DULUTH, Minn. (AP) A new report says the level of Lake Superior has made a big jump.
The International Lake Superior Board of Control reported Friday the level of Lake Superior jumped 9 inches in May. That's more than twice the normal monthly increase and the second most for any month since 1918.
Lake Superior usually rises only about 4 inches each May. But thanks to late snow and a cold spring that held back runoff, May more than made up for the difference.
The lake now sits just 7 inches below its long-term average for June 1. It is a full 3 inches above the level at this time last year.
Lakes Huron and Michigan also continued their rise from near-record lows in late winter.
