DULUTH, MN (KDAL) - Lake Superior rose a whopping 9 inches in May, the second largest mark for that month since 1918. Officials from the International Lake Superior Board of Control said that on average the lake rises just 4 inches in May, but that late snowmelt coupled with above-average precipitation in the Superior basin led to a near-record month. Lakes Huron and Michigan also recorded above-average levels in May. Superior levels are expected to rise again in June, meaning ships should be able to transit the lakes with heavier loads.
