It has rained, it has poured and it has even stormed almost apocalyptically, but the back of the country's ongoing drought is yet to be broken.

With one tweet, the department of water and sanitation's deputy director general for emergency services, Trevor Balzer, put everything into perspective.

"The drought is not over," he wrote on Saturday.

His reason for saying this is that the Free State's Vaal Dam, arguably the most important in the country because it supplies the majority of Gauteng's water, was at just 32.9% by 6am that morning.

While this is an increase from the 26.3% level exactly two weeks ago, it is still significantly lower than this time last year, when it was 53.6% full.

  • Floods: Search for missing girl called off‚ for nowThe search for a missing three-year-old‚ swept away during flash floods in Johannesburg on Wednesday evening has been called off for the day.

In fact, dam levels are down in every province compared to a year ago, despite the downpours. Only the North West is up, while Gauteng is the same as it was last year.

In KwaZulu-Natal, where restrictions have been in place since February last year, the situation is still dire. Midmar Dam, which supplies Pietermaritzburg and most of Durban, is at 50%.

"This is an increase of 2% over the past week, an increase that is attributed to run-off into the dam, weekend rainfall in the catchment of about 30mm and transfer of water into it from Spring Grove Dam," said Umgeni Water's Shami Harichunder.

  • Flash flooding was once-in-a-100-year occurrenceThe storm water systems were overwhelmed by the severe rainfall that struck Johannesburg on Wednesday‚ the South African National Roads Agency acknowledged today. However‚ the flash flooding is unlikely to reoccur soon.

"The current level of Midmar Dam is about 5% lower compared to the same period a year ago. Midmar Dam must reach a level of at least 70% before the situation could be considered normal."

The problem in KwaZulu-Natal and Gauteng, is that rains fell in the wrong areas.

"Much of the torrential rains fell outside of the catchments. Rains in urban areas generally make their way into drainage systems and, ultimately, the sea," said Harichunder.
