In reference to the article, “Global warming hits Midmar Dam”, in Weekend Witness on July 19, Umgeni Water wishes to respond to the contents. There is currently no major change being seen in the behaviour of the water temperature in the Midmar impoundment. On the contrary, median annual temperatures have cooled slightly in recent years. Winter minimum temperatures have behaved similarly. While climate change is a concern and is receiving attention at Umgeni Water, it is the possibility of droughts and floods that are by far the most important problems needing attention.
