Has lake Michigan ever frozen all the way?
Wave action and wind, combined with the vast reservoir of heat contained in the lake, have so far prevented complete freezing. Lakes Superior, Huron and Erie have frozen over in a few harsh winters since 1900, but Michigan and Ontario have never attained complete ice coverage.

How many of the Great Lakes are frozen over?

How is the ice cover in the Great Lakes?
With no real robust areas of cold air in the future, the long-term forecast for Great Lakes ice coverage also looks meek. “The Great Lakes region is experiencing warmer-than-usual weather, and the max ice cover is projected to be 30%, way below the average of 53%,” Wang said.
When was the last time Lake Superior froze over?
In that time, the lakes have surpassed 80% ice coverage a mere five times. The lowest ice coverage was in 2002 when ice coverage was only 9.5%. The last time that Lake Superior almost entirely froze over was in 1979 when the lake reached 94.7% ice coverage.
Why is there so much snow in the Great Lakes?
Lake-effect snow is prevalent at the end of fall and early winter, but usually by January, it starts to ease up, thanks to the lakes themselves freezing over. “Like a hurricane in the ocean, the water in the Great Lakes is the “fuel” for lake effect snow,” said CNN Meteorologist Dave Hennen.
