Asotin Creek Summer Steelhead

An icon of the Pacific Northwest, wild steelhead have provided important cultural and economic benefits throughout the region's history. To help conserve and restore this important resource, the Washington Fish and Wildlife Commission adopted a Statewide Steelhead Management Plan that provides a framework for rebuilding wild steelhead runs throughout the state. The statewide plan, approved in March 2008, is designed to guide state fish managers as they work with tribal co-managers and local fish-recovery groups to develop management strategies for steelhead populations in seven specific areas of the state. One of those areas is the Puget Sound region, where NOAA Fisheries listed 44 stocks for protection under the federal Endangered Species Act in May 2007.
