Sampling the river for a TMDL Project
 

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

This page provides information about projects of the TMDL Program organized by major river or coastal basin. 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.
