Lake Levels USA tracks 34 lakes and reservoirs in Washington using U.S. Bureau of Reclamation (RISE), U.S. Geological Survey (Water Data for the Nation). Of the 32 with a current 7-day trend, 7 rose and 20 fell by more than 0.05 ft. Latest data: Oct 25, 2026. Elevations from different gauges use different datums, so compare each lake with its own history, not with other lakes.
