The Brays Bayou watershed in southwest Harris County is one of the Houston area’s largest watersheds, stretching 21 miles from its source west of Highway 6 to its junction with the Houston Ship Channel. It is bounded on the south by U.S. Highway 90A, which separates it from the Sims Bayou watershed, and on the north by U.S. Highway 59, which separates it from the Buffalo Bayou watershed (both highways lie atop shallow ridges). Highly urbanized, with a population exceeding 700,000, the watershed encompasses the Texas Medical Center, five major universities, several major parks, and the NRG Park sports complex, home to the Houston Texans, the Houston Livestock Show and Rodeo, and the Astrodome.
The Brays Bayou watershed is the target of the Harris County Flood Control District’s Project Brays, a $500 million effort to reduce the risk of flooding within the watershed. HCFCD provides extensive information about the project on two websites, www.hcfcd.org and www.projectbrays.org.
