4 1.0 INTRODUCTION The El Dorado Irrigation District (EID or District) owns and operates the El Dorado Hydroelectric Project (Project No. 184), which is licensed by the Federal Energy Regulatory Commission (FERC). The Project No. 184 Monitoring Program requires monitoring of rainbow trout populations in six stream reaches associated with Project No. 184 facilities. The specific monitoring requirements for rainbow trout are defined in the Project 184 Rainbow Trout Monitoring Plan (Plan; EID 2010), which was approved by FERC on February 3, Rainbow Trout (Oncorhynchus mykiss) surveys were conducted between 1998 and 2001 (ECORP 2002) as part of the FERC relicensing effort. Results from these surveys were used to develop the ecological resource objectives as identified in Appendix B, Section 1 of the El Dorado Relicensing Settlement Agreement. Biomass indices (pounds/surface acre) were developed to serve as a baseline for ecological resource objective monitoring. Post-license monitoring for Rainbow Trout is required for two consecutive years at the beginning of each five-year period. The purpose of this monitoring is to evaluate the status of Rainbow Trout populations in comparison to the ecological resource objectives. The first of these paired monitoring efforts took place in 2011 and The results of the 2016 survey will be used in conjunction with the 2017 survey to compare the status of Rainbow Trout populations relative to the results as well as to the baseline biomass indices in order to evaluate whether resource objectives described in the Plan are being met. EID retained AECOM Technical Services, Inc. to conduct the 2016 monitoring surveys. This report presents the 2016 monitoring results; the 2016 surveys are the first year of monitoring in the second fiveyear period of post-license monitoring. 4

5 2.0 SURVEY LOCATIONS Rainbow population, density, and biomass surveys were conducted at six sampling sites: South Fork American River below Carpenter Creek (SO-2) Lower Echo Creek (EC-1) Lower Pyramid Creek (PY-1) Silver Fork American River at Forgotten Flat (SV-4) Lower Alder Creek (AR-1) Caples Creek below Kirkwood Creek (CA-3) Four sites (PY-1, CA-3, SV-4, and AR-1) are located on tributaries to the South Fork American River, one site (SO-2) is located on the South Fork American River, and one site (EC-1) is located on Echo Creek, a tributary to the Upper Truckee River. Site locations are provided in Figure 1. GPS coordinates for the upstream and downstream boundary of each sampling site is shown in Table 1. 5

8 El Dorado Irrigation District, FERC Project No. 184 Rainbow Trout Monitoring METHODS Methods were consistent with those used in prior sampling years. Sites sampled in 2011 and 2012 were located in 2016 using GPS coordinates and site photos. Sampling site boundaries were established in approximately the same location as previous years, except when habitat and flow conditions required slight adjustments. In these instances, historical boundaries were moved slightly to accommodate effective sampling. 3.1 Data Collection Sampling site boundaries were established at natural habitat breaks or other logical positions for block net placement. Block nets were installed to ensure a closed population by preventing fish from moving in or out of the sampling reach. At Lower Alder Creek (AR-1), an upstream block net was not needed because a natural instream cascade provided a sufficient barrier to fish movement. The upstream and downstream boundaries were documented at all sites by recording GPS coordinates and taking photographs. Prior to beginning the electrofishing fish sampling effort, water quality parameters (water temperature, dissolved oxygen, and conductivity) were measured and recorded using an YSI Pro 2030 meter. Based on water quality parameters, backpack electrofishing unit settings were adjusted to maximize capture efficiency and minimize potential injury to fish. When conductivity was lower than the desired range for effective electrofishing, salt (5 pound salt blocks) was added at the upstream end of a sampling reach and allowed to dissolve and disperse throughout the reach prior to beginning electrofishing. Conductivity was monitored continuously after adding salt; electrofishing began when water conductivity was within the desired range. Sampling via multi-pass (or depletion) electrofishing consisted of applying an electrical current to the water using between one and three backpack electrofishing units, depending on the width of the reach, to temporarily immobilize fish to allow capture. Field crews began electrofishing at the downstream end of the sampling site and worked in a methodical, upstream direction. A pass is defined as one complete electrofishing sampling effort from the downstream boundary to the upstream boundary. During each pass, captured fish were placed in 5 gallon buckets filled with oxygenated water, and transported to and placed in an instream holding livewell located downstream of the sampling reach. At the completion of each pass, captured fish were identified to species, weighed (g), measured (fork and total length, mm), and placed in a separate instream holding livewell. Three passes were typically made per sampling site. A fourth pass was conducted when three passes were insufficient to generate a viable depletion curve. When sampling was complete and all captures were processed, fish were released back into the sampling reach taking care to distribute throughout the reach and in appropriate habitat. Physical habitat data were measured and recorded at each sampling site at the conclusion of electrofishing efforts. The length of each sampling reach was divided into ten equally spaced transects. Width and depth was measured at each transect. Flow measurements were taken at a point within each site determined to have the most laminar flow. Measured water velocities were multiplied to calculate discharge in cubic feet per second (cfs). In some instances, suitable habitat for flow measurements was not found within the 8

9 El Dorado Irrigation District, FERC Project No. 184 Rainbow Trout Monitoring 2016 site boundaries. In these cases, flow measurements were taken in the closest location outside the site boundary where suitable conditions existed. 3.2 Data Analysis Fish capture data, taken from field data sheets (Attachment B), were entered into an Excel database. Rainbow Trout capture data were then converted to comma separated values (CSV) files and analyzed using MicroFish 3.0 software. Population and total weight estimates generated by MicroFish 3.0 were used to calculate density and biomass values presented in this report. 9

10 El Dorado Irrigation District, FERC Project No. 184 Rainbow Trout Monitoring RESULTS Results from the 2016 monitoring effort are presented in this report. Mean Rainbow Trout biomass and density estimates from the 2011 (Stillwater 2012) and the 2012 (ECORP 2013) monitoring efforts are presented in this report to show temporal change and evaluate how well targeted indices are being met in the context of the ecological resource objectives described in the Plan. Six fish species were observed among sampling sites and included Rainbow Trout, (Salmo trutta), (Salvelinus fontinalis), Sacramento (Catostomas occidentalis), California Roach (Hesperoleucus symmetricus), and Prickly Sculpin (Cottus asper). The majority of trout captured were Rainbow Trout, followed by Brown and Brook Trout. Results by sampling site are presented below. A summary of water quality parameters is shown in Table 2. Estimated Rainbow Trout densities and biomass are shown in Table 3 and in Figures 2 and 3. A summary of habitat parameters and habitat composition is shown in Table 4 and Table 5, respectively. 4.1 South Fork American River below Carpenter Creek (SO-2) The South Fork American River below Carpenter Creek was electrofished on September 7, The sampling site was moved roughly 20 meters downstream due to high flows through high gradient cascade habitat at the upstream end of the previously sampled reach. The site consisted of two river channels separated by a partially wetted gravel bar that extended the length of the reach. The two channels and gravel island were treated as one large braided channel for the electrofishing effort and the habitat assessment. Each electrofishing pass consisted of an upstream sampling effort through the entirety of the main channel (river left) followed by a similar effort on the side channel (river right). The sampling reach was feet (90.0 meters) in length with an average width of feet (37.7 meters; Table 4). Maximum depth was 2.7 feet and average depth was 0.8 feet. Predominant habitat types were pocket water (50%) and riffle (30%). Predominant substrate types were cobble (50%) and boulder (44%). Onsite discharge during sampling was 72.9 cfs compared to 70.6 cfs in 2011 and 20.0 cfs in Discharge recorded at the stream gauge located on South Fork of the American River below Kyburz (EID gage A-12; USGS ID ) at the time of sampling was 56.8 cfs. A total of 107 Rainbow Trout (152 in 2011 and 94 in 2012), 13 Sacramento Sucker, and 38 California Roach were captured. The total weight of Rainbow Trout was 2,769.4 g compared to 4,782 g in 2011 and 2,721.4 g in Rainbow Trout density was estimated at 2,557 fish/mile compared to 3,703 fish/mile in 2011 and 1,991 fish/mile in Rainbow Trout biomass was estimated at 9.7 lbs/acre compared to 20.6 lbs/acre in 2011 and 12.0 lbs/acre in Lower Echo Creek (EC-1) Lower Echo Creek was electrofished on September 8, Fish capture efficiency was less than optimal due to the high amount of large wood debris and logjams in the sampling reach (see photos, Attachment A). Fish were often immobilized by the electrical current but trapped within woody debris piles. For this reason, the Rainbow Trout depletion pattern after three passes was insufficient to generate a viable depletion curve, and thus, a fourth pass was conducted. 10

11 El Dorado Irrigation District, FERC Project No. 184 Rainbow Trout Monitoring 2016 The sampling reach was feet (95.0 meters) in length with an average width of 14.8 feet (4.5 meters; Table 4). Maximum depth was 1.3 feet and average depth was 0.3 feet. Predominant habitat types were run (60%) and backwater pool (25%). Predominant substrate types were cobble (50%) and gravel (28%). Flow within and near the sample reach was insufficient to register on field equipment. Discharge recorded at the stream gauge located at the outlet of Echo Lake (EID gage A-43) at the time of sampling was 0.2 cfs compared to 3.4 cfs in 2011 and 2.1 cfs in A total of 13 Rainbow Trout (5 in 2011 and 2 in 2012), 64 Brown Trout, and 93 Prickly Sculpin were captured. The total weight of Rainbow Trout was 136 g compared to g in 2011 and 78.3 g in Rainbow Trout density was estimated at 339 fish/mile compared to 143 fish/mile in 2011 and 72 fish/mile in Rainbow Trout biomass was estimated at 4.3 lbs/acre compared to 3.5 lbs/acre in 2011 and 2.4 lbs/acre in Lower Pyramid Creek (PY-1) Lower Pyramid Creek was electrofished on September 9, Similar to previous years, conductivity was too low to effectively capture fish via electrofishing. Therefore, salt was added prior to each pass and conductivity was closely monitored throughout the day (Table 2). The sampling reach was feet (92.6 meters) in length with an average width of 23.3 feet (7.1 meters; Table 4). Maximum depth was 1.4 feet and average depth was 0.7 feet. Predominant habitat types were run (50%) and riffle (25%). Predominant substrate types were cobble (45%) and bedrock (30%). Onsite flow measurements were not recorded. Discharge recorded at the stream gauge located on Pyramid Creek below US Highway 50 (EID gage A-40; USGS ID ) at the time of sampling was 3.4 cfs compared to 26.3 cfs in 2011 and 2.1 cfs in A total of 88 Rainbow Trout (40 in 2011 and 62 in 2012) and 5 Brown Trout were captured. The total weight of Rainbow Trout was 1,697.5 g compared to 1,017.7 in 2011 and g in Rainbow Trout density was estimated at 1,980 fish/mile compared to 2,509 fish/mile in 2011 and 1,073 fish/mile in Rainbow Trout biomass was estimated at 29.9 lbs/acre compared to 38.8 lbs/acre in 2011 and 8.7 lbs/acre in Silver Fork American River at Forgotten Flat (SV-4) Silver Fork American River at Forgotten Flat was electrofished on September 12, The sampling reach was feet (98.0 meters) in length with an average width of 36.1 feet (11.0 meters; Table 4) Maximum depth was 2.7 feet and average depth was 1.1 feet. Predominant habitat types were riffle (55%) and pocket water (30%). Predominant substrate types were cobble (35%) and bedrock (25%). Onsite discharge during sampling was 15.4 cfs compared to 12.7 cfs in 2011 (2012 discharge unavailable). Discharge recorded by EID at Silver Fork below Oyster Creek Confluence (EID gage A-9 + A-24) at the time of the 2016 sampling was 12.8 cfs. A total of 156 Rainbow Trout (83 in 2011 and 57 in 2012) and 29 Brown Trout were captured. The total weight of Rainbow Trout was 3,323.3 g compared to 2,338.2 g in 2011 and 1,112.9 in Rainbow Trout density was estimated at 3,760 fish/mile compared to 1,744 fish/mile in 2011 and 985 fish/mile in Rainbow Trout biomass was estimated at 40.1 lbs/acre compared to 27.4 lbs/acre in 2011 and 8.4 lbs/acre in

12 El Dorado Irrigation District, FERC Project No. 184 Rainbow Trout Monitoring Lower Alder Creek (AR-1) Lower Alder Creek was electrofished on September 13, A large pool (depths > 5 feet) located at the upstream end of the sampling reach was mostly inaccessible to electrofishing. Numerous fish, including trout, were observed but not captured in this pool. The sampling reach was feet (99.0 meters) in length with an average width of 13.5 feet (4.1 meters; Table 4). Maximum depth was 3.4 feet and average depth was 0.9 feet. Predominant habitat types were riffle (55%) and pool (15%). Predominant substrate types were cobble (40%) and boulder (25%). Onsite discharge during sampling was 0.5 cfs compared to 4.6 cfs in 2011 and 0.2 cfs in Discharge recorded by EID at Alder Creek below diversion (EID Station ID A-13) at the time of sampling was 0.4 cfs. A total of 124 Rainbow Trout (165 in 2011 and 67 in 2012), 46 Sacramento Suckers, and 64 California Roach were captured. The total weight of Rainbow Trout was g compared to 2,710.3 g in g in Rainbow Trout density was estimated at 2,339 fish/mile compared to 3,251 fish/mile in 2011 and 1,288 fish/mile in Rainbow Trout biomass was estimated at 15.3 lbs/acre compared to 42.2 lbs/acre in lbs/acre in Caples Creek below Kirkwood Creek (CA-3) Caples Creek was electrofished on September 14, Much of the habitat encountered in this reach was difficult or impossible to effectively sample because many of the banks were undercut as much as 5 feet and water depths in some places were greater than 4 feet. The sampling reach was feet (99.0 meters) in length with an average width of 26.2 feet (8.0 meters; Table 4). Maximum depth was 4.4 feet and average depth was 1.1 feet. Predominant habitat types were run (30%) and lateral scour pool (30%). Predominant substrate types were gravel (45%) and sand (35%). Onsite discharge during sampling was 43.2 cfs compared to 26.8 cfs in cfs in Discharge recorded by EID at Caples Creek at Caples Lake outlet (EID gage A-6; USGS ID ) at the time of sampling was 30.4 cfs. A total of 48 Brook Trout and 2 Brown Trout were captured. No Rainbow Trout were captured at this site in 2016; therefore, density and biomass indices were not calculated. No Rainbow Trout were captured in 2011 and 4 were captured in

17 El Dorado Irrigation District, FERC Project No. 184 Rainbow Trout Monitoring CONCLUSIONS The next rainbow trout fish population monitoring effort is scheduled for 2017; the mean biomass for 2016 and 2017 monitoring efforts will be used to evaluate if targeted rainbow trout biomass values are being met for the project reaches. Because the rainbow trout biomass estimates in this report are for 2016 only, any conclusion as to whether the ecological resource objectives are being achieved would be premature. However, the 2016 rainbow trout biomass estimates and associated biomass indices are summarized here as a general reference. The biomass estimates (lbs/acre) from the 2016 sampling efforts are higher than biomass indices at two sites: Lower Pyramid Creek (PY-1) and Silver Fork American River at Forgotten Flat (SV- 4). The biomass estimates (lbs/acre) from the 2016 sampling efforts are lower than biomass indices at four sites: South Fork American River below Carpenter Creek (SO-2), Lower Echo Creek (EC-1), Lower Alder Creek (AR-1), and Caples Creek below Kirkwood Creek (CA-3). The 2016 biomass estimates are higher than the mean biomass estimate from the sampling efforts at three sites: Lower Pyramid Creek (PY-1), Silver Fork American River at Forgotten Flat (SV-4), and Lower Echo Creek (EC-1). For two sites, South Fork American River below Carpenter Creek (SO-2) and Lower Alder Creek (AR-1), the 2016 biomass estimates are more than 20% less than the mean biomass estimate from sampling efforts. The 2016 biomass estimate for Caples Creek below Kirkwood Creek (CA-3) is zero because Rainbow Trout were not captured in this reach during the 2016 sampling efforts. 17
