Lake Superior declined about 3 inches in December, a little less than it usually does for the month.
The International Lake Superior Board of Control reported Thursday that the big lake now sits 11 inches above its Jan. 1 long-term average but 2 inches below the level at this time last year.
Lakes Michigan-Huron dropped an inch over December, less than the normal 2-inch drop. The lakes now sit 20 inches above average and 3 inches above the level at Jan. 1, 2018.
The board of control says the above-average water levels, coupled with strong winds and waves, continue to result in shoreline erosion and coastal damages across the upper Great Lakes system, noting more shoreline erosion and coastal damages may occur this winter should active weather continue.
