Water Quality Monitoring on Mud Creek

The Authority’s Environmental Staff has already begun monitoring and testing water quality in the Mud Creek Subwatershed in anticipation of the reservoir construction. It is important to know in advance if there are sources of pollution so steps can be taken to correct them prior to reservoir completion.

The testing is being funded by the Texas Commission on Environmental Quality under the Clean Rivers Program which is operated by the Authority in this basin. The program has set up five additional stations to look for a variety of pollutants. In 2008, the Texas Water Development Board awarded a grant in the amount of $97,434.00 to fund additional water quality sampling in the Mud Creek watershed. The purpose of the testing was aimed at determining water quality in preparation for designing water treatment systems for the production of potable water for the participants of Lake Columbia.
