Lake Michigan sunset from March 8 by Jack Martin submitted to ReportIt. Click here to see the picture full screen. The water level of Lake Michigan/Huron is up one inch in the past month. It’s down 14″ in the past year and is 26″ below the long-term average. However, the level is now 2 inches higher than the lowest level for March, reached in 1964. The highest level for March occurred in 1986, when the level was 58″ higher than it is today. Lake Superior is down one inch in the last month (though it’s going to go up when the snow melts up there…Thursday morning, the Marquette Airport had 41″ of snow on the ground, Twin Lakes was at 39″ and high honors goes to Hoist Basin with an incredible 56″ of snow on the ground! They are working toward five feet of snow cover!). Lake Superior is still UP one inch in the past year and remains 11″ below the century average. Lake St. Clair is up 6″ in the last month. Lake Erie and Ontario were both up 2″ in the last month. Lake Erie is still 7″ below the long-term March average and Lake Ontario is 4″ below the long-term average. The Grand River flow at G.R. at 2:30 AM Fri. was 10,300 cubic feet per second, compared to an average for 3/15 of 6,800 cfs. River levels are above average. Also, the Army Corps of Engineers has just surveyed the Kalamazoo River at Saugatuck and found it deep enough for cruise ships and why Door County, NE of Green Bay is windy.
