Great Lakes Water Levels

The top pic. was taken around 3:30 pm Sunday at the Muskegon Channel.  Hard to believe on a sunny, mid-July Sunday that there are no boats to be seen.  There were Small Craft Advisories and a Beach Hazard Statement in effect.  While temperatures reached the low 80s inland, readings reached only the mid-upper 60s with a 20-25 mph north wind.  Lot of boats stayed in the connecting inland lakes.  Water levels on the Great Lakes remain high.  Lake Superior is up 4″ in the last month, up 2″ in the last year and is now 10″ above the average water level.  Superior is only 2″ from the record high July water level.  Lake Michigan-Huron is up 5″ in the last month, up 6″ in the last year and is now 17″ above the average July level. However, it’s still 16″ below the highest July level reached in 1986.  Lake Erie is down 1″ in the last month, but up 11″ in the last year.  Erie is 19″ above the century July average and 10″ below the highest July level also reached in 1986.  Lake Ontario continues to be at a record high water level – 2″ higher than it has ever been in July (old record was in 1947).  Ontario is down 4″ in the last month, but up 30″ since July 2016.  Lake St. Clair is up 4″ in the last month, up 9″ in the last year and is now 21″ above the average July water level.  All the connecting rivers have above average flow and that should continue through the rest of the summer.

  Here’s Lake Michigan water temperatures.  We’re not as cool as 2014 and 2015, but cooler than 2012.  Remember, that was the year with the big “heat waves” in March and July.
