Salmonid and Steelhead Population Summary (SPS) and Viable Salmonid Population (VSP) in the Pacific Northwest: Salmonid and Steelhead Population Abundance Summary from 1949 to 2010 for Washington, Oregon, and Idaho (NCEI Accession 0280945)

The Northwest Fisheries Science Center's (NWFSC) Salmon Population Summary (SPS) database provides public access to demographic data compiled for ESA-listed salmonid populations as part of the NWFSC's technical recovery planning efforts. The database contains data collected by co-managers (WDFW, ODFW, IDFG, and Tribes) and compiled in cooperation with NWFSC staff for: spawning abundance, age structure of wild spawners, fraction of natural spawners that are of wild origin, and the reduction in spawning abundance due to harvest. For some populations, additional data fields are also available. Abundance of ESA-listed salmonids.
