    • Baseflow Fractions at USGS Gages for Water Years 1981 to 2020 (ver. 2.0, October 2022)

    Metadata Updated: November 12, 2025

    Simulated daily baseflow was summed from water year 1981 to 2020 and divided by observed streamflow at 13,208 sites where US Geological Survey operated a streamflow gage and calculated daily streamflow for at least 300 days. Days with negative flows (tidal systems) are not included.
