Anacostia River Watershed

The Anacostia River /ænəˈkɒstiə/ is a river in the Mid Atlantic region of the United States. It flows from Prince George's County in Maryland into Washington, D.C., where it joins with the Washington Channel to empty into the Potomac River at Buzzard Point. It is approximately 8.7 miles (14.0 km) long.^[1] The name "Anacostia" derives from the area's early history as Nacotchtank, a settlement of Necostan or Anacostan Native Americans on the banks of the Anacostia 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.

Course

The mainstem of the Anacostia is formed by the confluence of the Northwest Branch and the Northeast Branch just north of Bladensburg, Maryland. Tributaries of these sources include Sligo Creek, Paint Branch, Little Paint Branch, Indian Creek; Upper Beaverdam Creek, Dueling Branch, and Brier's Mill Run. Tributaries of the mainstem Anacostia include Watts Branch, Lower Beaverdam Creek and Hickory Run.

Watershed

The watershed of the river roughly covers 176 sq mi (460 km²) in eastern Montgomery County and northern Prince George's County, as well as parts of Washington, D.C.

History

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. On earlier maps, the river was known as the "Eastern Branch of the Potomac River" until it received its current, official name.

The Washington City Canal operated from 1815 until the mid-1850s, initially connecting the Anacostia to Tiber Creek and the Potomac River; and later to the Chesapeake and Ohio Canal. The city canal fell into disuse in the late 19th century, and the city government covered over or filled in various sections.^[2]

During the American Civil War, an extensive line of forts was constructed south of the river in order to prevent Confederate artillery from bombarding the Washington Navy Yard, which lies adjacent to the river.

Pollution sources

One of the biggest problems facing the Anacostia River is raw sewage that enters the river and its tributaries because of antiquated sewer systems. The sewage creates a public health threat because of 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 2,000,000,000 US gallons (7,600,000 m³) of combined sewage and urban runoff (stormwater) to flow into the river via its antiquated combined sewer overflow system. In settling the lawsuit, WASA agreed to invest $140 million on pump station rehabilitation, pipe cleaning and maintenance and public notices of overflows.

Pursuant to a stormwater discharge permit issued by the U.S. Environmental Protection Agency (EPA), the D.C. government is implementing a stormwater management program to improve water quality in the Anacostia.^[3] The governments of Montgomery County and Prince George's County also operate stormwater management programs in their respective jurisdictions.^[4][5]

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 4,000,000 US gallons (15,000 m³) of raw sewage were released into Anacostia tributaries between January 2001 and June 2004.

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.^[6]

In May 2009, an innovative device called the Bandalong Litter Trap was placed in the Watts Branch tributary of the Anacostia River. The trap was unveiled by Mayor Adrian Fenty as part of his "Green DC Agenda."^[7] In six months, it removed over 5,000 pounds (2,300 kg) of floatable litter from the river.

Recreational amenities

The Bladensburg Waterfront Park, part of the Prince George's County Department of Parks and Recreation, currently occupies the banks of the Anacostia near Route 1.^[8] The Port Towns Community Boathouse at the park is home to the rowing crews of the University of Maryland, The Catholic University of America, and several local high schools.^[9]
