About Project Brays

Willow Waterhole Stormwater Detention Basin

Bringing Flood Damage Reduction to Southwest Houston

As one of Project Brays' four large stormwater detention basins, the Willow Waterhole Stormwater Detention Basin is designed to reduce flooding and bring much needed greenspace to area residents and businesses in southwest Houston. The Willow Waterhole Stormwater Detention Basin is located near S. Post Oak Rd. and US Highway 90 in southwest Harris County. The project also includes a link to the Willow Waterhole Bayou between Gasmer and South Willow Drive.

The Willow Waterhole Stormwater Detention Basin is designed to hold water during heavy rainfall to reduce peak flows in the channel that can cause flooding. Upon completion, the basin will hold approximately 600 million gallons of stormwater. In addition, the basin project will offer 279 acres of usable greenspace for the nearby community.

Creating Opportunities for Recreational & Aesthetic Amenities

Project Brays has presented a unique opportunity for other organizations to build upon the federal flood damage reduction initiative and create local initiatives to enhance projects like the Willow Waterhole Stormwater Detention Basin with recreational and aesthetic features.

For instance, the Willow Waterhole Stormwater Detention Basin includes the Willow Waterhole Greenway Project, a local initiative that provides the stormwater detention basin with recreational and aesthetic amenities. When not being used for flood damage reduction purposes, the Willow Waterhole Stormwater Detention Basin is a special place for neighbors and families to gather and enjoy. Through a $750,000 grant from the Texas Parks and Wildlife Department, the City of Houston Parks and Recreation Department was able to fund construction of some recreational and aesthetic amenities during the initial development of the Willow Waterhole Stormwater Detention Basin. The area now includes amenities such as walking paths and bridges, bike trails, playgrounds and picnic areas. It is important to note that the recreational and aesthetic features are not part of the federal project.

A Model Partnership

The Willow Waterhole Greenway Project is a prime example of the partnership between HCFCD, the Corps, the City of Houston Parks and Recreation Department and the Texas Parks and Wildlife Department. This unique partnership sets a new standard, demonstrating how different entities can work together to benefit the communities they serve. This project came to fruition because of the dedication and commitment put forth by a broad base of community leaders and organizations including the Willow Waterhole Greenspace Conservancy, which collectively helped to foster relationships and promote the project.

Project Status

HCFCD began construction on the Willow Waterhole Stormwater Detention Basin in May 2004, and construction is approximately 60 percent complete. Construction continues, and upon completion, almost 1,865 acre-feet of stormwater storage will be available to hold excess stormwater. It is important to remember that every phase completed will deliver some level of relief and steadily reduce the risk of flooding.
