Goal: Achieve anadromous fish inriver migration and passage survival that approximates natural survival during inriver migration Objective: Achieve the four juvenile and adult fish passage performance standards consistent with the most recent NOAA Fisheries FCRPS Biological Opinion. As of 2009 these consist of: Annually achieve juvenile fish dam passage performance standards at each Snake River (SR) and lower Columbia River dam: ESU Juvenile Standard spring Chinook and steelhead Achieve at least 96 percent (spring migrants) dam passage survival Snake River fall Chinook Achieve at least 93 percent subyearlings (summer migrants) dam passage survival Annually achieve the adult fish performance standards for each of the salmon and steelhead evolutionarily significant units (ESU) listed below for the specified reaches between Bonneville Dam (BON), Lower Granite Dam (LGR), and McNary Dam (MCN): ESU Adult Standard Reach SR Fall 81.2% BON to Chinook LGR SR Spring 91.0% BON to – Summer LGR Chinook SR Sockeye Use SR spring/summer Chinook BON to salmon and steelhead as surrogate LGR until a standard is developed.
