This report describes the findings that have resulted from the effort to create a proposed Nez Perce Tribal Hatchery (NPTH) in northern Idaho. This effort has been undertaken because of low population densities of salmon in the Clearwater and Salmon River Basins. The Northwest Power Planning Council (Council) has approved the NPTH concept. For the NPTH to proceed, the Council must approve a master plan and amend the Columbia Basin Fish and Wildlife Program (CBFWP). Requirements of the National Environmental Policy Act (NEPA) also must be met. The goals of NPTH are to: (1) develop, increase, and reintroduce natural populations of spring, summer, and fall chinook in the Clearwater and Salmon River Basins; (2) sustain long-term preservation and genetic integrity of target fish populations; (3) keep the ecological and genetic impacts of nontarget fish populations within acceptable limits; and, (4) provide harvest opportunities for both tribal and non-tribal anglers.
