It lies in a valley to the south of the Magaliesberg mountain range and north of the Witwatersberg mountain range, about 35 kilometres west of Pretoria. The name of the dam means “pass of the hartbees” (a species of antelope) in Afrikaans.
The town of Hartbeespoort is situated close to the dam wall and the villages of Kosmos, Melodie, Ifafi and Meerhof can be found alongside its banks. Hartbeespoort was previously known as Schoemansville. Hartbeespoort has become a very popular holiday and weekend resort for the inhabitants of Johannesburg and Pretoria; it is the principal water recreation area of northern Gauteng
and many types of water sports are practised on the dam. The Transvaal Yacht Club has been operating at the dam since its construction in 1923
The dam wall is 149.5 metres (490 ft) long and 59.4 metres (195 ft) high and is built across a gorge cutting through the Magaliesburg. The reservoir is fed by the waters of the Crocodile River and Magalies River and covers approximately 18.83 square kilometres (7.27 sq mi).
