Upper Oyster Creek

This is a project to reduce bacteria and increase dissolved oxygen to protect recreational and aquatic life uses in Upper Oyster Creek. The total maximum daily loads (TMDLs) were adopted and the implementation plan (I-Plan) has been approved. Together, they provide the road map to improved water quality.

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.

UPDATE

H-GAC invites residents, local governments, businesses, and non-profits in the Upper Oyster Creek watershed within Fort Bend County to attend the annual stakeholder meeting 1–3 p.m. on Tuesday, August 29, 2023.  

The meeting will be held in-person at:

City of Sugar Land Town Square (City Hall)
Cane Room
2700 Town Center Blvd N. 
Sugar Land, TX 77479
(281) 275-2900

The purpose of the meeting is to discuss water quality issues that potentially affect communities in the watershed, including all or portions of the cities of Sugar Land, Missouri City, Stafford, and Fulshear. Residents and organizations are invited to participate in this meeting to review and discuss progress implementing the bacteria reduction plan and improvements to dissolved oxygen.

All public meetings about this project are open to anyone interested. Watch for meeting announcements here.

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. Updates are made via the state’s Water Quality Management Plan.
