The Elsieskraal River (AfrikaansElsieskraalrivier) is a small river that flows through the Cape Town metropolitan area, in South Africa. It rises in the Tygerberg Hills and flows in a generally south westerly direction to its confluence with the Black River just south of Pinelands. 65% of the course of the Elsieskraal River has been canalised to prevent flooding.[1] Its catchment is part of the Central Management Area of the City of Cape Town.[2] As most of the catchment area is urbanised and the river receives rapid runoff from roads, roofs and other impermeable surfaces it is prone to rapid increases in discharge after rain.
