Tabular datasets containing information pertaining to fish caught during trapping effort in the Deshka River between 2019 and 2024 to sample juvenile salmon. These data collected from the field are used to assess effort and were acquired using a Survey123 data acquisition application.

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.

Collection of datasheets (pdf files) containing raw data collected during baited minnow trap study in 2021.

Tabular data pertaining to biometrics, histology, genetics, and information relating to location and date of capture of Chinook salmon caught in the Yukon River for Ichthyophonus project.

Tabular dataset containing species, count, and ReachID for juvenile salmonids and other fish species captured in minnow traps from Campbell Creek. Additionally, tabular dataset describing spatiotemporal and environmental factor data for each trap site during the capture of juvenile salmonids in Campbell Creek.

Tabular dataset of data collected from chinook salmon smolt trapping on the Chena River in May and June of 2017-2019. Trapping took place between the East end of the Fort Wainwright airfield (N 64.831952, W -147.571279) and adjacent to Chena Marina (N 64.81065, W -147.89908) in 2017, between Hamilton Acres (N 64.839650, W -147.681000) and Pikes Landing (N 64.830467, W –147.848750) in 2018, and between Nordale Road Bridge (N64.846536, W -147.410418) and Grahel Park (N 64.845831, W –147.706114) in 2019. This dataset contains the biometric and tagging data related to captured Chinook salmon.

Tabular dataset containing age, sex, and length data for Chum, Chinook, and Sockeye salmon. Sex was determined externally using visual clues such as snout shape and size. Length was measured from fork to mid-eye with a measuring board to the closest 5 mm. Strata refers to the potion of the run the fish was sampled during. Strata data is based on the size of the population rather than date since the salmon run does not start on one specific date year by year. Scales were also taken and placed on a gum card for age assessment. One scale was taken for all sampled Chum salmon and three scales were taken for all sampled Chinook salmon.
