Draft 2004 Water Quality Assessments for Individual Water Bodies

Data available for Draft 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

For each water body assessed, two documents are available. The Fact Sheet is a summary of the assessment, and includes a description of the water body location. The Assessment Data Sheet shows the number of samples collected and how many exceed criteria.
