This dataset was updated in January 2013 to make use of newer watershed boundaries that better depict the freshwater range of Pacific salmon and steelhead under NOAA Fisheries' jurisdiction. They are provided for general reference only and do not constitute a legal description of any species listed under the U.S. Endangered Species Act.Throughout the West Coast, 11 species of steelhead are protected under the Endangered Species Act. The West Coast Region works with its partners to protect, conserve, and recover steelhead by addressing the threats these animals face and by restoring the habitat on which they depend.
