Vaal River residents urged to evacuate as water levels surge beyond capacity

Vaal River residents urged to evacuate as water levels surge beyond capacity! Persistent rainfall across several regions in South Africa has pushed the Vaal Dam beyond its storage capacity, forcing the Department of Water and Sanitation to open additional sluice gates and urge residents along the Vaal River catchment to evacuate as a safety precaution.

The department announced over the weekend that sluice gates four and five had to be opened after water storage levels at the dam exceeded 100% capacity, raising concerns of downstream flooding. As the gates released large volumes of water into the Vaal River, communities along the riverbanks were placed on high alert.

Controlled Releases to Prevent Infrastructure Collapse

Wisane Mavasa, the department’s spokesperson, explained that the controlled releases are part of a safety protocol to protect the structural integrity of the dam.

“The department is currently implementing the necessary controlled releases at the dams as part of the dam safety precautions to safeguard the infrastructure,” Mavasa said in a statement.

Opening the sluice gates is considered a preventive measure aimed at avoiding an uncontrolled overflow, which could pose greater danger to both the dam structure and communities living downstream.

Low-Lying Areas at Risk

The department has warned that low-lying areas and riverbanks downstream of the dam are at particular risk due to the increased water flow. These areas may experience localized flooding, which could damage homes, roads, and other infrastructure.

In light of the risk, residents living close to the river have been urged to begin evacuating immediately, especially those in vulnerable and low-lying zones. The department advised people to move valuable equipment, movable infrastructure, and livestock to higher ground in order to prevent damage or loss.

“This is a precautionary measure meant to save lives and property,” Mavasa added.

Emergency Preparedness and Community Cooperation

Local disaster management teams have been placed on standby, and municipalities are coordinating efforts to assist communities in the affected areas. Emergency services have also been activated to respond quickly in case of flash flooding or other incidents resulting from the high water levels.

Residents are being encouraged to remain vigilant and to follow weather updates closely, as the situation could change rapidly depending on ongoing rainfall.

“We are closely monitoring the situation and will adjust the water release volumes based on weather forecasts and inflows into the dam,” Mavasa explained. “If rainfall decreases in the coming days, we may be able to reduce the gate openings.”

Widespread Rainfall Straining Water Infrastructure

The surge in water levels comes as parts of Gauteng, the Free State, and North West provinces experience persistent and heavy rainfall over the past few weeks. While the rain has brought some relief in terms of water supply, it has also placed a considerable strain on the country’s dam infrastructure and flood management systems.

In response, the Department of Water and Sanitation is working with the South African Weather Service (SAWS) to closely monitor rainfall patterns and predict inflows into major dams.

Residents and farmers near the river are urged to remain in contact with local authorities, and anyone observing signs of rising water or infrastructure instability is encouraged to report it immediately to municipal emergency services.

The Way Forward

Although the department has implemented controlled measures, officials acknowledge that the situation is fluid and could escalate. For now, the focus remains on public safety, infrastructure protection, and maintaining clear lines of communication with affected communities.

With rainfall still forecast for the coming days, authorities are urging residents not to take unnecessary risks. “We appeal to everyone to cooperate during this time,” Mavasa said. “Your safety is our priority.”
