Join Our Friends
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.
The Alice Ferguson Foundation was established in 1954 as a non-profit organization chartered in the state of Maryland. Our mission is to provide experiences that encourage connections between people, the natural environment, farming and the cultural heritage of the Potomac River Watershed, which lead to personal environmental responsibility.
The Potomac Appalachian Trail Club is a volunteer-based organization, headquartered in Vienna, Virginia. The PATC was founded in 1927 by the visionaries who planned and built the Appalachian Trail. The club now manages more than 1,200 miles of hiking trails in the Mid-Atlantic region, along with cabins, shelters, and hundreds of acres of conserved land. The PATC conducts trail workshops in Rock Creek Park and helps to maintain our trail system.
Friends of Georgetown Waterfront Park
The Friends of Georgetown Waterfront Park (FOGWP) is a nonprofit organization with over 200 members working to raise awareness of the park and support its construction through friend-raising and fundraising. Individuals with an interest in supporting the park are encouraged to contact FOGWP.
