DULUTH — Lake Superior started August by breaking the monthly high water level record, the fourth straight month that’s happened, as the big lake continues its high water trend.
The International Lake Superior Board of Control reported Friday, Aug. 2, that Lake Superior rose by 1.2 inches in July, less than the usual 1.6 inches but still enough to push the lake nearly an inch above the previous record high level for Aug. 1 set in 1950.
The big lake sits 14 inches above the 100-year average for Aug. 1 and is 9 inches above the level at this time in 2018.
Lake Superior could near another monthly record in September, but a new, all-time record now seems less likely. Thanks to dryer weather in June and July, the U.S. Army Corps of Engineers in Detroit is now predicting the lake is likely to remain below the October 1985 all-time record high as Lake Superior begins its seasonal decline toward winter.
Lakes Erie and Ontario were also at record-high August levels.
