2012 REVIEW OF EXISTING WATER TEMPERATURE MODEL RESULTS AND DATA COLLECTION
INTRODUCTION
The Alaska Energy Authority (AEA) is preparing a License Application for the proposed Susitna-
Watana Hydroelectric Project (Project), which will be submitted to the Federal Energy
Regulatory Commission (FERC). The licensing is being conducted using the Integrated
Licensing Process (ILP). The proposed Project would be located on the Susitna River, an
approximately 300-mile-long river in the Southcentral region of Alaska. The Project’s dam site
will be located at River Mile (RM) 184. The results of this study and of other proposed studies
will provide information needed to support FERC’s National Environmental Policy Act (NEPA)
analysis for the Project license.
Construction and operation of the Project as described in the Pre-Application Document (PAD,
AEA 2011) will affect flow regimes and water temperatures downstream of the proposed dam
site. This study plan outlines the objectives and methods for reviewing historical 1980s modeling
results and collecting meteorological and stream temperature data that will provide a foundation
for the 2013 and 2014 formal FERC licensing studies.
STUDY OBJECTIVES
The objective of this 2012 WQ-S1 Review of Existing Water Temperature Model Results and
Data Collection Study is to provide a foundation for the 2013-2014 water temperature modeling
study of reservoir and stream temperatures. The specific objectives are as follows:
Evaluate the 1980s water temperature model results and determine the applicability of
the past results to the currently proposed Project.
Initiate collection of stream temperature and meteorological data that will be needed for
the 2013 and 2014 studies.
STUDY AREA
The study area includes the Susitna River within the proposed Watana Reservoir and
downstream of the proposed Watana Dam. Water quality studies will be conducted from river
mile 10.1 (Susitna River above Alexander Creek) to river mile 233.4 (at Oshetna Creek, just
above the upper extent of the proposed reservoir area). The proposed dam would be located at
river mile 184.5. The dam would create a reservoir 39 miles long and up to 2 miles wide, with a
normal reservoir surface area of approximately 22,500 acres and a normal maximum pool
elevation of 2,000 feet.
NEXUS BETWEEN PROJECT AND RESOURCE TO BE STUDIED AND HOW THE RESULTS WILL BE USED
The Project's operations will modify the flow and water temperature in the Susitna River
downstream of the proposed reservoir. Reservoir operation and storage levels will affect water
temperature in the reservoir and influence outflow water temperatures. Alteration of the water
temperature in the Susitna River could modify river ice conditions, which in turn could impact
channel morphology and riparian vegetation, as well as the suitability and productivity of aquatic

habitats. This could include the lower river, which is the habitat of forage fish for Cook Inlet
beluga whales.
The results of the 2012 study will be used to further develop plans for additional studies in 2013-
2014, assess effects of the proposed Project, and to identify protection, mitigation, and
enhancement (PME) measures in the reservoir and in Project-affected river reaches
downstream of the dam.
This study addresses some aspects of the following issues identified in the PAD (AEA 2011) for
which existing information appears to be insufficient:
WQ-S2: Potential effects of reservoir filling, Project operations, including reservoir surface
elevation fluctuations, on temperature, turbidity, total dissolved/suspended solids,
dissolved oxygen, pH, metals, and chemical/nutrient (fecal coliform, total phosphate,
soluble reactive phosphorus, total nitrogen, ammonia nitrogen, nitrate+nitrite-nitrogen)
characteristics within the reservoir.
WQ-S3: Potential effect of Project operations on temperature, turbidity, total
dissolved/suspended solids, dissolved oxygen, pH, metals, and chemical/nutrient (fecal
coliform, total phosphate, soluble reactive phosphorus, total nitrogen, ammonia nitrogen,
nitrate+nitrite-nitrogen) characteristics of the mainstem river downstream from the
proposed Susitna-Watana Dam Site (RM 184).
EXISTING INFORMATION
Stream temperature data were collected in the mainstem Susitna River during the 1980s. These
data were used both as input values and calibration data for the 1980s stream water
temperature model (Stream Network Temperature Model [SNTEMP]; Theurer et al. 1984) and
reservoir water temperature model (Dynamic Reservoir Simulation Model [DYRESM]); Imberger
and Patterson 1981). SNTEMP is a one-dimensional river water temperature model. DYRESM
is a one-dimensional hydrodynamics model used to predict the vertical distribution of
temperature and density in lakes and reservoirs.
Results from the 1980s water temperature modeling studies are contained in the reports listed
in Table 1. These reports are available digitally at the Alaska Resources Information and Library
Service (ARLIS).

Susitna Hydroelectric Project Stream Temperature Reports
Additional data sources were reviewed prior to preparation of this study as part of the Water
Quality and Sediment Transport Data Gap Analysis Report (URS 2011). The data gap analysis
report focused on summarization and evaluation of existing data for use in the Susitna-Watana
FERC license application. Technical information used for the evaluation was collected over the
past 30 years, with most water quality information (e.g., conventional parameters and metals)
being more than 20 years old. The results of the data gap analysis indicated that elevated
surface water temperatures periodically occur in important salmonid spawning and migration
habitat and that more current temperature data would be useful for verifying previous
temperature exceedances and describing the extent of temperature issues.
METHODS
SAP and QAPP
A Sampling and Analysis Plan (SAP) and a Quality Assurance Project Plan (QAPP) will be
prepared as part of implementation of this 2012 study plan. The SAP and QAPP are standard
documents prepared before any water quality sampling and model development begins. These
documents follow guidelines for the State of Alaska and U.S. Environmental Protection Agency
Region 10 Credible Data Policy (ADEC 2005).
Evaluate 1980s Water Temperature Modeling Results
The 1980s SNTEMP and DYRESM model results will be evaluated to determine the applicability
of the results to the current proposed Project for the purpose of guiding the development of the
2013-2014 study plans (e.g., water quality, fish, ice processes, instream flow, and productivity).
a. SNTEMP and DYRESM predictive capabilities and associated assumptions will be
evaluated to determine if the model results are appropriate for application to current
conditions and the proposed Project. Any critical limitations will be identified.
b. The models’ general configurations, input parameters, and quality of
calibration/validation will be evaluated. The accuracy of representation for current and
proposed conditions will be ascertained.

c. 1980s river flows and release schedules will be analyzed and compared to recent
records to determine the applicability of these historic flow and release data to the
currently proposed Project.
d. If the existing temperature models and results are applicable to the currently proposed
Project, results will be synthesized to evaluate the potential effects of the proposed
Project on water temperature and guide the design of the 2013-2014 study plans.
e. Coordination with other resource studies (e.g., water quality, ice processes, fish,
instream flow, productivity) will occur to assist in developing 2013-2014 study plans that
appropriately anticipate potential water temperature effects of the proposed Project.
Water Temperature Data Collection
Overview
Water temperature data and monitoring locations from the 1980s (Figure 1) have been
evaluated to determine which of the historic locations should be monitored for the 2012 study.
Locations were evaluated based on (1) adequate representation of locations throughout the
Susitna River and tributaries above and below the proposed dam site; (2) preliminary
consultation with AEA and licensing participants; and (3) anticipation of other studies and study
sites (e.g., instream flow, ice processes). Characterization of water temperature will be
completed in a variety of riverine locations. Fish habitat permit applications will be prepared for
submittal to Alaska Department of Fish and Game (ADFG) that include temperature monitoring
station design and will be reviewed by the Habitat Division in Palmer, AK.
Water temperature data loggers will be installed at 39 sites (Table 2, Figure 2). Eight of the sites
are mainstem monitoring sites that were previously used for SNTEMP modeling (1980s). Thirty-
one of the sites are mainstem, tributary, or slough locations, most of which were monitored in
the 1980s. Locations for sites are suggested for several reasons: 1) they provide good
coverage of the mainstem for temperature modeling, 2) they provide coverage in areas of
important fish habitat, 3) sites represent the influence of major tributaries that may influence
thermal refugia downstream, and 4) the sites extend an existing data record beginning from the
1980s to the present to determine if conditions have changed and how this impacts thermal
refugia under current conditions.

Installation and Monitoring Protocol
Water temperatures will be recorded at 15-minute intervals using Onset TidbiT® v2 water
temperature data loggers (or equivalent instrumentation). The TidbiT v2 (or equivalent) has a
precision sensor for ±0.2°C accuracy over an operational range of -20°C to 70°C (-4°F to
158°F). Data readout is available in less than 30 seconds via an Optic USB interface.
Temperature probe calibration forms and field deployment forms are located in Appendix A.
To reduce the possibility of data loss, a redundant data logger will be used at each site. In
general, two sets of sensors will be installed in different fashions (depending on site
characteristics). One logger will be inserted into the bottom of a 2.5-meter (8.2-foot) length of
perforated steel pipe housing fastened to a large bank structure via clamps and rock bolts. The
TidbiT (or equivalent instrument) will be attached to a rope that will allow it to be easily retrieved
for downloads. The top pipe cap will contain a locking mechanism, which can only be opened
using the appropriate Allen key to prevent theft or vandalism. The second set of temperature
loggers will be anchored to a concrete block and buoyed so that bottom, mid, and surface
loggers record continuous temperature conditions throughout the water column (fewer
temperature loggers may be deployed depending on site characteristics). The block will be
placed in a location of the channel that is accessible and retrievable during routine site visits,
and the apparatus will be attached with a steel cable to a post driven into the bank or to some
other structure. The proposed installation procedures may require some alteration based on site
specific conditions.
The sensors will be situated in the river to record water temperatures that are representative of
the mainstem or slough being monitored, avoiding areas of groundwater upwelling, unmixed
tributary flow, direct sun exposure, and isolated pools that may affect the quality of the data.
The 2012 River Flow Routing Model Data Collection study will install water-level loggers with
temperature recording capability at up to 12 of the temperature monitoring sites. A redundant
string of TidbiT v2 temperature loggers (measuring bottom, mid, and surface conditions) will be
deployed at these sites to complement the full deployment of equipment installed at all other
temperature monitoring sites.
Meteorological Data Collection
Overview
Meteorological (MET) data collection will be initiated, and MET stations will be installed and/or
upgraded at up to eight (8) locations between RM 224 and RM 25.6 during 2012. Table 3 lists
the MET station locations. The exact spatial location will depend on access and suitability of an
appropriate site for installing a MET station.

The two MET stations near the Watana Dam site need to be established at specific locations as
requested by Project design engineers. The upland MET station will be established at about the
2,300 foot elevation on the north side of the river, in the area of the proposed field camp. The
upland MET station will record snowfall data and precipitation. The near riversite MET station
will be located on the north abutment just above river level, depending on suitability of location
for establishing the structure.
Existing meteorological stations will be fitted with additional monitoring equipment and expand
data collection to meet Project needs and to use historical information collected from each of
these sites (Table 3). The linkage between historical records and continuing data records may
be used in evaluating the utility of 1980s temperature data for modeling.
MET Station Parameters
MET stations are required to collect several types of parameters that will be used by the
engineering design team for the proposed dam and will be used to provide inputs to the water
quality model. The following is a comprehensive list of parameters required for use in this
Project and will be measured continuously by each of the MET stations:
Temperature – maximum, minimum, mean
Relative humidity
Barometric pressure
Precipitation
Wind speed – maximum, minimum, mean
Wind direction

2012 Review of Existing Water Temperature Model Results and Data Collection, May 2, 2012 Page 10
Wind gust – maximum
Wind gust direction
Solar degree days
Installation and Monitoring Protocol
Each MET station will consist of, at a minimum, a 3-meter tripod with mounted monitoring
instrumentation to measure and record wind speed and direction, air temperature, relative
humidity, barometric pressure, incident solar radiation, and water-equivalent precipitation in 15-
minute intervals (Figure 3). The station loggers will have sufficient ports and programming
capacity to allow for the installation of instrumentation to collect additional meteorological
parameters as required. Such installation and re-programming can occur at any time without
disruption of the data collection program.
Figure 3. Example Meteorological Station Installation
MET station installation is intended to provide instrumentation that is sturdy enough to work
continuously, with little maintenance, and produce high quality data through a telemetry system.
A Campbell Scientific CR1000 data logger will be used to record data. The archiving interval for
all meteorological parameters will be 15 minutes, with a storage capacity to log up to two (2)
years of data before filling the memory. The MET station will be powered by a 12 Vdc 8 amp-
hour battery and a 20-watt solar panel with charge regulator.
To protect the stations from wildlife intrusion and to discourage any potential vandalism the
stations will be protected by fencing as appropriate.

2012 Review of Existing Water Temperature Model Results and Data Collection, May 2, 2012 Page 11
Satellite or Radio Telemetry Communications System
Real-time data will be downloaded from the data logger using satellite transmission or radio
telemetry hardware. This will enable study staff to download, inspect, and archive data and
monitor station operational parameters for signs of problems without visiting the site. The
communication will ensure that problems, if they occur, are resolved promptly so that minimal
data will be lost between service periods.
Conduct a Pilot Thermal Imaging Assessment of a Portion of the Susitna River
Aerial infrared photography and imagery have been used to locate areas of active groundwater
discharge to surface waters (Robinove, 1965; Fischer and others, 1966; Robinove and
Anderson, 1969; Taylor and Stingelin, 1969). This technique is effective only if the temperatures
of surface water and groundwater differ by at least 2 °C (Pluhowski, 1972; Rundquist and
others, 1985; Banks and others, 1996). Such a differential typically occurs on the Susitna River
only during brief time periods in the fall and spring. The period for detecting this difference may
be too small to exploit.
If areas of active groundwater recharge to surface water could be identified using aerial infrared
imagery, it would provide valuable insights into evaluating water quality, and may help identify
areas where salmon overwintering occurs. It would allow for rapid and accurate identification of
gaining reaches over large areas that cannot be accomplished by stream surveys that measure
temperature directly (Pluhowski, 1972). It may also allow AEA to obtain data for portions of the
river where direct temperature measurements are impractical or access is dangerous.
Because of the potential value, AEA has decided to test this technique on a portion of the
Susitna River, and if it works, to use it on other sections as well. Thermal imagery data from 10
miles of the Middle River will be collected. Data from the thermal imagery will be ground-truthed,
and the applicability and resolution of the data will be evaluated in terms of identifying water
temperatures and thermal refugia/upwelling. In coordination with the Instream Flow and fish
studies, a determination will be made as to whether additional thermal imaging data will be
applicable and whether or not additional thermal imaging will be collected during the 2013 field
season to characterize river temperature conditions.
If the pilot study is successful, then a description of thermal refugia throughout the project
vicinity can be mapped using aerial imagery calibrated with on-the-ground verification. The
verification data will be collected at the same time as the aerial imagery (or nearly the same
time) using the established continuous temperature monitoring network and additional grab
sample temperature readings where there may be gaps, such as in select sloughs.
The following elements are important considerations for data collection, specifications for data
quality, and strategy for relating digital imagery and actual river surface water temperatures.
Radiant Temperature
Remotely sensed thermal images allow for spatially distributed measurements of radiant
temperatures in the river.
Radiant temperature measurements are made only on the surface layer of the water (top
10 cm).
Temperature readings can vary depending on the amount of suspended sediment in the
water and the turbidity of the water.
Spatial Resolution
The key to good data quality is determining the pixel size of the TIR sensor and how that
relates to the near-bank environment.
Susitna-Watana Hydroelectric Project FERC #14241 Alaska Energy Authority
2012 Review of Existing Water Temperature Model Results and Data Collection, May 2, 2012 Page 12
Best practice is 3 pure-water pixels (ensures that the digital image represented by any 3
contiguous pixels identifies water versus land).
Very fine resolution (0.2 - 1 m) imagery is best used to determine groundwater springs
and cold-water seeps.
Larger pixels can be useful for determining characteristic patterns of latitude and
longitude thermal variation in riverine landscapes.
Calibrating Temperature
Water temps change during the day; therefore collection should be measured near the
same time daily and when water temp is most stable (early afternoon).
Validation sampling site selections are determined where there is channel accessibility
and where there are no known influences of tributaries or seeps in the area.
Hand-held ground imaging radiometers can provide validation as long as the precision is
at least as good as that expected from airborne TIR measurements.
Availability of historical imagery for thermal analysis will also be investigated.
STUDY PRODUCTS
Study products to be delivered in 2012, at a minimum, will include:
Interim Technical Memorandum. An interim report describing the 1980s data, models, and reports
that were recoverable; a statement regarding the applicability of the recovered work to the
current project; and recommendations regarding additional study needs to be addressed in
2013 - 2014 will be prepared. Locations of meteorological stations and thermographs installed in
2012 will be reported in ArcGIS. All map and spatial data products will be delivered in the two-
dimensional Alaska Albers Conical Equal Area projection, and North American Datum of 1983
(NAD 83) horizontal datum, consistent with Alaska Department of Natural Resources (ADNR)
standards.
Geo-spatially Referenced Relational Database. All historic data used in the analysis and data
collected during the 2012 field season, including links to photographs, will be checked for quality
and delivered in a geospatially-referenced relational database to AEA. This database will form
the basis for additional data collection in 2013 - 2014. All field data must be associated with
location information collected using a Global Positioning System (GPS) receiver in unprojected
geographic coordinates (latitude/longitude) and the WGS84 datum. Naming conventions of files
and data fields, spatial resolution, and metadata descriptions must meet the ADNR standards
established for the Susitna-Watana Hydroelectric Project.
Technical Memorandum. A technical memorandum summarizing the 2012 results will be
prepared and presented to resource agency personnel and other licensing participants, along
with spatial data products.
