Vaal’s water levels continue to rise, five sluice gates to remain open
As the water levels of the Vaal dam continue to rise, the Department of Water and Sanitation (DWS) will keep all the five sluice gates open, with no changes in the dam’s outflow of 760 cubic metres per second (mᵌ/s).
The DWS opened the fifth sluice gate on Sunday morning, less than 24 hours after opening the fourth sluice gate on Saturday, owing to the heavy inflows into the Vaal dam.
The Vaal dam’s water storage levels increased from 107.82% to 109.39% overnight by Sunday, and increased again to 111.11% by Monday morning, amid the continuous high inflow of water at 1 002.25 mᵌ/s from the upper catchment.
Should there be increased inflows into Vaal dam, additional gates may be opened.
The DWS will continue to monitor Vaal dam and effect changes on the outflow as and when necessary.
Bloemhof dam's storage level have also increased from 107% on Sunday to 112.08% full supply capacity by Monday morning.
As a result, water releases will be staggered incrementally in two-hour blocks, starting from 1 400 m3/s to 1 850 m³/s by 16:00 on Monday.
At Grootdraai dam, upstream of the Vaal dam, one sluice gate remains open to enable water releases. The dam’s water storage levels are at 102% full supply capacity.
