[1] The Nwanedi river collects part of the drainage of the northern slopes of the extensive rock formation of the Soutpansberg.

The upper Nwanedi is a perennial stream with twin dams where it is met by its tributary, the Luphephe River, in a wooded area of the range.

This lower part is subject to seasonal fluctuations, being mostly dry during periods of drought, with a few disconnected ponds in the riverbed.

[5] The Nwanedi Provincial Park is located about 35 km north of Thohoyandou, in a wooded area on the foothills of the Soutpansberg.

The protected area includes the confluence of the Nwanedi and its main tributary, the Luphephe River, where the dams are.
