Lake Michigan High Water Infographic

 

Fast Facts:

  • Lake Michigan water levels are running at near-record high water levels thanks to a longer term wet pattern, especially within this past year.
  • The lake was near record low levels in early 2013, then in the past six and a half years the water levels have increased six feet.
  • Lake level records at Calumet Harbor go back through 1903 and are based on monthly averages. The record was observed in October, 1986.
  • Impacts of the high lake levels have already been felt, with multiple minor lakeside flooding episodes this spring and summer in wind speeds that would normally not cause minor flooding. This included flooding of parts of the Chicago bike path.
