2004 Water Quality Assessments for Individual Water Bodies

Data available for 2004 Texas Water Quality Assessments for each basin.

For 2004, the TCEQ conducted a targeted water quality assessment. A subset of parameters was assessed for targeted segments. Fact and data sheets for segments assessed for 2004 contain both new information and information from the 2002 assessment. Segments that were not reassessed have fact sheets identical to those published in 2002.

The documents linked below are in Portable Document Format (PDF). (Help with PDF.)

Water Body Assessments by River Basin
