Geography

The river forms part of the borders between Maryland and Washington, D.C. (the District of Columbia) on the left bank and West Virginia and Virginia on the river's right bank. Washington DC ( formally the District of Columbia and commonly referred to as Washington, the District, or simply D West Virginia ( is a state in the Appalachian Upland South, and Mid-Atlantic regions of the United States, bordered by The Commonwealth of Virginia ( is an American state The entire lower Potomac River is part of the State of Maryland, with the exception of a small tidal portion within the District of Columbia. Except for a small portion of its headwaters in West Virginia, the North Branch Potomac River is considered part of Maryland to the low water mark on the opposite bank. The Potomac River flows into the Chesapeake Bay, located along the mid- Atlantic coast of the United States. The South Branch Potomac River lies completely within the state of West Virginia except for its headwaters, which lie in Virginia. The Potomac River flows into the Chesapeake Bay, located along the mid- Atlantic coast of the United States.

The Potomac River runs 383 miles (616 km) from the Fairfax Stone in West Virginia to Point Lookout, Maryland and drains 14,679 square miles (38,018 km²).

History

"Potomac" is a European spelling of an Algonquian name for a tribe subject to the Powhatan confederacy, that inhabited the upper reaches of the Northern Neck in the vicinity of Fredericksburg. The Algonquian (also Algonkian, and pronounced both and) languages are a subfamily of Native American languages that includes most of the languages in the Algic The Powhatan (also spelled Powatan and Powhaten) or Powhatan Renape (literally the "Powhatan Human Beings" is the name of a The Northern Neck is the northernmost of three Peninsulas on the western shore of the Chesapeake Bay Some accounts say the name means "place where people trade" or "the place to which tribute is brought". ^[2] The natives called the river above the falls Cohongarooton,^[3] translated as "river of geese",^[4] and that area was renowned in early years for an abundance of both geese and swans. The spelling of the name has been simplified over the years from "Patawomeke" (as on Captain John Smith's map) to "Patowmack" in the 18th century and now "Potomac". Captain Sir John Smith (c January 1580– June 21 1631) Admiral of New England was an English Soldier, Sailor Some scholars have also suggested its a rooted in the ancient Greek for river, "potamos", blended with the Powhatan name "Patawomeke".

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, the watermen of Virginia's Northern Neck.

Being situated in an area rich in American history and American heritage has led to the Potomac being nicknamed "the Nation's River. " George Washington, the first President of the United States, was born in, surveyed, and spent most of his life within the Potomac basin. George Washington (February 22 1732 December 14 1799 served as the first President of the United States of America (1789&ndash1797 and led the The President of the United States is the Head of state and Head of government of the United States and is the highest political official in United States by All of Washington, D.

Political dividing point

Some commentators have suggested that, as the Mason-Dixon line demarcated the Northern United States from the Southern United States during the 19th century, so the Potomac River has come to separate the Blue states from the Red States in the 21st century United States. The Mason–Dixon Line (or "Mason and Dixon's Line" is a Demarcation line between four U The Northern United States is a large geographic region of the United States of America. The Southern United States &mdashcommonly referred to as the American South, Dixie, or simply the South &mdashconstitutes a large distinctive See also Electoral geography of the United States Red States and Blue States refer to those states of the United States of America ^[6][7] Since 2000, the river has symbolized a political border between Democratic Maryland and Republican Virginia.

Despite its claimed status as a political buffer between the Blue and the Red, the Potomac has not gained the same kind of notoriety or fame as the Mason-Dixon line as a cultural feature.

Legal issues

For 400 years Maryland and Virginia have disputed control of 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. A constitution is a system for government often Codified as a written document that establishes the rules and principles of an autonomous political entity Both states acceded to the Compact of 1785 and the 1877 Black-Jenkins Award which grants Maryland the river bank-to-bank from the low water mark on the Virginia side, while permitting Virginia full riparian rights short of obstructing navigation.

From 1957 to 1996, the Maryland Department of the Environment (MDE) routinely issued permits applied for by Virginia entities concerning use of the Potomac, however, in 1996 the MDE denied a permit applied for by the Fairfax County Water Authority to build a water intake valve 725 feet (220 m) offshore, citing potential harm to Maryland's interests by an increase in Virginia sprawl caused by the project. Fairfax County is a county in Northern Virginia, in the United States. After years of failed appeals within the Maryland government's appeal processes, in 2000 Virginia took the case to the Supreme Court of the United States, which exercises original jurisdiction in cases between two states. The Supreme Court of the United States is the highest judicial body in the United States and leads the federal judiciary. Maryland claimed Virginia lost its riparian rights by acquiescing to MDE's permit process for 63 years (MDE began its permit process in 1933). A Special Master appointed by the Supreme Court to investigate recommended the case be settled in favor of Virginia, citing the language in the 1785 Compact and the 1877 Award. On December 9, 2003, the Court agreed in a 7-2 decision.

Virginia v. Maryland, 124 S.Ct. 598.

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, the question of West Virginia's succession in title to the lands between the branches of the river was raised, as well as title to the river itself. Claims by Maryland to West Virginia land north of the South Branch (all of Mineral and Grant Counties and parts of Hampshire, Hardy, Tucker and Pendleton Counties) and by West Virginia to the Potomac's high water mark were rejected by the Supreme Court in two separate decisions in 1910. Mineral County is a County located in the US state of West Virginia. Grant County is a County located in the US state of West Virginia.

Conservation

As a result of the damaging floods of 1936 and 1937, the Army Corps of Engineers proposed a series of dams that were intended to regulate the river and to provide a more reliable water supply. The United States Army Corps of Engineers ( USACE) is a federal agency and a major Army command made up of some 34600 Civilian and 650 Military personnel One dam was to be built at Little Falls, backing its pool up to Great Falls. Just above Great Falls, a much larger dam was proposed whose reservoir would extend to Harpers Ferry. Several other dams were proposed on the Potomac and its tributaries. When detailed studies were issued by the Army Corps of Engineers in the 1950's, they met sustained opposition, led by US Supreme Court Chief Justice William O. Douglas, resulting in the plans' abandonment. The Supreme Court of the United States is the highest judicial body in the United States and leads the federal judiciary. William Orville Douglas ( October 16, 1898 – January 19, 1980) was a United States Supreme Court Associate Justice. ^[10] The only project that did get built was Jennings Randolph Lake on the North Branch.

South Branch nomenclature

Early pioneer sources claim that the indigenous Native Americans of the region referred to the South Branch Potomac River as the Wappatomaka. Native Americans in the United States are the indigenous peoples from the regions of North America now encompassed by the continental United States Other variants of this name throughout the river's history were South Branch of Potowmac River, South Branch of the Potowmac River, South Fork Potomac River, Wapacomo River, Wapocomo River, Wappacoma River, Wappatomaka River, and Wappatomica River.

Places settled in the South Branch valley bearing variants of "Wappatomaka" include Wappacoma plantation built in 1773 and the unincorporated hamlet of Wappocomo (sometimes spelled Wapocomo) at Hanging Rocks, both north of Romney on West Virginia Route 28.
