2024 Water Body Assessment by Basin
2024 water quality assessments in PDF for each of Texas’ river and coastal basins.
TCEQ assessed the water quality of all classified water bodies for which sufficient data were available and for unclassified water bodies where a pending regulatory need exists, or where new information may change the standards attainment status.
Each assessment report also includes an integrated level of support—the overall support level for this use, method, or parameter group—that determines whether a water body will be included in Category 5 [the 303(d) List]. These assessments are grouped by basin in the links below.
