Authorities have issued an updated alert for communities living near the Bronkhorstspruit River as structural concerns at Thabos Dam intensify.

Operational teams are currently cutting channels into the embankment to relieve pressure on the dam wall, while additional machinery is being deployed to increase water outflow.

Residents in low-lying areas from Schietpoort Farms through Hondrivier, Bronkhorstspruit and towards the Cullinan Premier Mine Dam are urged to remain vigilant and be prepared to move to higher ground if instructed.

According to the City of Tshwane progress on-site is slow but steady, and teams are making measurable headway despite challenging conditions.

“The community is requested to remain on high alert. All previous safety precautions issued by the City of Tshwane Emergency Services remain in full effect. Residents—especially those in low-lying areas—are urged to continue monitoring official updates and be prepared to move to higher ground if instructed.”

This comes as Gauteng is expected to see cloudy conditions with a good chance of thunderstorms and showers over the next few days. Temperatures will generally range from the low-20s°C by day and mid-teens°C at night, with showers and storm activity likely Saturday and Sunday. This reflects the unsettled summer weather pattern typical for the region this season.
