The Orange River is a river in Southern Africa. It is the longest river in South Africa. With a total length of 2,432 km (1,511 mi), the Orange River Basin extends from Lesotho into South Africa and Namibia to the north. It rises in the Drakensberg mountains in Lesotho, flowing westwards through South Africa to the Atlantic Ocean. The river forms part of the international borders between South Africa and Lesotho and between South Africa and Namibia, as well as several provincial borders within South Africa. Except for Upington, it does not pass through any major cities. The Orange River plays an important role in the South African economy by providing water for irrigation and hydroelectric power. The river was named the Orange River in honour of the Dutch ruling family, the House of Orange, by the Dutch explorer Robert Jacob Gordon. Other names include simply the word for river, in Khoekhoegowab orthography written as !Garib, which is rendered in Afrikaans as Gariep River with the intrusion of a velar fricative in place of the alveolar click, Groote River or Senqu River, derived from ǂNū "Black". It is known in isiZulu as isAngqu.
The Palmiet Pumped Storage Scheme consists of two 200 megawatts (270,000 hp) turbine units located 2 kilometres (1.2 mi) upstream of the Kogelberg Dam on the Palmiet River near Cape Town, South Africa. The pumped-storage hydroelectricity plant is capable of responding to a surge in peak power demand in minutes. At night, excess power on the grid generated by conventional coal and nuclear plants is used to pump water to the upper Rockview Dam overlooking Gordon's Bay.
The Gariep Dam is located in South Africa, near the town of Norvalspont, bordering the Free State and Eastern Cape provinces. Its primary purpose is for irrigation, domestic and industrial use as well as for power generation. It the largest dam in South Africa.
The Vanderkloof Dam is situated approximately 130 km (81 mi) downstream from Gariep Dam and is fed by the Orange River, South Africa's largest river. Vanderkloof Dam is the second-largest dam in South Africa, having the highest dam wall in the country at 108 metres (354 ft). The dam was commissioned in 1977; it has a capacity of 3,187.557 million cubic metres (2,584,195 acre⋅ft) and a surface area of 133.43 square kilometres (51.52 sq mi) when full. Other rivers flowing into this dam are the Berg River, two unnamed streams coming in from the direction of Reebokrand, the Knapsak River, Paaiskloofspruit, Seekoei River, Kattegatspruit and the Hondeblaf River, in a clockwise direction.
The Kouga Dam is an arch dam on the Kouga River about 21 km (13 mi) west of Patensie in Kouga Local Municipality, South Africa.

The Steenbras Dam, now referred to as Steenbras Lower Dam, is a gravity concrete arch type dam located in the Hottentots-Holland mountains, above Gordons Bay, near Cape Town in South Africa. It is one of the six large dams that make up the Western Cape Water Supply System. It is owned by the City of Cape Town and serves principally to supply water to that city. The dam wall is 28 metres (92 ft) high and 412 metres (1,352 ft) long; it impounds a reservoir of 36,133 megalitres over a surface area of 380 hectares when full.
The Johannesburg Botanical Garden is located in the suburb of Emmarentia in Johannesburg, South Africa. The gardens grew out of a large rose garden that was established in 1964 and subsequently expanded from 1969 to cover an area of around 125 hectares (1.25 km2). It is administered by Johannesburg City Parks. The Emmarentia Dam is situated immediately to the east of the garden and shares its extensive acreage. One of the main attractions is the Rose Garden with over 10 000 roses.

The Berg River Dam is a 68-metre (223 ft) high dam on the Berg River in South Africa. It is the centerpiece of the Berg Water Project (BWP) which is designed to capture the winter rainfall and store it for supply to Cape Town during the dry summer months. The project in turn forms an important part of the Western Cape Water Supply System (WCWSS), an intricate system of dams and bulk water infrastructure that provides water to more than 3 million people. At the inauguration of the dam in 2009, then President of South Africa Kgalema Motlanthe called the project "a good example of how public infrastructure projects can be used to contribute meaningfully to poverty eradication and to foster social empowerment of the people." The Berg River Dam was the first dam in South Africa to be designed and constructed in accordance with the guidelines of the World Commission on Dams. It has been completed on time and within budget. The Berg River basin and the adjacent metropolitan area of Cape Town are of particular importance to the Western Cape region because, although the basin generates only about 3% of the country's water resources, it is home to about 8% of South Africa's population, and produces about 12% of GDP.
Ncora Dam is a gravity type dam built by Concor and located on the Tsomo River, near Tsomo, Eastern Cape, South Africa. It was established in 1972 and serves mainly for irrigation purposes. The hazard potential of the dam has been ranked high (3).
Theewaterskloof Dam is an earth-fill type dam located on the Sonderend River near Villiersdorp, Western Cape, South Africa. Administratively it is located within Theewaterskloof Local Municipality. It was established in 1978 and is the largest dam in the Western Cape Water Supply System with a capacity of 480 million cubic metres, about 41% of the water storage capacity available to Cape Town, which has a population of over 4 million people. The dam mainly serves for municipal and industrial use as well as for irrigation purposes. The hazard potential of the dam has been ranked high (3).
Wemmershoek Dam is a rock-fill type dam located on the Wemmershoek River near Franschhoek and Paarl in South Africa. It was constructed between 1953 and 1957 on behalf of the City of Cape Town. With a reservoir capacity of 58,644 megalitres, it provides approximately 6.5% of the storage capacity of the Western Cape Water Supply System which supplies Cape Town and surrounding areas.
Woodhead Dam is a dam on Table Mountain, Western Cape, South Africa. It was built in 1897 and supplies water to Cape Town.
