Book excerpt: Steelhead trout Oncorhynchus mykiss in the Snake River basin are the focus of a variety of harvest and conservation programs. Information needs for management of Snake River steelhead within this large and complex arena can be systematically addressed using a run reconstruction model. The purpose of this work is to summarize data describing the abundance of steelhead crossing Lower Granite Dam (LGR) and estimate the fishery-related impacts on both hatchery and wild steelhead as they migrate to their natal or release area in the Snake River basin. The model provides an analytical tool whose outputs can be used to bridge gaps in the existing data using reasonable assumptions in a structured manner. Representatives from the anadromous fishery management agencies within the Snake River basin collaborate to complete a run reconstruction for Snake River steelhead, which have been modeled since 2011. In this report our objective was to estimate the disposition of steelhead within the Snake River basin from July 1, 2019 to June 30, 2020 (spawn year 2020). After adjusting for nighttime passage and fallback, we estimated 9,771 wild steelhead, 2,449 unmarked hatchery steelhead, and 23,646 adipose-clipped hatchery steelhead passed LGR on the Snake River during spawn year 2020. Fishery-related steelhead mortality in the Snake River basin upstream of Ice Harbor Dam totaled 390 wild, 197 unmarked hatchery, and 8,864 marked hatchery fish. An additional 158 wild, 426 unclipped hatchery, and 7,069 clipped hatchery fish were collected for broodstock, culled, or donated to food banks (only hatchery fish). Snake River wild steelhead stocks experienced total losses of 21.8% between Bonneville Dam and Ice Harbor Dam. Fishery-related losses across all Major Population Groups of wild steelhead within the Snake River basin was 3.5%. Model results will allow Snake River basin managers to evaluate fishery impacts on wild steelhead, evaluate hatchery program performance, and help evaluate the performance of the Snake River steelhead evolutionarily significant unit.
