The Three Gorges Dam is a hydroelectric gravity dam that spans the Yangtze River near Sandouping in Yiling District, Yichang, Hubei province, central China, downstream of the Three Gorges. The world's largest power station in terms of installed capacity (22,500 MW), the Three Gorges Dam generates 95±20 TWh of electricity per year on average, depending on the amount of precipitation in the river basin. After the extensive monsoon rainfalls of 2020, the dam's annual production reached nearly 112 TWh, breaking the previous world record of ~103 TWh set by Itaipu Dam in 2016.
The Colorado River is one of the principal rivers in the Southwestern United States and in northern Mexico. The 1,450-mile-long (2,330 km) river, the 5th longest in the United States, drains an expansive, arid watershed that encompasses parts of seven U.S. states and two Mexican states. The name Colorado derives from the Spanish language for "colored reddish" due to its heavy silt load. Starting in the central Rocky Mountains of Colorado, it flows generally southwest across the Colorado Plateau and through the Grand Canyon before reaching Lake Mead on the Arizona–Nevada border, where it turns south toward the international border. After entering Mexico, the Colorado approaches the mostly dry Colorado River Delta at the tip of the Gulf of California between Baja California and Sonora.
The Central Valley Project (CVP) is a federal power and water management project in the U.S. state of California under the supervision of the United States Bureau of Reclamation (USBR). It was devised in 1933 in order to provide irrigation and municipal water to much of California's Central Valley—by regulating and storing water in reservoirs in the northern half of the state, and transporting it to the water-poor San Joaquin Valley and its surroundings by means of a series of canals, aqueducts and pump plants, some shared with the California State Water Project (SWP). Many CVP water users are represented by the Central Valley Project Water Association.
The Sardar Sarovar Dam is a concrete gravity dam built on the Narmada River near the town of Kevadiya, in Narmada District, in the Indian state of Gujarat. The dam was constructed to provide water and electricity to the Indian states of Gujarat, Madhya Pradesh, Maharashtra and Rajasthan.
Oroville Dam is an earthfill embankment dam on the Feather River east of the city of Oroville, California, in the Sierra Nevada foothills east of the Sacramento Valley. At 770 feet (235 m) high, it is the tallest dam in the U.S. and serves mainly for water supply, hydroelectricity generation, and flood control. The dam impounds Lake Oroville, the second-largest reservoir in California, capable of storing more than 3.5 million acre-feet (1.1×1012 US gal; 4.3×109 m3).
Bhavani is an interstate Indian river which flows through Indian states of Kerala and Tamil Nadu, India. It originates from the Western Ghats and is one among the three rivers of Kerala which flows in eastward direction.
The Lesotho Highlands Water Project (LHWP) is an ongoing water supply project with a hydropower component, developed in partnership between the governments of Lesotho and South Africa. It comprises a system of several large dams and tunnels throughout Lesotho and delivers water to the Vaal River System in South Africa. In Lesotho, it involves the rivers Malibamatso, Matsoku, Senqunyane, and Senqu. It is Africa's largest water transfer scheme.
The Mettur Dam is one of the largest dams in India and also the largest in Tamil Nadu, located across the river Kaveri where it enters the plains. Built in 1934, it took 9 years to complete. Maximum height and width of the dam are 214 and 171 feet, respectively. The dam receives inflows from its own catchment area, Kabini Dam and Krishna Raja Sagara Dams located in Karnataka. There is a park at the base of the dam called Ellis Park maintained by the Tamil Nadu Public Works Department. It provides irrigation and drinking water facilities for more than 12 districts of Tamil Nadu and hence is revered as the life and livelihood-giving asset of Tamil Nadu.
The Ilısu Dam is a concrete-face rock-fill dam on the Tigris near the village of Ilısu and along the border of Mardin and Şırnak Provinces in Turkey. It is one of the 22 dams of the Southeastern Anatolia Project and its purpose is hydroelectric power production, flood control and water storage. When operational, the dam will support a 1,200 MW power station and will form a 10.4 billion m3 reservoir. Construction of the dam began in 2006 and was originally expected to be completed by 2016. As part of the project, the much smaller Cizre Dam is to be constructed downstream for irrigation and power. The dam has drawn international controversy, because it will flood portions of ancient Hasankeyf and necessitate the relocation of people living in the region. Because of this, the dam lost international funding in 2008. Most historical structures in Hasankeyf were moved to the new Hasankeyf prior to the filling of the dam. The dam began to fill its reservoir in late July 2019. Due to rainfall, the dam has achieved water levels up to 100m above the river bed and stored 5 billion cubic meters of water. The water level had reached an elevation of 498.2m on 1 April 2020.
The Idukki Dam is a double-curvature arch dam constructed across the Periyar River in a narrow gorge between two granite hills locally known as Kuravan and Kurathi in Idukki district in the state of Kerala, India. At 168.91 metres (554.2 ft), it is one of the highest arch dams in Asia. It is constructed and owned by the Kerala State Electricity Board. It supports a 780 MW hydroelectric power station in Moolamattom, which started generating power on 4 October 1975. The dam type is a concrete, double curvature parabolic, thin arc dam. The Indo-Canadian project was inaugurated by the Prime Minister Indira Gandhi on February 17, 1976.
Malampuzha Dam is the second largest dam and reservoirs in Kerala, located near Palakkad, in the state of Kerala in South India, built post independence by the then Madras state. Situated in the scenic hills of the Western Ghats in the background it is a combination of a masonry dam with a length of 1,849 metres and an earthen dam with a length of 220 metres making it the longest dam in the state. The dam is 355 feet high and crosses the Malampuzha River, a tributary of Bharathappuzha, Kerala's second longest river. There is a network of two canal systems that serve the dam's reservoir of 42,090 hectares.
Kidston Dam also known as Copperfield Dam is a dam in Lyndhurst, Shire of Etheridge, Queensland, Australia.
