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.
The Allemanskraal Dam is a dam in the Free State province of South Africa, on the Sand River. It was established in 1960. The reservoir has a gross capacity of 174,500 cubic metres (6,160,000 cu ft), and a surface area of 26.481 square kilometres (10.224 sq mi), the dam wall is 38 metres (125 ft) high.
Armenia Dam is a dam in the Leeu River, near Hobhouse, Free State province, South Africa. It was established in 1954. It has a capacity of 13,000 cubic metres (460,000 cu ft), and a surface area of 3.933 square kilometres (1.519 sq mi), the wall is 22 metres (72 ft) high.
Beervlei Dam is a dam in the Groot River, Eastern Cape, South Africa. It was established in 1957, has a capacity of 85,800,000 cubic metres (3.03×109 cu ft), and a surface area of 23.145 square kilometres (8.936 sq mi), and the dam wall is 31 m high. The main purpose of the dam is to provide flood absorption. The Karoo sediments in the area contain a lot of salts and it has been found that lengthy storage of water results in high water salinity. Any flood water is used as quickly as possible by the downstream irrigators and the reservoir is kept empty for extended periods.
Darlington Dam, also referred to as Lake Mentz. is a gravity type dam situated in the Sundays River, near Kirkwood, in Eastern Cape, South Africa. It was established in 1922 and was renovated in 1952. The dam has a capacity of 187,000,000 cubic metres (6.6×109 cu ft), with a 35.3 metres (116 ft)-high wall. Its primary purpose is for irrigation, industrial and domestic use.

It currently has a capacity of 301 million m3 and is principally for provision of water to the industrial complex at Richards Bay. It serves also as reservoir for irrigation and domestic use. The hazard potential of the dam has been ranked high (3).
Kwena Dam is a combined gravity & arch type dam located on the Crocodile River, near Lydenburg, Mpumalanga province, South Africa. It was established in 1984 and it serves mainly for irrigation purposes. The hazard potential of the dam has been ranked high (3).
Middle Letaba Dam is an earth-fill type dam located on the Middle Letaba River, 40 km east of Elim and 40 km west of Giyani, Limpopo, South Africa. The source of the Middle Letaba river rises high in the tropical mountains of Magoebaskloof near Tzaneen, where rainfall is abundant during the summer months. The river passes numerous villages and its flow becomes quite strong when it reaches the village of Magoro.
Nzhelele Dam is an arch type dam located on the Nzhelele River in Limpopo Province, South Africa. It has a capacity of 55.3 million m3. It was established in 1948. The main purpose of the dam is to serve for irrigation and its hazard potentials has been ranked high (3).
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).
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).
Zaaihoek Dam is a gravity type dam located on the Slang River in Mpumalanga Province of South Africa. The dam was established in 1988 with a capacity of 185 000 000 m3. The dam serves primarily for municipal and industrial water supply purposes. Its hazard potential has been ranked high (3).
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.
Stompdrift Dam is a combined multi-arch and gravity type dam located on the Olifants River near De Rust, Western Cape, South Africa.
