A walk along this boardwalk will take you over one of the greatest environmental restoration efforts in Washington, D.C.
Starting in 1900, dredging, filling and other alterations to the Anacostia river, destroyed this marsh habitat. As a result, many of the plants that previously absorbed and prevented erosion could not survive.
For years local residents urged the city and the federal government to improve the quality of water in the Anacostia River. As a result, the Metropolitan Washington Council of Governments launched the Kenilworth Marsh Project.
During the 1900s, over 32 acres of tidal wetland were restored and native vegetation was reintroduced to provide habitat for native wildlife.

Marsh Waters
The waters of Kenilworth Marsh are tidal, with an average range between tides of 2-3 feet.
Anacostia River water from this marsh flows into the formal ponds of the aquatic gardens.
This boardwalk takes you lover three different marsh zones (low, mid and high) that support unique wildlife habitat.
