Dept of water affairs urges caution in the vicinity of the Vaal Orange River System

The water levels of the four largest dams in the Orange River catchment were rising following heavy rains in the past day, the department of water affairs said on Tuesday.

The Vaal Dam was 103% full and three sluice gates were open, spokeswoman Linda Page said in a statement.

It had an outflow of 870 cubic metres per second.

In the Free State the capacity of the Bloemhof Dam was currently at 104% with an outflow of 1000 cubic metres per second.

The Gariep Dam, the largest dam in South Africa, was at 107 percent with an outflow of 1670 cubic metres per second which would increase to about 2900 cubic metres per second, Page said.

The capacity of the second largest dam, the Vanderkloof Dam, was at 107.7% with an outflow of 1323 cubic metres per second and would increase to about 2500 cubic metres per second.

As more rain was forecast over the next 24 hours, it was expected that changes to outflows would be made, she said.

“The department of water affairs wishes to again urge all communities to exercise caution in the vicinity of the Vaal Orange River System and affected dams,”
