The U.S. Geological Survey, in cooperation with other government agencies, stakeholder groups, and private entities, is maintaining a water-quality database for selected study areas in Colorado. This database combines water-quality data from the USGS National Water Information System (NWIS) and the U.S. EPA STORET databases. Additional relevant datasets from a variety of other sources also are being included. These data can be retrieved by using this website — begin by selecting a study area of interest.
