Upper Oyster Creek: Implementing TMDLs to Protect Aquatic Life and Recreational Uses

A project to reduce bacteria and increase dissolved oxygen to protect recreational and aquatic life uses. The TMDLs are adopted and the I-Plan is approved. Together, they provide the road map to improved water quality.

Counties: Fort Bend
Parameters: Bacteria, dissolved oxygen
River Basin: Brazos River
Segment: 1245

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 is working 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.

Recreational Use Attainability Analysis

The TCEQ Standards Team is also working in the watershed on a Recreational Use Attainability Analysis (RUAA) for the Fort Bend County area of the watershed. See information about the RUAA on our website, or at contact our Standards Team by e-mailing standards@tceq.texas.gov or calling 512-239-6682.

Adopted TMDLs

Dissolved Oxygen TMDLs

On July 28, 2010, the commission adopted the TMDLs for dissolved oxygen.

The EPA approved the TMDL on September 21, 2010, at which time it became part of the state’s Water Quality Management Plan.

Updates

Updates are made to account for changing conditions in the watershed, such as new or revised wasteload allocations, permits that have been canceled or have expired, or changed facility names.
