Background and Goals
High concentrations of bacteria such as E. coli and fecal coliform, which are naturally found in both human and animal waste, may indicate a health risk to people who swim or wade in the creek—activities called “contact recreation” in the Texas Surface Water Quality Standards. Water quality testing has indicated that concentrations of bacteria in Carters, Burton, and Country Club creeks are sometimes higher than the criteria in the Standards.
The watershed of Carters creek is in Brazos County, and covers about 57 square miles. Land use in the watershed is heavily urbanized in the upper reach where Carters Creek originates in Bryan/College Station, and becomes more rural in the lower reach. Country Club Branch flows into Burton Creek, which in turn flows into Carters Creek. These tributary watersheds are almost entirely urbanized.
The goal of this project is to reduce bacteria concentrations to within acceptable levels for contact recreation through development of total maximum daily loads and a plan to implement them. A TMDL is like a budget for pollutants. It determines the amount of a pollutant (or load) that a water body can receive and still support its designated uses.
The total load is then allocated among the categories of pollution sources within the watershed, and stakeholders develop a plan with measures to reduce pollutant loads. I-Plans are carried out by stakeholders over a period of several years.
Stakeholders discuss progress at meeting in August 2013
In all its projects, the TCEQ seeks opinions and information from people who represent government, permitted facilities, agriculture, business, environmental, and community and private interests in the watershed. The TCEQ solicits advice from the public at meetings and through notices in print and electronic media. The Texas Water Resources Institute (TWRI) is coordinating continued stakeholder involvement during implementation.
The Texas Water Resources Institute (TWRI) coordinated stakeholder involvement and the drafting of the I-Plan. Records of stakeholder meetings held during development of the TMDLs and I-Plan are available on their website.
Status and Activities
The Implementation Plan documents measures stakeholders are using to reduce bacteria loads. Their strategy includes the following actions:
- Coordinate and expand existing water quality monitoring in the watershed and conduct a survey of bacteria sources.
- Determine the feasibility of modifying tax valuation requirements for agricultural lands; quantify expected water quality impacts of modifications and/or of transitioning from agriculture to wildlife valuations.
- Work to improve OSSF management to ensure proper system functioning.
- Implement sanitary sewer overflow (SSO) initiatives as appropriate.
- Implement voluntary best management practices (BMPs) on agricultural or undeveloped properties.
- Encourage and promote future development and redevelopment that will mitigate adverse water quality impacts.
- Implement Stormwater Management Programs (SWMPs) for individual cities.
- Monitor bacteria concentrations in effluent from WWTFs according to individual permit requirements.
November 21, 2013. Riparian and Stream Ecosystem Workshop – College Station. The program will concentrate on the nature and function of stream and riparian zones, as well as the direct economic impacts and benefits from maintaining healthy zones. Carters Creek will be examined during the workshop.
In 2013, stakeholders met in May and August to discuss implementation of the TMDLs.
Annual tracking of implementation progresss allows stakeholders to evaluate actions taken, identify actions that may not be working, and make any changes as necessary.

TMDLs and Implementation Plan
On August 22, 2012, the commission adopted the TMDLs for Carters Creek watershed and approved the stakeholders’ Implementation Plan.
- Three Total Maximum Daily Loads for the Carters Creek Watershed
- Implementation Plan for Three Total Maximum Daily Loads for Bacteria in the Carters Creek Watershed
On September 27, 2012, the EPA approved the TMDLs, at which time they became part of the state’s Water Quality Management Plan.
