The latest information reveals the severity of the situation, with the Vaal Dam reaching 121.53% capacity as of Monday.
Residents in areas along the Vaal River are refusing evacuation orders despite dangerous flooding conditions, according to reports from the National Sea Rescue Institute (NSRI).
This resistance comes as authorities have opened ten sluice gates at the Vaal Dam on Friday.
Water and Sanitation Deputy Minister David Mahlobo expressed frustration at this situation, noting: “We’ve been working so hard with many communities, and there’s been a lot of positive response working with the NSRI, the police, the disaster management centers in the municipalities.
“But there are those communities that have been ignoring our request,” Mahlobo told eNCA.
Vaal Dam water levels reach critical point
The latest Vaal Dam and Vaal Barrage Hydrological Information reveals the severity of the situation, with the dam reaching 121.53% capacity by Sunday, maintaining those level through Monday.
The dam is currently experiencing an inflow of 1832.0m³/s and an outflow of 1881.0m³/s.
This represents a dramatic increase of 2.21% since Friday, when the Department of Water and Sanitation opened the tenth sluice gate as the dam’s water levels reached 118.48%.
Prior to this action, the water levels had increased by approximately 6.36 percentage points in a single 24-hour period, driven by heavy rainfall throughout the region.

Residents slam authorities over Vaal Dam water management
Communities along the Vaal River have expressed anger toward authorities, claiming that water levels could have been better managed to avoid the current flooding situation.
Some residents have gone so far as to describe the decision to open additional sluice gates as “disastrous.”

Despite these criticisms, officials defended their approach to the crisis.
Mahlobo detailed the government’s escalating response, saying, “Minister and myself, we visited on 9 April. We went to the Vaal’s system. As we are correctly saying today, we have opened 10.”

Massive water release operations underway
According to the latest Vaal Dam and Vaal Barrage Hydrological Information, Bloemhof Dam started releasing 3,600 m3/s at 9am on Monday.
The scale of the water management challenge is significant, as Mahlobo explained.
“We are actually even releasing more than 1.8 billion liters per second. And because there are many other rivers in Uveka just in between the valley dam system and the Vaal barrage and the Bloemhof Dam,” the deputy minster said.
“And the Bloemhof, the water is at the highest level, more than 3,600 billion liters that are coming in per second and who are also releasing and serving sluice gates,” he added.
At the Vaal Barrage, water levels have reached 6.0m with an outflow of 2116.0m³/s and a water temperature of 18.5°C, according to Sunday’s hydrological information.

Coordinated response efforts continue
Despite resistance from some residents, Mahlobo emphasised the positive coordination between various agencies.
“We have to convey our sincere gratitude to all those communities from here in Houghton, the Northwest, the Free State, and the Northern Cape that have responded to the call by Minister Pemmy Majodina in early April.”
As water levels continue to rise, authorities remain focused on convincing reluctant residents to evacuate while managing the unprecedented water volumes flowing through the Vaal Dam system.
