Global climate change could be causing staggeringly low water levels on Lake Superior, but normal variations in weather could also be behind the drop, say officials charged with monitoring lake levels.
Either way, weather is the reason for this year's unprecedented decline and it's going to take long periods of above-average precipitation to get things back to normal, insists David Fay, Canadian member of the International Lake Superior Board of Control.
|Low water levels are visible at Point Des Chenes, northwest of the Sault, where Lake Superior has receded far from the beach this year.
Shallow docks have been left high and dry this year and swimmers have been forced to walk further to get wet, as Lake Superior dropped to 53 centimetres below normal for the beginning of June and 40 centimetres below last year's level. That's just 10 centimetres higher than the record low, recorded in 1926.
