The largest rivers in South Africa are Orange and Limpopo. In total, the territory of the republic is crossed by about one hundred and twenty rivers and rivulets, of which about one hundred constantly dry up.
Caledon River
The river channel "captures" the territories of neighboring countries - South Africa and Lesotho. It is the channel of the Caledon that will play the role of a natural border dividing the lands of these states.
The source of the Caledon is located in the Drakensberg Mountains. The total length of the waterway is four hundred and eighty kilometers. She completes her journey, connecting to the waters of the Orange River.
Black Cay River
The river bed is wholly owned by South Africa and runs through the lands of the Eastern Cape. The origins of Black Cay are located on the slopes of Stormberg (southwest direction from the town of Queenstau). The river ends its journey across the country, connecting with the waters of Big Cay. The main tributaries are the Klimplat and Klaas Smits.
Near Cathcart, Black Cay merges with another river, White Cay, to form another waterway in the country known as the Great Cay River. The Black Cay channel delineates the western borders of Tsolwana, a large nature reserve in South Africa.
Great Cay River
Great Cay is one of the South African rivers flowing through the lands of South Africa. Its total length is five hundred and twenty kilometers with a total catchment volume of twenty thousand squares.
The source of the river is formed by the confluence of two rivers - Black Cay and White Cay. The beginning of Great Cay is located near the village of Cathcart. The river ends the way, dumping its waters into the waters of the Indian Ocean. The river has several tributaries of its own.
Vaal river
Vaal is included in the list of the longest waterways crossing the territory of southern Africa, with a length of one thousand two hundred and fifty kilometers. The total catchment area of the Vaal Basin is slightly more than one hundred and ninety-six thousand squares. At the same time, the Vaal is the longest tributary of the Orange River.
The Drakensberg Mountains became the beginning of the river. Then Vaal descends and "moves" across the country, choosing a western direction. And at the end of the path it connects with the Orange River near the town of Kimberley. The upper course of the Vaal runs through the Drakensberg Mountains and the High Veld Plateau. This river section is located at the bottom of a deep valley. The river has its own powerful tributaries, in particular, the Rit, Vilge, Fet and others.
The river becomes especially full-flowing in the period from November to February (these are the summer months of the year). The Vaal is blocked by several dams that form voluminous reservoirs.
Vaal plays an important role in the life of the entire South Africa. It is its waters that are used to meet the industrial needs of the capital of the country - Greater Johannesburg, as well as the cities of the Free State province.
