Our River

The Anacostia River is an 8.5-mile long tidal river that runs through the District of Columbia. The Anacostia watershed is 176 square miles and includes parts of the District, Montgomery County, MD, and Prince George’s County, MD. Nearly one million people live in this watershed, either directly on the Anacostia River or on one of the many streams that connect to it. Our mission is to protect and restore the Anacostia River for all who live, work, and play in the watershed.
