It is a very unusual winter for the northland and Lake Superior. The water level in the big lake usually drops during the winter but this past December the water level rose. It only rose 1/2″ but that is quite significant because it usually drops 3″ in December.
According to the Duluth News Tribune,
“The lake received its highest water supply for December in 116 years of accurate records, according to the International Lake Superior Board of Control.
Lake Superior now sits 9 inches above its normal Jan. 1 level and 1 inch below the level at this time last year.”
Above average precipitation and warmer temperatures are responsible for the rise in Lake Superior’s water level.
