La 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 Every day, large amounts of water are withdrawn from natural sources for public supply, industrial, power generation, rural domestic, livestock, irrigation, and aquaculture uses.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. In 2012, the USGS, in cooperation with the Louisiana Department of Natural Resources, began estimating water withdrawals in Louisiana on an annual basis. Data collection methods are discussed in the report, Water Use In Louisiana, 2010.


Values in the tables represent the best estimate of what was known at the time of data collection. As additional information becomes available, some revisions may be made in order to correct errors and reflect an improved understanding of withdrawals. Therefore, the present dataset viewed in the tables is evolving rather than permanently fixed. Modified 10/2/2015.
