Dam levels in the South-Western Cape showed a huge jump over the past week after two cold fronts hit the province.
On Thursday there is another 30% chance of more rain over large parts of the Western Cape.
The province’s average dam level was 44.4% on Monday, compared to 41.2% a week ago. Last year it was at 39.4%.
Cape Town’s average dam level has increased from 58.5% to 62.6% over the past week, compared to 52.6% this time in 2019.
Sputnik Ratau, spokesman for the Department of Water and Sanitation, said in a statement that the heavy rain provided much-needed water to the Western Cape’s dams.
Some dams such as Eikenhof Dam, Lakenvalleidam and Stettynskloof Dam have risen by more than five percentage points over the past week.
Ratau says the department hopes good rains continue and that dam levels continue to rise.
“The 2019 -20 winter rainfall season is better than that of 2016 to 2018. This period was characterized by ongoing drought which resulted in the province’s average dam level falling to as low as 17% in April 2018.”
The level of Theewaterskloof Dam, the largest storage dam in the province, has risen from 55.4% to 59.3% over the past week compared to 44.5% a year ago.
The levels of other dams that provide water to Cape Town look like this:
• Lower Steenbras Dam: 49.3% (48.1% last week) with 25.5 mm of rain in the previous seven days
• Bo-Steenbrasdam: 100,7% (99,6%)

In the north-west of the province, Clanwilliam Dam’s level rose from 18% to 19.9%, compared to 16.4% in the corresponding period last year.
In the Karoo , most dam levels have dropped slightly and many dam levels remain extremely low:
