Background

The recreational use of Gilleland Creek in northeast Travis County has been impaired by high bacteria concentrations for several years.

To address this impairment, the commission adopted a total maximum daily load (TMDL) in 2007. Stakeholders then developed a TMDL implementation plan, which the commission approved in 2011. This stormwater project will support implementation of the TMDLs.

Project Description

University of Texas personnel will:

• install and operate an automated valve in a stormwater detention basin outlet in the Gilleland Creek watershed and
• determine the valve's effectiveness in reducing the amount of bacteria, sediment, and phosphorus released by the detention basin into the creek.

The goal is a 50% reduction in each of the sampled pollutants. UT will monitor a similar "control" basin without the retrofit for comparison.
