Great Lakes water levels rising after decade-long slump
LUDINGTON, MI – Great Lakes water levels are rebounding after a decade-long slump.
A couple of years ago, Lake Superior set a record low while Lakes Michigan and Huron nearly did likewise. But they've all recovered to near their long-term average levels, while Lakes Erie and Ontario are above theirs.
Scientists say the biggest reason for the rising waters is cooler weather and greater precipitation the past couple of years.
It's unclear how long the comeback will last. Scientists say global warming may cause the lakes to recede by up to 3 feet this century.
But for now, people who suffered through the low water period are enjoying the change.
They include marina owners, commercial shippers and operators of hotels where receding water allowed vegetation to cover beaches.
