Background
and Goals
In seven streams in the San Antonio, Brazos, and Guadalupe River
Basins, 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 was to evaluate the need for TMDLs to
reduce bacteria concentrations to within acceptable risk levels in
the affected segments—the Medina River below the Medina
Diversion Lake (Segment 1903), the Leon River below Proctor Lake
(Segment 1221), Peach Creek (Segment 1803C), San Antonio River
(Segment 1901), Salado Creek (Segment 1910), Walzem Creek (Segment
1910A), and Upper San Antonio River (Segment 1911).

Phase I:
Evaluation
Additional data collected from the Medina River below the Medina
Diversion Lake (Segment 1903) indicated that the segment is meeting
the applicable criteria; consequently, no TMDL will be developed
for the segment unless conditions change. Four projects have been
formed to develop TMDLs for the other six segments (see below).
Phase II: TMDL Development
Because of the geographic separation among the watersheds, the
TCEQ formed four subprojects to develop the necessary TMDLs. Get
information on development of the TMDLs by following the links
