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.
It consisted mainly of the construction of: The Mohale Dam, a very large rockfill dam, located on the Senqunyane River; A 32-kilometre (20 mi) transfer tunnel between the Mohale Dam and the Katse Dam; Construction of the Matsoku Diversion Weir; A 5.7-kilometre (3.5 mi) tunnel from the Matsoku Diversion Weir to the Katse Dam.
Electricity generation equipment is located between Driekloof Dam and Kilburn Dam. [3] Since the Driekloof Dam/Sterkfontein Dam also forms part of the Tugela-Vaal Water Project some of the water pumped to Driekloof Dam might end up flowing to the Vaal Dam and not be available for return to the Kilburn Dam. The Woodstock Dam and Driel Barrage ...
The Vaal River Barrage Reservoir is a dam on the Vaal River near Vanderbijlpark, border Gauteng and Free State, South Africa.

The reservoir is 64 kilometres long and has a total storage capacity of 63 million litres, a ...
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 existing dam has reached the end of its lifespan. The dam, built in 1841 and reconstructed in 1959, has been worked on many times throughout the year. Under construction: Initial work underway ...
The dam also provides some flood attenuation for Standerton and stores up to 100 million m 3 /annum pumped into the upper reaches of the Vaal River basin from Heyshope Dam in the Usutu River basin. The hazard potential of the entire dam construction has been ranked high (3).
Vaalharts Storage Weir is a dam in South Africa. It was established in 1936. Vaalhartz Weir (alternative spelling) is located on the Vaal River approximately 100 km downstream of Bloemhof Dam and 13 km upstream of Warrenton. The main purpose of the dam is to divert water from the Vaal River (released from Bloemhof Dam) to the Olebogeng Mokoena ...
