Columbia River hydropower is an economic mainstay of the Pacific Northwest. However, it is well known that the construction of hydropower dams has added anthropogenic pressure to Columbia River salmon populations. Juvenile salmon that pass through powerhouse turbines at large hydropower dams display higher mortality rates than salmon passing through alternative routes; thus at Priest Rapids Dam, a top-spill fish bypass was constructed as a safer alternate downstream passage. To investigate the efficacy of this new passage structure, an acoustic telemetry study was conducted in the spring of 2014 to determine the ability of the bypass to collect and safely …
