Click the images to enlarge. On the left, Environment Canada reports ice cover on the Great Lakes is at approximately 75% ice covered. This is more than double the average ice cover and we still have about a month to go until we reach the average date of peak ice on the lakes. The middle image shows ice cover at this point in winter is the greatest since 1996 and the third highest since 1980 (and may go to #1 by the end of the next week!) The picture on the right is the GLERL camera at Alpena looking out over Lake Huron. This is the latest from the U.S. National Ice Center: “Northern Lake Michigan: Open water except for consolidated thick lake ice in the northeast section of the lake, north of Beaver Island. Elsewhere in the northeastern section of the lake and along the eastern shore 9 tenths of thin lake ice including 4 tenths of medium lake ice. 4 tenths of new lake ice along the western shore. Green Bay: Consolidated thick lake ice. Southern Lake Michigan: Open water except for 9 tenths of thin lake ice within 20-30 miles of the shore from the Milwaukee to Gary. 9 tenths of medium lake ice including 4 tenths of thick lake ice along the shore from Gary to Frankfurt. Here’s the report from Environment Canada on the other Great Lakes.
The combination of Great Lakes ice, thick snowcover and a stormy spring will mean a higher potential for flooding this spring and it may mean continued increases in Great Lakes water levels. Canada looking to buy land in Detroit. Finally, thick ice means cooler Lake Michigan water this summer.
