Great Lakes that have completely frozen include Lake Superior, Lake Huron, Lake Erie, and Lake Ontario. Lake Michigan is the only Great Lake to have never frozen entirely.
Freezing temperatures force the lake to develop an ice shelf. On windy days, waves are driven toward the shore. As these waves crash into the shoreline, they also hit the ice shelf. This pushes the water up through the air.
Of the five Great Lakes, Lake Erie typically reaches the highest annual maximum ice cover, often exceeding 80 percent. Throughout the past fifty years, Lake Erie has reached a complete ice cover (100% ice coverage) three times – in 1978, 1979, and 1996, and reached 99.8% in 1977.

This can be dangerous as you might think you're walking on solid ground, when actually you're out over the water. Due to the layered nature of shelf ice, even if you're out over four feet of water, if you were to fall through a thin spot in the ice, you could find yourself trapped in an ice cavern.
As of February 14, 2023, ice covered only 6.6 percent of the five freshwater lakes, which is significantly less than the 35-40 percent ice cover that is typical for mid-February, according to data published by the National Oceanic and Atmospheric Administration's (NOAA) Great Lakes Environmental Research Laboratory ( ...
Lake Michigan is one of the five Great Lakes of North America. It is the second-largest of the Great Lakes by volume and the third-largest by surface area, after Lake Superior and Lake Huron.
Great Lakes that have completely frozen include Lake Superior, Lake Huron, Lake Erie, and Lake Ontario. Lake Michigan is the only Great Lake to have never frozen entirely.
If water were most dense as a solid, lakes would freeze from the bottom up, eventually freezing solid. In that case, little or nothing would survive in the lake. Most lakes and ponds don't completely freeze because the ice (and eventually snow) on the surface acts to insulate the water below.
The long-term average annual maximum ice cover is about 54%. Lake Michigan, which generally doesn't see peak coverage until at least mid-February, could see nearly 38% surface coverage this season, just below its long-term average of about 41%.
While there have been past “sightings,” most have turned out to be pranks or misidentifications. The reality is that the largest of the Great Lakes (Lake Superior and Michigan) are extremely deep lakes that are too cold for sharks.
The heaviest lake-effect snow in the United States falls on the Tug Hill Plateau, south of Watertown, N.Y., at the eastern end of Lake Ontario, making this region one of the snowiest places in the United States. Syracuse, which is south of Tug Hill, is one of the snowiest bigger cities in the United States.
