JOHANNESBURG - Government is warning of possible flooding in the Vaal.
It follows heavy rainfall and high dam levels.
Over the weekend, floodgates at various dams had to be opened as they were overflowing.
The Water and Sanitation Department is urging residents to be vigilant.
"We've retained those sluice gates at the Vaal because the inflows are still quite high and therefore the issue of what happens downstream remains a concern," said spokesperson Sputnik Ratau.
"That is why it is important that all of us need to be aware, especially those communities that are downstream at the Vaal that will be affected by the rise of the river."
