Background
and Goals

Adams Bayou and Cow Bayou are located in southeast Texas. Their combined watersheds cover almost 250 square miles in the coastal area of the Sabine River Basin. The water flow in the bayous is intermittent, and periods of no flow are very common.

Water quality testing found that bacteria levels in the bayous and their tributaries may pose a health risk for swimmers. Low concentrations of dissolved oxygen in some areas of the creek indicate that conditions are not optimal for aquatic life.

The goals of the project are to:

  • reduce bacteria levels in the bayous to ensure that recreational use is safe, and
  • maintain concentrations of dissolved oxygen and pH in the bayous at levels that will sustain aquatic life.

The TCEQ is working with the Sabine River Authority Exit the TCEQ to determine the measures necessary to improve water quality in the project watersheds.

TMDLs

The commission adopted these TMDLs on June 13, 2007. The EPA approved the TMDLs on August 28, 2007, at which time they became part of the state's Water Quality Management Plan.
