The study area includes the whole of the Crocodile West River catchment as shown in the figure below. It also includes part of the Upper Vaal River system which supplies part of the Crocodile River catchment south of the Magaliesberg, Gauteng North, by Rand Water and the Mokolo River catchment, where water supplies to the large mining, power generation and petrochemical developments in the Lephalale area need to be augmented from or via the Crocodile West River catchment.


Crocodile West Reconciliation Strategy Study Area

The Crocodile West River is the largest and most important river in the Crocodile West and Marico Water Management Area. The catchment extends northwards from the Witwatersrand catchment divide in central Johannesburg (where the Crocodile River originates) to the confluence of the Crocodile and Marico rivers. From the confluence of the Crocodile and Marico rivers the river is known as the Limpopo River, which forms the northern border of South Africa with Botswana and then with Zimbabwe, before flowing into Mozambique where it discharges into the Indian Ocean. The Limpopo River basin thus is an international basin shared by South Africa, Botswana, Zimbabwe and Mozambique. In South Africa the Crocodile West River is characterised by the sprawling urban and industrial areas of northern Johannesburg and Pretoria, extensive irrigation downstream of Hartbeespoort Dam and large mining developments north of the Magaliesberg. As a result, the Crocodile River is one of the rivers in the country that has been most influenced by human activities, and specific management strategies are of paramount importance.
