Stewardship Program has been approved as an
appropriate measure for monitoring the condition of the site to identify any adverse effects to this
historic property, should that occur.
KOD‐190 is located on land owned by the ANC; it is not within KEA’s Terror Lake Hydroelectric Project
boundary. Therefore, access to the site must be granted by ANC. This MOU serves as written
permission from ANC for KOD‐190 to be included in the Alutiiq Museum’s Site Stewardship Program.
The Site Stewardship Program is administered by the Alutiiq Museum. As partners in this program, a
Registered Professional Archeologist from the Alutiiq Museum will train KEA and ANC representatives in
May 2011 to act as site stewards. By training staff from both organizations, representatives of either
ANC or KEA would be able to complete an annual site evaluation and report the results to the Alutiiq
Museum for inclusion in the Program Report. It is the intention of ANC that their organization be
responsible for the periodic monitoring work in future years; however, if ANC representatives are
unable to conduct the work in a future year, then KEA representatives can step in to ensure continuous
monitoring each year.
It is the intention of all parties to continue this arrangement as long as the Site Stewardship Program
exists and all parties desire the collaboration. For the purpose of administering this agreement, the
term of the MOU shall be for a period of ten years, expiring in the spring of 2021, dependent upon the
Alutiiq Museum’s continuation of their Site Stewardship Program. If the Alutiiq Museum’s Site
Stewardship Program ceases to exist, then this agreement shall be terminated.
Any party may cancel this agreement by providing a 30‐day notice in writing.
Based upon KEA’s consultation with the SHPO, Howard Valley of ANC, and Amy Steffian of the Alutiiq
Museum, this MOU establishes the following responsibilities for each party.
Kodiak Electric Association:
• Obtain written permission from the Afognak Native Corporation for KOD‐190 to be included in
the Alutiiq Museum’s Site Stewardship Program. (This signed MOU serves as the written
permission.)
• Enter into an Archaeological Service Agreement with the Alutiiq Museum to pay for curator
Patrick Saltonstall’s time to visit KOD‐190, train KEA and ANC representatives as site stewards,
and provide 2011 baseline site documentation to establish the monitoring program. (The signed
Archaeological Services Agreement is attached to this MOU.)
• Provide at least one representative to travel to KOD‐190 and be trained as a site steward by Mr.
Saltonstall in May 2011.
• Complete annual site monitoring following the basic protocols of the site stewardship program if
ANC representatives are unable to complete annual site monitoring. KEA will be notified if this
necessary by September 1st of each year.
• Provide site monitoring information to the Alutiiq Museum when collected.
• Notify ANC when KEA representatives enter onto ANC lands for the purpose of monitoring KOD‐
190.
• Complete and submit any SHPO required reporting, as necessary for demonstrating compliance
with FERC License No. 2743.
• Consult with ANC as needed about site disturbances, if any are discovered.
Afognak Native Corporation:
• Provide written permission to KEA for KOD‐190 to be included in the site stewardship program
under the condition that that ANC is notified when KEA representatives enter onto ANC lands
for the purpose of monitoring KOD‐190. (This signed MOU serves as written permission.)
• Provide at least one representative to travel to KOD‐190 and be trained as a site steward by Mr.
Saltonstall in May 2011.
• Provide boat travel to and from KOD‐190 to train site stewards.
• Complete annual site monitoring following the basic protocols of the site stewardship program.
This includes providing transportation for the ANC site stewards to and from the site.
• Provide site monitoring information to the Alutiiq Museum, as collected, by October 31st of each
year. Information provided will include digital photos and field notes.
• Notify KEA if ANC site stewards are not available to complete annual monitoring. Notification
shall be provided to KEA by September 1st of each year.
• Consult with KEA as needed about site disturbances, if any are discovered.
Alutiiq Museum:
• Establish an Archaeological Service Agreement with KEA for Mr. Saltonstall’s time for the May
2011 site steward training.
• Provide Mr. Saltonstall to travel to KOD‐190 in May 2011 to train stewards and provide baseline
site documentation to establish the monitoring program.
• Review site monitoring data from KOD‐190 yearly and add it to the comprehensive Site
Stewardship database maintained by the Alutiiq Museum. This review will be brief and
equivalent to that given to all sites considered by the Program.
• Submit a copy of the annual Site Stewardship Program Report to the SHPO for their files. It
should be noted that KOD‐190 will be treated like every other site in the report in that it will be
listed in a table that shows the conditions observed at that site, and lists the monitor who
recorded the information. Sites are not individually discussed in this Report. This Report will
also be shared with the US Fish and Wildlife Service and the Kodiak National Wildlife Refuge,
sponsors of the broader Site Stewardship Program.
• Provide ANC with a digital copy of the annual Site Stewardship Program Report.
• Provide KEA with information on the condition of KOD‐190 to assist KEA reporting to the SHPO,
as necessary.
It should be very clear that the Alutiiq Museum’s Site Stewardship Program Report will not provide a
detailed summary of KOD‐190. Mr. Saltonstall will review site condition and include this site in a
summary table. The Report will not provide a narrative description of KOD‐190, describe its specific
condition, or detail changes in condition. Should it be necessary to develop a more detailed Report,
additional assistance with site documentation and reporting would need to be accomplished through a
separate Archeological Service Agreement.
The signatures below confirm all parties agreement with the terms and responsibilities listed in this
MOU.
