Texas Integrated Report of Surface Water Quality

Formerly called the "Texas Water Quality Inventory and 303(d) List," the Integrated Report evaluates the quality of surface waters in Texas, and provides resource managers with a tool for making informed decisions when directing agency programs. The Integrated Report is prepared pursuant to requirements in Clean Water Act Sections 305(b) and 303(d).

The Texas Integrated Report of Surface Water Quality describes the status of Texas’ natural waters based on historical data. It identifies water bodies that are not meeting standards set for their use in a section called the 303(d) list. 

The Texas Integrated Report satisfies the requirements of federal Clean Water Act Sections 305(b) and 303(d). The TCEQ produces a new report every two years in even-numbered years, as required by law. The 303(d) List must be approved by the EPA before it is final.

An advisory group works with the TCEQ on biennial reviews of the “Guidance for Assessing Texas Surface Water Quality.”
