Jozini: The Department of Water and Sanitation (DWS) says it is preparing for the imminent release of water from the Pongolapoort Dam in Jozini, northern KwaZulu-Natal. This follows weeks of heavy rainfall that have caused several dams in the region to exceed their capacity.
According to South African Government News Agency, the Pongolapoort Dam has reached 97.97% of its capacity due to continuous inflows from the upstream Upper Pongola River Catchment. The releases are part of standard operational rules and dam safety protocols to maintain safety and prevent potential risks associated with overcapacity. The department emphasized that water release is necessary to ensure the structural integrity of the dam and safeguard surrounding communities from the dangers of dam failure. If the current inflows persist, the dam is expected to spill over the uncontrolled spillway by Wednesday, 16 April 2025.
The department noted that inflows are unpredictable and subject to change, which could result in an earlier or delayed uncontrolled water release. Currently, the inflow exceeds the outflow, causing the dam level to rise steadily. As a precaution, communities have been notified of the imminent release to ensure preparedness and safety.
The increased outflow into the Pongola River will raise water levels, potentially affecting low-lying areas, floodplains, low-level bridges, and agricultural activities. Residents downstream are advised to remain vigilant, as the release may lead to localized flooding. Communities in and around Jozini and Makhathini Flats, including Welcome, Hlazane, Mboza, KwaShukela, Mzinyeni, Skhemelele, KwaLulwane, Bhekabantu, Mamfene, Shemula, Hlokohloko, Madonela, and Ndumo, are urged to exercise extreme caution during and after the water release.
Engagements with the Lower Pongola Water User Association, representing water users and communities along the river, are ongoing to keep stakeholders informed regarding the department’s emergency preparedness plan. The department reiterated that the Pongolapoort Dam remains vital for water management and flood control, and it will continue to monitor the dam’s performance and inflow rates to ensure safe and efficient operation.
This proactive approach underscores the importance of balancing water storage with safety, ensuring the well-being of communities and the environment while maintaining the dam’s functionality. The DWS follows established operating rules and procedures for water releases necessitated by floods and will implement them in coordination with the National Disaster Management Centre, Provincial Disaster Management Centres, and affected local municipalities.
