Background and Goals
Data assessed in 2002 showed that 14 bay segments in three geographic regions (see “Project Overview” above) were not safe for harvesting shellfish because of elevated bacteria concentrations. The use of waters for oyster harvesting—called the “oyster waters use” in the state’s standards for surface water quality—is the most commonly impaired use among Texas bay and gulf waters.
Microorganisms from human and animal waste may endanger public health by contaminating oysters and other shellfish, making them unsafe to eat, especially since some shellfish are often eaten raw.
To address the impaired oyster waters use, the TCEQ’s TMDL Program initiated a project to evaluate the affected waters and develop a strategy for action. This project was completed in August 2006.
To involve area stakeholders in the project, the TMDL Program worked with the existing estuary program forums of the Galveston Bay Estuary Program and the Coastal Bend Bays and Estuaries Program. Both groups include regional stakeholders who represent a wide variety of interests, such as agriculture, industry, government, and civic groups.
- Bays in the Upper Texas Coast
After analysis, the work group determined that TMDLs were needed for this group of bays. Read about the Upper Coast Oyster Waters TMDL project to find out more.
- Bays in the Middle Texas Coast
The Middle Texas Coast Oyster Waters project was initiated to determine the extent and severity of the bacteria impairments. For more information about the project, e-mail email@example.com or call 512-239-6682.
- Bays in the Lower Texas Coast
The Copano Bay project, which also includes Port and Mission Bays, was initiated to determine the best course of action for restoring the oyster waters use in bays of the lower Texas Coast.
