About Exploration Green

In Southeast Houston, dedicated groups of volunteers are transforming a defunct golf course into an innovative stormwater detention center and green space.


Exploration Green provides an integrated, natural solution for catastrophic seasonal flooding holding up to 500-million-gallons of stormwater while also serving as a nature preserve and recreation area. Located near NASA's Johnson Space Center, this 200-acre urban green space provides the community with countless opportunities to explore, offering 40 acres of both wetlands and permanent detention lakes, home to over 1,000 native species.

The Clear Lake City Water Authority (CLCWA) manages the construction (excavation) phase of the Exploration Green stormwater detention lakes.  Please visit the Clear Lake City Water Authority's Exploration Green Detention Facility web page for announcements and the the most current updates on construction activities and progress.

Exploration Green Remains Open, Please Exercise Caution due to COVID-19 (Coronavirus)
