Historical Water Use Estimates

These estimates are produced using information from the annual Water Use Survey and water use estimates for the irrigation, livestock and mining categories. Summary estimates for 1999 and earlier are static historical estimates. Data reports for 2000 and later are generated directly from the TWDB's Water Use database and reflect the most current and accurate data available to the agency. Periodically, the data reports are refreshed to include any new or corrected information. Please note that as of August 2014, the historical estimates for both water use and groundwater pumpage have been updated to reflect changes primarily for manufacturing, mining and power water use estimates and irrigation groundwater pumpage estimates. Reuse volumes are only included in the data reports for 2015 and later.

Please read Frequently Asked Questions for more information on Water Use Survey estimates and how they are derived.

Supplemental Information

Note: Historical Water Use Estimates are specific to the location where surface and groundwater is used by end users, whereas Historical Groundwater Pumpage Estimates are specific to the location where groundwater is pumped from the aquifer. The location of use may not necessarily be the same as the location of the source due to water transfers or purchases from other geographic areas.
