About The Authority

San Antonio River Authority

In 1917, the voters of Texas, recognizing the necessity of developing and conserving the State’s water resources and inspired by devastating floods of 1913 and 1914, passed a Constitutional amendment allowing the Legislature to create special purpose political subdivisions of the State to serve regional areas, generally coincidental with river basins and to be generally known as river authorities.

San Antonio River Authority, created in 1937, is one of many such active river authorities in the State of Texas. Its jurisdiction covers 3,658 square miles—all of Bexar, Wilson, Karnes and Goliad Counties.

Our Leadership


A 12-member Board of Directors governs the San Antonio River Authority (River Authority). Six directors are elected from Bexar County and two are elected from each of the three other counties with each elected member serving six years. Policies established by the Board are executed by the management organization under the direction of a General Manager appointed by the Board.

Taxing Authority

The San Antonio River Authority has the statutory authority to impose an ad valorem tax for use in planning, operations and maintenance activities only. Its tax is statutorily limited to two cents per $100 of assessed property valuation. The proposed ad valorem tax rate is estimated to be $0.01842 per $100 assessed property valuation. The average annual tax is $46.24. The adopted FY 2022-2023 budget is $371.6 million.
