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, and

Upcoming Clean Up

Come out on Saturday, April 24, 2021 and help clean up the Meyergrove Stormwater Detention Basin, located just inside Loop 610 between Brays Bayou and N. Braeswood Boulevard.

Linked below are several fantastic fact sheets and PDFs that have been created by local and regional trash clean-up entities that provide excellent guidance for coordinating a cleanup with volunteers. The American Rivers Handbook and Waste Disposal Tips have a lot of great checklists for supplies and what to expect and wear. The Average Weight Fact Sheet will help volunteers and team leads estimate how much litter they pick up. Both Keep Texas Beautiful’s Individual Clean Up Guidance and PPE Litter Clean Up Guidance provide great recommendations on keeping volunteers safe while cleaning up discarded Personal Protective Equipment (PPE) as well as safe removal of single use gloves.

Because every piece counts, we require all participants (or team leads) to complete and submit Bayou Preservation Association’s Litter Lowdown report. If needed, you can also print the form and write down cleanup results to report later. For help estimating weight, check out American Rivers’ Average Weight Fact Sheet.

**Before participation, ALL volunteers MUST complete this waiver and return it via email to our Director of Philanthropy and Engagement, Branwen Ranck, at**
