Lower San Antonio River: A Community TMDL Project to Protect Recreational Uses
at FM 791
Watershed Counties: DeWitt, Goliad, Karnes, Refugio, Victoria
Basin: San Antonio River
In the Lower San Antonio River, Segment 1901, water quality testing found concentrations of bacteria that may pose a health risk for swimmers. Swimming and other forms of recreation in which people come into direct contact with the water are called “contact recreation” in the state’s standards for water quality.
The goal of this project is to reduce bacteria concentrations in the Lower San Antonio River to within acceptable risk levels for contact recreation.
The commission adopted the TMDL on August 20, 2008.
- One Total Maximum Daily Load for Bacteria in the Lower San Antonio River, Segment 1901
- Response to Public Comment on the TMDL
The EPA approved the TMDL on October 20, 2008, at which time it became part of the state’s Water Quality Management Plan.
From time to time, it is necessary to revise TMDLs to account for changing conditions in the watershed, such as new or amended permits, or urban growth, or to correct oversights in the original TMDL report. Revisions to the load allocations in TMDLs are made via the state’s WQMP, which is updated quarterly.
The WQMP provides projected effluent limits for use in planning and permitting activities under the Texas Pollutant Discharge Elimination System (TPDES). The TCEQ reviews all applications for new and amended permits for conformance with applicable portions of the WQMP, including adopted TMDLs.
Revisions to the TMDL are documented in the approved WQMP updates listed below.
In all our projects, we seek opinions and information from stakeholders—people who represent government, permitted facilities, agriculture, business, environmental, and community and private interests in the watershed. All stakeholders are welcome to get involved in developing the strategy to improve water quality. Public meetings about the project are open to everyone.
