USGS Data Collection Network

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.

You can also ask questions and request data or reports from our Public Information Officer.
