Anacostia River flows from the Maryland suburbs of Washington, DC
to its mouth at the Potomac River near downtown Washington. Its
watershed encompasses 176 square miles and contains 13 subwatersheds
in southeast Washington, DC and Montgomery and Prince George's Counties
watershed is composed of three main drainage areas - the Northeast
Branch, the Northwest Branch, and the tidal river. The Northeast
and Northwest Branches converge in Bladensburg, MD and form the
tidal Anacostia River, which flows 8.4 miles through Maryland and
Washington, DC until it meets the Potomac River at Hain's Point.
Anacostia Watershed is home to over 800,000 residents of Maryland
and Washington, DC and includes some of the most economically distressed
areas in the metropolitan region.
loss, deforestation, and urbanization have significantly degraded
the water quality of the Anacostia River. About 23 percent of the
land area of the watershed is impervious. Urbanization is particularly
dense on the east and west banks of the tidal river in Washington,
DC, where more than 70 percent of the land is covered by impervious
1987, the District of Columbia, the State of Maryland, and the Counties
of Montgomery and Prince George's jointly signed the Anacostia Watershed
Restoration Agreement. This agreement officially recognized the
ecological and economic importance of the river and resulted in
the formation of the Anacostia Watershed Restoration Committee (AWRC).
The primary goal of the AWRC is to plan and coordinate restoration
projects throughout the watershed.
AWRC commissioned a comprehensive inventory of the watershed to
identify necessary restoration projects. By 1990, the AWRC had identified
207 stormwater retrofit, stream restoration, wetland creation, and
riparian reforestation projects.
1998, the AWRC reported that more than 700 restoration projects
had been planned and that 30 percent of them had been completed
since the organization's founding.
