VAAL TRIANGLE - The Department of Water and Sanitation has on Wednesday announced that one sluice gate will be closed at the Vaal Dam. Spokesperson Sputnik Ratau says this was due to the continuous decrease that’s been seen in recent days. Ratau said one sluice gate would be closed yesterday afternoon leaving the four gates open to further reduce capacity to a safe level. The department decided to open five sluice gates in early January after the dam reached over 110% capacity. He said the dam – which supplies most of Gauteng - now stands at 103,5% full and the levels continue to decrease. He adds that the department will continue to monitor the inflows. Ratau said further decisions will be made on when the other sluice gates will close. We will continue to monitor the Vaal-Orange River System and the Integrated Vaal River System. Outflow will be kept at a manageable rate to reduce capacity to a safe level.
