June 6, 2014 Grant Lake Hydroelectric Project To: Mike Salzetti, HEA Project: Grant Lake Hydroelectric Project From: Morton D. McMillen, P.E. Andre Ball, P.E. (WA) Cc: Cory Warnock File Date: June 6, 2014 Job No: 13-102 Subject: Grant Creek Hydraulic Analysis 1.0 INTRODUCTION McMillen, LLC (McMillen) has been retained by Homer Electric Association, Inc. (HEA) to provide engineering support for the proposed Grant Lake Hydroelectric Project (Project) FERC application. The project would be located near the community of Moose Pass, Alaska, approximately 25 miles north of Seward, Alaska. 1.1 Purpose and Scope The purpose of this Technical Memorandum (TM) is to present the analyses and results of a hydraulic analysis of Grant Creek. The analysis presented within this TM utilized the available data from previous studies, ongoing studies being conducted by McMillen, and the results of TM 001, Grant Creek Hydrologic Analysis. The primary objectives of this TM are: • Utilize the cross-sections surveyed for the IFIM study to develop a HEC-RAS model of the Grant Creek channel from near the powerhouse location to near the gage location. • Determine the water surface profiles along Grant Creek for various flows and develop a tailwater rating curve for the powerhouse tailrace channel and Grant Creek confluence. • Determine the 100-year flood event water surface elevation at the proposed powerhouse location. 1.2 Project Description As outlined in the application for a preliminary permit (HEA, 2011) the proposed Project consists of constructing a new 5-Megawatt (approximate) hydroelectric facility on Grant Lake and Grant Creek near Moose Pass, Alaska. The new Project would divert water from Grant Lake and deliver the flow to a powerhouse located near the outlet of the existing Grant Creek natural, incised rock canyon. The Project would include the following major components: • Diversion structure at the natural outlet of Grant Lake. (under consideration) • An intake structure in Grant Lake. • A tunnel extending from the lake intake to just east of the powerhouse. McMillen, LLC Page 2 Homer Electric Association, Inc. June 6, 2014 Grant Creek Hydroelectric Project • A powerhouse with two Francis turbines providing an anticipated combined 5-Megawatt output. The maximum design flow will be approximately 385 cfs. • Tailrace detention pond. • Switchyard with disconnect switch and step-up transformer. • An overhead or underground transmission line. • A pole mounted disconnect switch where the transmission line intersects the main power distribution line. 1.3 Project Background Grant Lake has been studied on multiple occasions since the 1950’s as a potential hydropower site. The previous work efforts included: • 1954 – R.W. Beck and Associates preliminary investigation • 1955 – U.S. Geological Survey (USGS) geological investigations of proposed power sites at Cooper, Grant, Ptarmigan, and Crescent Lake • 1980 – CH2M Hill prefeasibility study • 1981 – U.S. Army Corps of Engineers (USACE) National Hydroelectric Power Resources Study • 1984 – Ebasco Services Project Feasibility Analysis (Ebasco, 1984) • 2010 – HDR Grant Lake/Falls Creek Hydroelectric Project – Environmental Baseline Studies (HDR, 2010) On August 6, 2009, Kenai Hydro LLC filed a Pre-Application Document (PAD), along with a Notice of Intent to file an application for an original license for the Grant Lake/Falls Creek project. FERC subsequently approved the use of the Traditional License Process for development of the license application and supporting documents. In 2009-2010, HDR completed a series of environmental baseline studies which were summarized in their report dated January 2010. A second preliminary permit was issued by FERC in 2012. As part of these previous studies, the hydrologic conditions within the Grant Creek basin were evaluated and flows available to support a hydroelectric facility were evaluated. The most expansive analysis was completed as part of the Ebasco feasibility study. These previous studies and available gage data were used as the basis for the current hydrologic analysis. The subsequent gage data collected in 2009 (HDR, 2010) and 2013 by McMillen, along with the original USGS stream gage data (USGS Station 15246000) served as the basis for the flow estimation. 1.4 Grant Creek Description Grant Creek is the only natural outlet from Grant Lake and is located at the south end of the lake (Figure 1). Grant Creek is approximately 1 mile long and flows west from Grant Lake and discharges into the narrows that connect the Upper Trail Lake to Lower Trail Lake. The average gradient of Grant Creek is 207 feet per mile. The U.S. Geological Survey (USGS) had previously operated a stream flow gage (Station 15246000) on Grant Creek, but this gage is no longer McMillen, LLC Page 3 Homer Electric Association, Inc. June 6, 2014 Grant Creek Hydroelectric Project operated. Intermittent stream gaging has been conducted on Grant Creek by Ebasco in the early 1980’s and HDR in 2009 (Ebasco, 1984) (HDR, 2010). In 2013, McMillen reestablished streamflow measurements at the historic USGS gage location (GC200). McMillen evaluated streamflow statistics for Grant Creek as documented in TM 001 (McMillen, 2014). The mean annual discharge in Grant Creek is 193 cubic feet per second (cfs) and the average channel width is 25 feet. The upper portion of Grant Creek flows through a steep walled, canyon section with multiple waterfalls, abundant bedrock, and large boulders in the channel. The lower portion of the creek is less turbulent, less channelized, and has more gravel shoals (Ebasco 1984). The channel bifurcates near the mouth and has a network of distributaries. Figure 1. Grant Lake Hydroelectric Project Location Map 2.0 HYDRAULIC DATA SUMMARY The data sources used to conduct the hydraulic analysis included field surveys and observations, as well as previous reports. During the 2013 fieldwork season, McMillen personnel collected channel cross section information and measured water levels as part of the Water Resources and Instream Flow Incremental Methodology (IFIM) studies. Additional background information about Grant Creek was available in the previous studies completed by Ebasco and HDR. The flood hydrology used for the hydraulic simulation is documented in a separate McMillen technical memorandum, TM 001 Grant Creek Hydrologic Analysis (McMillen, 2014). Table 1. summarizes the peak streamflow statistics for Grant Creek.

The HEC-RAS program contains one-dimensional river analysis components for steady flow water surface computations, unsteady flow simulation, movable boundary sediment transport computations, and water quality analysis. The model utilizes common geometric data representation and geometric and hydraulic computation routines. A description of the model development, calibration, and results for Grant Creek are presented in the following paragraphs. 3.1 Model Geometry The model geometry for the Grant Creek HEC-RAS model was based on the surveyed channel cross sections collected in spring 2013 for an Instream Flow Incremental Methodology (IFIM) study (documented in the Aquatic Resource Study report). An additional survey was performed in fall 2013 to establish a common vertical datum and define the channel slope. In total, eight surveyed cross sections were used, representing a 2,060 foot long portion of Grant Creek. Table 2 summarizes the cross sections and their associated downstream reach lengths. Figure 2. (attached), shows the IFIM study section locations and can be cross referenced to the cross sections used in the HEC-RAS model by utilizing Table 2. Interpolated cross sections were added to the HEC-RAS model to reduce the distance between cross-sections, which provides a more stable hydraulic model. After interpolating cross-sections, the maximum modeled distance between cross sections was no more than 50 feet. A schematic of the HEC-RAS model geometry for Grant Creek is shown in Appendix A. Table 2.

June 6, 2014 Grant Creek Hydroelectric Project For this analysis, the hydraulic model was set up to represent Grant Creek as a single channel. In one location, there is a side channel that flows to the left of the main channel. The side channel begins downstream of T400 and rejoins the main channel between T300 and T230. At the time of this analysis, the hydraulic information available for the side channel was limited, and thus, the side channel was omitted from this initial hydraulic model. Based on a review of the overall creek hydraulics and controls, the side channel was considered to have minimal impact on the hydraulic gradeline at the area of interest near the proposed powerhouse tailrace location. 3.2 Model Calibration Observed water surface elevations at the surveyed cross sections were used to calibrate the HEC- RAS model. Five different discharges were simulated, ranging from 17 cfs to 706 cfs. Due to the steep grade of the creek, the model was run in the mixed flow regime with critical depth boundary conditions at the upstream and downstream ends. The mixed flow regime allows the model to determine if the section is supercritical or subcritical. The model computed a subcritical flow regime for most of the reach. The Froude numbers ranged between 0.4 and 0.7 for the upper half of the model. The model was calibrated by modifying the channel roughness, Manning’s ‘n’, as this was the most uncertain variable that could be adjusted. Any roughness adjustments were done within the range of roughness that is acceptable for the channel conditions (Barnes, 1967 and Brunner, 2010). In addition to modifying the roughness, ineffective flow areas were added to some cross sections, outside of the main channel, to refine the model. The calibration and refinement efforts focused on calibrating the model to best represent the creek in the reach between T410 and T430 since this is where the powerhouse tailrace will join the main channel. The resulting n-values used in the calibrated version of the Grant Creek are shown in Table 3. Table 3. Grant Creek Modeled Roughness Values Cross Section Name (IFIM Study) HEC-RAS Station (ft) Main Channel Roughness (n) Overbank Roughness (n) T220 50 0.07 0.10 T230 82 0.07 0.10 T300 932 0.07 0.10 T310 1061 0.07 0.10 T400 1381 0.07 0.08 T410 1435 0.09 0.15 T430 1865 0.07 0.15 T510 2110 0.07 0.15 The Ebasco report mentions a HEC-2 (HEC-RAS predecessor) model of Grant Lake outlet channel. The roughness values used in that model were n = 0.06 for the main channel and n = 0.10 for the overbank areas. It is unclear if these roughness values were computed based on field data or if they were selected based on reference literature. The new HEC-RAS model described in this memorandum required roughness values (Table 3) that were at the upper end of McMillen, LLC Page 6 Homer Electric Association, Inc. June 6, 2014 Grant Creek Hydroelectric Project acceptable values to bring the modeled water surface elevations closer to the observed water surface elevations. Manning’s n-values are known to be higher for mountain streams such as Grant Creek (Barnes, 1967). Furthermore, these calibration measurements were taken at lower flows and it is also known that Manning’s n-values for boulder mountain streams are higher for low flows because the roughness creates greater drag relative to streamflow when streamflow depths are lower (Bathurst, 1985 and Whol, 2000). The highest discharge available for the calibration was 706 cfs, whereas the lowest modeled flood flow, the 2-year event, was 961 cfs. The observed and modeled water surface elevations for cross sections T410 and T430 are shown in Figure 3 and Figure 4 respectively. All modeled water surface elevations are within 0.2 feet of the observed water surface elevations. McMillen, LLC Page 7 Homer Electric Association, Inc.

June 6, 2014 Grant Creek Hydroelectric Project 3.3 Channel Roughness Sensitivity Analysis As discussed in the Model Calibration section, the roughness values required to calibrate to the known water surface elevations were relatively high. A sensitivity analysis was conducted to evaluate how much influence the channel roughness had on the modeled water surface elevation. A revised model geometry was created that had lower roughness values that coincided more with the roughness values documented for boulder filled mountain streams (Barnes, 1967). For the sensitivity run, all cross sections were assigned roughness values of n = 0.055 for the main channel and n = 0.080 for the overbanks. The sensitivity n-values are lower than the calibrated n- values which will result in lower water surface elevations and higher flow velocities for a given discharge. Table 4 compares the water surface elevations resulting from the ‘calibrated’ n-values and the ‘sensitivity’ n-values for cross sections T410 and T430. At lower flows, in the flow range used for calibration, the water surface elevations only vary by a few tenths of a foot. At the 100- year flood discharge, the calibrated n-values result in water surface elevations that are 0.9 and 0.6 feet higher, relative to the sensitivity n-value water surface elevations, for cross sections T410 and T430 respectively. The calibrated n-values are conservative since it is likely that the effective n-values will be lower at flood flow conditions, thus there is confidence that an observed 100-year flood elevation will not exceed the modeled 100-year flood elevation.

June 6, 2014 Grant Creek Hydroelectric Project 4.0 CONCLUSIONS AND RECOMMENDATIONS 4.1 Conclusions This technical memorandum describes the hydraulic model for Grant Creek that will be used for the powerhouse tailrace design. The cross sections and water surface calibration information used in the model were obtained from the 2013 IFIM study. Additional cross-sections were interpolated in the HEC-RAS model to provide shorter distances between modeled cross sections. During the model calibration, the model roughness was adjusted to a relatively high level, while still being considered reasonable, in order to match the observed water surface elevations. Based on the modeling conducted for this task, the 100-year discharge (3,310 cfs) for Grant Creek is expected to have a water surface elevation of approximately 521.8 feet (depth of 6.4 feet) at the downstream end of the powerhouse tailrace. The water surface elevation associated with the 100-year discharge is located at the top of the extents of the surveyed cross section. 4.2 Recommendations The hydraulic analysis presented within this TM estimated a water surface elevation of 521.8 feet at the downstream end of the proposed tailrace for the 100-year flood event of 3,310 cfs. This elevation represents a conservative estimate due to the higher n-values used for the model calibration. This elevation, along with the estimated tailwater rating curve, is recommended for use in developing the site grading plan and corresponding flood protection elevations.
