Edit: The current 75% Vaal Dam level is not a cause for alarm IMO. By contrast, this thread from 2016-17 shows a real crisis, when levels were below 30%: https://mybroadband.co.za/forum/threads/vaal-dam-levels.837685/post-18653673
Those levels were in August, meaning after the winter. What is the average levels in January?
