Lake Michigan sunset by Ted Swoboda. The water level of Lake Michigan/Huron (they are connected up by the Mac Bridge, so for level purposes, it’s one big lake) is unchanged from one month ago. However, the lake level is down 7 inches from June 30, 2011. The lake is 19″ below the century average, but still a foot higher than the low water point of 1964. The highest water level Lake Michigan has had in recent decades was in the fall of 1986. From 1964 to 1986, the lake level rose over five feet. Lake Superior picked up a lot of water from the system that dumped 9″ of rain on Duluth in just 48 hours. Lake Superior added 2″ of water in 24-hours (that’s 1.1 TRILLION) gallons). Superior is 5″ in the past month and is 2″ above the level of one year ago. Superior is still 7″ below the century average. Lake Erie is down 3″ in the last month and is now 15″ below the level of one year ago. The lake is 6″ below the century average. Lake Ontario is down 1″ in the past month and is 15″ below the level of one year ago.
