TMDL and Implementation Plan for the Guadalupe River above Canyon Lake
River Basin: Guadalupe
- Implementation Plan
On August 31, 2011, the commission approved the plan to implement the TMDL for bacteria.
The state is coordinating a watershed protection plan with the TMDL implementation plan to improve water quality in the Upper Guadalupe River. The Upper Guadalupe River Authority is coordinating stakeholder participation.
The implementation strategy includes the following actions:
- Reduce bird feeding at Louise Hays Park and Kerrville-Schreiner Park
- Install bird exclusion and deterrent devices on the SH 16 and LP 534 bridges over the water
- Manage the waterfowl population at Louise Hays Park and Kerrville-Schreiner Park
- Reduce human contributions through ongoing lateral sewage-line replacement, sewer inspection, and rehabilitation, and ongoing review and registration of plans for septic systems
- Implement an education program for pet owners and install pet-waste stations at public parks
- Reduce contributions from general urban runoff through street sweeping, river cleanups, and stormwater education programs
- Monitor and report E. coli concentrations from wastewater-treatment facilities

On July 25, 2007, the commission adopted the TMDL.

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.
