Rietvlei Nature Reserve
Rietvlei (Reed marsh) has a size of 38 square kilometers and covered by 91km of roads. 40 km of these roads are open to the public (30km tarred and 10km dirt road) for self drive game viewing. The Rietvlei and Marais dams are located inside the reserve.
The reserve consist of three main areas:
The only boats allowed on the dams are those operated from the Yacht Club. Powerboats are totally forbidden as the noise disturbs the wildlife.
The reserve is generally not very busy. You will often have a bird hide all to yourself and there is seldom anyone else around to make noise and scare away the wildlife.
Summer is excellent for bird watching as many of the migrating species will also be found in the reserve, but the long lush grass may obscure some of the other wildlife. Rhino may be especially difficult to spot. Some antelope species will still be easily visible due to their size and the fact that they graze along the hill sides.
The Rietvlei dam supplied about 5% of Tshwane's water supply.

The government bought Rietvlei on 2 Sept 1929 as Rietvallei (Extent 1 ), from DM Munro, in order to build the Rietvlei dam. As part of the Rietvlei water scheme, the Rietvlei dam was built in 1934 on the Six Mile Spruit. The dam wall is an earth structure and was built completely by hand. Donkey carts were used to cart soil onto site and remove any soil and other material that was no longer required. Many horse shoes lost by these working donkeys can still be found in the hill behind the Yacht Club.
In 1948 the city of Pretoria, which owns the land, proclaimed the area a nature reserve.
Mostly open grassland covering low hills with indigenous tree in small groups. Rare for South Africa, it also contains a peat wetland area. An ancient lava stream runs north/south through the park.
The dams are fed by the Six Mile Spruit and four fountains on the reserve as well as one from an adjacent property.
