Contents

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 surface area of 16,835 square kilometres and has an average depth of 4,5 metres. The rivers – i.e., Suikerbosrand, Klip, & Rietspruit – that feed into the Vaal River Barrage Reservoir flow from industrial and heavily populated areas such as Johannesburg, Vereeniging and Sasolburg. This reservoir was used to supply water to the Witwatersrand but no longer does so because the quality of its water is deteriorating due to pollution. This reservoir, which is managed by Rand Water, is used for many recreational activities, such as boating, skiing, fishing, and swimming, with many holiday resorts found along its banks. [1]

The Orange River is a river in Southern Africa. It is the longest river in South Africa. With a total length of 2,432 km (1,511 mi), the Orange River Basin extends from Lesotho into South Africa and Namibia to the north.

Bloemhof Dam is a dam in South Africa. It was originally known as the Oppermansdrif Dam when under construction during the late 1960s. It is located at the confluence of the Vaal River and the Vet River, on the border between the provinces North West and Free State. The dam wall has a total length of 4,270 metres (14,010 ft) The reservoir is very shallow, and therefore needs a large area to mean anything for water storage. The area around the reservoir (dam), has been a protected area, but because it lies on the border between provinces, these became two separate nature reserves. On the North West Province side lies the Bloemhof Dam Nature Reserve, on the Free State side is the Sandveld Nature Reserve.
