The US Army Corp of Engineers is forecasting lower water levels for Lakes Superior, Michigan and Huron. High temperatures coupled with lack of snowfall in the upper Great Lakes are contributing factors to the decline. Lake Superior is expected to continue to face lower water levels from 2011 and is expected to drop another two inches over the next month. Currently lakes Michigan and Huron are 7 inches above the water levels measured in 2011.
NOAA’s National Ice Center is reporting that most of the Great Lakes region has not frozen over and open water is reported on all the lakes except for Lake St. Clair.
Overall the water level of the Great Lakes’ basin continues to approach historic lows. Low water levels in the 1930’s and again in the 1960s was weather related. Will lake levels continue to decline because of evaporation during these warmer winters?
