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 total maximum daily loads (TMDLs) are adopted and the implementation plan (I-Plan) is 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

The Houston-Galveston Area Council  is coordinating public participation related to implementation of the TMDLs. Meeting records about the implementation plan and annual reports on implementation progress are available on their Upper Oyster Creek TMDL Implementation website Exit the TCEQ. Meetings about the project are open to everyone.

Approved Implementation Plan

The commission approved this stakeholder-developed plan on January 15, 2014.

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.

Bacteria TMDL

The commission adopted this TMDL for bacteria on August 8, 2007. The EPA approved the TMDL on September 28, 2007, at which time the TMDLs 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.
