Programs that Assess and Protect Water Quality

Programs that monitor, assess and report on water quality, and are involved in watershed protection and restoration.

Assessing and Reporting Water Quality

Each of the partner agencies that participate in the Clean Rivers Program maintains a website that includes an annual Basin Highlights Report, and, every five years, a Basin Summary Report detailing historical water quality data.  The TCEQ uses the data generated by the CRP, TCEQ Region Offices, and other water quality monitors around the state for a variety of purposes, including statewide assessment reports.

The TCEQ's Surface Water Quality Monitoring (SWQM) Program compiles information on the status of water quality for the State of Texas. The SWQM section of the TCEQ’s Web site includes:

  • reports that assess water quality to determine if all designated uses are being attained,
  • guidance that details the methods used to assess the state’s water bodies, and
  • procedural manuals that describe how field measurements and water samples are collected.

Watershed Protection and Restoration

Two other important watershed management programs are the Nonpoint Source Program and the Total Maximum Daily Load (TMDL) Program

The Nonpoint Source Program at the TCEQ takes the lead in the state to prevent and reduce nonpoint source pollution from urban and other nonagricultural sources. The TSSWCB Exit the TCEQ fulfills those responsibilities for agricultural and forestry lands. Both agencies administer grant funds that may be used for these efforts.

The TMDL Program conducts modeling activities to identify the loads associated with pollutant sources in the watershed, and develops implementation plans to improve water quality in impaired water bodies in Texas. Find out more about TMDL projects under way or completed by the TCEQ.

Nonpoint Source Pollutants

Nonpoint source pollutants—contaminants that are not discharged from a single, readily identifiable source, which are carried to streams, lakes, and bays by runoff and washoff.
