The Volta River is the main river system in the West African country of Ghana. It flows south into Ghana from Bobo-Dioulasso highlands of Burkina Faso. The main parts of the river are the Black Volta, the White Volta, and the Red Volta. In the northwest, the Black Volta forms the international borders between the Ivory Coast, Ghana, and Burkina Faso. The Volta flows southward along Akwapim-Togoland highlands, and it empties into the Atlantic Ocean at the Gulf of Guinea at Ada Foah. It has a smaller tributary river, the Oti, which enters Ghana from Togo in the east. The Volta River has been dammed at Akosombo for the purpose of generating hydroelectricity. The reservoir named Lake Volta stretches from Akosombo Dam in the south to the northern part of the country, and is the largest man-made reservoir by area in the world.
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.
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. It supplies irrigation water to the Kouga and Gamtoos valleys as well as drinking water to the Port Elizabeth metropolitan area via the Loerie Balancing Dam. It was constructed between 1957 and 1969.
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. In 1916 a Board of Engineers was appointed to report on a water augmentation scheme for the city. Their proposal was the Steenbras scheme which would consist of a concrete gravity and arch dam on the Steenbras River. This dam would be connected to the Molteno reservoir through a tunnel in the Hottentots Holland mountains and a 64 kilometre long cast iron pipeline. Work began on the scheme in 1918 and was completed three years later. The Steenbras scheme could supply Cape Town with up to 42 million litres of water per day although the average consumption was in the region of 29 million litres per day. The consumption however grew rapidly and it was not long before Cape Town once again had a water supply problem. To solve the demand for additional water supplies the Steenbras dam wall was raised and an additional pipeline was laid into the city. This work was completed in 1928. For much of the first half of the twentieth century it was the main reservoir for Cape Town but is now only one of many dams that supply the city. The hazard potential of Steenbras has been ranked high (3).
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, and is due to be operated, 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.
Albert Falls Dam is a dam in the Umgeni River, just outside Pietermaritzburg, KwaZulu-Natal, South Africa. It was established in 1976. It has a gross capacity of 290.1 million cubic meters and a surface area of 23.521 square kilometres (9.082 sq mi), the dam wall is 33 metres (108 ft) high.
Inanda Dam is an earth-fill type dam located on the Mgeni River, near Inanda, KwaZulu-Natal, South Africa. It was established in 1989 and its primary purpose is to serve for domestic and industrial use.
Kalkfontein Dam is a rockfill type dam located on the Riet River, near Koffiefontein, Free State, South Africa. It was established in 1938 and renovated in 1977. The primary purpose of the dam is to serve for irrigation purposes and its hazard potential has been ranked high (3). Kalkfontein Dam reservoir is often quite low as the upstream area is hot and dry and too small to fill a dam of this size, however during flooding on the Orange River, water is transferred from the Orange River at Vanderkloof Dam to Kalkfontein Dam. In 2021 this led to the reservoir rising from 17.3% to 61.7% in a single week.
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).
Wemmershoek Dam is an earth-fill type dam located on the Wemmershoek River near Franschhoek and Paarl in South Africa. The dam was established in 1957 with a capacity of 58 644 000 m3 behind a 55 m high wall. The dam serves mainly for municipal and industrial use as part of the Western Cape Water Supply System which supplies the city of Cape Town and surrounding areas. Its hazard potential has been ranked high (3).
Woodhead Dam is a dam on Table Mountain, Western Cape, South Africa. It was built in 1897 and supplies water to Cape Town. The dam, which was the first large masonry dam in South Africa, was designated as an International Historic Civil Engineering Landmark by the American Society of Civil Engineers in 2008.
The Bushman's River is an east to north-easterly flowing tributary of the Tugela River, in the KwaZulu-Natal province of South Africa. It rises in the Drakensberg Mountain range, with its upper catchment in the Giant's Castle Game Reserve, north of the Giant's Castle promontory. It feeds the Wagendrift Dam and then flows past the town of Estcourt to join the Tugela River near the town of Weenen.
The Eerste River, located in the Western Cape, South Africa, rises on Dwarsberg 60 km east of Cape Town at the head of Jonkershoek. The Eerste River catchment covers the eastern part of the Cape Flats lying to the west of the Hottentots Holland Mountains and south of the Tygerberg where the Kuils River tributary rises east of Kanonkop. The Eerste River is a short river; its length has been given as 40 km. The major tributary, Kuils River, is approximately 30 km long to its point of confluence with the Eerste River.
Sol Plaatje Dam is an earth-fill type dam located at the confluence of the As and Liebenbergsvlei Rivers near Bethlehem, Free State, South Africa. It was established in 1968 and serves mainly for municipal and domestic water supply. The hazard potential of the dam has been ranked high. The reservoir receives water from the Lesotho Highlands Water Project via the As River.
The Vaal River Barrage Reservoir is a dam on the Vaal River near Vanderbijlpark, border Gauteng and Free State, South Africa.
Toorourrong Reservoir is a small water supply reservoir located on the southern slopes of the Great Dividing Range approximately 40 kilometres (25 mi) north of Melbourne, Victoria, Australia. The reservoir is formed by the Toorourrong Dam across the Plenty River, and an interbasin transfer. The dam is operated by Melbourne Water and the reservoir forms part of the Melbourne water supply system. Water from the Toorourrong Reservoir flows by aqueduct to the Yan Yean Reservoir.
