Colorado River Basin: 2004 Assessment

List of assessment and fact sheets for different water body segments in the Colorado River Basin for 2004.

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. Fact sheets and summary sheets where there is new information are indicated by the icon, with the exception of those that were reassessed in 2004 but had only category or rank changes.

The files provided for download on this page are in Portable Document Format (PDF). (Help with PDF.)

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