It rises near
Lichtenburg on the far southwestern slopes of the
Witwatersrand and flows for 320 km (about 200 miles) in a southwesterly direction, mostly through very flat areas of the North West and Northern Cape Provinces before flowing into the Vaal River about 100 km above the confluence of that river with the Orange River. The
Little Harts River which rises near
Coligny joins the
Great Harts River, which rises near Lichtenburg, to form the main river. Near Taung, the
Dry Harts River, a seasonal river with its headwaters in the
Vryburg area, also joins it. The river is characterised by highly intermittent runoff, but is regulated to optimise water usage. At
Taung the
Tswana referred to the Harts River as the Noka (meaning River) Kolong. Further downstream, the town of
Schweizer-Reneke (founded in October 1888) lies on the banks of the river.
Wenzel Dam, just north of the town on the river, has been developed into a holiday resort. Around 1850, a dam was built in the river next to
Dikgatlong, but it was washed away during a flood in 1856. Near the confluence of the Harts and Vaal Rivers at
Delportshoop a major irrigation system, the
Vaal-Harts Scheme was set up in 1933 as part of the national reconstruction effort after the
Depression. Here water drawn from both the Vaal and the Harts rivers provide water to intensively irrigate numerous
smallholdings through a system of canals in an otherwise dry area of the country, supporting towns such as
Jan Kempdorp and
Hartswater. Around the northern part of the Scheme lie the settlements of
Pampierstad,
Motsweding,
Mokgareng,
Manthestad and
Taung, all with mostly
Tswana speaking residents. Taung became famous after the discovery of the skull of the so-called
Taung Child in a lime quarry 14 km west of the town. The quarry is not in use anymore and is now the
Taung Heritage Site and open to the public. To the west of the town, the
Taung Dam was built in the Harts River. Upstream of the dam some rock engravings can be seen. ==History==
