Leon River: A TMDL Project for Bacteria

Counties in Watershed: Comanche, Coryell, Erath, Hamilton, Mills
Parameter: Bacteria
Basin: Brazos River
Segment: 1221

Background and Goals

In Leon River below Proctor Lake (Segment 1221) in the Brazos River Basin, 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 is to reduce bacteria concentrations in Segment 1221 of the Leon River to within acceptable risk levels for contact recreation.

See the Texas Water Resources Institute Web site for information about Proper Organic ManagementExit the TCEQ in the Leon River watershed. The Upper Leon River watershed is a designated Conservation Effects Assessment Project (CEAP) Benchmark Watershed. CEAP Benchmark Watersheds will provide in-depth data on the environmental effects of conservation practices at the field-to-watershed scale. In the Leon watershed, environmental concerns are generally associated with the management of animal byproducts and municipal wastewater, as water quality impairments results from runoff and point source discharge contaminated with pathogens and/or nutrients. The CEAP effort in this watershed will focus on agricultural nutrient management.

Proposed TMDL

The public comment period for the TMDL closed on May 5, 2008. The TCEQ held a public meeting to receive comments on April 17, 2008.

Final adoption of this TMDL has been delayed. Proposed revisions to the Texas Surface Water Quality Standards may affect future decisions to recommence with development of this TMDL. Before moving forward, the TCEQ will schedule meetings with stakeholders to discuss options for future actions.

Public Participation

An advisory group has been formed to involve the public in development of the TMDLs. The group includes stakeholders who represent government,permitted facilities, agriculture, business, environmental, and community interests. This voluntary committee provides advice and comment to the TCEQ on its project to restore water quality in the Leon River below Proctor Lake.
