Rowlett Creek Watershed

The Rowlett Creek watershed is a major contributor of flow to Lake Ray Hubbard, a critical water supply reservoir for the region. The watershed includes multiple cities in Dallas and Collin Counties. Rowlett Creek was first added to the 303d list for bacteria/e. coli in the 2014 Texas Integrated Report on Water Quality. It has also been listed as a water body of concern due to elevated levels of nitrate.
