The Kariba Dam is a double curvature concrete arch dam in the Kariba Gorge of the Zambezi river basin between Zambia and Zimbabwe. The dam stands 128 metres (420 ft) tall and 579 metres (1,900 ft) long. The dam forms Lake Kariba, which extends for 280 kilometres (170 mi) and holds 185 cubic kilometres (150,000,000 acre⋅ft) of water.
Hydroelectricity, or hydroelectric power, is electricity produced from hydropower. In 2015, hydropower generated 16.6% of the world's total electricity and 70% of all renewable electricity, and was expected to increase by about 3.1% each year for the next 25 years.
The James Bay Project refers to the construction of a series of hydroelectric power stations on the La Grande River in northwestern Quebec, Canada by state-owned utility Hydro-Québec, and the diversion of neighbouring rivers into the La Grande watershed. It is located between James Bay to the west and Labrador to the east, and its waters flow from the Laurentian Plateau of the Canadian Shield. The project covers an area the size of New York State and is one of the largest hydroelectric systems in the world. It has cost upwards of US$20 billion to build and has an installed generating capacity of 16,527 megawatts. If fully expanded to include all of the original planned dams, as well as the additional James Bay II projects, the system would generate a total of 27,000 MW, making it the largest hydroelectric system in the world. It has been built since 1974 by the James Bay Energy (SEBJ) for Hydro-Québec.
Lake Wylie is a reservoir or man-made lake in the U.S. states of South Carolina and North Carolina. The lake has a surface area of 13,400 acres and features 325 miles (523 km) of shoreline.
Induced seismicity refers to typically minor earthquakes and tremors that are caused by human activity that alters the stresses and strains on Earth's crust. Most induced seismicity is of a low magnitude. A few sites regularly have larger quakes, such as The Geysers geothermal plant in California which averaged two M4 events and 15 M3 events every year from 2004 to 2009. The Human-Induced Earthquake Database (HiQuake) documents all reported cases of induced seismicity proposed on scientific grounds and is the most complete compilation of its kind.
The North Anna Nuclear Generating Station is a nuclear power plant on a 1,075-acre (435 ha) site in Louisa County, Virginia, in the Mid-Atlantic United States. The site is operated by Dominion Generation company and is jointly owned by the Dominion Virginia Power corporation (88.4%) and by the Old Dominion Electric Cooperative (11.6%).
The Monticello Nuclear Generating Plant is a nuclear power plant located in Monticello, Minnesota, along the Mississippi River. The site, which began operating in 1971, has a single nuclear reactor of the General Electric BWR-3 design generating 671 MWe. The reactor was originally licensed until 2010; a renewal license issued in 2006 allows it to continue operating until September 8, 2030.
The Broad River is a principal tributary of the Congaree River, about 150 miles (240 km) long, in western North Carolina and northern South Carolina in the United States. Via the Congaree, it is part of the watershed of the Santee River, which flows to the Atlantic Ocean.
A reservoir is most commonly an enlarged natural or artificial lake created using a dam to store fresh water.
Dam safety systems are used to monitor the state of dams, including external physical threats to the dams, and issuing emergency warnings at various degrees of automation. This includes the use of differential GPS and SAR remote sensing to monitor the risks imposed by landslides and subsidence. For large dams, seismographs are used to detect reservoir-induced seismicity that could threaten the stability of the dam. The output of these systems can provide warning to the local population ahead of a potential collapse.
Hartwell Dam is a concrete and embankment dam located on the Savannah River at the border of South Carolina and Georgia, creating Lake Hartwell. The dam was built by the U.S. Army Corps of Engineers between 1955 and 1962 for the purposes of flood control, hydropower and navigation. The concrete and earthen structure spans 15,840 feet (4,828 m). The concrete section is 1,900 feet (579 m) long and rises 204 feet (62 m) above the riverbed at its apex. The Hartwell Dam currently produces 468 million KWh of electricity annually, has prevented over $40 million in flood damage since completion and also provides recreation, water quality, water supply, along with fish and wildlife management.
Monticello Dam is a 304-foot (93 m) high concrete arch dam in Napa County, California, United States, constructed between 1953 and 1957. The dam impounded Putah Creek to create Lake Berryessa in the Vaca Mountains.
Lake Keowee is a man-made reservoir in the United States in the state of South Carolina. It was developed to serve the needs of power utility Duke Energy and public recreational purposes. It is approximately 26 miles (42 km) long, 3 miles (4.8 km) wide, with an average depth of 54 feet (16 m), and a shoreline measured at 300 miles (480 km) in total, and is approximately 800 feet (240 m) above sea level.
The Geysers is the world's largest geothermal field, containing a complex of 18 geothermal power plants, drawing steam from more than 350 wells, located in the Mayacamas Mountains approximately 72 miles (116 km) north of San Francisco, California.
Auburn Dam was a proposed concrete arch dam on the North Fork of the American River east of the town of Auburn, California, in the United States, on the border of Placer and El Dorado Counties. Slated to be completed in the 1970s by the U.S. Bureau of Reclamation, it would have been the tallest concrete dam in California and one of the tallest in the United States, at a height of 680 feet (210 m) and storing 2,300,000 acre-feet (2.8 km3) of water. Straddling a gorge downstream of the confluence of the North and Middle Forks of the American River and upstream of Folsom Lake, it would have regulated water flow and provided flood control in the American River basin as part of Reclamation's immense Central Valley Project.
Talbingo Dam is a major ungated rock fill with clay core embankment dam with concrete chute spillway across the Tumut River upstream of Talbingo in the Snowy Mountains region of New South Wales, Australia. The impounded reservoir is called Talbingo Reservoir.
Apalachia Dam is a hydroelectric dam on the Hiwassee River in Cherokee County, in the U.S. state of North Carolina. The dam is the lowermost of three dams on the river owned and operated by the Tennessee Valley Authority, which built the dam in the early 1940s to provide emergency power for aluminum production during World War II. While the dam is in North Carolina, an 8.3-mile (13.4 km) underground conduit carries water from the dam's reservoir to the powerhouse located 12 miles (19 km) downstream across the state line in Polk County, Tennessee. The dam and associated infrastructure were listed on the National Register of Historic Places in 2017.
Parr Reservoir or Parr Shoals Reservoir is an impoundment of the Broad River in Pomaria, South Carolina. It is the last dam on the Broad River before the river reaches Columbia, South Carolina and the Columbia Canal. The lake is mainly used as a holding pond of sorts, as the water is pulled in and out and used to cool the turbines of a nearby nuclear power plant. Some anglers will fish for catfish in the main river channel, while bass fishing is mainly held back to Heller's and Cannon creeks, as well as the tailrace below Lake Monticello.
The Catawba Nuclear Station is a nuclear power plant located on a 391-acre (158 ha) peninsula, called "Concord Peninsula", that reaches out into Lake Wylie, in York, South Carolina, USA. Catawba utilizes a pair of Westinghouse four-loop pressurized water reactors.
Lake Matahina is a reservoir in the Bay of Plenty region of New Zealand, located immediately south of the settlement of Te Mahoe and 50 km east of Rotorua. The lake was formed by the construction of the Matahina Power Station and its associated 86 m tall Matahina Dam on the Rangitaiki River, which was completed in 1967.
