Johannesburg - Four more Vaal Dam sluice gates were opened on Thursday afternoon following an increase in the water inflow into the dam, Emfuleni Local Municipality said.

"This brings the number of opened gates to 17 since December 16," spokesperson Klaas Mofomme said in a statement.

He said the municipality would like to warn community members to continue being on high alert for possible flooding.

"However, it must be emphasised that our joint operation committee team, which includes the emergency services and disaster management teams, is on high alert to provide the necessary services should the need arise."

Mofomme said the outflow into the Vaal River was now standing at 2.7 million litres per second and the water outflow is about 90 times higher than the normal flow.

All boat owners were advised to remove their boats from the water even if they were in boathouses on the river.

"We also appeal to residents around the lower situated establishments not to panic but to be on high alert."

Community members were advised to report any incident to the Sedibeng call centre on 10177.

Flood warnings

The call for caution came after the Emfuleni municipality and the Mpumalanga province issued flood warnings on Thursday after main rivers began overflowing.

Heavy rains resulted in overflowing on the Vaal Rriver in Emfuleni, the Gariep, Bloemhof and Vanderkloof dams, as well as the Crocodile (Mgwenya) River in Mpumalanga.

"The water levels downstream of Vaal Dam are expected to reach levels last seen during the flood of 1996," water affairs spokesperson Linda Page said.

Page said the capacity of the Bloemhof dam was currently 98% with the outflow expected to increase substantially through Thursday to 2 800m³ per second by 18:00.

The Gariep dam capacity was 113% while the Vanderkloof dam was at 107%.

The outflow was due to increase considerably by Sunday.

Roads closed

The flow in the Lower Orange River was around 5 200m³ per second.

A number of roads around Three Rivers in Vereeniging were closed due to the flooding.

These included Brandmuller, Golf, Klip River, and General Hertzog roads.

Houtkop road, commonly known as Potchestroom/Vereeniging road, was the only one accessible.

The municipality urged residents to avoid the affected areas.

"Motorists are advised not to underestimate the strength of the water in the flooded areas, but rather take alternative routes," said Mofomme.

Mpumalanga

Residents living along the Crocodile River in Mpumalanga were also urged to stay alert as the river flow had increased.

Provincial co-operative governance spokesperson Simphiwe Kunene said the communities of Kanyamazane, Matsulu and Nkomazi must be on full alert.

"The Kwena Dam that feeds the Crocodile River is more than 105% full and already overflowing into the river."

He said it had increased the already high river flow.

Those living downstream near the Elands River were also warned.

"The continued rains have resulted in an increase of dam and river levels thus making small streams very dangerous," said Kunene.

"Parents are urged to warn children not to play next to streams and rivers."

Weather patterns indicate that rains will continue for the next few days.

    Why were these sluice gates not opened much sooner to minimise the water level damage downstream?? Is this yet another classic example of PDI [ Presently Dysfunctional Incumbents ]disaster mismanagement??? Rainfall records will clearly show that, based on the past four years at least, this situation should have been anticipated and re-acted to accordingly.

      Go listen to the audio track at http://www.timeslive.co.za/local/article836833.ece/Vaal-River-flood-warning-issued then you can make form a better opinion. Of course, no compensation will be offered, I bet these "managers" are all living somewhere high-and-dry. They should be forced to live on the river they manage, maybe then they'll make decisions differently.

      How can we save the excess water if no plans are in place for additional dams, pipelines to empty dams and underground storages. Lack of forward planning the past 15-16 years.
