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

Published by California Department of Water Resources | State of California | Catalog Last Checked: March 28, 2026 at 07:38 PM | Dataset Last Updated: March 25, 2026 at 03:39 PM
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.
