    • Salmonid and Steelhead Population Abundance Summary from 1949 to 2015 for Washington, Oregon, and California

    Metadata Updated: May 24, 2025

    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. The data correspond to the populations identified by the NMFS Technical Recovery Teams, and are used in part to assess population and ESU-level recovery criteria for many listed ESUs. Most importantly, this data is critical for informing 5 year ESA salmon reviews, and makes 5 year status review data available to the public.
