For years the Vaal River, has been choked with tons of sewage, heavy metals and toxic waste. But the recent flooding is flushing the river, washing away polluted sediment and has given the ailing water way a new lease of life.
Once there is no rain in the catchment area the flow will be stemmed by closing a number of gates.

"A lot of fish have moved into areas where the water is slower moving, if the drop in the river is to quick then these fish would be left stranded"
