Carters Creek Watershed: Implementing TMDLs to Protect Recreational Uses

A project to develop and implement TMDLs to reduce bacteria levels and protect recreational uses of the creek. The adopted TMDL and the approved I-Plan combined are the road map to improving water quality in the creek.

County: Brazos
Parameter: Bacteria
River Basin: Brazos
Segment: 1209C, 1209D, 1209L

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.

Get Involved

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) Exit the TCEQ site is coordinating continued stakeholder involvement during implementation.

Meeting Records

The Texas Water Resources Institute (TWRI) coordinated stakeholder involvement and the drafting of the I-Plan. Records of stakeholder meetings Exit the TCEQ site 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.

Status

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.

Grant Funded Projects to Support the I-Plan

  • Carters Creek TMDL Data Project, collecting additional water quality data to determine when and where bacteria levels are higher or lower in the creek.
  • Carters Creek Implementation Project, survey the watershed to identify and map possible sources of bacteria pollution and provide more robust information for determining or verifying good strategies for improving recreational conditions.

TMDLs and Implementation Plan

On August 22, 2012, the commission adopted the TMDLs for Carters Creek watershed and approved the stakeholders’ Implementation Plan.

On September 27, 2012, the EPA approved the TMDLs, at which time they became part of the state’s Water Quality Management Plan.
