A: The ice cover on the Great Lakes peaked at 92.2 percent on March 6, the highest mark since 1979, and the second highest level in records that date to 1973. This is the first year since 1994 that four of the lakes – Superior, Huron, Erie and Michigan – were more than 90 percent covered. Lake Ontario was at 59 percent and typically has less ice because it has three times the water volume of Lake Erie, The Weather Channel reported. "Persistent cold temperatures in the Midwest this winter have almost completely frozen over many of the Great Lakes," the Great Lakes Environmental Research Laboratory in Ann Arbor, Mich., said in a release. Lake Michigan set a record of 93.29 percent ice cover, breaking the previous mark of 93.1 percent set in 1977, the Detroit Free Press reported.
