Sampling water quality for a
TMDL Project

Texas has 25 major basins, including the extraterritorial waters of the Gulf of Mexico over which the state has jurisdiction. See Hydrography Maps and Data for geographic and other information about the major river basins.

The TMDL Program works with stakeholders to restore rivers, lakes, and estuaries that have limited quality in relation to one or more of their assigned uses, such as recreation, fishing, or healthy aquatic environment.
