Smith Mountain Dam is a concrete arch dam located on the Roanoke River in Virginia, creating Smith Mountain Lake. The dam was built by Appalachian Power (a division of American Electric Power ) between 1960 and 1963 for the purposes of pumped-storage hydroelectricity .
The mines required large amounts of water and timber to supply the houses and mines in Virginia City and Gold Hill. To feed these mines, the dam at Carson Tahoe Lumber and Fluming Company's Marlette Lake was increased, and Hobart Reservoir was created, and a number of flumes and pipelines were built to transport water down to Virginia City.
Bosher's Dam is a historic low head dam (also called a weir) built upon the James River just west of Richmond, Virginia.It is a 12-foot-high stone structure which interrupts the natural flow of Virginia's largest self-contained river by spanning the waterway between suburban Tuckahoe in Henrico County and the western part of Richmond just west of the Edward E. Willey Bridge.
The dam was built in 53 sections called monoliths. A grouting tunnel or gallery was built in order to fill gaps between the dam and foundation with concrete. The spillway consists of 22-tainter gates for overflow and at the base of the dam, 6-sluice gates were installed to maintain downstream flows. Construction was completed and the dam was ...
Ancient dams were built in Mesopotamia and the Middle East for water control. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. Egyptians also built dams, such as Sadd-el-Kafara Dam for flood control. In modern-day India, Dholavira had an intricate water-management system with 16 reservoirs and dams.
The dam's hydroelectric power plant is located on the west side of the spillway and is supplied with water via a 5-foot-diameter (2 m) penstock. The plant consists of two small open runner turbine-generators, the larger with a 775 kW capacity and the smaller rated at 225 kW for a combined installed capacity of 1 megawatt .
The locks were a crib like construct made entirely of wood and filled with stone. [4] [11] Original plans, recommended by the Virginia Board of Public Works, called for the canal to start on the south side of the Rapidan Dam (its final location) so that boats could safely access the canal. The engineers of the Rappahannock Company, determined ...
