== Loskop Dam == 
 I see in the edit remarks that you say Loskop is only a reservoir and not a dam wall, i can tell you it is both, go to http://www.dwa.gov.za/Hydrology/applets/weekly/WeekIndex.html    than  Mpumalanga Province then Loskop Dam  and tick on the p behind the name of the river it will show you a picture of the actual dam wall.
