Last updated

Lower Orange WMA, or Lower Orange Water Management Area (coded: 14), Includes the following major rivers: the Ongers River, Hartbees River and Orange River, and covers the following Dams:

Orange River river

The Orange River is the longest river in South Africa and the Orange River Basin extends extensively into Namibia and Botswana 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 Namibia and between South Africa and Lesotho, 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 Gariep River, Groote River or Senqu River.

Boegoeberg Dam is a gravity type dam on the Orange River, near Prieska, Northern Cape, South Africa. Building was started in 1926 and completed by 1933. Boegoeberg is named for the small tree Croton gratissimus, also known as Bergboegoe. Its primary purpose is for irrigation and it has a low hazard potential.

Vaal River river in South Africa

The Vaal River is the largest tributary of the Orange River in South Africa. The river has its source near Breyten in Mpumalanga province, east of Johannesburg and about 30 kilometres (19 mi) north of Ermelo and only about 240 kilometres (150 mi) from the Indian Ocean. It then flows westwards to its conjunction with the Orange River southwest of Kimberley in the Northern Cape. It is 1,120 kilometres (700 mi) long, and forms the border between Mpumalanga, Gauteng and North West Province on its north bank, and the Free State on its south.

Drainage basin Area of land where precipitation collects and drains off into a common outlet

A drainage basin is any area of land where precipitation collects and drains off into a common outlet, such as into a river, bay, or other body of water. The drainage basin includes all the surface water from rain runoff, snowmelt, and nearby streams that run downslope towards the shared outlet, as well as the groundwater underneath the earth's surface. Drainage basins connect into other drainage basins at lower elevations in a hierarchical pattern, with smaller sub-drainage basins, which in turn drain into another common outlet.

Molopo River river

The Molopo River is one of the main rivers in Southern Africa. It has a length of approximately 960 kilometres and a catchment area of 367,201 km2 with Botswana, Namibia and South Africa sharing roughly about a third of the basin each.

Chambal River river in India

The Chambal River is a tributary of the Yamuna River in central India, and thus forms part of the greater Gangetic drainage system. The river flows north-northeast through Madhya Pradesh, running for a time through Rajasthan, then forming the boundary between Rajasthan and Madhya Pradesh before turning southeast to join the Yamuna in Uttar Pradesh state.

Inkomati WMA, or Inkomati Water Management Area , in South Africa is situated in the north-eastern part of South Africa in the Mpumalanga Province, with a small area in the Limpopo Province. It borders on Mozambique in the east and on Swaziland in the south-east. The water management area extends over several parallel river catchments which all drain in a general easterly direction, and flow together at the border with Mozambique or within Mozambique, to form the Incomati River which discharges into the Indian Ocean immediately north of Maputo. A special situation is presented by the Komati River, the most southern tributary of the Incomati River, which rises in South Africa and flows into Swaziland, then re-enters South Africa where it is joined by the Crocodile River at the border with Mozambique, before flowing into Mozambique as the Incomati River. The Sabie River is the other main river in the water management area and flows into Corumuna Dam in Mozambique just downstream of the border with South Africa, and upstream of its confluence with the Inkomati River.
