The Sterkfontein Dam forms part of the Tugela-Vaal water transfer scheme for the interbasin transfer of water from the Thukela River in KwaZulu-Natal to boost the levels in the Vaal River System. Water from the Sterkfontein Dam is released once the Vaal Dam drops to below 16%. The dam has its own island some 5 km (3 mi) long.
Any water shortages to the power stations would be disastrous for South Africa since 80% of the country's electricity is dependent on water from the Komati-Usutu-Vaal system. It was estimated that the newly completed (1982) Grootdraai Dam would empty within a matter of months and an emergency scheme was therefore initiated to pump water ...
This was the largest irrigation scheme in the southern hemisphere at that time, [6] the project also created another key source of water for the Rand Water Board. This dam became a part of the Vaal River Catchment System. Which is made up of four subcatchment regions ( Grootdraai, Waterval, Wilge and the Vaal Dam reservoir). [7]
The Tugela Vaal water Transfer Scheme is an irrigation project developed in the Drakensberg mountains at the Oliviershoek Pass in South Africa. [1] The project will thus allow the annual transfer from the Tugela basin (in KwaZulu-Natal) of 630 million m3 of water to the Vaal basin (in the Free State) in the north, and ultimately the Vaal dam in ...
The Sterkfontein Dam, located just outside the town of Harrismith, in the Free State, province of South Africa, is part of the Tugela-Vaal Water Project and the Drakensberg Pumped Storage Scheme, and located on the Nuwejaarspruit, a tributary of the Wilge River in the upper catchment area of the Vaal River.

The Vaal River Barrage Reservoir is a dam on the Vaal River near Vanderbijlpark, border Gauteng and Free State, South Africa. The Barrage, created by a set of gates across the Vaal River, was built by Rand Water downstream of the Vaal Dam, in 1923. The reservoir is 64 kilometres long and has a total storage capacity of 63 million litres, a ...
The Witwatersrand sits on the South African Highveld and consists of mostly grasslands with summer rains with an average yearly of 784mm rainfall. [1]: 210 The Witwatersrand ridge stretches for 96 km from east to west with rivers north of the ridge flowing to north into the Limpopo and into the Indian Ocean while the rivers south of the ridge flow south into the Vaal and Orange River and into ...
It is named after the Vaal River and the Harts River, the Vaal River being its major tributary. [1] Water from a diversion weir in the Vaal River, near Warrenton, flows through a 1,176 km long network of canals. This system provides irrigation water to a total of 39,820ha scheduled land, industrial water to six towns and other industrial water ...
