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\u2013riverine interface in the McCloud Arm of Shasta Reservoir 2023 \u2014 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 \u2014 December 1, 2025.
