Historical Water Use Estimates

These estimates are produced using information from the annual Water Use Survey and water use estimates for irrigation, livestock, municipal, manufacturing, mining and steam-electric power 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. Note: periodically, the data reports are refreshed to include any new or corrected information. Reuse volumes are only included in the data reports for 2015 and later.

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.
