Lake Superior water levels drop after hot, dry summer

Hot summer weather and drier than average conditions have led to a lowering of Lake Superior water levels. The International Lake Superior Board of Control (ILSBC) said water levels had declined and reached the seasonal long-term average for the first time since April 2014. In its September update, the ILSBC said Lake Superior declined three centimetres in the month of August, a month that normally see the lake rising one centimetre.
