Great Lakes Ice Coverage in 2014

Historic Ice Coverage on the Great Lakes in 2014

Ice Coverage 2014

During the winter of  2014, the Great Lakes experienced near record ice coverage. In March 2014 NOAA reported 92.2% of the Great Lakes were frozen. A record only surpassed in 1979 with over 94% total ice coverage. This deep freeze over the Great lakes was viewed warmly as ice tends to prevent evaporation of the lakes and provide recovery for lake levels during the spring thaw. The coverage also meant that most of Michigan experienced a very sunny, albeit cold winter. All of the Great  Lakes experienced record low water levels in early 2014. Matching levels in 1964.

The ice impacted harbor towns across the Great Lakes. Marquette Michigan’s newspaper Mining Journal reported that Marquette harbor was opened two weeks later than normal. Icebreakers provided by the U.S. Coast Guard had to escort two freighters into the harbor. One freighter, The Barker delivered coal to the Presque Isle power plant. The delay in the shipping season forced We Energies to acquire reserve coal stock from  Marquette Board of Light and Power.

In Michigan’s Thumb, the long winter season has delayed work at Port Austin harbor.
