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.

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".

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.

Wonderfonteinspruit is a small river situated in the Highveld region of South Africa. Its source has been disputed in the past, although it is now accepted that the river originates in the West Rand of Gauteng between Krugersdorp and Randfontein, at the Tudor Dam, which was initially used as a storage dam for the Luiperdsvlei Gold Plant. In the past the river received a majority of its water from karst springs along its course. The river flows through one of the richest gold-producing areas in the world, which led to the dolomitic compartments which fed the river being dewatered to make way for mining activities. This led to the drying up of the karst springs that fed the river.
