INTRODUCTION
LOCATION
Port Lions is located on Kizhuyak Bay, at the north end of Kodiak
Island in the Gulf of Alaska, 19 air miles west of the City of Kodiak.
BACKGROUND
The City of Port Lions was established after the earthquake of 1964
when residents of Afognak abandoned their village site.
The construction of Port Lions was funded by the Lions International
and the BIA.
Port Lions is home for approximately 60 families and a population of
about 250 persons.
GOVERNMENT
Port Lions is a second class city situated within the Kodiak Island
Borough and provides a number of services to the community, including
water and sewer facilities, fire protection, road maintenance, public
safety, and administrative services. The Borough provides schools,
planning, parks and recreation services.
TRANSPORTATION
A city-operated 2,600 foot gravel airstrip is located northeast of Port
Lions with Kodiak Western Airlines providing daily flights from Kodiak.
The community is also served by the Alaska Marine Highway System
with a weekly visit from the State ferry, M. V. Tustumena. The city
dock has approximately 16,000 square feet of usable surface area, and
the float has 800 linear feet of moorage space. The depth of the water
at the south face of the dock is 72 feet at MLLW.

ECONOMY
The economy of Port Lions depends largely upon fishing and fish processing.
The labor force consists of approximately 166 people. The types of
employment available are:

ELECTRIC SYSTEM
The Kodiak Electric Association, Inc. owns and operates a diesel -
electric plant and distribution system in the City of Port Lions. The
diesel-electric plant contains four units totaling 985 kW. (2-350 1 s,
1-200 and 1-85 kW).
Resident electrical consumer count has not shown an increase since
1972. The average number for this period is 66. The number of
resident consumers in August, 1979 was 66. KEA records indicate a
decline in both system peak ( kW) and energy (MWH) consumption since
the loss of the Wakefield cannery in 1975. However, the continued
decline since 1975 has been greatly influenced by the rapidly rising
cost of energy mainly attributable to the diesel fuel cost. In March, 1977,
KEA paid 53.6 cents per gallon for diesel fuel; in September, 1979, the
cost was 97.3 cents per gallon in Port Lions.

LAND STATUS
The tributary area for the Port Lions River is contained in Townships
26S and 27S and Ranges 22W and 23W of the Seward Meridian. This
area is shown on Figure 5. Determining the ultimate land ownership in
this area is a complex problem which will not be totally solved until
provisions of the Alaska Native Claims Settlement Act and all of their
ramifications are resolved.
Under Interim Conveyance No. 217 pursuant to provisions of the Act,
surface rights to those lands considered for a hydroelectric project on
the Port Lions River in Range 22W, Seward Meridian were conveyed to
the Afognak Native Corporation. Subsurface rights to the same lands
were conveyed to Koniag Regional Native Corporation under Interim
Conveyance No. 218.
Remaining lands tributary to the Port Lions River are in Range 23W,
Seward Meridian. Currently, title to these lands is in question. In
Township 27S of the Range, all tributary lands were selected by both
the Afognak Native Corporation and the State of Alaska as part of their
allotments. At this time, none of the land has been conveyed to either
party. However, Tentative Approval has been given to the State. In
Township 26S of the Range, all tributary lands were selected by the
State. Section 36 of this area was also a 11 Second Round 11 selection of
the native corporations. Again, at this time, none of the land has been
conveyed to either party and still belongs to the federal government.
Under Interim Conveyance No. 217, a 25 foot wide access trail easement
from Settler Cove to public lands to the west was established ( E IN D 9 28).
Also, a 25 foot wide continuous linear easement upland of and parallel
to the mean high tide line was established ( El N P 1).
The City of Port Lions has water rights to 3 cubic feet per second of
water from the Port Lions River watershed.

HISTORICAL TRENDS
Since the loss of the Wakefield cannery in 1975, KEA records indicate a
decline in both system annual peak kW, and net annual MWH consumption,
despite continued population growth. This decline appears to be leveling
out, and it is assumed that a stable condition now exists modifying
circumstances.
A. Planned Construction
The additional kW demand and annual MWH consumption from planned,
and current housing and public facility construction will cause an
increase in present requirements as estimated below:

It is assumed that these will be on line in 1982.
C. Industrial Development (Cannery)
Port Lions is presently doing all within its means to encourage the
reestablishment of a cannery. If successful, the addition of this
facility will have a major impact on the area's power requirements.
Assuming facilities with power requirements similar to the Kodiak
island seafood plant at Larsen Bay, an additional demand of
250-300 kW can be expected for salmon processing, and 800 kW if
freezing facilities are added to allow year around diversified
processing. Further, the addition of a cannery will indirectly
affect local power requirements by boosting the economy, and
encouraging the use of more 11 luxury 11 appliances. This indirect
effect is estimated to increase residential demand and consumption
5% per year for the first 5 years, and 3% per year thereafter.
For the Port Lion with cannery scenario, it is assumed that the
cannery goes on line in 1983.
-5-
APA10/A
D. Population Growth
Port Lions has experienced a steady 1% per year growth in popula-
tion since 1970. Given existing conditions, growth is expected to
continue at this rate, and residential demand and consumption is
assumed to increase proportionally.

GEOLOGY
In late August 1978, Mr. Robert M. Retherford, geologist for C.C.
Hawley and Associates, under contract to Robert W. Retherford Associates
conducted a field investigation of proposed hydroelectric power generation
site at Port Lions, Alaska. Mr. Retherford's report, prepared from
data collected and observations made at Port Lions, is presented in the
following paragraphs. Brief notes from the reconnaissance are presented
on the large drawings included in the Appendix of this report.
GENERAL GEOLOGY
Shale also underlies the Port Lions area. The shale nearly flat-lying is
well cemented and fresh. Overburden is quite thin in most of the areas
of proposed construction; it is estimated at three to eight feet in depth.
More organic debris has collected--two to three feet--and the Katmai
Ash is much thicker than at either Old Harbor or Larsen Bay.
POWERHOUSE
The proposed powerhouse site is located just above high tide on backshore
gravels. Foundation for a small powerhouse should be no problem but
protection from extremely high tides and/or winds should be carefully
considered.
PENSTOCK ROUTE
The penstock can run parallel and just to the south of the present
stream channel. Anchorage to bedrock, if necessary, should require
removal of only a few feet of topsoil and gravel.
-10-

'

l

APA10/A
DAMSITE
The damsite, as proposed, will not economically allow a dam of any
height to be built. Four feet or so would probably be the maximum
height. The whole system may not require a very large reservoir,
however, as the drainages are already regulated to some extent by
large lakes. There is certainly no particular geologic problem with a
four foot earthfill dam.
RECOMMENDATIONS
1. Discharge of the streams should be carefully recorded.
2. Comparison of flow throughout the year should determine how large
a reservoir is required.
3. Determine whether one of the lakes might be modified to allow more
regulation.
4. If not, determine other possible damsites with more capacity.
5. Test pits along penstock route.
6. Test footing for powerhouse with shallow holes.
-11-
APA10/A
HYDROLOGY
The drainage area above the forebay damsite, as determined from the
U.S.G.S. Kodiak (D-3) and (D-4) 1:63,360 scale maps is 11 square
miles.
The U.S.G.S. established a staff gage in the Port Lions River in 1979.
The first report~d discharge was on June 25, 1979 with a discharge of
15.7 cfs and a gage reading of 4. 00. Two more discharge readings and
gage heights were recorded by U.S.G.S. Additional gage readings were
made through the summer by the City Port Lions. A preliminary discharge
curve plotted from the three discharge readings and all the gage readings
is presented on Figure 3.
These readings are insufficient to use as a guide in estimating the flow
in the Port Lions River for hydroelectric purposes. The readings do
reflect the very dry summer experienced on Kodiak Island in 1979.
Only estimates of the stream flow based on precipitation and runoff data
from nearby watersheds and verified by many years of observation of
stream flow at Port Lions is available.
Extremely small stream flow may occur during extended near-zero weather
or dry periods. Extremely large flows occur in spring, when rain
speeds snow melt, or after heavy rains during the wet months.
Solid rock occurs at shallow depths in the vicinity of Port Lions with
rapid runoff. However, the upper watershed is relatively flat, contains
several lakes, ponds, and peat accumulations in low lying areas, all of
which tends to slow the runoff.
Correlation studies were made with U.S. G. S. readings on Myrtle Creek
situated on the northwesterly side of Cape Chiniak approximately 13 miles
south of the City of Kodiak where rainfall may be expected to be heavier
than at Port Lions. The average annual flow for the 13-years of record
-12-
r
t
l
i
t
i
APA10/A
was 44.9 cfs from a 4. 71 square miles drainage area. Using the ratio
of the two drainage areas and assuming runoff per square mile to be ~
for the Port Lions River, a value of 52.4 cfs was obtained. This was
considered to be extremely high.
Monash ka Creek, situated just northwest of the City of Kodiak and
16 miles east of Port Lions has a precipitation intensity nearer that of
Kodiak than does Myrtle Creek. The U.S.G.S. gaged Monashka Creek
from July 1972 to September 1976 with an average annual flow of 41.75 cfs.
Since the drainage area is ~ that of the Port Lions River and Kodiak
receives nearly twice the annual precipitation, the average monthly
flows of Monashka Creek were applied to the Port Lions River. As
shown on the Monashka Creek recordings included in the Appendix, low
flows may be expected in every month but May and June.
With the exception of December, February and March, storage releases
from Crescent Lake can easily regulate 23 cfs. Crescent Lake can store
approximately 875 acre-feet of water when allowing 2-feet for ice.
During the months of February and March, only 17 cfs can be expected
on the average by drawing from Crescent Lake storage (See Figure 4).
It should be noted that the City of Port Lions has appropriated 3 cfs
from the watershed.

PROJECT DESCRIPTION
Project structures assumed for purposes of estimating costs include a
steel sheet pile forebay dam on Port Lions River, 2,100 feet of 30-inch
steel penstock, two 90 kW turbine-generator sets in a powerplant at
tidewater and a steel sheet pile dam at the mouth of Crescent Lake for
partial regulation of the Port Lions River. Location and details of the
system components are presented on Figure 5 and the large drawings
included in the Appendix.
FOREBAY DAM
The dam (7 feet high with a 240-foot crest length) would be located on
the Port Lions River about 100 feet downstream from the confluence
with Branchwater Creek. The crest elevation of the overflow section
(30-foot in width) was set at elevation 85.0 (2-feet below the non-overflow
sections of the dam), allowing for a spillway capacity of 300 cfs. The
dam would be constructed of 8 gage steel sheeting weighing 9. 3 lbs per
square feet. The sheeting can be handled by two men and pushed into
the ground with vibrator mounted on a backhoe. Steel sheeting would
be driven on each side of the overflow section normal to the axis of the
dam to form a retaining wall for the rock and gravel fill placed around
the sheeting in the non-overflow sections of the dam. The top of the
sheeting would be capped with a 3~-inch angle. The gab ions in the
existing gabion dam would be placed along the downstream toe of the
overflow section to prevent erosion of the stream channel. (See Figure 6).
Sheet pile properties and pricing data are included in the Appendix.

INTAKE WORKS
The overflow section of the dam would be penetrated with a 30-inch
wrought iron pipe with the upstream end flared to reduce the velocity
of approach and a trash rack welded over the opening. A 30-inch
butterfly valve will be installed on the downstream side of the dam.
PENSTOCK
Power flows could be conducted from the dam to the powerplant via a
30-inch diameter smooth pipe or 36-inch diameter galvanized corrugated
\ty'elded pipe with the corrugations running helically. Pipe joints will be
effectively sealed with connecting bands and 0-ring gaskets. The
penstock would be 2100 feet in length and would follow the north bank
of the Port Lions River approximately 500 feet, then northeasterly
approximately 465 feet, then easterly in Tract A through the 13± feet
diameter CMP culvert under the road to the powerhouse on the north
shore of the tidal lagoon near the mouth of the river in Tract B. ·The ·
penstock will be buried or partially buried through most of its length.
Access to the penstock route is readily available at several points as
well as from the existing road to the proposed dam site.
POWERHOUSE
The powerhouse was assumed to be an insulated would frame building at
the 15± feet contour near the mquth of the Port Lions River. The
foundation would be placed on bedrock and the tailrace excavated to
approximate elevation 5 m. s .I. to take advantage of the additional head
created by the fluctuating tide. The powerhouse would contain two
90 kW horizontal reaction type turbine generator units estimated to
operate at 900 RPM under an average net head of 75 feet. A switchyard
would be constructed adjacent to the powerplant. The generator voltage
of 480 would be stepped up to the 7.2/12.5 kV distribution voltage of
the Kodiak Electric Association, Inc.

STORAGE DAM
The storage dam would be located at the mouth of Crescent Lake
approximately three miles west of the powerhouse location. Crescent
Lake has a natural surface area of 140 acres as measured from the
U.S.G.S. Map Kodiak (D-3) Alaska, 1:63360. Present access to the
dam site is by flaatplane or along the Forest Service trail from Part
Lions. The dam would be of similar construction as the farebay dam.
The topography limits the raising of the lake level to about 8 feet.
The dam would be penetrated by a 24-inch diameter drawdawn pipe
approximately three feet in length. The pipe would extend a minimum
of twa feet into the lake with a slide gate an the upstream end. The
gate stem would be of stainless steel or bronze and enclosed in galvanized
pipe filled with ail to prevent the stem from freezing. A flap gate
would be installed an the downstream end to prevent the gate from
freezing when closed. A control weir would be installed immediately
downstream to facilitate the measurement of released water. Construction
materials may be hauled in with a tractor and sled during the winter or
flown in by seaplane or helicopter. Access far water release would be
by snawmachine.

COST ESTIMATES
Construction cost estimate and annual cost estimate for the hydroelectric
generation system described earlier have been prepared. Current bid
prices were used as a data base where possible to estimate the physical
construction costs. Design engineering costs and construction manage-
ment costs were computed as a percentage of the construction estimate.
The design engineering percentage was based on recommendations
contained within the American Society of Civil Engineers Manual 45,
Consulting Engineering, A Guide for the Engagement of Engineering
Services. Construction management percentage was based on past
experience with similar projects. Annual operating costs were based on
the generating capability of the facility. Debt service and interest on
construction money were computed at interest rates and amortization
periods currently being used by lending institutions financing such
construction. It was assumed that all costs would be financed and that
no grant money would be used. It should be noted that legal; land
acquisition; and administrative costs, other than construction management,
were not included in the cost estimates and other computations presented
Tables 2 and 3.
With the rapid increase of fossil fuel prices, the primary benefit in
hydroelectric energy is the fuel cost savings. An estimated cost of fuel
to generate an equivalent amount of electricity during the year 1981
with diesel generators was computed and compared against the total
annual cost for the hydroelectric system. A benefit/cost ratio in favor
of hydroelectric generation developed from this simplified but conservative
comparison. An estimated average cost of hydroelectric power was
computed for 1981. See Table 3.

CONCLUSIONS
T s report indicates a considerable savings in the cost of power from
U Port Lions River in the first year of operation based on current
cc struction prices, 5 percent financing, 35 years payment with the
ic 1tified savings as fuel replacement costs only.
T ~ Port Lions River has the potential of replacing most of the diesel
fL I requirements of Port Lions through the year 2000 if a cannery
ar /or cold storage plant are not constructed. If only a cannery is
cc structed 1 it may not be feasible to intertie Port Lions with the Terror
L< .e Project and all of the potential energy of the Port Lions River
cc lei be utilized. An intertie does appear to be feasible if both a
c.: nery and cold storage plant should be put in operation. If this
sc 1ario becomes a reality 1 the cost of the Port Lions River Project
w1 1ld still be competitive with supplemental diesel generation at the
K l. Kodiak diesel plant.
A 1ough this report identifies the savings as fuel replacement on
ot 2r plus factors should be considered in thf; final analysis of the
pt ject. Some of these pluses are:
1. The effect of inflation on the choice between hydro and thermal
power. An analysis of inflationary effects is presented in an
Article in Water Power & Dam Construction 1 February 1977, page 34
by D. E. Abramowitz. The Corps of Engineers has based some cf
their economic analysis on the work done by Mr. Abramowitz.
2. Lube oil costs.
-25-
APA10/A
3. Variable operation and maintenance costs.
4. The uncertain availability of diesel fuel.
In the Engineer's view, the costs are sufficiently favorable to warrant
detailed investigations, design and construction of the project.

For decades. interlocking steel sheeting from
Armco has been a standard of the construction
industry. Now. Armco introduces Metric Sheet-
with modern metric d1mensions and a new,
efficient configuration that allows an even higher
strength/weight ratio.
Armco Metric Sheeting is a lightweight sheet
piling used by the construction industry to
speed work, provide safer working conditions.
reduce costs. and provide many types of tem-
porary and permanent structures. Lightweight
steel piling serves the industry where heavy
hot-rolled sheeting is impractical, and wooden
sheeting is expensive. cumbersome or struc-
turally inadequate. Typical applications for
Armco Sheeting include shore protection, .
trench protection, low retaining walls. check-
dams. wash checks. jetties, lagoon baffles, and ,
wing walls. .. .. : .. ·
~ Strength-unique corrugated web stiffener
offers highest strength to 'vVeight ratio available.
This efficient design and wide range of availa
gages results in an economical installation.
• Flat Surface-provides a high bearing area
for attaching wales.
• Handling-lightweight Armco Sheeting sim-
plifies transportation, handling, and speeds
installation.
• "Fight Interlock-metal to metal contact
··keeps soil behind the sheeting wall and aids
driving. Its unique design resists pull-apart.
.• o Fast Driving-can be handled by two men
and pushed into ground with a backhoe or
':'driven with a light duty crane in many cases.
,. .. ' '
• Salvagability-pulling holes or clamps
. plify extraction. Voids created are negligible
since Armco Sheeting is less than !4(f thick.
• Storage-nestability enables a large quantity
of sheeting to be stored on the job site or in a
contractor's yard.

Although somelol'hat better sites (higher abutm"nts) are available upstream
on the southern tributary (which probably handles twice.. the flow of the
north tributaTy) the streams are regulated prstty well already by large
lakes. Thus, the need fo"l: a bigger reservoir is decreased. lhe site here,
offers the simplicity of access and the combi.ned flo'ols of both tTibutaries.
Capacity of this reservoiT would be quite 11mall and so the StTeam flows
should be guaged cau•fully to insure that annual fluctuations of Tunoff
would not adventely affect geneTation.
