Surface Water Quality Monitoring Sampling Stations

Text files listing water quality sampling stations for each basin in Texas.

Sampling stations are sites where surface water quality data are collected by the TCEQ and its partner agencies (such as the Clean Rivers Program, US Geological Survey, Texas State Soil and Water Conservation Board, or the Texas Parks and Wildlife Department). The station files provide the location of each sampling station and its identification number.


Choose a basin to download an ASCII text file of the sampling stations in that basin. Once the file is displayed for download, SAVE the file immediately to prevent it from being truncated by Internet Explorer.
