The Great Lakes ice cover really blossomed with the brutal cold winter. The concentration of ice covering the lakes reached a peak of 92.19% on Thursday March 6. This is just shy of the record 94.76% set during the cold winter of 1978-1979.
The ice on Lake Michigan continued to grow, reaching a peak of 93.29% on Saturday, March 8. This does set a new record for the most ice ever recorded on the lake. The old record was 93.1% set in 1977.
Of the five Great Lakes, Lake Erie observed the highest percentage of ice cover at 96.4% and Lake Ontario the least with only 61.52%. I lived in the lee of Lake Ontario twenty years ago, and that lake typically has the least ice cover and the longest lake effect snow season. Check out this link for more on this lake and the long winter season.
We should be past the peak and heading toward the spring thaw with ice concentrations diminishing.
