This Contract was a continuation of RCO projects #15-1191 and #20-1930. The tracking data gathered in Phase 1 (15-1191) of this assessment indicated that up to 50% of the juvenile steelhead that travel to the Hood Canal Bridge do not survive past it. Phase 2, (20-1930) designed solutions to reduce steelhead mortality at the Bridge. During Phase 2.2, the Sponsor worked with qualified vendors to fabricate, deploy, and operate a fish passage device at the Hood Canal Bridge (Task 1 & 2); and assess the associated change in mortality of juvenile steelhead (Task 3). The project is a fish passage assessment project, where a temporary fish passage structure designed to alter the path of salmonids and the flow of water was installed during one spring outmigration season during the project period. The temporary structure was removed and stored on land at the conclusion of Phase 2.2. Juvenile steelhead were tagged, and acoustic telemetry methods were used to measure their relative survival during control and treatment periods with the fish passage device activated and deactivated. Videography footage was taken of the project activities that will eventually be used for a public education tool (Task 4). In partnership with Washington Department of Fish and Wildlife, the sponsor procured services to test non-lethal predator deterrent and assessment of its effectiveness (Task 5). This project supports nearshore habitat used by ESA-listed and non-listed salmonids including, steelhead, Chinook, fall chum, summer chum, and coho. The legislature has appropriated funding for the continuation of this project through a direct appropriation of the FY2023 and FY2025 operating budget.
