The DWS said the dam started to show signs of recovery after water levels declined drastically over the past few months.
The dam plummeted to below 39% after a series of heatwaves and dry conditions in the province and now stood at 40%.
“Gauteng leads with a significant increase to 111.3%, compared to 88.2% last week. This is within the context that Gauteng dams are significantly smaller than those in the Northern Cape and Free State in terms of volume,” the department said.
