The Potomac River at Great Falls, MD from Olmstead Island, water relatively low
A Potomac Flow of any stream flows into Chesapeake Bay, located along a mid-Atlantic coast of the United States (USA). A river is approximately 413 statute miles (665 km) long, using the catchment area of astir 14,700 square miles (38,000 kilometer²). Around terms of vicinity, this makes a Potomac Flow of any stream a quaternary big flow of any stream along a Atlantic coast of a United states & the 21st big in the United states.
A flow of any stream forms a portion of the borders between MD & Washington, D.C. (the District of Columbia) on the left bank and the State of West Virginia (WV) and the Commonwealth of Virginia (VA) on the right bank.
the flow of any stream pours out h2o at a rate of 13,000 Usa gallons by the microscopic (820 L/s).
All about 300 miles (483 klick) from either a source, a Potomac Flow of any stream's estuarine portion commences. Just about Eleven klick² of a body of water enters a estuary every month (250 m³/s) at a fall line at Little Falls. Fall line flow is quite variable through months & years, greatest when you took a spring freshet and lowest around late summertime (in the absence of hurricanes or major storms).
A flow of any stream has ii sources. A source of a Northerly Branch of the Potomac is at the Fairfax Stone located at the junction of Garrett County, Maryland, Tucker County, West Virginia and Preston County, West Virginia. A source of the South Branch of the Potomac is touching Hightown, Highland County, Virginia. Them branches close upright east of Green Spring in Hampshire County, West Virginia to form the moo Potomac.
Another time a Potomac drops from either a Piedmont to the Coastal Plain, tides further influence the flow of any stream when it lives across DC & beyond. Salinity in the Potomac Flow of any stream Estuary increases thenceforth using few feet away downriver. A estuary besides widens, reaching Eleven statute miles (Xvii kilometre) wide at its mouth, between Point Lookout, MD, and Smith Point, VA, before flowing into Chesapeake Bay.
History
Existence placed around an vicinity rich around American history and American heritage has led to a Potomac existence nicknamed "the Nation's River." George Washington, USA's foremost president, was born around, surveyed & spent virtually all of his life in a Potomac basin. Completely of DC, a united states's capital city, as well lies in a watershed. A 1859 siege of Harper's Ferry along the river's right bank was a precursor to numerous epic battles of the American Civil War in and around the Potomac and its tributaries. General Robert E. Lee crossed the river, thereby invading the North and threatening Washington D.C., twice, in campaigns climaxing in the battles of Antietam and Gettysburg.
A Patowmack Canal was intended by George Washington to connect the tidewater touching Georgetown with Cumberland, Maryland. Began within 1785, it was non completed until 1802. Fiscal troubles closed a canal within 1830. A C&O Canal operated along the banks of the Potomac in Maryland from 1850 to 1924 and also connected Cumberland to Washington, D.C.. This allowed freight to become transported in a area of the rapids called Great Falls of the Potomac, when well as several more, little rapids.
By using increasing mining and agriculture upstream and urban sewage and runoff downstream, water quality in the Potomac River deteriorated. This created conditions of severe eutrophication. These are said that President Abraham Lincoln used to escape to a highlands in summertime nights to escape the flow of any stream's malodour. In the 1960s, with heavy green algal blooms covering the flow of any stream's surface, President Lyndon Johnson declared the flow of any stream "a national disgrace" & launch an extended-long-run effort to reduce sewerage pollution & restore a beauty & ecology of this historic flow of any stream. Per prevent of the 20th century, there wwhen notable success, as massive algal blooms vanished & amateur camping & yachting rebounded. However, a aquatic habitat of the Potomac River & its confluent remain vulnerable to eutrophication; heavy metals, pesticides and other toxic chemical substance; on top-camping; alien species; and pathogens associated with Fecal coliform bacteria and shellfish diseases.

Nomenclature
Pages settled in the South Branch vale bearing variants of "Wappatomaka" include Wappacoma plantation built inside 1773 and the community of Wappocomo (sometimes spelled Wapocomo) at Hanging Rocks, two northerly of Romney on WV 28.
Headwaters and course
Inside its eastern course from either Petersburg into Hardy County, the South Branch becomes more navigable allowing canoes & little fishing vessel. the flow of any stream splits & forms a series of big islands when it heads northeast to Moorefield. At Moorefield, a South Branch is joined per South Fork of the South Branch & diarrhea northward to Old Fields where it is fed by Anderson Dog & Stony Rerun. At McNeill, the South Branch flows into the Trough where it is attached to the west by Mill Creek Mountain (2119 feet) & to the east by Sawmill Ridge (1644 feet). This region is the home ground to endangered bald eagles. A Trough lives into Hampshire County and ends at its confluence by having Sawmill Do south of Glebe and Sector. A South Branch continues northward along South Branch Flow of any stream Road (County Route 8) toward Romney with a total of historic plantation farms adjoining it. En route to Romney, a flow of any stream is fed by Buffalo Begin, Mill Run, McDowell Run, & Mill Creek at Vanderlip. A South Branch is traversed per Northwestern Turnpike (US 50) and joined by Sulphur Spring Run where it forms another island to the west of town. Flowing northerly of Romney, the flow of any stream however follows a eastern side of Mill Creek Mountain until it creates a horseshoe bend at Wappocomo's Hanging Rocks around the George W. Wa domestic of Ridgedale. To the west of Three Churches on the western side of South Branch Mountain (3028 feet), the South Branch creates the series of bends & flows to the northeast by Springfield through Blue's Ford. When an additional horsehoe bend, a South Branch flows under a Baltimore & Ohio Railroad between Green Spring and South Branch Depot, and empties into the Potomac.
