The Anacostia River // 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. 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.
The mainstem of the Anacostia is formed by the confluence of the Northwest Branch and the Northeast Branch just north of Cottage City, 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.
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.
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.

One of the biggest problems facing the Anacostia River is raw sewage that enters the river and its tributaries. During rainstorms, the river receives discharges of untreated sewage due to the city's antiquated combined sewer system. 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.
According to Rianna Murray et al, many citizens living along the Anacostia River have been exposed to water pollution.[non-primary source needed] One study done on recreational exposure to pollution along the river showed that many people reported "exposure to water while canoeing, kayaking, rowing, rafting, and paddling, and members of this group also reported getting water in their mouth while recreating." This exposure to polluted water has potential adverse effects on the health of individuals and their community.
The Anacostia Watershed Society (AWS) sued the District of Columbia Water and Sewer Authority (DCWASA) 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.
In late 2004, AWS and other organizations announced plans to sue the Washington Suburban Sanitary Commission (WSSC), the sewage authority in Maryland, 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.
Mitigation of sewage overflowsEdit
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. The governments of Montgomery County and Prince George's County also operate stormwater management programs in their respective jurisdictions.
In response to the litigation, in 2011 DCWASA began construction of a large system of sewage storage tunnels to address the combined sewer overflow problem in the Anacostia River. Four deep storage tunnels adjacent to the Anacostia and Potomac Rivers will reduce overflows to the Anacostia by 98 percent, and 96 percent system-wide. When completed the system will comprise over 18 miles of tunnels with a storage capacity of 157 million gallons. The first segment of the tunnel system, 7 miles in length, went online in 2018. The remaining segments of the storage system are scheduled for completion in 2023. (The city's overall "Clean Rivers" project, projected to cost $2.6 billion, includes other components, such as reducing stormwater flows.)
In May 2009, a Bandalong Litter Trap floating litter-control system was placed in the Watts Branch tributary of the Anacostia River as part of Mayor Adrian Fenty's "Green DC Agenda." In its first year of operation, it removed more than 500 pounds (230 kg) of floatable litter per month from the river.
The Bladensburg Waterfront Park, part of the Prince George's County Department of Parks and Recreation, currently occupies the banks of the Anacostia near Alternate Route 1. 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.
The Anacostia Riverwalk Trail (partially complete as of June 2016) connects Bladensburg Waterfront Park the Tidal Basin via 28 miles (45 km) of paved, shared-use path with connections and spurs to the National Arboretum, Kenilworth Aquatic Gardens, Nationals Park, Maine Avenue Fish Market, and other locations.
