Water Quality Assessment, Planning, and Implementation Activities by Watershed

The following is a subset of Texas waterbodies that are (or have been in the recent past) listed on the Texas Water Quality Inventory and 303(d) List. This subset includes all of the "concerns" or "impairments" in which the Statewide Resource Management (SRM) group of the TSSWCB has reason to believe may be caused by agricultural and/or silvicultural nonpoint source pollution to an extent which is sufficient to justify expenditure of agency resources.

For additional information about this table, please refer to the Legend.
