The water level of Lake Michigan (and Lake Huron – they’re at the same water level – connected at the Mackinac Bridge) is up one inch in the last week (and 1″ higher than one month ago).   That’s because of increased precipitation (esp. at the south end of Lake Michigan – Michigan City, Indiana had 2.7″ of rain Thursday and Thursday Night) and low evaporation.  The Grand River in Grand Rapids is at 186% of average flow at 7:45 PM Friday evening.   Rainfall since June 1 is about 3″ above average in Grand Rapids.  Lake Michigan/Huron stands 11″ higher than last year and the lake is now only 4″ below the long-term average level.  Lake Superior is up 3″ in the last month, up 1″ in the last year and 4″ below average level.  Lake Erie is 6″ above one year ago and 3″ above the average level.  Lake Ontario is at the same level as one year ago and 4″ above the average level.  Look for gusty winds of 15-25 mph from the WNW at the shore on Saturday, with occasional showers and 4-7 foot waves.  There is a possibility of a waterspout, with cold air aloft coming over the water waters, but the wind is a little more than you’d like to see for waterspout formation.  Have a great weekend.
