On September 15, 2009, the Federal Energy Regulatory Commission (FERC) approved the use of the Traditional Licensing Process (TLP) for development of the License Application (LA) and supporting materials. Per the TLP, KHL underwent consultation with the requisite stakeholders in relation to the development of a series of natural resource studies that were completed in 2013. As described in more detail below, the proposed Project has been modified to eliminate the diversion of water from Falls Creek to Grant Lake. The Aquatic Resources Study Plan was designed to address information needs identified in the PAD, during the TLP public comment process, and through early scoping conducted by FERC. This report specifically addresses the Instream Flow Study, one of the components to the Aquatic Resources investigations. Information from this report will be used to analyze flow-related Project impacts and to propose protection, mitigation, and enhancement (PM&E) measures. 1.1. Proposed Project Description The Project is located near the community of Moose Pass, Alaska, approximately 25 miles north of Seward and just east of the Seward Highway. It lies within Section 13 of Township 4 North, Range 1 West; Sections 1, 2, 5, 6, 7, and 18 of Township 4 North, Range 1 East; and Sections 27, 28, 29, 31, 32, 33, 34, 35, and 36 of Township 5 North, Range 1 East, Seward Meridian (U.S. Geological Survey [USGS] Seward B-6 and B-7 Quadrangles). The proposed Project would be composed of an intake structure at the outlet to Grant Lake, a tunnel, a surge tank, a penstock, and a powerhouse. It would also include a tailrace detention pond, a switchyard with disconnect switch and step-up transformer, and an overhead or underground transmission line. The preferred alternative would use approximately 15,900 acre- feet of water storage during operations between pool elevations of approximately 692 and up to 703 feet North American Vertical Datum of 1988 (NAVD 88)1. 1 The elevations provided in previous licensing and source documents are referenced to feet mean sea level in NGVD 29 [National Geodetic Vertical Datum of 1929] datum, a historical survey datum. The elevations presented in the Grant Lake natural resources study reports are referenced to feet NAVD 88 datum, which results in an approximate +5-foot conversion to the NGVD 29 elevation values. FINAL REPORT AQUATIC RESOURCES – HABITAT MAPPING / INSTREAM FLOW STUDY Grant Lake Hydroelectric Project Kenai Hydro, LLC FERC No. 13212 2 June 2014 An intake structure would be constructed approximately 500 feet east of the natural outlet of Grant Lake. An approximate 3,200-foot-long, 10-foot diameter horseshoe tunnel would convey water from the intake to directly above the powerhouse at about elevation 628 feet NAVD 88. At the outlet to the tunnel, a 360-foot-long section of penstock will convey water to the powerhouse located at about elevation 531 feet NAVD 88. An off-stream detention pond will be created to provide a storage reservoir for flows generated during the rare instance when the units being used for emergency spinning reserve are needed to provide full load at maximum ramping rates. The tailrace would be located in order to minimize impacts to fish habitat by returning flows to Grant Creek upstream of the most productive fish habitat. Two concepts are currently being evaluated for water control at the outlet of Grant Lake. The first option would consist of a natural lake outlet that would provide control of flows out of Grant Lake. A new low-level outlet would be constructed on the south side of the natural outlet to release any required environmental flows when the lake is drawdown below the natural outlet level. The outlet works would consist of a 48-inch diameter pipe extending back into Grant Lake, a gate house, regulating gate, controls, and associated monitoring equipment. The outlet would discharge into Grant Creek immediately below the natural lake outlet. In the second option, a concrete gravity diversion structure would be constructed near the outlet of Grant Lake. The gravity diversion structure would raise the pool level by a maximum height of approximately 2 feet (from 703 to 705 feet NAVD 88), and the structure would have an overall width of approximately 120 feet. The center 60 feet of the structure would have an uncontrolled spillway section with a crest elevation at approximately 705 feet NAVD 88. Similar to the first option, a low-level outlet would be constructed on the south side of the natural outlet to release any required environmental flows when the lake is drawn down below the natural outlet level. The outlet works would consist of a 48-inch diameter pipe extending back into Grant Lake, a gate house, a regulating gate, controls, and associated monitoring equipment. The outlet would discharge into Grant Creek immediately below the diversion structure. Figure 1.1-1 displays the global natural resources study area for the efforts undertaken in 2013 and 2014 along with the likely location of Project infrastructure and detail related to land ownership in and near the Project area. Further discussions related to specifics of the aforementioned Project infrastructure along with the need and/or feasibility of the diversion dam will take place with stakeholders in 2014 concurrent with the engineering feasibility work for the Project. Refined Project design information will be detailed in both the Draft License Application (DLA) and any other ancillary engineering documents related to Project development. The current design includes two Francis turbine generators with a combined rated capacity of approximately 5.0 megawatts (MW) with a total design flow of 385 cubic feet per second (cfs).

FINAL REPORT AQUATIC RESOURCES – HABITAT MAPPING / INSTREAM FLOW STUDY Grant Lake Hydroelectric Project Kenai Hydro, LLC FERC No. 31212 5 June 2014 1.2. Existing Information Information relating to aquatic resources has been collected during previous investigations into the potential development of hydroelectric generation on Grant Lake as well as during pre- licensing studies conducted by KHL in 2009 and early 2010. Previous FERC licensing efforts in the 1960s and 1980s for a proposed hydroelectric project at Grant Lake included studies of fish resources in Grant Lake and Grant Creek. Arctic Environmental Information and Data Center (AEIDC 1983) conducted fish sampling from 1981 to 1982 as part of a comprehensive environmental baseline study effort, and the U.S. Fish and Wildlife Service (USFWS 1961) conducted limited sampling from 1959 to 1960. An Instream Flow Study was completed in 1987 as part of a preliminary FERC LA prepared by Kenai Hydro, Inc. (KHI; not related to the current Kenai Hydro, LLC; Envirosphere 1987, KHI 1987a, and KHI 1987b). This effort included reports and written communications between KHI and state and federal agencies in 1986 and 1987 relative to a FERC LA for the proposed Grant Lake Hydroelectric Project (FERC No. 7633-002). Included were draft and final reports of a limited but complete Instream Flow Incremental Methodology (IFIM) investigation and negotiated minimum instream flows and ramping rates (Envirosphere 1987, KHI 1987a, and KHI 1987b). The collaborative process for a study of “instream flow” effects in Grant Creek was initiated in 2009 (HDR 2009a). The primary goal of the 2009 Instream Flow Study program was to establish a Technical Working Group (TWG) consisting of state and federal resource agency staff, KHL staff, and interested members of the local community. Once established, the TWG met three times during the 2009 study season to review the results of the 2009 aquatic baseline study efforts, discuss and agree upon an acceptable instream flow evaluation method, and request additional information to support that selection (HDR 2009a). A technical memorandum was drafted and shared with the Instream Flow TWG participants in 2009 detailing the results of the previous Instream Flow Study efforts (HDR 2009b). As part of the Instream Flow Study, and at the request of the TWG, a sampling event was conducted June 23–25, 2009 on Grant Creek to characterize the types of aquatic habitats used by resident fish and rearing fish (HDR 2009a). Aquatic habitat was described at each sample site by recording macro-, meso-, and micro-habitat characteristics. During the June sampling event, snorkeling was the primary method used to document fish presence. Electrofishing was used primarily to confirm species identification and calibrate fish length estimates (HDR 2009a). Collaboratively, the TWG and KHL decided to select an Instream Flow Study methodology based on the knowledge obtained from the summer 2009 aquatic resources and hydrology studies (HDR 2009a). Data and analyses from these studies were shared with the TWG in July and September. Based on the knowledge gained of Grant Creek’s fish and hydrologic resources, KHL presented a proposed instream flow approach to the TWG on September 23 (HDR 2009a). Physical stream data required for instream flow modeling, per the proposed approach, were collected at 18 transects during low- and mid-flow conditions in 2010. Where applicable, these data were used in the 2013 Instream Flow Study. FINAL REPORT AQUATIC RESOURCES – HABITAT MAPPING / INSTREAM FLOW STUDY Grant Lake Hydroelectric Project Kenai Hydro, LLC FERC No. 13212 6 June 2014 2 STUDY OBJECTIVES 2.1. Overall Goals Identified during Project Scoping Together with existing information, the goals of the study efforts were to provide baseline information, and where applicable, information on alternative flow regimes, which would allow an assessment in the study report of potential Project impacts on aquatic resources. These impact assessments are used to identify potential PM&E measures. The goals of this suite of studies were to provide supporting information on the potential resource impacts of the proposed Project that were identified during development of the PAD, public comment, and FERC scoping for the LA, as follows: Impact of Project operation on sediment transport (relative to the availability of spawning gravels) due to changes in flow in Grant Creek. Impact of Project operation (fluctuating lake levels in Grant Lake, changes in seasonal flow in Grant Creek, reduced flows between the dam and powerhouse on Grant Creek). 2.2. Specific Goals of Aquatic Habitat Mapping Prepare a geospatially referenced image of Grant Creek upon which aquatic habitat and fish use information can be superimposed. Develop a map of aquatic habitats that will provide a basis for describing the distribution of key habitat types. Identify important factors that influence fish use of key habitats for input to the instream flow analysis. Identify and map habitat with sufficient resolution so that the geographic information system (GIS) can be used to accurately calculate surface areas. 2.3. Specific Goals of the Instream Flow Study Assist impact analysis by modeling changes in key types of fish habitat relative to potential changes in stream flow. Provide a basis for planning Project instream flow mitigation measures. Provide a starting point for stream flow discussion. Provide supportable predictions of fish habitat availability in lower Grant Creek under various stream flow scenarios for key species and life history stages. Assess connectivity of the habitats present in Reach 5 (i.e., the Canyon Reach) to determine if reductions in stream flow in this reach potentially affect habitat connectivity. The purposes of this study were to fully delineate and map the aquatic habitats available in Grant Creek, identify important spawning and rearing fish habitats for both resident and anadromous salmonids, and describe the distinguishing factors that may influence fish use of the key habitats over those habitat units not occupied by fish in Grant Creek. FINAL REPORT AQUATIC RESOURCES – HABITAT MAPPING / INSTREAM FLOW STUDY Grant Lake Hydroelectric Project Kenai Hydro, LLC FERC No. 13212 7 June 2014 3 STUDY AREA The Project area is located near the town of Moose Pass, Alaska (population 206), approximately 25 miles north of Seward, Alaska (population 3,016), just east of the Seward Highway (State Route 9); this highway connects Anchorage (population 279,671) to Seward. The Alaska Railroad parallels the route of the Seward Highway and is also adjacent to the Project area. The town of Cooper Landing is located 24 miles to the northwest and is accessible via the Sterling Highway (State Route 1), which connects to the Seward Highway approximately 10 miles northwest of Moose Pass. Grant Creek is approximately 5,180 feet long (about one mile) and flows west from the outlet of Grant Lake to the narrows between Upper and Lower Trail lakes (Figure 3.0-1). The Grant Creek watershed is approximately 44 square miles and the watershed contains Grant Lake as well as a portion of the Kenai Mountain Range, with glacier-capped peaks as high as 5,500 feet. Grant Creek has a mean annual flow of 193 cfs, with an average gradient of 207 feet per mile; its substrate includes cobble and boulder alluvial deposits and gravel shoals (Ebasco 1984). In its upper half, Grant Creek passes through a rocky gorge with three substantial waterfalls (i.e., the break between Reaches 5 and 6); in its lower half, the stream becomes less turbulent as it passes over gravel shoals and diminishing boulder substrate (Ebasco 1984). For the purposes of the Grant Creek Instream Flow Study, the study area extends from the upstream border of Reach 5 downstream to the confluence of Grant Creek with the Trail Lakes. The study area includes only Grant Creek and its associated habitats (i.e., edge and mid-channel, main and side channels). This study area does not encompass the high water overflow channel, located between Reaches 1 and 2. 4 METHODS This section provides methods for both the Grant Creek aquatic habitat mapping and the Instream Flow Study in Sections 4.1 and 4.2, respectively. Further details can be found in the Aquatic Resources Study Plan (KHL 2013). 4.1. Grant Creek Aquatic Habitat Mapping The approach of this study involved three primary phases. During the first phase, the team spatially synthesized existing aquatic habitat and fish use data generated during various field efforts throughout the 2009 and 2010 field seasons. This exercise was completed primarily to identify spatial data gaps. In the second phase, the team then ground-truthed habitat data in the field, collected additional habitat and fish use data in Reaches 1 through 5, and incorporated other suitable habitat and fish use data collected in 2010 (e.g., Instream Flow Study). Finally, the team analyzed the suite of habitats and fish use data to identify important factors affecting distribution of fish. The primary tasks associated with this approach were as follows: Preparation of an office-based aquatic habitat map (i.e., based on habitat observations assembled throughout the 2009 and 2010 field seasons). FINAL REPORT AQUATIC RESOURCES – HABITAT MAPPING / INSTREAM FLOW STUDY Grant Lake Hydroelectric Project Kenai Hydro, LLC FERC No. 13212 8 June 2014 Field surveys to ground-truth the office-based mapping effort and fill spatial data gaps relative to aquatic habitat and fish use in Reaches 1 through 4. Actual collection of fish habitat use information was accomplished by the resident and rearing fish tasks discussed in the Fisheries Report and the instream flow task. Incorporated aquatic habitat fish use data that identified key rearing, spawning, and feeding habitats for salmon and resident fish and potential overwintering habitats. Analyzed and identified the factors that may influence fish use of the key habitats over those habitat units not occupied by fish in Grant Creek. The office-based mapping exercise incorporated existing habitat data overlain by fish use data into a spatial format, using ArcMap© GIS software. The initial dataset included habitat units mapped during a microhabitat fish use reconnaissance study completed in June 20092. The team plotted locations of salmon spawning activity recorded during 2009 foot surveys and high-use spawning areas identified by historical data (Ebasco 1984). The teams used the preliminary spatial fish habitat information to catalog and identify gaps in coverage. The team conducted surveys to ground-truth the preliminary aquatic habitat delineation (i.e., generated through the office-based exercise), redraw mapping boundaries where appropriate, and confirm the location of habitat areas that are in need of additional study. The team delineated aquatic habitats at the mesohabitat level and subcategory scale, consistent with the approach developed for the approved 2009 habitat reconnaissance study. The team identified key fish habitats in Grant Creek, based on observed fish use. This was accomplished by analyzing the microhabitat fish use data collected in support of the habitat mapping study, data collected in support of the Instream Flow Study, and data collected in 2009 during the reconnaissance study (HDR 2009a). These data were incorporated into the spatial dataset. Other fish use habitat datasets (e.g., foot surveys, telemetry surveys, electrofishing) were considered when developing key habitat designations. Surface areas of habitat types were calculated as needed using the capability of the GIS software. Definition of Terms Mesohabitat types were identified and mapped in 2009/2010. The following definitions are provided for these habitat types (Overton et al. 1997, unless otherwise noted): Backwater: Pool formed by an eddy along a channel margin downstream from obstructions such as bars, rootwads, or boulders, or resulting from back-flooding upstream from an obstructional blockage. Also, a body of water, the stage of which is controlled by some feature of the channel downstream from the backwater, or in coves or covering low-lying areas and having access to the main body of water. 2 The 2009 fish microhabitat use reconnaissance study was initiated to gain insight into the types of habitats that fish occupy in Grant Creek. The team identified discrete microhabitat types and sampled for fish presence at 16 sites in Grant Creek.

These are categorized as singles, aggregates, or root wads. is different than criteria for AK]. ○ Aggregate: Two or more clumped pieces, each of which qualifies as a single piece. ○ Rootwad: Root mass or boles attached to a log less than 3 m in length. Pocket: Small bed depressions, often less than 30 percent of wetted width, formed around channel obstructions (boulders, logs, irregular bank, jutting peninsulas, and so forth) within fast water habitat types. Pool: A habitat type formed by either scour that has carved out a depression in the channel, or a location where the channel has been dammed. Surface velocities may be slow to fast, but subsurface velocities tend to be slow. Pools are characterized by a head crest (upstream break in slope) and a tail crest (downstream break in slope). Types of pools include the following: ○ Dammed: Pool formed by downstream damming action. Dam pools can be located in the main channel (or side channel) or backwaters. ○ Scour: Pool formed by scour action when flowing water impinges against and is diverted by a streambank or channel obstruction (rootwad, woody debris, boulder, bedrock, and so forth). Scour pools may be lateral scour, mid-scour, plunge, or underscour pools. ○ Lateral scour: A pool formed by the scouring action of the flow as it is directed laterally or obliquely to one side of the stream by a partial channel obstruction, such as a gravel bar or wing deflector, or by a shift in channel direction. ○ Mid-channel scour: A pool formed by the scouring action of the flow as it is directed toward the middle of the channel by a partial channel obstruction. ○ Plunge: A pool formed by scouring action from vertically falling water. ○ Underscour: A pool formed by scouring under an obstruction, such as a log. Sometimes called an upsurge pool. Riffle: Shallow rapids where the water flows swiftly over completely or partially submerged obstructions to produce surface agitation, but where standing waves are absent. FINAL REPORT AQUATIC RESOURCES – HABITAT MAPPING / INSTREAM FLOW STUDY Grant Lake Hydroelectric Project Kenai Hydro, LLC FERC No. 13212 12 June 2014 Side channel: A lateral channel with an axis of flow roughly parallel to the mainstem and which is fed by water from the mainstem; a braid of a river with flow appreciably lower than in the main channel. Slow water: Habitat types consist of dammed (main and backwater) and scour (lateral, mid-channel, plunge, and underscour). Stream margin: edge of the wetted perimeter. Undercut bank: A bank that has its base cut away at least 5 centimeters (cm) by the water or has been artificially made and overhangs directly above the water surface. 4.2. Grant Creek Instream Flow Study The Grant Creek Instream Flow Study approach to be applied to lower Grant Creek Reaches 1–4 was collaboratively developed based on input from the Instream Flow TWG. Public meetings of the TWG were held in April and September 2009, and a conference call was held in May 2009; input and suggestions were solicited during these meetings and also through e-mail and phone communications with the TWG and TWG members. Subsequently, KHL met with the stakeholders in December 2012 to update study plans and to prepare for the 2013 field season. As agreed to during the previous 2010 investigations, the selected Instream Flow Study approach emphasized a detailed study of utilized habitat types and addressed the desire of the TWG to examine how important individual habitat units may be affected by changes in flow due to the operation of the Project. Rather than applying a typical habitat study that generalized mesohabitat units in a study reach, the agreed-upon approach used several techniques to tie physical microhabitat to flow and timing, and applied in situ knowledge of fish habitat use in Grant Creek as tools to determine potential effects of the Project. The selected approach included the following: A series of single transect analyses, with each transect going through a known fish use area such as high-use spawning or rearing areas. Fish studies that helped identify microhabitat factors that affected fish use within each key habitat type. Monitoring temperature and flows at multiple locations in Grant Creek in conjunction with the Water Resources study program to establish baseline stream flow and temperature changes. The 2013 Instream Flow Study built upon the investigations that began in 2009. The following sections describe methods used for the various components to complete the instream flow assessment. 4.2.1. Overview of Physical Habitat Simulation (PHABSIM) Methodology The instream flow methodology is based on the premise that stream-dwelling fish are more often found in a certain range of depths, velocities, substrates, and cover types, depending upon the species and life stage, and that the availability of these preferred habitat conditions varies with stream flow. Physical Habitat Simulation (PHABSIM) is designed to quantify potential physical FINAL REPORT AQUATIC RESOURCES – HABITAT MAPPING / INSTREAM FLOW STUDY Grant Lake Hydroelectric Project Kenai Hydro, LLC FERC No. 13212 13 June 2014 habitat available for each target fish species and life stage of interest, at various levels of stream discharge, using a series of modeling programs initially developed by the U.S. Fish and Wildlife Service (USFWS). Major components of the methodology include (1) study site and transect selection; (2) transect weighting; (3) field collection of hydraulic data; (4) hydraulic simulation to determine the spatial distribution of combinations of depths and velocities with respect to substrate and cover under a variety of discharges; and (5) habitat simulation, using habitat suitability criteria (HSC) to generate an index of change in habitat relative to change in discharge. The product of the habitat simulation is expressed as weighted usable area (WUA) for a range of simulated stream discharges. It is important to recognize that the product of an instream flow analysis is not a set value, but rather is a range of values to be used as a tool for discussing and determining a range of stream flows that will meet the needs of the affected resources. 4.2.2. Habitat Availability and Transect Selection The purpose of the habitat availability component of the Instream Flow Study was to measure available habitat at proposed mesohabitat sites as a function of discharge (Table 4.2-1). Available habitat was correlated to results of the habitat utilization component described in Section 4.2.3. This information was cross-referenced with historic hydrographs, recent hydrologic data, and potential flow scenarios in Grant Creek to determine discrete time periods when the habitat unit may be available for its designated use. Cross section geometry, substrate, cover, and hydraulic data were measured at each transect using techniques developed for PHABSIM. Application of PHABSIM techniques on Grant Creek is different from most other studies because transects were selected on important habitat units with known fish use, as opposed to a standard PHABSIM approach that attempts to represent all habitat units regardless of unique importance or known fish use.

Survey instrument and photo points were established and marked. Each transect site was fixed using a handheld Global Positioning System (GPS). Habitat unit cross sectional profiles were surveyed using standard differential survey techniques. Cross section survey points divided the profile into 1 – 3 foot cells, depending upon changes in elevation, substrate, or hydraulic conditions. Dominant and subdominant substrate and cover were recorded within each cell. Water surface elevations (WSE) at each transect were measured using a survey instrument at 3 to 5 discharges in the mainstem of Grant Creek, ranging from a low flow of approximately 17 cfs to FINAL REPORT AQUATIC RESOURCES – HABITAT MAPPING / INSTREAM FLOW STUDY Grant Lake Hydroelectric Project Kenai Hydro, LLC FERC No. 13212 15 June 2014 a high flow of approximately 700 cfs. WSE were measured at 3 – 4 discharges in the side channels, ranging from a low flow of 1.4 cfs to a high flow of approximately 114 cfs. Mean column velocities were measured within each cell at a high flow of 170 to 200 cfs (as measured at the Grant Creek stream gage), or the highest possible flow within practical and safety limitations. Numerous photos from established photopoints were taken at each of the 3 to 5 flow levels. Cross sections (Table 4.2-1) were located during a site visit on September 24, 2009. The locations were set based on presence of physical microhabitat (i.e., undercut bank, overhead cover, bedrock outcrops, and pocket water) and observations of fish during the site visit and during snorkeling studies. Locations of the modeled transects are shown in Figure 4.2-1. Photos of IFIM transects at the calibration flows are included in Appendix 1. 4.2.3. Habitat Utilization The purpose of the habitat utilization component of the Instream Flow Study was to determine which meso- and microhabitat factors the fish in Grant Creek occupied to assess the impacts, if any, the Project would have on instream habitat. To maximize the knowledge of habitat selection factors for fish in Grant Creek, observations were made at the locations of the transects and fish habitat sites, as described in the previous section. Fish spawning and rearing microhabitat values were recorded at programmatically-selected sites in Reaches 1 through 4. Measured microhabitat use parameters varied by habitat units. During the Instream Flow TWG meeting on September 23, 2009, Table 4.2-2 was developed with input from TWG members. In 2013, measurements of 99 spawning pairs of Sockeye salmon were taken at flows ranging from 338 cfs – 469 cfs in the mainstem and 28 cfs – 74 cfs in the side channels. Measurements of 47 Coho salmon spawning pairs were taken at flows ranging from 169 cfs – 285 cfs; however, all but 4 of the observed Coho spawning occurred at flows ranging from 169 cfs – 179 cfs. For this reason, McMillen extended the probability of use curves to reflect the upper end of optimum utilization (i.e., value of 1.0) in the Cooper Creek curves. Only three Chinook salmon pairs were observed spawning; these were discarded and literature-based curves were used. Information relating to site-specific HSC was developed from these data and used in combination with HSC curves available in the existing literature and professional judgment to determine final HSC curves to be used in modeling. Development of final HSC curves was pursued as a collaborative effort with the Aquatics Resource Work Group (ARWG), which has been established to review aquatic data in 2014. HSC curves were combined with the transect measurements and mesohabitat characterizations to model changes in habitat as a function of discharge. Methods for normalizing values for HSC curves, using habitat utilization and habitat availability, are described in WDFW/WDOE (2013). HSC curves are found in Appendix 2. Habitat utilization data are covered extensively in Aquatic Resources Study – Grant Creek, Alaska Fisheries Assessment, Final Report (KHL 2014a).

Affected Species and Life Stages Fisheries resources of primary concern in Grant Creek are commercial and game fish that include Chinook (Oncorhynchus tshawytscha), Coho (O. kisutch), and Sockeye (O. nerka) salmon, Rainbow trout (O. mykiss), and Dolly Varden char (Salvelinus malma). All of these species have been documented to utilize portions of the study area during some part of their life cycles. Fish use Grant Creek in a variety of ways. Adults of the anadromous species use Grant Creek for upstream migration, spawning and rearing. Salmonid fry and juveniles use the creek for rearing and as a downstream migration corridor on their journey toward the sea. Proposed species and life stages for the Instream Flow Study are found in Table 4.2-4. 4.2.5. Field Methods Transects were oriented across the selected habitat unit to best capture the average condition of interest in that unit, such as spawning or rearing potential. Field data were collected at the Grant Creek transects at a high, several middle, and low flows for model calibration purposes. Generally, all field data were taken using the standard procedures described in Trihey and Wegner (1981) and Bovee (1982). Not all transects used the same benchmark. Head pin FINAL REPORT AQUATIC RESOURCES – HABITAT MAPPING / INSTREAM FLOW STUDY Grant Lake Hydroelectric Project Kenai Hydro, LLC FERC No. 13212 20 June 2014 elevations, hydraulic slopes, stage of zero flow (SZF), WSEs, and channel cross sections were measured using a Topcon auto level and stadia rod, using standard survey techniques. The surveyor tied these features to the transect benchmark to the nearest 0.01 feet. Table 4.2-4. Potential target species and life history stages to be modeled in the Grant Creek Instream Flow Study. Species Spawning Fry Rearing Juvenile Rearing Adult Rearing Sockeye Salmon Coho Salmon Chinook Salmon Rainbow Trout Dolly Varden Char A series of field measurements were taken in 2010. Due to the possibility of changes in bed profiles and hydraulic controls (i.e., SZF), all transects were resurveyed to determine if head or tail pins had moved or if high flow events since 2010 had altered the stream profile or the hydraulic controls. In addition, KHL collected discharge and stage data at a wide variety of flows in order to extend the extrapolation range of the models. Measurements in the main channel ranged from a low of 17 cfs, to a high of approximately 700 cfs. Depth and velocity distributions at the calibration flows were measured using a digital, Swoffer brand, propeller-type velocity meter mounted on a standard top-set wading rod. Velocity was measured at sixth tenths of the depth when depth was less than 2.5 feet and at two tenths and eight tenths of the depth where depths equaled or exceeded 2.5 feet, or when flow was influenced by an upstream obstruction. If prior investigations had adequate depth and velocity measurements and there were no bed elevation changes, KHL used those measurements. If the number of measurements was not adequate or if the bed profile had changed, KHL made additional measurements within the channel. Temporary staff gage levels and the time of day were recorded at the beginning and end of each transect measurement to note changes in stage; the outside staff height at the Grant Creek stream gage was also recorded. Substrate was classified using a three-digit code representing the most abundant particle size, the second-most abundant particle size, and the percentage of the most abundant particle size (see Table 4.2-3 for substrate classification). 4.2.6. Connectivity of Habitats Within Reach 5 During the 2013 field season, two transects (T510 and T520) that represented the areas sensitive to changes in flow and stage were selected and measured in the canyon (i.e., Reach 5). Cross sections were surveyed at both transects. Head and tail pins on each bank as well as a benchmark were surveyed to establish relative elevations. A tape was stretched horizontally across the channel and attached to the head and tail pins. With an auto level and stadia rod, elevations of the streambed and banks were surveyed at regular intervals along the tape and WSEs were surveyed at locations where accurate measurements could be obtained. Water surface elevations were surveyed at flows ranging from 17 cfs – 706 cfs. FINAL REPORT AQUATIC RESOURCES – HABITAT MAPPING / INSTREAM FLOW STUDY Grant Lake Hydroelectric Project Kenai Hydro, LLC FERC No. 13212 21 June 2014 Riverine Habitat Simulation (RHABSIM) uses a power function to calculate the stage-discharge relationship at transects. This stage/discharge relationship was used to calculate the water surface elevation for each simulated flow. Station location, streambed elevations, discharges, water surface stage, slope, and SZF were entered into the PHABSIM hydraulic model; depths at each station were simulated for the modeled range of flows. Depths equal to or exceeding the passage depth criteria for each species were tallied at each modeled flow. Adjoining cells with depths equal to or exceeding the criteria were also tallied. The total width of the cells in each of these categories at each modeled flow was divided by the total wetted width at each flow to compute the percent of the transect that is currently passable. Table 4.2-5 shows the species considered at each stream and the passage depth criteria used to evaluate fish passage success. Connectivity of the various pools and channels was measured and assessed using the Oregon Method (Thompson 1972). After 10 years of research on depth and velocity in streams in Oregon, Thompson concluded that the depth over “the shallow bars most critical of adult passage” was the feature that determined the likelihood of successful migration. Thompson recommends a minimum depth of 0.6 feet for large trout and 0.8 feet for Chinook salmon to achieve successful passage. The “Oregon Method”, as it is now commonly called, concludes that the passage flow is adequate when the depth criterion is met on at least 25 percent of the transect width and on at least a 10 percent continuous portion. Transect data were collected to determine where connectivity meets these criteria and where it does not. Connectivity was assessed concurrently with the Instream Flow Study conducted downstream in Reaches 1 – 4, at the same range of flows. Table 4.2-5. Species evaluated for connectivity in Grant Creek. Species Evaluated Minimum Depth Criteria Chinook Salmon 0.80 feet Coho and Sockeye Salmon 0.60 feet Dolly Varden Char and Rainbow Trout 0.40 feet 4.2.7. Data Analysis 4.2.7.1. Hydraulic Modeling Analysis and integration of physical stream measurements and habitat preference criteria require the use of a group of the RHABSIM (Riverine Habitat Simulation) computer programs. There are two main programs in the RHABSIM library: the hydraulic model (called HYDSIM), and the habitat model (called HABSIM). Hydraulic modeling involves two sequential steps. The first step is to develop a stage-discharge relationship, and the second step is velocity calibration. The stage is the height of the water surface elevation (WSE) at a location (in this case, at each transect). At a minimum of three widely separated calibration flows, stages and flows should be measured and recorded; generally, FINAL REPORT AQUATIC RESOURCES – HABITAT MAPPING / INSTREAM FLOW STUDY Grant Lake Hydroelectric Project Kenai Hydro, LLC FERC No. 13212 22 June 2014 the lower flow should be half or less of the next higher flow. A power function predicts the WSE and calculates the depth of the water at that flow by subtracting the bed profile from the WSE. At each point (station) along a transect, a velocity calibration is needed to estimate velocity. An average velocity for the river can be calculated at a transect if the flow and the cross sectional area of the river are known at the transect. Flow (Q, in cubic feet per second) = cross sectional area (A) X average velocity (V), and A=depth X width; thus V = Q/A. Velocity calibration allows fine-tuning of velocity distribution across a transect. Velocity is not uniform across a transect, but faster in some places and slower in others. Over a range of flows, it is possible to modify (either increase or decrease) the “cell” velocity relative to the average velocity by using a measured velocity to indicate relative resistance to flow or roughness. Successful velocity calibration generates reasonable approximations of the actual velocity measurements at the calibrated and extrapolated flows. Other velocity calibration methods are also available. The Habitat Simulation (HABSIM) program integrates the simulated hydraulic information from Hydraulic Calibration Simulation (HYDSIM) with HSC curves and quantifies habitat availability over a range of flows for the specified target species and life stages. Habitat quantification is expressed as an index called WUA, and is given in units of square feet of habitat per 1,000 linear feet of stream. 4.2.7.2. Hydraulic Modeling Procedures McMillen calibrated the Grant Creek hydraulic models using methods described below. All of the input decks were initially processed using the Problem Report subroutine of the Field Data Entry Module of RHABSIM. This program looks for errors in data placement and produces a hard copy of the pertinent information needed to run the model, including transect weighting factors, slopes, SZF, and WSE. 4.2.7.3. Hydraulic Model Calibration One of the goals of the hydraulic simulation is to have the model accurately simulate the measured velocities and depths at the calibration flows, while minimizing changes to the data. In this regard, only minor changes were made to the instream flow data in order for the model to more accurately predict cell velocities at the simulated flows. Only minor changes were made to the original input data. Most revisions fell into one of four categories: 1. Replacing a measured velocity of 0.0 feet/second with a velocity of 0.1 feet/second in some cells where there was depth but no measured velocity. The model “sees” a measured zero velocity as a blank and will attempt to fill that cell with a velocity based on a mass balance equation for the transect, taking into consideration slope, adjacent velocities, and the resistance of the bed of a channel to the flow of water in it (referred to as Manning’s N, a roughness coefficient). Replacing a measured velocity of 0.00 with a velocity of 0.01 or 0.1 often corrects this problem. 2. Changing the Manning’s N value to either reduce or increase the velocities in the given cell. Edge cells are often assigned high Manning's N values by the model. The FINAL REPORT AQUATIC RESOURCES – HABITAT MAPPING / INSTREAM FLOW STUDY Grant Lake Hydroelectric Project Kenai Hydro, LLC FERC No. 13212 23 June 2014 high N values slow the velocities through these cells, giving an unrealistic simulation of velocities. In these instances, the N values were manually reduced. 3. Adjusting the bed elevations at the stream margin cells slightly. 4. Changing the SZF in certain instances when it improved the mean error of the stage discharge relationship. Changes were kept to a minimum and the decks were revised only when specific changes improved model performance. The goal is to have the simulated velocities fall within 20 percent or 0.2 feet/second of the measured velocity, whichever is greater. Mean error (for both given and predicted discharges), ratio of measured versus predicted discharges, and B coefficients were all within the acceptable limits for PHABSIM calibration. Velocity Adjustment Factors (VAFs) are generally a measure of how well a model simulates the actual velocities. In a one-velocity set model, however, the VAFs are actually adjustment factors of discharge, not velocities, and a wider range of values is acceptable. A summary of VAFs and calibration details for all transects is presented in Appendix 3. Cross section, WSE, and flow hydraulic summaries are found in Appendix 4. All VAF values were within the acceptable range for one-velocity set models. A one-velocity set model tends to model velocities better in a downward, or decreasing direction; as the discharges are increased above the calibration flow measurement, drag on the banks (in the form of higher roughness coefficients) tends to underestimate habitat. Another calibration method, known as depth calibration, sets Manning’s N values to 0.06 and simulates velocities so that the thalweg and deeper areas are assigned higher velocities. This method tends to overestimate habitat slightly. To balance these differing WUAs, the results are averaged together for the higher flow ranges. 4.2.7.4. Transect Weighting In a typical PHABSIM study, transect weighting is dictated by the frequency of that particular mesohabitat type present in the study reach. Per previous consultation with the Instream Flow TWG, transects were placed on locations of known salmonid utilization (see Section 4.2), rather than representing gross habitat frequencies. Given this approach, all transects were weighted equally, so relative weighing and lengths were the same for all transects. 4.2.8. Measured Flows for Grant Creek When possible, McMillen collected up to five sets of stage/discharge data at each transect. This was in addition to two sets of stage/discharge measurements taken in 2010. In some instances, distributary or side channel transects were either dry or still frozen, precluding some measurements. Additional WSE measurements were taken in these two areas at a Grant Creek flow of approximately 440 cfs. Due to channel changes at Transect 330, a new calibration measurement was also taken at this flow. KHL collected WSEs at each transect at a very high flow (approximately 700 cfs, as measured by an Acoustic Doppler Current Profiler [ADCP]). These flows and a WSE at each transect were used to generate the stage-discharge relationships. The calibration flows are shown in Table 4.2-6 for each transect. Figures 4.2-1 and 4.2-2 show FINAL REPORT AQUATIC RESOURCES – HABITAT MAPPING / INSTREAM FLOW STUDY Grant Lake Hydroelectric Project Kenai Hydro, LLC FERC No. 13212 24 June 2014 the locations of these transects, as well as the main channel, side channels, and Reach 1 distributary.

Flow Partitioning in Grant Creek As shown in Figure 4.2-1, Grant Creek below the powerhouse consists of a main channel, several side channels, two low-velocity lobes (T200 and T300), a backwater channel (T210 and T230), a high flow overflow channel (when flows are approximately 450 cfs), and a distributary in Reach 1 that does not get wetted until approximately 190 cfs (T100 and T110). The Figure 4.2-2 map series also shows these features. The side channels in Reaches 2 and 3 are wetted at all flows; however, the smaller side channels may be frozen over in winter at low flows and temperatures. All of these channels affect flow at the Grant Creek measured transects. KHL ran regression analyses in order to partition the flow appropriately for the PHABSIM model. Table 4.2-7 summarizes the calculated partitioning of flow for each area of Grant Creek; Table 4.2-8 presents the table of flows used for the PHABSIM analysis.

FINAL REPORT AQUATIC RESOURCES – HABITAT MAPPING / INSTREAM FLOW STUDY Grant Lake Hydroelectric Project Kenai Hydro, LLC FERC No. 13212 33 June 2014 4.2.10. Production of WUA for Grant Creek After the hydraulic models were calibrated, transect weighting and relative lengths to simulate a 1,000-foot reach were added for the rearing and spawning life stages. Flow apportioned to each of the transects was added, and final hydraulic model runs were made to produce input for the HABTAT habitat model. Output from the hydraulic models was then used to determine changes in the Grant Creek water depths, velocities, surface area, and fish habitat throughout a range of flows from 10 cfs to 1,000 cfs, depending on individual study site. In order to develop the most accurate models, KHL conducted three model runs for each transect and performed the following analysis: A one-velocity set model was used to model down from the middle flow measurement (approximately 180 to 200 cfs in the main channel as measured at the gage). Both one-velocity set and depth calibration models were run from the middle flow measurement (approximately 180 to 200 cfs as measured in the main channel at the gage) up to 1,000 cfs. The WUA results from the one-velocity set and depth calibration models were averaged to produce one WUA table for each species and life stage at each transect (from 180 to 200 cfs upward to 1,000 cfs, as measured at the gage). The results of these model runs were then combined to produce WUA over the entire range of flows of interest. [Note: the exception to these measured flows was in the side channels in Reach 3. At Transect 330, a calibration measurement was taken at a flow of 440 cfs, as measured at the gage]. 5 RESULTS 5.1. Grant Creek Aquatic Habitat Mapping Grant Creek consists of six reaches; however, the focus of the mapping was on Reaches 1 – 5, located below the upstream migrational barrier. GIS maps of aquatic habitats in Grant Creek are found in Figures 5.1-1 and 4.2-2. There are two series of maps: the first series (Figure 5.1-1) shows mesohabitats found in Reaches 1 – 5 (pools, glides, etc.); the second series (Figure 4.2-2) shows aquatic habitats (undercut banks, overhead cover, etc.) in the same reaches. Table 5.1-1 summarizes mesohabitats found in Grant Creek. Riffle habitats were predominant, accounting for 50 percent of all habitats. This was consistent throughout all reaches, with the exception of the secondary channel in Reach 3. Riffle habitats were followed by pools (19.3 percent) and cascades (15.3 percent); all of the cascades were found in the canyon (Reach 5). FINAL REPORT AQUATIC RESOURCES – HABITAT MAPPING / INSTREAM FLOW STUDY Grant Lake Hydroelectric Project Kenai Hydro, LLC FERC No. 13212 34 June 2014 Table 5.1-2 shows habitat types (stream margin, overhead vegetation, undercut banks, and LWD) found in Grant Creek. LWD was sparse in the mainstem of Grant Creek. High flows in Grant Creek move LWD downstream and eventually into the Trail Lakes. In the side channels and distributaries, where flows and velocities are much less than in the main channel, LWD is relatively abundant.

Grant Creek Instream Flow Study 5.2.1. Weighted Usable Area Within the HABTAT program, output from the hydraulic modeling is combined with habitat suitability criteria for depth, velocity, and substrate/cover for the target species life stages. The output from this model is expressed as Flow (Q - cfs) versus WUA, which is an index of available habitat (in feet2 per 1,000 lineal feet of stream) for each species and life stage of concern. One-velocity set models and depth calibration models were developed to evaluate habitat at flows ranging from 10 – 1,000 cfs, as measured at the Grant Creek gage. Since one-velocity set models tend to predict velocities better when modeling lesser flows, a combination of one- velocity set and depth calibration models was used to evaluate flows > 200 cfs in the mainstem. Above the velocity calibration measurement, the WUA results of the two methods were averaged. The same methodology was used in side channels (Reaches 2/3), the distributary (T100 and T110), and in the mainstem where side channel habitat decreased flows in the mainstem (T320 and T330). Table 5.2-1 summarizes flows and models used to simulate flows in Grant Creek. Transects were run independently and were given the same weighting, since they were selected as being important rearing and spawning areas. WUA graphs and tables are found in Appendix 5 for the target species and life history stages for Grant Creek. Table 5.2-2 indicates which life history stages were modeled at each transect. Tables 5.2-3 to 5.2-23 and Figures 5.2-1 to 5.2-21 show Grant Creek Flow versus WUA graphs for the species and life history stages shown in Table 4.2-4. Appendix 5 includes the graphs and tables for the target species and life history stages for Grant Creek by transect. As stated in Section 4.9, the Reach 2 and 3 side channels are wetted at all flows, although low winter flows may result in freezing in the smaller side channels. The distributary in Reach 1 becomes wetted at a flow of approximately 190 cfs, while the overflow channel near the Reach 1/Reach 2 break becomes wetted at a flow of approximately 450 cfs.

Reach 5 Connectivity Appendix 6 includes bed profiles and water surface elevations for a range of flows for each transect modeled for the Instream Flow Study. This appendix also graphically represents the percent of the total wetted width that meets depth criterion, as well as meeting the 10 percent continuous criterion per flow for Chinook, coho and sockeye salmon, and Dolly Varden char and rainbow trout. Table 5.2-24 shows that for 25 percent of total width, the passage depth criterion for Chinook salmon, is met on individual transects from 7 cfs – 30 cfs, with an average of 30 cfs. Discharges for continuous passage meet criterion at flows ranging from 7 cfs – 25 cfs, with an average of 25 cfs. The discharges at which both passage criteria are met range from 7 cfs – 30 cfs, with an average of 30 cfs. The 25 percent of total width, the passage depth criterion for coho and sockeye salmon, is met on individual transects at flows ranging from 7 cfs – 15 cfs, with an average of 10 cfs. Discharges for continuous passage meet criterion at flows ranging from 7 cfs – 10 cfs, with an average of 10 cfs. The discharges at which both passage criteria are met range from 7 cfs – 15 cfs, with an average of 10 cfs. For Dolly Varden and rainbow trout, the passage depth criterion for 25 percent of total width is met on individual transects at 7 cfs. Discharges for continuous passage meet criterion also at a flow of 7 cfs. The discharge at which both passage criteria are met is at a flow of 7 cfs.

Grant Creek Aquatic Habitat Mapping Grant Creek is a higher gradient, very flashy stream. High flows and velocities limit the amount of LWD in the system because there are only a few places where LWD will collect in the main channel. Most wood is found in the distributary and the Reach 2/3 side channels, where flows are greatly reduced and are protected from the main discharges in Grant Creek. The system is dominated by riffles in the lower four reaches and cascades in Reach 5. Pools are also generally lacking in the mainstem. As with LWD, the exception is in the side channels and distributary. The other major habitat found with some abundance is undercut banks, primarily in Reaches 1 and 4. 6.2. Grant Creek Instream Flow Study 6.2.1. Grant Creek Habitat Preliminary results from the Instream Flow Study indicate that spawning is limited in Grant Creek due to lack of suitable spawning substrate; the substrate that is present is recruited from Reaches 5 and 6 (canyon). Substrates do not tend to be rounded, as observed in most high quality salmonid streams. The sediment from the canyon consists mostly of slate and greywacke (i.e., sandstone). When slate fractures, it tends to be platy (i.e., broad and flat), while greywacke fractures tend to be angular in nature (KHL 2014b). Spawning appears to be opportunistic and activity more directed by the presence of spawning sediment rather than by water depths and velocities. For example, KHL observed sockeye salmon spawning in 1 foot of depth and 1 foot per second velocities, while spawning activity was also observed about 30 feet away in the middle of the channel where depths of 3 to 4 feet and velocities up to 6 feet per second were noted. As indicated by the spawning WUA curves and field observations, much of the spawning occurs along the stream margins, where velocities and depths can be lower, and spawning substrates are perched. What was observed in the field, however, is that redds that were constructed along the stream margins at higher discharges were FINAL REPORT AQUATIC RESOURCES – HABITAT MAPPING / INSTREAM FLOW STUDY Grant Lake Hydroelectric Project Kenai Hydro, LLC FERC No. 13212 84 June 2014 left dry and exposed as Grant Creek flows diminished. This was particularly noted for sockeye spawning; fish were observed spawning at much higher flows than coho (flows were relatively stable during the 2013 coho spawning period). Significant side channel habitat exists in Grant Creek, notably in Reaches 2 and 3. Salmon were observed spawning in these side channels, which provide reduced flows and complex rearing habitats. There is also a hydraulic control at the upper entrance to the Reach 1 distributary, which prevents water from coursing through these habitats at flows below approximately 190 cfs. The control at the upper end of this distributary consists mainly of logs and larger-sized sediments, which have been deposited there by Grant Creek at higher flows as the stream cuts transversely to the opposite bank just downstream of the distributary. Many of these side channel habitats are either dry or frozen during the winter period due to the reduced flows. There is most likely a substantial, yet unquantified loss of production in these side channels due to desiccation and freezing. Habitat for salmonids could likely be increased by several methods, notably: 1) altering the upstream control in the Reach 1 distributary, adding additional flow at optimal spawning and rearing periods; and 2) increasing base flows, which would result in more water into the side channels in Reaches 2 and 3. 6.2.2. Connectivity Flows in Reaches 5 and 6 (i.e., the canyon) would be reduced by Project operations. There has been concern that these reduced flows would affect upstream connectivity of pool and other habitats within Reach 5. Two transects, which represented the more sensitive types of habitats within the canyon, were modeled using the Oregon Method (Thompson 1972). Analysis of these habitats, using the criteria recommended by Thompson (1972), indicates that connectivity is accomplished for trout at a flow of 7 cfs for both total wetted and continuous width. Connectivity for Sockeye and Coho salmon was accomplished at flows ranging from 7 cfs – 15 cfs, averaging 10 cfs for both transects. Chinook salmon passage is accomplished at flows ranging from 7 cfs – 30 cfs, averaging 25 cfs (continuous passage) and 30 cfs (total wetted width). Current utilization of the canyon by the target species has not been incorporated into this report. More information can be found in the Fisheries Assessment (KHL 2014a). 7 VARIANCES FROM FERC-APPROVED STUDY PLAN AND PROPOSED MODIFICATIONS 7.1. Grant Creek Aquatic Habitat Mapping There were no substantial variances from the FERC- and agency-approved study plan. Production of several analyses (e.g., incubation analysis, as mentioned in the Study Objectives), will be completed after consultation with the Aquatics Resource Work Group (ARWG) and integration with other disciplines. FINAL REPORT AQUATIC RESOURCES – HABITAT MAPPING / INSTREAM FLOW STUDY Grant Lake Hydroelectric Project Kenai Hydro, LLC FERC No. 13212 85 June 2014 7.2 Grant Creek Instream Flow Study There were no substantial variances from the FERC- and agency-approved study plan as related to the Instream Flow Study. KHL added a study component to examine connectivity in Reach 5 because salmonids had been observed in the canyon. Information related to wetted perimeter analysis with substrate and effective spawning, and lateral connectivity, is being developed cooperatively with the Instream Flow Sub-Committee of the ARWG.

Habitat Availability and Utilization Appendix 2b. HSC Curves FINAL REPORT AQUATIC RESOURCES – HABITAT MAPPING / INSTREAM FLOW STUDY Grant Lake Hydroelectric Project Kenai Hydro, LLC FERC No. 13212 Appendix 2 Page 1 June 2014 INTRODUCTION As part of the Grant Creek Instream Flow Study, Kenai Hydro, LLC (KHL) collected habitat utilization and habitat availability data for Chinook, sockeye, and coho salmon spawning in Grant Creek. These curves, once referred to as preference curves, are now called habitat suitability criteria (HSC) curves. HSC curve verification studies consist of three parts: 1. Determination of proportional habitat availability; 2. Determination of fish habitat utilization; and 3. Analysis of fish preference by determining ratio of habitat utilization to habitat availability. Curve development follows guidelines present in WDFW/WDOE (2013), which draws from Orth, Jones, and Maughan (1981), Bovee (1986), Slauson (1988), and Beecher et al. (1993). METHODS KHL consultants surveyed Grant Creek looking for Chinook, sockeye, and coho salmon spawning. Only measurements of fish observed actually spawning were taken. In the case of aggregate spawning (as is often observed with sockeye salmon), measurement of two of the fish in the aggregate were taken. Measurements of mean column velocity, depth, and substrate were taken on both sides of each redd measured. These were measurements of habitat utilization. Location of the redds (relative to transects), time, and flow in Grant Creek were noted. Once the locations of the fish were noted and measurements of utilization were taken, Grant Creek cross sections were taken downstream, upstream, and in the vicinity of the observed redds. If there were instream flow transects in the vicinity of the observed redds, the transect models were run at the flow at which spawning was observed. If there were no transects in the vicinity of the observed redds, measurements of depth and velocity were taken in Grant Creek below, across, and above the observed redds. RESULTS A total of 99 sockeye salmon, 47 coho salmon, and 3 Chinook salmon redds were measured. Due to long sample size, Chinook salmon data were not used; in this case and for rearing life history stages of all species in Grant Creek, literature curves based upon other sources (in Alaska, when available) were used. Table A.2-1 summarized flows, species, and locations of spawning sockeye and coho salmon.
