Background and Goals
Upper Oyster Creek is located within the Brazos River Basin, immediately southwest of Houston in northern Fort Bend County. Segment 1245, though named Upper Oyster Creek, also includes parts of Jones Creek, Oyster Creek, Flat Bank Creek, a diversion canal, and Steep Bank Creek. Upper Oyster Creek has been highly modified and serves as a portion of a water conveyance system for the Gulf Coast Water Authority.
Water quality testing found that bacteria levels in Upper Oyster Creek might pose a health risk for swimmers. Low dissolved oxygen concentrations in some areas of the creek indicate that conditions are not optimal for aquatic life.
The TMDL Program worked with area stakeholders to develop a plan to improve water quality in the creek. The goal of the project is to reduce bacteria concentrations to within acceptable risk levels for swimmers, and improve conditions to support a healthy aquatic community.
Get Involved
In all its projects, TCEQ gathers opinions and information from people who represent government, permitted facilities, agriculture, business, environmental, and community and private interests in the watershed. Staff from the Houston-Galveston Area Council (H-GAC) have been working with stakeholders to distribute information about this project and involve them in developing the I-Plan for watershed improvement.
All public meetings about this project are open to anyone interested. Watch for meeting announcements here.
Approved I-Plan
The commission approved this stakeholder-developed plan on January 15, 2014.
- Implementation Plan for Two Total Maximum Daily Loads for Dissolved Oxygen and One Total Maximum Daily Load for Bacteria in Upper Oyster Creek
- Response to Public Comment on the I-Plan
Adopted TMDLs
Dissolved Oxygen TMDLs
On July 28, 2010, the commission adopted the TMDLs for dissolved oxygen. The EPA approved the TMDL on Sept. 21, 2010, at which time it became part of the state’s Water Quality Management Plan.

For WQMP updates prior to 2014, use the TRAIL Search engine as outlined below. The main search box on the page will only conduct a simple search with no exclusionary parameters and should not be used.
- First, limit your search to TCEQ only. Do this via the advanced search feature on the left of the page. To limit a search to TCEQ content, enter www.tceq.texas.gov or www.tceq.state.tx.us into the “From the Host” search box.
- Refine your search to narrow down results. The other search boxes on the left of the page allow for search terms to be included, excluded, or used in an exact phrase search. Date ranges can be used as well.
