Drier-than-normal conditions continued to help Lake Superior move closer to normal water levels in March.
The International Lake Superior Board of Control reports that Lake Superior dropped 0.8 inches in March compared to the usual 0.4-inch drop. Lake Superior now sits 7.1 inches above the long-term average over the past 102 years, but is also 7.1 inches below the April 1 level last year.
Lake Superior now is expected to begin its usual seasonal rise, peaking in late summer or early fall before dropping again by October.
Lakes Michigan and Huron were unchanged in March, a month they usually slightly increase, and now sit 24.2 inches above average and 12.6 inches below the record April 1 high of 2020.
