Vaal Barrage

The current inflow is 110.6 cubic metres per second (m³/s), while the outflow is measured at 16.8m³/s.

The Vaal Barrage, a vital infrastructure downstream of the Vaal Dam, also reported significant activity.

Barrage levels stand at 7.5 metres, with an outflow of 15.1m³/s. The water temperature has reached 23.2°C, highlighting the ongoing seasonal changes.

“The inflows continue to sustain the dam, and outflows are being managed accordingly,” said a water management official.

“We are closely monitoring the situation to ensure stability in the system.”

Authorities continue to monitor the dam, which is essential for supplying water to Gauteng and surrounding regions.

Residents and businesses relying on the Vaal River system are urged to remain mindful of water consumption.

Meanwhile, the Grootdraai Dam decreased from 105.17% last week to 102.5% capacity this week.

Recent data shows the dam’s inflow at 85m³/s and outflows, primarily due to overflow, at 46m³/s.

No gates have been opened, indicating that water levels are being efficiently regulated.

According to the South African Weather Services’ (Saws) alerts for the past weekend, the Mpumalanga province had a 30% probability of isolated showers.
