The Rietvlei dam is an earth-fill type dam and is one of a number of dams supplying water to the Pretoria region of South Africa. It supplies around 41 million liters of drinking water daily,[1] about 5.9% of the water requirement of Pretoria.[4] The dam mainly serves for municipal and industrial use. Its hazard potential has been ranked high (3).

Constructed as an earth-fill dam wall with a brick core in 1932/4, it was extended between 1988 and 1990 by raising the dam wall with the addition of a concrete wave wall and a reinforced earth barrier wall, as well as a surfaced roadway, on top of the original wall.

The dam is fed by the Rietvlei, a river of the Crocodile River (Limpopo) basin, as well as by five fountains and five boreholes.

The Rietvlei Nature Reserve occupies the area immediately surrounding the dam.
