Beyond the visible problems created by low water levels in the Great Lakes, including difficulties for marina operators and boaters, one very important issue might not be as evident – electricity generation.
From Midwest Energy News:
“Michigan’s knew it had a problem last year. Output at its hydroelectric plant at Sault Sainte Marie kept dropping dramatically before bouncing back up.‘We experienced about a 60-80 percent drop in the plant’s output,’ says Phil Schmitigal, Cloverland’s Director of Generation.
Lower levels in Lake Superior reduced the canal’s water allocation from the International Joint Commission. The lower lake levels also reduced the river’s level at Cloverland’s discharge area. Low water levels there were letting air into the system. As a result, the plant’s underwater turbines couldn’t run properly.
