Ice on Lake Erie is more than three feet thick in some areas according to the U.S. Coast Guard.
Coast Guard crews from Air Station Detroit took part in a two-day mission in support of the National Oceanic and Atmospheric Administration on March 5.
The ice depth measurements were taken in 20 locations around the lake with depth readings ranging from three inches to more than three feet.
On March 5, the Great Lakes had a 90-percent ice cover.
Great Lakes history of ice formation shows that ice coverage typically peaks between March 10th and 15th in a typical year before starting to break up and the total ice coverage goes down. This is the most ice coverage on the Great Lakes in at least 30 years.
The ice coverage stats according to the Great Lakes Environmental Research Laboratory as of March 5:
Lake Huron: 95.94% covered
Lake Erie: 95.83% covered
Lake Superior: 95.29% covered
Lake Michigan: 92.45% covered
Lake Ontario: 43.03% covered
Great Lakes Total: 91.04% covered
