2014 Great Lakes Ice Coverage Was Earliest On Record

November 26, 2014 – Satellite image shows Great Lakes Ice Coverage formation starting on Saginaw Bay. This is on the western edge of Michigan’s thumb between Sebewaing and Port Austin. Thus the outlook for another winter similar to 2013-14 looks promising. This could result in higher lake levels and less evaporation as the ice covers and protects the lakes.

Complete ice over like the 2014 ice coverage also meant a potential for more sunshine and bitter cold during the winter months. Ice coverage prevents evaporation, low-level cloud formation, and lake effect snow.

Early Ice Coverage in 2014

2014 Ice Coverage may contribute to high lake levels last seen in the 1980s. Ice coverage on the Great Lakes typically reaches 48 percent. Historically lakes Superior, Huron, and Erie can freeze over, but not Michigan and Ontario. Ice development on the Great Lakes usually begins in late December or January. The ice coverage season reaches the maximum extent by early March. The last time that Lake Superior almost entirely froze over was in 1979.
