A lake is an area filled with water, localized in a basin, surrounded by land, apart from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, therefore are distinct from lagoons, are larger and deeper than ponds, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which are flowing. Most lakes streams. Natural lakes are found in mountainous areas, rift zones, areas with ongoing glaciation. Other lakes are found along the courses of mature rivers. In some parts of the world there are many lakes because of chaotic drainage patterns left over from the last Ice Age. All lakes are temporary over geologic time scales, as they will fill in with sediments or spill out of the basin containing them. Many lakes are artificial and are constructed for industrial or agricultural use, for hydro-electric power generation or domestic water supply, or for aesthetic, recreational purposes, or other activities.
The word lake comes from Middle English lake, from Old English lacu, from Proto-Germanic *lakō, from the Proto-Indo-European root *leǵ-. Cognates include Dutch laak, Middle Low German lāke as in: de:Wolfslake, de:Butterlake, German Lache, Icelandic lækur. Related are the English words leak and leach. There is considerable uncertainty about defining the difference between lakes and ponds, no current internationally accepted definition of either term across scientific disciplines or political boundaries exists. For example, limnologists have defined lakes as water bodies which are a larger version of a pond, which can have wave action on the shoreline or where wind-induced turbulence plays a major role in mixing the water column. None of these definitions excludes ponds and all are difficult to measure. For this reason, simple size-based definitions are used to separate ponds and lakes. Definitions for lake range in minimum sizes for a body of water from 2 hectares to 8 hectares. Charles Elton, one of the founders of ecology, regarded lakes as waterbodies of 40 hectares or more.
The term lake is used to describe a feature such as Lake Eyre, a dry basin most of the time but may become filled under seasonal conditions of heavy rainfall. In common usage, many lakes bear names ending with the word pond, a lesser number of names ending with lake are in quasi-technical fact, ponds. One textbook illustrates this point with the following: "In Newfoundland, for example every lake is called a pond, whereas in Wisconsin every pond is called a lake."One hydrology book proposes to define the term "lake" as a body of water with the following five characteristics: it or fills one or several basins connected by straits has the same water level in all parts it does not have regular intrusion of seawater a considerable portion of the sediment suspended in the water is captured by the basins the area measured at the mean water level exceeds an arbitrarily chosen threshold With the exception of the seawater intrusion criterion, the others have been accepted or elaborated upon by other hydrology publications.
The majority of lakes on Earth are freshwater, most lie in the Northern Hemisphere at higher latitudes. Canada, with a deranged drainage system has an estimated 31,752 lakes larger than 3 square kilometres and an unknown total number of lakes, but is estimated to be at least 2 million. Finland has larger, of which 56,000 are large. Most lakes have at least one natural outflow in the form of a river or stream, which maintain a lake's average level by allowing the drainage of excess water; some lakes do not have a natural outflow and lose water by evaporation or underground seepage or both. They are termed endorheic lakes. Many lakes are artificial and are constructed for hydro-electric power generation, aesthetic purposes, recreational purposes, industrial use, agricultural use or domestic water supply. Evidence of extraterrestrial lakes exists. Globally, lakes are outnumbered by ponds: of an estimated 304 million standing water bodies worldwide, 91% are 1 hectare or less in area. Small lakes are much more numerous than large lakes: in terms of area, one-third of the world's standing water is represented by lakes and ponds of 10 hectares or less.
However, large lakes account for much of the area of standing water with 122 large lakes of 1,000 square kilometres or more representing about 29% of the total global area of standing inland water. Hutchinson in 1957 published a monograph, regarded as a landmark discussion and classification of all major lake types, their origin, morphometric characteristics, distribution; as summarized and discussed by these researchers, Hutchinson presented in it a comprehensive analysis of the origin of lakes and proposed what is a accepted classification of lakes according to their origin.

Little Kanawha River
The Little Kanawha River is a tributary of the Ohio River, 169 mi long, in western West Virginia in the United States. Via the Ohio, it is part of the watershed of the Mississippi River, draining an area of 2,320 mi² on the unglaciated portion of the Allegheny Plateau, it served as an important commercial water route in the early history of West Virginia in the logging and petroleum industries. The Little Kanawha rises in southern Upshur County 20 mi south of Buckhannon, it follows a meandering course west-northwestwardly, through Lewis, Gilmer, Calhoun and Wood Counties, past the communities of Burnsville, Stouts Mills, Sand Fork, Grantsville, Creston, Burning Springs, Palestine and Newark, to its mouth at the Ohio River in Parkersburg. About 3 mi upstream of Burnsville, a U. S. Army Corps of Engineers dam causes the river to form Burnsville Lake, completed in 1976 at a cost of $56.2 million. Along its course the Little Kanawha River collects the Right Fork Little Kanawha River on the boundary of Lewis and Braxton counties.
Additionally, a minor tributary near Grantsville is known as the Bull River. The Little Kanawha River was named for its smaller size relative to the nearby Kanawha River.

In hydrology, the inflow of a body of water is the source of the water in the body of water. It can refer to the average volume of incoming water in unit time, it is contrasted with outflow. All bodies of water have multiple inflows, but one inflow may predominate and be the largest source of water. However, in many cases, no single inflow will predominate and there will be multiple primary inflows. For a lake, the inflow may be a river or stream that flows into the lake. Inflow may be speaking, not flows, but rather precipitation, like rain. Inflow can be used to refer to groundwater recharge; the dictionary definition of inflow at Wiktionary
A gatehouse, gate house, outlet works or valve house for a dam is a structure housing sluice gates, valves, or pumps. Many gatehouses are utilitarian, but in the nineteenth century, some were elaborate. A set of outlet works is a device used to regulate water flow from a dam; such devices consist of one or more pipes or tunnels through the embankment of the dam, directing water under high pressure to the river downstream. These structures are used when river flow exceeds the capacity of the power plant or diversion capacity of the dam, but do not have flows high enough to warrant the use of the dam spillways, they may be utilized when river flows must be bypassed due to maintenance work in the power station or diversion gates. Although similar in purpose to spillways, outlet works provide a more controlled release to meet downstream flow requirements. A typical set of outlet works begins in an intake structure, a canal or intake tower. A regulating gate or valve controls water flow into the pipes of the outlet works, which discharge downstream into a stilling basin or directly into the river.
The inlets of the outlet works may consist of either gates or valves, or be composed of a more primitive system of stoplogs. Inlets may contain a series of other devices for different purposes, including trash racks and fish screens. Category:Gatehouses – listing notable examples
West Virginia is a state located in the Appalachian region in the Southern United States, considered to be a part of the Middle Atlantic States. It is bordered by Pennsylvania to the north, Maryland to the east and northeast, Virginia to the southeast, Kentucky to the southwest, Ohio to the northwest. West Virginia is the 41st largest state by area, is ranked 38th in population; the capital and largest city is Charleston. West Virginia became a state following the Wheeling Conventions of 1861, after the American Civil War had begun. Delegates from some Unionist counties of northwestern Virginia decided to break away from Virginia, although they included many secessionist counties in the new state. West Virginia was admitted to the Union on June 20, 1863, was a key border state during the war. West Virginia was the only state to form by separating from a Confederate state, the first to separate from any state since Maine separated from Massachusetts, was one of two states admitted to the Union during the American Civil War.
While a portion of its residents held slaves, most of the residents were yeomen farmers, the delegates provided for gradual abolition of slavery in the new state Constitution. The Census Bureau and the Association of American Geographers classify West Virginia as part of the Southern United States; however the Bureau of Labor Statistics classifies West Virginia as a part of the Mid-Atlantic. The northern panhandle extends adjacent to Pennsylvania and Ohio, with the West Virginia cities of Wheeling and Weirton just across the border from the Pittsburgh metropolitan area, while Bluefield is less than 70 miles from North Carolina. Huntington in the southwest is close to the states of Ohio and Kentucky, while Martinsburg and Harpers Ferry in the Eastern Panhandle region are considered part of the Washington metropolitan area, in between the states of Maryland and Virginia; the unique position of West Virginia means that it is included in several geographical regions, including the Mid-Atlantic, the Upland South, the Southeastern United States.
It is the only state, within the area served by the Appalachian Regional Commission. The state is noted for its mountains and rolling hills, its significant logging and coal mining industries, its political and labor history, it is known for a wide range of outdoor recreational opportunities, including skiing, whitewater rafting, hiking, mountain biking, rock climbing, hunting. Many ancient man-made earthen mounds from various prehistoric mound builder cultures survive in the areas of present-day Moundsville, South Charleston, Romney; the artifacts uncovered in these give evidence of village societies. They had a tribal trade system culture. In the 1670s during the Beaver Wars, the powerful Iroquois, five allied nations based in present-day New York and Pennsylvania, drove out other American Indian tribes from the region in order to reserve the upper Ohio Valley as a hunting ground. Siouan language tribes, such as the Moneton, had been recorded in the area. A century the area now identified as West Virginia was contested territory among Anglo-Americans as well, with the colonies of Pennsylvania and Virginia claiming territorial rights under their colonial charters to this area before the American Revolutionary War.
Some speculative land companies, such as the Vandalia Company, the Ohio Company and Indiana Company, tried to legitimize their claims to land in parts of West Virginia and present day Kentucky, but failed. This rivalry resulted in some settlers petitioning the Continental Congress to create a new territory called Westsylvania. With the federal settlement of the Pennsylvania and Virginia border dispute, creating Kentucky County, Kentuckians "were satisfied, the inhabitants of a large part of West Virginia were grateful."The Crown considered the area of West Virginia to be part of the British Virginia Colony from 1607 to 1776. The United States considered this area to be the western part of the state of Virginia from 1776 to 1863, before the formation of West Virginia, its residents were discontented for years with their position in Virginia, as the government was dominated by the planter elite of the Tidewater and Piedmont areas. The legislature had electoral malapportionment, based on the counting of slaves toward regional populations, the western white residents were underrepresented in the state legislature.
More subsistence and yeoman farmers lived in the west and they were less supportive of slavery, although many counties were divided on their support. The residents of this area became more divided after the planter elite of eastern Virginia voted to secede from the Union during the Civil War. Residents of the western and northern counties set up a separate government under Francis Pierpont in 1861, which they called the Restored Government. Most voted to separate from Virginia, the new state was admitted to the Union in 1863. In 1864 a state constitutional convention drafted a constitution, ratified by the legislature without putting it to popular vote. West Virginia abolished slavery by a gradual process and temporarily disenfranchised men who had held Confederate office or fought for the Confederacy. West Virginia's history has been profoundly affected by its mountainous terrain and vast river valleys, rich natural resources; these were all factors driving its economy and the lifestyles of its residents, who tended to live in many small isolated communities in the mountain valleys.
A 2010 analysis of
United States Congress
The United States Congress is the bicameral legislature of the Federal Government of the United States. The legislature consists of two chambers: the House of the Senate; the Congress meets in the United States Capitol in Washington, D. C.. Both senators and representatives are chosen through direct election, though vacancies in the Senate may be filled by a gubernatorial appointment. Congress has 535 voting members: 100 senators; the House of Representatives has six non-voting members representing Puerto Rico, American Samoa, the Northern Mariana Islands, the U. S. Virgin Islands, the District of Columbia in addition to its 435 voting members. Although they cannot vote in the full house, these members can address the house and vote in congressional committees, introduce legislation; the members of the House of Representatives serve two-year terms representing the people of a single constituency, known as a "district". Congressional districts are apportioned to states by population using the United States Census results, provided that each state has at least one congressional representative.
Each state, regardless of population or size, has two senators. There are 100 senators representing the 50 states; each senator is elected at-large in their state for a six-year term, with terms staggered, so every two years one-third of the Senate is up for election. To be eligible for election, a candidate must be aged at least 25 or 30, have been a citizen of the United States for seven or nine years, be an inhabitant of the state which they represent; the Congress was created by the Constitution of the United States and first met in 1789, replacing in its legislative function the Congress of the Confederation. Although not mandated, in practice since the 19th century, Congress members are affiliated with the Republican Party or with the Democratic Party and only with a third party or independents. Article One of the United States Constitution states, "All legislative Powers herein granted shall be vested in a Congress of the United States, which shall consist of a Senate and House of Representatives."
The House and Senate are equal partners in the legislative process—legislation cannot be enacted without the consent of both chambers. However, the Constitution grants each chamber some unique powers; the Senate ratifies treaties and approves presidential appointments while the House initiates revenue-raising bills. The House initiates impeachment cases. A two-thirds vote of the Senate is required before an impeached person can be forcibly removed from office; the term Congress can refer to a particular meeting of the legislature. A Congress covers two years; the Congress ends on the third day of January of every odd-numbered year. Members of the Senate are referred to as senators. Scholar and representative Lee H. Hamilton asserted that the "historic mission of Congress has been to maintain freedom" and insisted it was a "driving force in American government" and a "remarkably resilient institution". Congress is the "heart and soul of our democracy", according to this view though legislators achieve the prestige or name recognition of presidents or Supreme Court justices.
One analyst argues that it is not a reactive institution but has played an active role in shaping government policy and is extraordinarily sensitive to public pressure. Several academics described Congress: Congress reflects us in all our strengths and all our weaknesses, it reflects our regional idiosyncrasies, our ethnic and racial diversity, our multitude of professions, our shadings of opinion on everything from the value of war to the war over values. Congress is the government's most representative body... Congress is charged with reconciling our many points of view on the great public policy issues of the day. Congress is changing and is in flux. In recent times, the American south and west have gained House seats according to demographic changes recorded by the census and includes more minorities and women although both groups are still underrepresented. While power balances among the different parts of government continue to change, the internal structure of Congress is important to understand along with its interactions with so-called intermediary institutions such as political parties, civic associations, interest groups, the mass media.
The Congress of the United States serves two distinct purposes that overlap: local representation to the federal government of a congressional district by representatives and a state's at-large representation to the federal government by senators. Most incumbents seek re-election, their historical likelihood of winning subsequent elections exceeds 90 percent; the historical records of the House of Representatives and the Senate are maintained by the Center for Legislative Archives, a part of the National Archives and Records Administration. Congress is directly responsible for the governing of the District of Columbia, the current seat of the federal government; the First Continental Congress was a gathering of representatives from twelve of the thirteen British Colonies in North America. On July 4, 1776, the Second Continental Congress adopted the Declaration of Independence, referring to the new nation as the "United States of America"; the Articles of Confederation in 1781 created the Congress of the Confederation, a
