Heavy rains this week caused havoc across parts of the North West and Gauteng, various organisations and government bodies said on Wednesday.
The Greater Taung Local Municipality said its areas was declared a disaster zone after one person drowned and about 150 households were left destitute after flooding in its area.
Municipal spokeswoman Gontle Metswi said about 150 households had been affected by flooding but exact numbers were still being collated.
Roads leading to areas such as Manokwane, Lokaleng, Khibitswane, Mokgareng and Pudimoe had also become flooded.
People were warned to stay away from water and bridges and drive carefully in wet weather.
Meanwhile, about 800 mine workers were evacuated from East Rand Mines' operations.

Aurora Empowerment Systems CEO Zondwa Mandela -who is also the grandson of Nelson Mandela - said the measure had been undertaken in the interests of ensuring the mineworkers' safety at all times.
Two shafts at the mine had been flooded.
Above average water levels had seen the mine pumping 120 million litres of water per day instead of 80 million.
Despite these efforts water seepage had remained at unsafe levels resulting in Aurora ordering the evacuation of the operations.
Water Affairs spokesman Mava Scott issued a warning on Wednesday that people living along the Vaal Orange River system should stay away from rivers as sluice gates were opened to relieve pressure on bulging dams.
With the Vaal dam 105 percent full due to heavy rains, both the police and Rand Water warned the public of the potential for flooding.
Water gushed along the river system into the Vaal Barrage Reservoir which runs through Vanderbijlpark and Vereeniging.
The heavy rain also affected the Bloemhof Dam in North West which is currently 112 percent full.
Flood gates were opened there on Wednesday with heavy water flows expected downstream.

Torrential rains and floods in the North West and Gauteng provinces of South Africa have caused disruption, government bodies said earlier today.

The Greater Taung Local Municipality said a disaster area was declared, after 150 homes were affected and one person was confirmed dead from flooding.

Residents were warned to keep away from bridges and rivers, and to drive carefully in the inclement weather. Water Affairs spokesperson Mava Scott commented that "people in the low lying areas should be alerted."

The Vaal Dam, meanwhile, was at 105% full, after six sluice gates were opened. Three more are expected to be opened soon, according to the South African Press Association. The Bloemhof Dam in North West province is 112% full, with flood gates having been opened there earlier today.

Officials encouraged people to remove their boats and pumps, as water flow would not be predictable. "It will also be rather dangerous for people to go too near to the river's embankments during this time," Superintendent Eugene Opperman noted.

Meanwhile, roads to places such as Manokwane, Lokaleng, Khibitswane, Mokgareng, and Pudimoe, were also inundated with water. 800 mine workers from East Rand Mines were evacuated as well.
