The level of Lake Superior jumped up two inches in September, a month the big lake usually starts a downward trend toward winter.
The International Lake Superior Board of Control on Wednesday said Lake Superior now sits 7 inches above its long-term average but 4 inches below the Oct. 1 level in 2017. That's when storms combined with high water to cause major shoreline flooding and erosion issues around the lake.
"Additional shoreline erosion and coastal damages may occur this fall should active weather continue," the board noted in its monthly statement.
Those problems could still occur if the lake doesn't start its downward trend, which usually lasts to April before the lake begins rising through August.
Lakes Huron and Michigan declined two inches in September, about the usual amount, and now sit 17 inches above average and 2 inches above the Oct. 1 level in 2017.
