Texas water quality reports

Find the Texas Integrated Report, impaired-water lists, and assessment guidance.

Understand assessment status

The Texas Integrated Report evaluates surface-water conditions against the state's water quality standards. It provides a broader assessment based on monitoring records, rather than a single day's reading.

TCEQ publishes the report on a two-year cycle. Its 303(d) List identifies impaired waters needing a total maximum daily load or other management strategy. The EPA must approve the list before it is final.
