Rietvlei River

The Rietvlei River is a small river in central Gauteng Province, South Africa. It feeds the wetlands of the Rietvlei Nature Reserve, before it flows into Rietvlei Dam, which is one of the main sources of water for Pretoria. The river downstream of the dam is known as Sesmylspruit, which is a tributary of the Hennops River and part of the Crocodile River (Limpopo) basin.
