Halls Bayou, a tributary of Greens Bayou, is located in north-central Harris County. Approximately 20 miles in length, Halls Bayou collects stormwater from the Veterans Memorial Drive area, flowing east until it joins Greens Bayou at the City of Houston’s Brock Park. The watershed includes 37 tributaries that are more than one mile in length.

Historically, the Halls Bayou watershed has been solely designated as a sub-watershed of Greens Bayou. While it is still a sub-watershed of Greens Bayou, in 2021, the Flood Control District moved to officially designate Halls Bayou as its own watershed, making it Harris County’s 23rd watershed.

The watershed comprises approximately 45 square miles, mostly developed with a mix of residential, commercial and industrial uses. The population of the watershed is approximately 160,100, based on the 2010 Census.

Reducing flooding risks in the Halls Bayou watershed is a priority for the Harris County Flood Control District. The Bond Program approved by voters in 2018 includes more than $110 million for the Halls Bayou watershed, which has the potential to leverage more than $346 million in total project value, depending on federal funding approval.
