Watts Branch (Anacostia River)
|Location||Prince George's County, Maryland and Washington, DC, USA|
|Length||4.9 miles (7.9 km)|
|Basin area||11,500 acres (47 km2)|
Watts Branch is a tributary stream of the Anacostia River in Prince George's County, Maryland, and Washington, D.C. The headwaters of the stream originate in the Capitol Heights area of Prince George's County, and the branch flows roughly northwest for 4.9 miles (7.9 km) to the Anacostia, which drains to the Potomac River and the Chesapeake Bay. The watershed area of Watts Branch is about 6,000 acres (24 km2) in Prince George's County and 5,500 acres (22 km2) in Washington.
Watts Branch is in a highly urbanized area, and its water quality has been rated as poor by government agencies. The stream has suffered from urban runoff (stormwater) pollution, including trash dumped by residents and businesses and leaking sewer pipes. Much of the stream is in concrete channels or culverts. A variety of stream cleanup and restoration projects have been initiated by D.C. government, the United States Environmental Protection Agency (EPA) and other federal agencies, in cooperation with community organizations such as the Anacostia Watershed Society and the Watts Branch Community Alliance.
