Background and Goals
The Tres Palacios Creek (Segment 1501) watershed is located along the Texas Gulf Coast midway between the cities of Victoria and Houston. The creek flows into Tres Palacios Bay, and then into Matagorda Bay. Segment 1501 is the portion of Tres Palacios Creek that is influenced by tidal action, meaning the tidal segment receives freshwater inflows from the watershed and saline water from Tres Palacios Bay.
Since 2006, high concentrations of bacteria, which are found in both human and animal waste, have been observed in the creek. The presence of these bacteria may indicate a health risk to people who swim or wade in the bayou—activities referred to as “contact recreation” in the Texas Surface Water Quality Standards.
The goal of this project is to improve water quality in order to protect recreational uses. Toward that goal, TCEQ has developed a total maximum daily load (TMDL) and worked with stakeholders to develop an implementation plan (I-Plan) to reduce bacteria in Tres Palacios Creek. Stakeholders also developed a Watershed Protection Plan (WPP).
Get Involved
Staff from the Texas Water Resources Institute (TWRI) worked with stakeholder communities, interest groups, and local organizations to distribute information about this project and involve stakeholders in developing the I-Plan for watershed improvement. All public meetings about this project are open to anyone interested. Watch for meeting announcements here and on the TWRI website.
Status of Activities
The TWRI watershed coordinator and stakeholders meet annually to evaluate the progress of their I-Plan and WPP. Tracking of implementation progress allows stakeholders to evaluate actions taken, identify actions that may not be working, and make any changes as necessary.
