DETROIT, MI — The U.S. Army Corps of Engineers in Detroit announced Tuesday that based on preliminary data, new record high monthly average water levels were set on Lake Superior, Lake St. Clair, Lake Erie and Lake Ontario in June.
Authorities say the new record levels set last month are between three and four inches higher than the previous records for the month, which were set in 1986 on Lake Superior, St. Clair, and Erie, and in 2017 for Lake Ontario.
Records for those lakes are the highest for any month dating back to 1918.
The Army Corps says additional record high water levels are possible on all the Great Lakes and Lake St. Clair this summer, especially due to the wet weather throughout the month of June, which was the third consecutive month with above average precipitation across the Great Lake basin.
