Anacostia River watershed
The 'Anacostia River' is a
river that flows about 8.4
mi (13.5
km) from
Prince George's County in
Maryland,
USA and through
Washington, D.C. where it joins with the
Washington Channel to empty into the
Potomac River at
Hains Point. The name "Anacostia" derives from the area's early history as Nacochtank, a settlement of Necostan or Anacostan
Native Americans on the banks of the Anacostia River.
Captain John Smith recorded in his journals that he sailed up the "Eastern Branch" or Anacostia River in 1608 in his search for the main branch of the Potomac River and was well received by the Anacostans.
During the
American Civil War, an extensive line of
forts were constructed south of the river in order to prevent
Confederate artillery from bombarding the
Washington Navy Yard, which lies adjacent to the river.
Heavy
pollution in the Anacostia and weak investment and development along its banks have led to it becoming what many have called "D.C.'s forgotten river." In recent years, however, private organizations, local businesses, and the D.C., Maryland and federal governments have made joint efforts to reduce its pollution levels in order to protect the ecologically valuable Anacostia
watershed.
The watershed of the river roughly covers 176
sq. mi. (456
km²) in eastern
Montgomery County and northern Prince George's County, as well as parts of Washington, D.C.
Tributaries of the Anacostia include Northwest Branch and Northeast Branch, the
confluence of which just above
Bladensburg forms the main stem of the river;
Sligo Creek, Paint Branch, Little Paint Branch, Indian Creek; Beaverdam Creek, Dueling Branch, and Brier Ditch flow into these two tributaries while Lower Beaverdam Creek and Hickory Run flow directly into the river.
Pollution sources
One of the biggest problems facing the Anacostia River is raw
sewage that enters the river and its tributaries due to antiquated
sewer systems. The sewage creates a public health threat due to
fecal coliform bacteria and other pathogens; it also impairs water quality and can create
hypoxic conditions that lead to large fish kills.
The Anacostia Watershed Society (AWS) sued the
Washington, D.C. Water and Sewer Authority (WASA) in
1999 for allowing more than 2 billion US
gallons (7,600,000 m³) of combined sewage and storm water to flow into the river via its antiquated combined sewer overflow system. In settling the lawsuit, WASA agreed to invest
US$140 million on pump station rehabilitation, pipe cleaning and maintenance and public notices of overflows.
In late
2004, AWS and other organizations announced plans to sue the
Washington Suburban Sanitary Commission (WSSC) over similar problems with river contamination from the Maryland suburbs. According to WSSC, more than 4 million US gallons (15,000 m³) of raw sewage were released into Anacostia tributaries between January
2001 and June 2004. The discharges are due to breaks in older sewer lines as well as overwhelmed or failing pumps and clogged lines.
Another large source of river pollution is the
Washington Navy Yard, which is sited alongside the river and is believed to be a source of
PCB contaminants in the river and sediment.
