There are a number of Elands Rivers in South Africa. This article refers to the one in Mpumalanga.
The Elands River flows from near Machadodorp to just below the Montrose Falls. It is part of the Komati River basin.
The river flows past the town of Waterval Boven then plummets 70 metres over the Elands River Falls, before flowing past the town of Waterval Onder.
The Elands River joins the Crocodile River just below the Montrose Falls. This is near the intersection of the N4 and R539 roads.
