Background and Goals
In Elm Creek and Sandies Creek in south central Texas, water quality assessment in 1999 found elevated levels of fecal coliform bacteria and low concentrations of dissolved oxygen. The TCEQ worked with the Guadalupe-Blanco River Authority
and other regional stakeholders to develop a plan to restore the quality of the affected streams. The program's South Central Texas Streams project verified the need to develop TMDLs for the creeks.
Disease-causing bacteria from human and animal waste may threaten public health. People who swim or wade in the creek may be at risk. Oxygen, which dissolves in water, is essential for the survival of aquatic life. While the amount of dissolved oxygen in water fluctuates naturally, various human activities can cause unusually or chronically low dissolved oxygen levels, which may harm fish and other aquatic organisms.
Public Participation
The TCEQ informs stakeholders about this project at public meetings and in print and electronic media.
Meetings about TMDL projects are open to everyone.
