Gathright Dam
Gathright Dam is an earthen and rolled rock-fill embankment dam on the Jackson River north of Covington, Virginia. The dam is tall and long and has a controlled spillway within the structure's southern portion. It creates Lake Moomaw, which has a normal volume of . The dam serves flood control and recreational purposes and is operated by the U.S. Army Corps of Engineers. The Gathright Dam's intake tower contains nine portals that allow it to release water between reservoir depths of . This allows the dam to manage the temperature and flow of water released downstream. This helps mitigate some of the negative environmental effects posed by the dam and manage fisheries downstream. History and construction The Gathright Dam was authorized by Congress with the Flood Control Act of 1946 to provide flood protection of industrial, commercial and residential properties along the Jackson and James Rivers, with immediate impact on Covington, Virginia.

Jackson River (United States)
The Jackson River is a major tributary of the James River in the U.S. state of Virginia, flowing .U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map , accessed April 1, 2011 The James River is formed by the confluence of the Jackson River and the Cowpasture River. Course The Jackson River rises in Highland County, Virginia, near the border of West Virginia. It flows south between Back Creek Mountain and Jack Mountain, entering Bath County, where it continues to flow south. The Jackson River is impounded by Gathright Dam in Alleghany County, creating Lake Moomaw. From the dam, Jackson River flows south and then east through Alleghany County, through the city of Covington and the town of Clifton Forge, before joining with the Cowpasture River to create the James River. The river is named for the first white settler on its banks, William Jackson, who received a grant of from King George II in 1750. Jackson was possibly an acquain ...

Reservoir
A reservoir (; from French ''réservoir'' ) is an enlarged lake behind a dam. Such a dam may be either artificial, built to store fresh water or it may be a natural formation. Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, through excavation, or building any number of retaining walls or levees. In other contexts, "reservoirs" may refer to storage spaces for various fluids; they may hold liquids or gasses, including hydrocarbons. ''Tank reservoirs'' store these in ground-level, elevated, or buried tanks. Tank reservoirs for water are also called cisterns. Most underground reservoirs are used to store liquids, principally either water or petroleum.

George Washington And Jefferson National Forests
The George Washington and Jefferson National Forests is an administrative entity combining two U.S. National Forests into one of the largest areas of public land in the Eastern United States. The forests cover of land in the Appalachian Mountains of Virginia, West Virginia, and Kentucky. Approximately of the forest are remote and undeveloped and have been designated as wilderness areas, which prohibits future development. History George Washington National Forest was established on May 16, 1918, as the Shenandoah National Forest. The forest was renamed after the first President on June 28, 1932. Natural Bridge National Forest was added on July 22, 1933. Jefferson National Forest was formed on April 21, 1936, by combining portions of the Unaka and George Washington National Forests with other land. In 1995, the George Washington and Jefferson National Forests were administratively combined. The border between the two forests roughly follows the James River. The combine ...

Dams Completed In 1979
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam.

Buildings And Structures In Alleghany County, Virginia
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flood Control Act Of 1946
The Flood Control Act of 1946 was passed by the United States Congress on July 24, 1946; to authorize 123 projects including several dams and hydroelectric power plants like Old Hickory Lock and Dam in Tennessee and the Fort Randall Dam in South Dakota. It also allowed bank adjustments and re-directions for several rivers. The plan authorized the Secretary of War to regulate the surveillance of flood control and other improvements as well as the ability to call for a review of said surveys. The Secretary of Agriculture and the Department of Engineers were also charged with conducting surveys relating to their respective fields. Budget The plan allocated $1,427,097,038 for the projects. The act also allotted a maximum of $1,000,000 annually to be used for removing debris and clearing channels, $2,000,000 to be used for rescue and repair of levees damaged by flooding, and $957,000,000 to be used for other miscellaneous actions.
