Last updated April 24, 2019

Middle Vaal WMA. or Middle Vaal Water Management Area (coded: 9), Includes the following major rivers: the Vet River, Vals River and Vaal River, and covers the following Dams:

The Vet River is a westward-flowing tributary of the Vaal River in central South Africa. Its sources are between Marquard and Clocolan and the Vet River flows roughly northwestwards to meet the Vaal at the Bloemhof Dam near Hoopstad.

The Vals River is a tributary of the Vaal River in the Free State, South Africa. It is a strong seasonal river.

The Vaal River is the largest tributary of the Orange River in South Africa. The river has its source near Breyten in Mpumalanga province, east of Johannesburg and about 30 kilometres (19 mi) north of Ermelo and only about 240 kilometres (150 mi) from the Indian Ocean. It then flows westwards to its conjunction with the Orange River southwest of Kimberley in the Northern Cape. It is 1,120 kilometres (700 mi) long, and forms the border between Mpumalanga, Gauteng and North West Province on its north bank, and the Free State on its south.

The Allemanskraal Dam is a dam in the Free State province of South Africa, on the Sand River. It was established in 1960. The reservoir has a gross capacity of 174,500 cubic metres (6,160,000 cu ft), and a surface area of 26.481 square kilometres (10.224 sq mi), the dam wall is 38 metres (125 ft) high.

The Sand River is a river in the Free State, South Africa. It is located close to Welkom and Virginia in the gold mining center of the Free State. Its source is located close to Tweefontein NW of Ficksburg not far from the South Africa/Lesotho border, at 28°40′49″S27°41′23″E. This river is famous because of the historical Sand River Convention, an important event in South African history.

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.

Boundaries
