Irrigation Water Use Estimates

The Texas Water Development Board (TWDB) is legislatively directed to plan for, and to assist financially, the development and management of the water resources of Texas. The usefulness of the TWDB's water planning and funding activities is dependent upon the accuracy and completeness of the information that water users provide. To this end, the TWDB annually collects and maintains accurate information concerning the current use of water.

TWDB staff is responsible for providing data to assist regional planning groups in planning for future water supply and demand, including these agricultural irrigation estimates. TWDB does not have the authority to require producers to report actual irrigation water use.

TWDB staff annually estimates agricultural irrigation water use for every county in the state. Irrigated acreage information is obtained from U.S. Department of Agriculture - Farm Service Agency records and local sources when available. Surface water irrigation diversion releases are provided by Texas Commission on Environmental Quality regional Watermasters. Groundwater conservation districts assist by reviewing the estimates and suggesting revisions based on local expertise.Learn more about this process by reading our Water Use Estimation Methodology.

For more information on this process visit the TWDB Water Use Survey which contains all of the Historical Water Use Estimates, as well as data specific to the Historical Agriculture Irrigation Water Use Estimates.
