Professor Gronewald explains Great Lakes levels rebound

According to a recent brochure from NOAA’s Great Lakes Environmental Research Laboratory (GLERL), 2014 saw the second above-average seasonal rise on Lakes Superior, Michigan and Huron.

This comes as a surprise since the brochure also states there were record low water levels in January 2013.

“The quick recovery has stifled an effort to engineer a solution to the problem of low lake levels in Huron and Michigan,” the article states.

Professor Drew Gronewald, told Michigan Radio that the lakes were low mainly because of evaporation.

“It’s really that sustained high water loss through evaporation that we believe kept water levels low despite, in fact, above average precipitation for much of this time,” he said.

Michigan Radio also interviewed those interested in engineering a solution to the extreme water levels.
