Gariep Dam 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 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. 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 Western Cape Water Supply System (WCWSS) is a complex water supply system in the Western Cape region of South Africa, comprising an inter-linked system of six main dams, pipelines, tunnels and distribution networks, and a number of minor dams, some owned and operated by the Department of Water and Sanitation and some by the City of Cape Town.
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.

Roode Elsberg Dam is located on the Sanddrift River, some 10 km north west of the town of De
Welbedacht Dam is a concrete-gravity type dam situated in South Africa, and was established in 1973. Bloemfontein is the sixth-largest city in South Africa, with a population around 300 000. It is situated in the Modder River catchment, which has insufficient water resources to meet the growing water requirements. The water supply to Bloemfontein is, therefore, augmented from the adjacent Caledon River by means of the Caledon - Modder River Government Water Scheme (CMRGWS).
Bongolo Dam, is located on the Komani River, near Queenstown, Eastern Cape, South Africa. The dam has a capacity of 7,015,000 cubic metres (247,700,000 cu ft). The Bongolo Dam, about 5 kilometres (3.1 mi) from town on the Dordrecht road, is one of Queenstown's main sources of water, its main purpose is for industrial and municipal usage. The wall was begun in 1905 and was for years the largest concrete dam wall in South Africa. Incidentally the origin of the name Bongola has caused some controversy, but it is believed by some to have been derived from the Xhosa language word mbongolo meaning donkey, as these animals were extensively used in the construction of the dam.
Klipvoor Dam is a concrete gravity type dam located on the Moretele River, 55 km north of Brits, North West, South Africa. It was established in 1970. The main purpose of the dam is to serve for irrigation and its hazard potential has been ranked as high (3).
