Water Quality

Mill Creek was identified on the state’s most recent list of impaired waters (2012) due to elevated levels of bacteria. This list, known as the Texas Integrated Report 303(d) list, is compiled every two years using the most recent 7 years of water quality sampling data collected through the Texas Commission on Environmental Quality (TCEQ) Clean Rivers Program. The Texas Commission on Environmental Quality has been monitoring Mill Creek since 1974.

Additional Water Quality Monitoring

In support of the development of a Watershed Protection Plan for Mill Creek, Texas A&M AgriLife Extension partnered with the Houston-Galveston Area Council to collect additional water quality data throughout the watershed. Nine locations were identified for additional sampling on a monthly basis (e.g. ambient sites) through June, 2015. In addition to the monthly sampling regime, samples were collected at each of the ambient monitoring sites as well as 4 additional sites (e.g. storm-water sites) during 3 wet-weather periods. Wet-weather periods were identified by the presence of adequate flow at the four storm-water sites.
