It is likely the water level of Lakes Huron-Michigan peaked in August, and will continue to fall over the next couple of months.
The mean or average water level of the lakes in August was 580.77 feet or six-tenths of an inch higher than July’s level.
While the August level was more than 17 inches above the long-term average for the month, it was nearly 16 inches below the August 2020 level of 582.09 feet, which is also the record high level for August.
The US Army Corps of Engineers is now forecasting lake levels to fall over the next couple of months at least. The Corps is predicting the water level to drop 3 inches by early October.
The all-time highest water level on Lakes Huron and Michigan was 582.35 feet in October 1986.
