Rock Creek Conservancy

Rock Creek Conservancy (formerly Friends of Rock Creek's Environment) is a nonprofit group working to protect and restore Rock Creek and its waters, parks, and lands.

Rock Creek Conservancy is the only organization that focuses on Rock Creek in its entirety. The creek meanders 33 miles through the Washington metropolitan area, crossing federal lands as well as district, city, county, and state boundaries. Although parkland borders much of the creek, the surrounding development threatens the health and beauty of these natural areas.
