Estimated Use of Water in the United States
County-Level Data for 2010
The current best estimates of county, State, and national water-use data may be downloaded from the National Water Information System Web (NWISWeb) interface, Water Data for the Nation. Data on NWISWeb may have been revised from previous publications such as Circular 1405.
These data files present water-use estimates by county for the United States, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands which support the State-level water-use estimates published in USGS Circular 1405, Estimated Use of Water in the United States in 2010. Publication data files for other 5-year reports are also available.
The summary of category changes and the water-use terminology page may also be helpful.

A file of all county-level data for the United States is provided in MS Excel format and as a tab-delimited ASCII file. (The use of trade names is for identification purposes only and does not constitute endorsement by the U.S. Geological Survey.) Microsoft has a free viewer program for Microsoft Excel files for those who do not own a copy of Microsoft Excel. No individual State data files are provided. Data for individual State or for user-selected groups of counties can be retrieved from NWISWeb.
A file of the formatted tables at the State level as presented in the Circular is provided in Excel format.
Data dictionary information is provided in Excel comment fields attached to each column heading and to cells containing FIPS codes, and on a worksheet in the Excel file. A separate data dictionary also is available.
