Gilleland Creek: Implementing a Plan to Protect Recreational Uses

The goal of this current project is to keep recreation safe in Gilleland Creek by reducing bacteria levels. The adopted TMDL and the approved I-Plan combined are the road map to improving water quality in the creek.

Water quality testing found that bacteria concentrations are elevated in Gilleland Creek, located in northeastern Travis county. High bacteria concentrations might pose a risk to people who swim or wade in the creek. Swimming and wading are called “contact recreation” in the state’s standards for water quality; the term refers to all recreation in which people are likely to swallow natural waters.

The goal of this project is to reduce bacteria concentrations to within acceptable risk levels for contact recreation.
