Water Use in the United States
Science Center Objects
The USGS works in cooperation with local, State, and Federal agencies to collect water-use information, then compiles these data to produce water-use information aggregated at the county, state, and national levels. Every five years, data at the county level are compiled into a national water-use data system and State-level data are published in a national circular, Estimated Use of Water in the United States.
The National Water Use Science Project, part of the National Water Census, is responsible for compiling and disseminating the nation's water-use data. The USGS Water-Use Data and Research program seeks to develop improved water-use data through agreements with State water-resources agencies.
