Vaal Dam: Good news as water levels enjoy a magnificent surge
Gauteng’s biggest water source has been enduring a torrid time of things lately. Situated in the south of the province, the Vaal Dam has taken a worrying tumble in 2019. Light water restrictions remain in place for the region, and the facility even dipped below 40% full in December. But there is light at the end of the tunnel.
Mon 16 Dec. Vaal Dam Level 16.78m. Full 44.08%. Inflow 484.12m3/s. Discharge 16.77m3/s. River Valves Open 1×100%; 1×50%. Gates Open 0.

Gauteng: Latest water levels for the Vaal Dam on Monday 16 December
Figures released on Monday morning show that the inflow of water to the Vaal Dam has towered above its output. For the first time in months, the reserve has enjoyed positive weekly growth. It’s now 44.08% full, and the figures are a little easier on the eye than they have been in December.
Since last Tuesday, the water levels have been on a slow and steady rise. A 5% increase over the past seven days is truly a magnificent achievement. The biggest rise in a single day came over the weekend, as the volume of water shot up by 1.25% in a 24-hour period. Here is the Vaal Dam’s weekly performance:
- Tuesday 10 December: 39.05%
- Wednesday 11 December: 39.37%
- Thursday 12 December: 40%
- Friday 13 December: 41.03%
- Saturday 14 December: 41.77%
- Sunday 15 December: 43.02%
- Monday 16 December: 44.08%
What has made the difference?
It is believed that the heavy storms which hit the north of Gauteng last week are finally having an impact down south, as the deluge passes through the river networks. We saw earlier last week how Hartbeespoort Dam was overflowing, as it is situated just outside of Centurion. Although the Vaal Dam has a long way to go to match this performance, every drop counts – and locals will welcome all the good news that comes their way.
