Water-use data available from USGS

The U.S. Geological Survey maintains national data bases of water-use information. The data are collected and compiled every five years for each State, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands.

County, State, and national water-use estimates may be downloaded from the National Water Information System Web (NWISWeb) interface, Water Data for the Nation, by selecting the Water Use button or data category pull-down. Data on NWISWeb represent the current best estimates, and may have been revised from previous publications. Data available from the links below generally reflect the published report, and may have been revised in subsequent analysis. Note: watershed data are not available on NWISWeb.

Other files, such as lists of county names, graphics, and charts, are also available for some years.
