Louisiana Water Use Program

Louisiana has a total land and water area of 48,000 mi² and abundant water resources are throughout the State. Every day, large amounts of water are withdrawn from natural sources for public supply, industrial, power generation, rural domestic, livestock, irrigation, and aquaculture uses. Water-use data are essential to appraise the effects of present use and plan the future use of Louisiana's water resources. The U.S. Geological Survey, in cooperation with the Louisiana Department of Transportation and Development, has collected and published water withdrawal and use information on a five year basis since 1960.

Note:

Values in the tables represent the best estimate of what was known at the time of data collection. As additional resources become available some revisions may be made in order to correct errors and to reflect improved understanding. Therefore, the present dataset viewed in the tables is evolving rather than permanently fixed.
