Watersheds Where TMDLs Are Being Implemented

Stakeholders in the watershed develop implementation plans, or I-Plans, to bring about the pollutant reductions set forth in total maximum daily loads (TMDLs). Both TMDLs and I-Plans are completed for watersheds listed on this page, and stakeholders are actively engaged in working to improve water quality. Projects are listed in alphabetical order by waterway or geographic region name.
Communities Working Together

The TMDL Program works to restore Texas waterways that have limited quality in relation to one or more of their assigned uses, such as recreation, fishing, or healthy aquatic environment.

Title Description
Tres Palacios Creek: A Community Project to Protect Recreational Uses A project to reduce bacteria and protect recreational safety in Tres Palacios Creek. The stakeholders and the TCEQ developed a total maximum daily load (TMDL) and implementation plan (I-Plan), which together are the road map for improving water quality. The TMDL is adopted and the I-Plan is approved.
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.
Upper San Antonio River: A Community Project to Protect Recreational Uses A community project to reduce bacteria levels and protect recreational safety in the river. Stakeholders worked together to develop an approved implementation plan (I-Plan), which together with the adopted total maximum daily loads (TMDLs) is the road map to improving water quality.
Upper Texas Gulf Coast: A Project for Bacteria in Oyster Waters A community project to reduce bacteria in oyster waters. The Department of State Health Services uses levels of certain bacteria as an indicator of the safety of oyster harvesting. 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.
