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 construction of Vaal Dam started during the depression of the early thirties and the dam was completed in 1938 with a wall height of 54.2 metres (178 ft) above lowest foundation and a full supply capacity of 994,000,000 cubic metres (3.51 × 10 10 cu ft). The dam is a concrete gravity structure with an earthfill section on the right flank.
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]
[4]: 56 More water was still required and by 1937 the Vaal Dam was completed 80 km south-east of Johannesburg. [1]: 217 [2] The next major project was the Lesotho Highlands Water Project in 1998 that saw the construction of several large dams and pipeline transporting water from Lesotho to the Vaal Dam in South Africa.

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 ...

The Vaal River scheme was an initiative established to manage water distribution. The Rand Water board also established the Vereeniging Pumping Station (1924), the Zwartkopjes Pumping Station, the Vaal Dam (1938), the Zuikerbosch Pumping Station (1949) and the Lesotho Highlands Water Project (1998).

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 ...
