Olushandja Dam is a dam on the Etaka River outside of Oshakati in the Oshana Region of Namibia. The dam was completed in 1990. [1] Its lake has a maximum capacity of 42.331 million cubic metres, and stores water from the Calueque Dam on the Cunene River in nearby Angola which supports hydroelectricity generation in the Ruacana Power Station downstream.

The Zambezi is the fourth-longest river in Africa, the longest east-flowing river in Africa and the largest flowing into the Indian Ocean from Africa. Its drainage basin covers 1,390,000 km2 (540,000 sq mi), slightly less than half of the Nile's. The 2,574 km (1,599 mi) river rises in Zambia and flows through eastern Angola, along the north-eastern border of Namibia and the northern border of Botswana, then along the border between Zambia and Zimbabwe to Mozambique, where it crosses the country to empty into the Indian Ocean.
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 Naute Dam is a dam outside of Keetmanshoop in the Karas Region of Namibia. It was built by Concor between 1970 and 1972 and was officially commissioned in September 1972. It is the third largest dam in Namibia after Hardap Dam to Naute's north and can hold up to 69 million cubic metres of water. The dam's source is the Löwen River, a tributary of the Fish River.
The Von Bach Dam is a rock-fill embankment dam on the Swakop River near Okahandja in the Otjozondjupa Region of Namibia. Built in 1968 and commissioned in 1970, the dam provides Namibia's capital of Windhoek with much of the city's water. It also supplies Okahandja. The dam has a capacity of 48.56 million cubic metres (63,510,000 cu yd). Water from the reservoir is sent directly to a water treatment plant downstream. The treatment plant was completed in 1971 and upgraded in 1997.
Oanob Dam is a dam outside Rehoboth, Hardap Region, Namibia. Located 7 kilometres (4.3 mi) outside Rehoboth, it dams the Oanob River and supplies the town with the majority of its water. It has a capacity of 34,505,000 cubic metres (1.2185×109 cu ft) and was completed in 1990, the year of Namibia's independence.

Namibia is an arid country that is regularly afflicted by droughts. Large rivers flow only along its northern and southern borders, but they are far from the population centers. They are also far from the country's mines, which are large water users. In order to confront this challenge, the country has built dams to capture the flow from ephemeral rivers, constructed pipelines to transport water over large distances, pioneered potable water reuse in its capital Windhoek located in the central part of Namibia, and built Sub-Saharan Africa's first large seawater desalination plant to supply a uranium mine and the city of Swakopmund with water. A large scheme to bring water from the Okavango River in the North to Windhoek, the Eastern National Water Carrier, was only partially completed during the 1980s.
