USGS Washington Water Science Center
WaterWatch - Washington Current Streamflow Conditions
The U.S. Geological Survey currently operates about 390 data collection sites in Washington for acquiring information on surface water (USGS Podcast: Streamgages), ground water, water quality, and precipitation. About 170 of the sites with satellite telemetry provide real-time data via GOES satellites and downlinks, which enables the posting of data to the Web for public dissemination.
The USGS has also collected surface-water data at nearly 1,000 historical sites. At some of these sites, continuous water-quality data are also available. The USGS database has ground-water data for about 90,000 sites. We also have water use data for every fifth year from 1985 to 2005.
