The latest report on Lake Michigan water levels, from the Detroit District of the U.S. Army Corps of Engineers (COE), shows the level 17 inches above the long term average.

2020 was the year with the highest monthly mean lake level; 1964 was the lowest, some 48 inches lower than present.


Lake water levels, due to rains in July, have risen by as many as five inches, with the Lake Superior basin the exception.


Water levels on Superior are down an inch because of a drier-than-expected July in the Lake Superior watershed.


Although all the lakes are higher than in June, in September they are expected to decline.


The COE is predicting that Lake Superior will be near its current level in the first week of September, but levels in Michigan, Huron, St. Clair, Erie and Ontario will go down somewhere between two and five inches
