Native Americans had different names for different parts of the river, calling the river above Great Falls Cohongarooton , meaning "honking geese" and "Patawomke" below the Falls, meaning "river of swans". In 1608, Captain John Smith explored the river now known as the Potomac and made drawings of his observations which were later compiled into

To the west of Three Churches on the western side of South Branch Mountain , 3,028 feet (923 m), the South Branch creates a series of bends and flows to the northeast by Springfield through Blue's Ford. After two additional horseshoe bends (meanders), the South Branch flows under the old Baltimore and Ohio Railroad mainline between Green Spring and South Branch Depot , and joins

About 3.70% of families and 5.50% of the population were below the poverty line , including 6.70% of those under age 18 and 8.60% of those age 65 or over. As of 2010,

408-485: A map and published in London in 1612. This detail from that map shows his rendition of the river that the local tribes had told him was called the "Patawomeck". The spelling of the name has taken many forms over the years from " Patawomeck " (as on Captain John Smith 's map) to "Patomake", "Patowmack", and numerous other variations in the 18th century and now "Potomac". The river's name was officially decided upon as "Potomac" by

One of

1088-511: The Board on Geographic Names in 1931. The similarity of the name to the Ancient Greek word for river, potamos , has been noted for more than two centuries but it appears to be due to chance. The Potomac River brings together a variety of cultures throughout the watershed from the coal miners of upstream West Virginia to the urban residents of the nation's capital and, along the lower Potomac,

Beginning in the 19th century, with increasing mining and agriculture upstream and urban sewage and runoff downstream, the water quality of the Potomac River deteriorated. This created conditions of severe eutrophication . It

1632-547: The 1980s, through sewage plant upgrades and restrictions on phosphorus in detergents. By the end of the 20th century, notable success had been achieved, as massive algal blooms vanished and recreational fishing and boating rebounded. Still, the aquatic habitat of the Potomac River and its tributaries remain vulnerable to eutrophication, heavy metals , pesticides and other toxic chemicals, over-fishing, alien species , and pathogens associated with fecal coliform bacteria and shellfish diseases. In 2005 two federal agencies,

This section covers

1836-437: The Potomac and its North Branch since both states' original colonial charters grant the entire river rather than half of it as is normally the case with boundary rivers. In its first state constitution adopted in 1776, Virginia ceded its claim to the entire river but reserved free use of it, an act disputed by Maryland. Both states acceded to the 1785 Mount Vernon Compact and the 1877 Black-Jenkins Award which granted Maryland

1904-556: The Potomac as its principal source of drinking water with the opening of the Washington Aqueduct in 1864, using a water intake constructed at Great Falls.

On December 9, 2003, the Court agreed in a 7–2 decision. The original charters are silent as to which branch from the upper Potomac serves as the boundary, but this was settled by the 1785 Compact. When West Virginia seceded from Virginia in 1863,

2380-512: The Virginia side of the river, it was not completed until 1802. Financial troubles led to the closure of the canal in 1830. The Chesapeake and Ohio Canal operated along the banks of the Potomac in Maryland from 1831 to 1924 and also connected Cumberland to Washington, D.C. This allowed freight to be transported around the rapids known as the Great Falls of the Potomac River , as well as many other, smaller rapids. Washington, D.C. began using

John Tayloe I purchased land around Nanjemoy Creek after 1710 from which to mine iron and ship to his furnaces at Bristol Iron Works , Neabsco Iron Works and later Occoquan Ironworks.

Douglas , resulting in the plans' abandonment. The only dam project that did get built

3264-633: The nation's capital was to be located on the river. The 1859 siege of Harper's Ferry at the river's confluence with the Shenandoah was a precursor to numerous epic battles of the American Civil War in and around the Potomac and its tributaries, such as the 1861 Battle of Ball's Bluff and the 1862 Battle of Shepherdstown .

George Washington , the first President of the United States , was born in, surveyed, and spent most of his life within, the Potomac basin. All of Washington, D.C., the nation's capital city , also lies within the watershed. The First United States Congress by act of July 16, 1790 stated that

This is why the mountain is more ridgelike and less rugged than sections to the south. The greenstone was deposited during the Catoctin Formation and uplifted during the Alleghenian Orogeny . Blue Ridge Mountain contains several national, state, regional and private parks that offer recreational opportunities on
