The U.S. Army Corps of Engineers, Detroit District, announces that Lakes Michigan, Huron, St. Clair and Erie set new monthly mean water level records for April 2020, which were previously set in 1985 or 1986. All of the lakes are either in their period of seasonal rise or are reaching their peak, as we continue into the late spring and summer.
Although the end of April brought heavy rainfall to some areas of the basin, the month as a whole was quite dry for the Great Lakes region. During the spring, water levels typically rise on the Great Lakes due to increased rainfall and runoff. In the coming months, water levels are projected to continue to be near or above record high water levels on all of the lakes, except Lake Ontario. Significant erosion and flooding continues in many locations as water levels remain extremely high.
