The level of Lake Superior dropped in November after brushing with near-record highs in previous months.
The International Lake Superior Board of Control on Monday said Lake Superior dropped 3.5 inches in November, more than the usual 2-inch drop for the month.
The decline is thanks to a drier-than-normal November that saw less rain and snow, and less inflow from rivers. The lake level had increased in September and October, two months it usually goes down some.
Lake Superior still remains 11 inches above its long-term average for Dec. 1 and 6 inches higher than at this time last year.
The near-record high water levels were blamed for magnifying the effects of recent Lake Superior storms, increasing shoreline damage and erosion.
The level of Lakes Michigan and Huron dropped 2 inches in November, slightly more than normal. The lakes sit 19 inches above their long-term average and 10 inches higher than Dec. 1, 2016.
