Lake Superior water level on the rise
DULUTH, Minn. — Lake Superior rose an inch more than it usually does in May, according to the monthly report released Friday, June 2, by the International Lake Superior Board of Control.
The big lake rose 5 inches in May, a month it usually goes up 4 inches. Lake Superior now sits 9 inches above the long-term June 1 average and 4 inches higher than at this time in 2016.
Lakes Michigan-Huron rose 5 inches in May, 2 inches more than the usual 3-inch increase. The lakes now sit 14 inches above average and an inch higher than the June 1, 2016 level.
The high water continues a trend over the past several years and has spurred some concerns over beach erosion in some areas. Both Superior and Michigan-Huron had higher-than-normal water input in May from rivers and rainfall.
