Updated Great Lakes Water Levels

Lake Michigan Sunset after Holland Sailboat Races Scott Hansen   Scott Hansen sent me this picture on my facebook page of sunset at the Holland Channel as the sailboats return from the Wednesday night race.   I was on vacation last week and my daughter (#2) and I circled Lake Michigan.   The water level of Lake Michigan/Huron is 15″ higher than it was one year ago.  Each inch represents 390 billion gallons of water, so a 15″ rise is an increase of 5.85 trillion gallons of water.  Side note – Chicago diverts about 900 million gallons of water per day from Lake Michigan or about 328 billion gallons a year, equal to about 7/10ths inch of water from the lake.  Canada diverts some water into Lake Superior, which I am told more than balances the Chicago outflow.   Lake Michigan, Superior, Huron and Lake St. Clair are all at the same water level as one month ago.  Lake Superior is 6″ above the long-term average, Lake Michgan/Huron is 3″ below the century average and Lake St. Clair is 4″ above the long term average.  Lake Erie is down 1″ in the last month, but up 5″ year-to-year and 4″ above the century average.  Lake Ontario dropped 5″ in the last month.  Ontario is exactly  at the level of one year ago and 1″ higher than the century average.   The outflow from Lake Superior into Lake Huron remains well above average.   The Grand River at Grand Rapids (as I write this) is flowing at 2,480 cubic feet per second, compared to an average flow of 1,800 cfs.  The Muskegon River at Croton shows a flow of 1,370 cfs compared to an average of 1,240 cfs.  The Fox River at Appleton WI is at 7,789 cfs compared to an average flow of 2,570 cfs.  The Kalamazoo River at Comstock is at 683 cfs compared to an average of 608 cfs.

  1. Hi everyone, I have returned! I have been very busy the past couple days and could never make it on here.

    I have yet to dig into the rain coming this weekend and the severe threat on Monday, but I will look into that a little later. Looks like tonight should be dry with showers tomorrow. By the sounds of what Kyle Underwood said at noon the most confined area for showers will be Ottawa, Kent, and Ionia Counties northward. The best chance for rain looks to be late tomorrow into Saturday.

    Enjoy your Labor Day weekend bloggers! I will be in and out during that period, but will be back on Monday obviously full time on the severe weather!
