Blesbokspruit

Blesbokspruit is a river that originates north of Daveyton, Gauteng, South Africa. It runs south and later west, past the towns of Springs, Nigel and Heidelberg, before it joins the Suikerbosrand River, a tributary of the Vaal River. The Marievale Bird Sanctuary is situated in its upper reaches, established when the roads and pipelines reached the nearby mines in 1930. That area of 1848 ha was declared a Ramsar site wetland in 1986, to combat deleterious effects of industrial pollution in the area.
