Juvenile Salmonid Collection System (JSCS) Pilot Project Fish and Environmental Data – McCloud River  and Shasta Reservoir (2022–2025)

The California Department of Water Resources (DWR) conducted the Juvenile Salmonid Collection System (JSCS) Pilot Project from 2022 — 2025 to test new methods in fish capture and collect juvenile winter-run Chinook Salmon in the McCloud River (Wintu name: Winnemem Waywaket) as part of the greater effort to assess the feasibility of Chinook Salmon reintroduction above Shasta Dam. The goal of the JSCS Pilot Project was to test the performance of the JSCS structure in the McCloud Arm of Shasta Reservoir and to design, fabricate, and test configurations of the JSCS fish trap. DWR tested initial structural components of the JSCS in Shasta Reservoir in 2022 and operated the complete system at five sites across the reservoir–riverine interface in the McCloud Arm of Shasta Reservoir 2023 — 2024. Based on the results for those years, DWR redesigned the trap (JSCS V2) and deployed it in riverine conditions downstream of the McCloud Bridge Campground between September 30 — December 1, 2025. This dataset summarizes the data collected for the pilot study including environmental data collected on and around the JSCS fish trap, structural performance data for the JSCS fish trap, and fish capture data from the JSCS fish trap.

2023 Enhanced Predatory Fish Removal and Relocation Study

The Enhanced Predatory Fish Removal and Relocation Study (EPFRRS) was implemented from March 2021 through June 2023. The EPFRRS was included in the proposed action for the 2019 state and federal endangered species consultation for the long-term operations of the Central Valley Project and State Water Project. The goal of the EPFRRS was to use the most successful methods from previous predator relocation studies conducted by the Department of Water Resources (DWR) from 2016 to 2020, including the Predator Reduction Electrofishing Study (PRES) and the Predatory Fish Relocation Study (PFRS), to reduce predation mortality on protected fish species in Clifton Court Forebay (CCF), primarily juvenile Chinook Salmon and steelhead.

In 2023, predator collection and relocation were conducted from January 3 through June 1. Cancellations occurred during inclement weather conditions that made sampling unsafe (e.g., high winds or rain). There were three gear types used during the 2023 effort: electrofishing, beach seining, and hoop trapping. Electrofishing consisted of two to three electrofishing boats focusing on hotspots identified during the PRES and during the 2021 and 2022 EPFRRS efforts. Hoop traps were deployed for 24-48 hours of passive fishing, when possible, given SWP operations. When hoop traps could not be fished and an additional electrofishing boat was available, the third electrofishing boat was fished instead. Predatory fish removed included black basses, Striped Bass, catfish, and sunfish. However, sunfish were removed opportunistically and were not specifically fished for. Fieldwork was scheduled for four days a week each week. In total, predator relocation was conducted on 48 days during the 2023 field season, which is more than the 2021 field season (26.5 days) which was impacted by the COVID-19 pandemic. However, despite the field season being shorter by nearly a month, the 2022 field season had more days the field (55 days), primarily due to weather conditions.

2022 Enhanced Predatory Fish Removal and Relocation Study

The Enhanced Predatory Fish Removal and Relocation Study (EPFRRS) was developed as part of the proposed action during the 2019 Reinitiation of Consultation on Long-Term Operation of the Central Valley Project and State Water Project with the National Marine Fisheries Service (NMFS) (ROC on LTO) and was included in the Incidental Take Permit for the State Water Project (SWP ITP). The goal of EPFRRS is to use the most successful methods from previous studies, such as the Predator Reduction Electrofishing Study (PRES) and the Predatory Fish Relocation Study (PFRS), to reduce predation on protected fish species in Clifton Court Forebay (CCF), primarily juvenile Chinook Salmon and steelhead.

The EPFRRS 2022 field season ran from January 3 through May 12, with a one week cancellation from January 10 through January 14. Cancellation was for two reasons. 1) There were staff that contracted COVID, so fieldwork was cancelled to avoid potential exposures, and 2) there was a temporary increase in the presence of Sacramento Splittail in CCF.

The 2021 field season of EPFRRS ran from March 8 through May 12, following a two-month delay due to the COVID-19 pandemic. Additionally, there was a 2-week pause during the field season, beginning on April 14 and running through April 27, due to COVID-19 concerns. There were four gear types used during the 2021 field season; electrofishing, beach seine, hoop traps, and hook-and-line.

2020 Clifton Court Forebay Predatory Fish Relocation Study

The Clifton Court Forebay (CCF) Predatory Fish Relocation Study (PFRS) was implemented in response to the National Marine Fisheries Service (NMFS) letter dated April 9, 2015. The letter required the California Department of Water Resources (DWR) immediately implement interim measure (a) of condition 3 as part of the larger effort to comply with Reasonable and Prudent Alternative (RPA) Action IV.4.2(2) of the 2009 Biological Opinion and Conference Opinion on the Long-term Operations of the Central Valley Project and State Water Project (NMFS BiOp; NMFS 2009). The PFRS involved capturing and relocating predatory fish from CCF to Bethany Reservoir with the goal of reducing pre-screen loss of protected fish species, particularly Chinook Salmon and steelhead.

The PFRS was two years in duration. The Water Year 2019 field season (2019 field season) tested the effectiveness of 5 commercial-type fishing gears and acquired data and other information to advise any gear modifications and method refinements to improve catch effectiveness. The Water Year 2020 field season (2020 field season) incorporated knowledge gained from the 2019 field season to modify and refine the gears and their methodologies to maximize predatory fish capture.

2019 Clifton Court Forebay Predatory Fish Relocation Study

The Clifton Court Forebay (CCF) Predatory Fish Relocation Study (PFRS) was implemented in response to the National Marine Fisheries Service (NMFS) letter dated April 9, 2015. The letter required the California Department of Water Resources (DWR) to immediately implement interim measure (a) of condition 3 as part of the larger effort to comply with Reasonable and Prudent Alternative (RPA) Action IV.4.2(2) of the 2009 Biological Opinion and Conference Opinion on the Long-term Operations of the Central Valley Project and State Water Project (NMFS BiOp; NMFS 2009). The PFRS was two years in duration. The 2019 field season was an initial attempt to test the effectiveness of five commercial-type fishing gears and to acquire the necessary information to advise any gear modifications and method refinements to improve catch effectiveness. The PFRS involved capturing and relocating predators from CCF to Bethany Reservoir with the goal of decreasing pre-screen loss of protected fish species with an emphasis on Chinook Salmon and steelhead.

Predatory fish included black basses, catfish, and Striped Bass. Three “active” gears (beach seines, lampara nets, Kodiak trawls) were deployed, pulled through the water, and retrieved by field staff. Two “passive” gears (hoop traps and fyke traps) were placed in the water for ~24 h for each sample to collect predatory fish and then retrieved by field staff. Field work typically occurred 4 days per week between 3/1/2019 and 6/4/2019 with 3-4 gears conducted each day.

2018 Clifton Court Forebay Predator Reduction Electrofishing Study

The Clifton Court Forebay (CCF) Predator Reduction Electrofishing Study (PRES) was implemented in response to the National Marine Fisheries Service (NMFS) letter dated April 9, 2015, requiring that the California Department of Water Resources (DWR) immediately implement interim measure (a) of condition 3 as part of the larger effort to comply with Reasonable and Prudent Alternative (RPA) Action IV.4.2(2) of the 2009 Biological Opinion and Conference Opinion on the Long-term Operations of the Central Valley Project and State Water Project. The PRES length was three years, beginning with a pilot year effort in 2016, a 2017 effort to refine methods and determine the main factors affecting predator catch, and the 2018 effort focused on maximizing predator removal based on knowledge gained during the 2016 and 2017 campaigns. The PRES involved electroshocking and removing predators from CCF and transporting them to Bethany Reservoir with the goal of decreasing pre-screen loss of protected fish species with an emphasis on Chinook Salmon and steelhead.

During the 2018 field effort we focused on maximizing removal of predatory fish based on lessons learned and recommendations from the 2016 and 2017 efforts. Effort increased by fishing 4 days per week using 3 concurrent electrofishing boats (2017 field work used 2 boats on 3 days per week). Fishing removals focused primarily on the locations with highest catch rates identified in 2017: the Intake Canal, Scour Hole, and shore lines. In addition, sunfish species were added to the list of predatory fish removed.

2017 Clifton Court Forebay Predator Reduction Electrofishing Study

The Clifton Court Forebay (CCF) Predator Reduction Electrofishing Study (PRES) was implemented in response to the National Marine Fisheries Service (NMFS) letter dated April 9, 2015, requiring that the California Department of Water Resources (DWR) immediately implement interim measure (a) of condition 3 as part of the larger effort to comply with Reasonable and Prudent Alternative (RPA) Action IV.4.2(2) of the 2009 Biological Opinion and Conference Opinion on the Long-term Operations of the Central Valley Project and State Water Project. The PRES length was three years, beginning with a pilot year effort in 2016, a 2017 effort to refine methods and determine the main factors affecting predator catch, particularly spatial patterns, and a 2018 effort focused on maximizing predator removal based on knowledge gained during the 2016 and 2017 campaigns. The PRES involved electroshocking and removing predators from CCF and transporting them to Bethany Reservoir with the goal of decreasing pre-screen loss of protected fish species with an emphasis on Chinook Salmon and steelhead.

During the 2017 field effort we focused on refining methods based on lessons learned and recommendations from the 2016 effort, determining spatial and temporal patterns in predator catch rates using a standardized electrofishing sampling regime, and assessing environmental variables that may affect catch rates. In addition, we assessed factors contributing to mortality of predators transported to Bethany Reservoir and conducted preliminary analysis to evaluate evidence of black bass depletion in shoreline habitats; it is important to emphasize that predator depletion was not a PRES objective in 2017, but was informative for the 2018 season.
