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.

Toccoa River
The Toccoa River and Ocoee River are the names in use for a single river that flows northwestward through the southern Appalachian Mountains of the southeastern United States. It is a tributary of the Hiwassee River, which it joins in Polk County, Tennessee, near the town of Benton. Three power generating dams are operated along it. The river is called the Toccoa for its through Georgia, until it reaches the twin cities of McCaysville, Georgia and Copperhill, Tennessee, at the truss bridge which connects Georgia 5 ( Blue Ridge Street) with Tennessee 68 and Georgia 60 (Ocoee Street and Toccoa Street). The remainder is called the Ocoee through Tennessee. The Ocoee is globally known for its Class III-V whitewater rapids, appealing to kayakers and rafting enthusiasts. It is also home to the local salamander, ''Desmognathus ocoee''. The upper section of the Ocoee was host to whitewater slalom events during the Centennial 1996 Summer Olympics held primarily in Atlanta, about to ...

Above Mean Sea Level
Height above mean sea level is a measure of the vertical distance (height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as ''orthometric heights''. The combination of unit of measurement and the physical quantity (height) is called "metres above mean sea level" in the metric system, while in United States customary and imperial units it would be called "feet above mean sea level". Mean sea levels are affected by climate change and other factors and change over time. For this and other reasons, recorded measurements of elevation above sea level at a reference time in history might differ from the actual elevation of a given location over sea level at a given moment. Uses Metres above sea level is the standard measurement of the elevation or altitude of: * Geographic locations such as towns, mountains and other landmarks. * The top of buildings and other structures. * Flying objects such ...

Tennessee Valley Authority
The Tennessee Valley Authority (TVA) is a federally owned electric utility corporation in the United States. TVA's service area covers all of Tennessee, portions of Alabama, Mississippi, and Kentucky, and small areas of Georgia, North Carolina, and Virginia. While owned by the federal government, TVA receives no taxpayer funding and operates similarly to a private for-profit company. It is headquartered in Knoxville, Tennessee, and is the sixth largest power supplier and largest public utility in the country. The TVA was created by Congress in 1933 as part of President Franklin D. Roosevelt's New Deal. Its initial purpose was to provide navigation, flood control, electricity generation, fertilizer manufacturing, regional planning, and economic development to the Tennessee Valley, a region that had suffered from lack of infrastructure and poverty during the Great Depression, relative to the rest of the nation. TVA was envisioned both as a power supplier and a regional economi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blue Ridge Dam
Blue Ridge Dam is a hydroelectric dam on the Toccoa River in Fannin County, in the U.S. state of Georgia. It is the uppermost of four dams on the Toccoa/Ocoee River owned and operated by the Tennessee Valley Authority. The dam impounds the Blue Ridge Lake on the southwestern fringe of the Blue Ridge Mountains.Tennessee Valley Authority, ''Design of TVA Projects Volume 3: Mechanical Design of Hydro Plants'', Technical Report No. 24 (Washington, D.C.: Tennessee Valley Authority, 1952), pp. 302-304. Location Blue Ridge Dam is located upstream from the mouth of the Toccoa/Ocoee River, near the point where the states of Georgia, Tennessee, and North Carolina meet. The Toccoa River winds its way northwestward from the dam, crossing into Tennessee (where it becomes the Ocoee River) roughly downstream en route to the Ocoee dams on the lower part of the river. Blue Ridge Dam is upstream from Ocoee Dam No. 3. The Chattahoochee National Forest surrounds Blue Ridge Dam and its res ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Penstock
A penstock is a sluice or gate or intake structure that controls water flow, or an enclosed pipe that delivers water to hydro turbines and sewerage systems. The term is inherited from the earlier technology of mill ponds and watermills. Hydroelectric systems and dams Penstocks for hydroelectric installations are normally equipped with a gate system and a surge tank. They can be a combination of many components such as anchor block, drain valve, air bleed valve, and support piers depending on the application. Flow is regulated by turbine operation and is nil when turbines are not in service. Penstocks, particularly where used in polluted water systems, need to be maintained by hot water washing, manual cleaning, antifouling coatings, and desiccation. The term is also used in irrigation dams to refer to the channels leading to and from high-pressure sluice gates. Penstocks are also used in mine tailings dam construction. The penstock is usually situated fairly close to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hiwassee River
The Hiwassee River has its headwaters on the north slope of Rocky Mountain in Towns County in the northern area of the State of Georgia. It flows northward into North Carolina before turning westward into Tennessee, flowing into the Tennessee River a few miles west of what is now State Route 58 in Meigs County, Tennessee. The river is about long. Hydrography The river is dammed by the Tennessee Valley Authority (TVA) in four locations, all in Western North Carolina: Chatuge Dam, Mission Dam (not owned by TVA), Hiwassee Dam, and Apalachia Dam. Water is diverted from the stream bed at Apalachia Dam and sent through a pipeline, which is tunneled through the mountains for eight miles (13 km); then it flows through the Apalachia Powerhouse to generate electricity. The stretch of the river that flows between Apalachia Dam and Apalachia Powerhouse features reduced flow. The John Muir Trail in Tennessee's Cherokee National Forest goes along this part of the river. The stretch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dams In Georgia (U
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. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dams were used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
