Sampling Data Query, Surface Water Quality Monitoring

Use of the data files requires a certain knowledge of the file structures and protocols of the state's surface water quality monitoring program.

If you want to obtain surface water quality data on specific water bodies in report format, please call the TCEQ's Data Clearinghouse at 512/239-DATA, (3282).


There are two files associated with the data. The sampling event data file (EVENT file) provides the station ID, sample date and time, sample depth, and the entity that did the sampling. The result data file (RESULT file) provides the monitoring parameter (STORET) code and measurement information.

The data is available from 01/01/1968 to the present, and is updated the first week of every month.

The following documents explain the structure of the files available for download.
