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.

[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 ...
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 ...
