For the third consecutive year in a row, severe winter weather was observed throughout the Great Lakes region. Ice conditions were especially severe in the western Great Lakes, where average temperatures were almost 4F below normal. In addition, the Lake Michigan basin experienced record snowfalls with blizzard-like conditions several times during the winter. A total of 114 vessels, plus 10 foreign ships, and an estimated 25 fishing craft participated in the extended-season operations. This was down slightly from the previous year. The cargo tonnage carried by commercial ships directly assisted by the Coast Guard was less than half that of the previous season. The figure is misleading, however, because the number of preventative icebreaking missions performed by the Coast Guard fleet doubled this year.
