Overview
General Division Office BuildingEstablished by the Texas Legislature, GBRA was first created in 1933 under Section 59, Article 16 of the Constitution of Texas as a water conservation and reclamation district and a public corporation called the Guadalupe River Authority. In 1935, it was reauthorized by an act of the Texas Legislature (VCS Art. 8280-106) as the Guadalupe-Blanco River Authority.
GBRA provides stewardship for the water resources in its ten-county statutory district, which begins near the headwaters of the Guadalupe and Blanco Rivers, ends at San Antonio Bay, and includes Kendall, Comal, Hays, Caldwell, Guadalupe, Gonzales, DeWitt, Victoria, Calhoun and Refugio counties.
Planning and resource development efforts are carefully coordinated within the broader consideration of regional and statewide water needs in order to fulfill GBRA's primary responsibilities of developing, conserving and protecting the water resources of the Guadalupe River Basin.
Vision Statement

Mission Statement
The Mission of the Guadalupe-Blanco River Authority is to protect, conserve, reclaim and steward the resources of the ten-county District in order to ensure and promote quality of life for those we serve.
