Todd Anderson #5  Todd Anderson #1Todd Anderson #4  Todd Anderson #3Todd Anderson #2The person who sent me these pics. in late April wished to remain anonymous.  This is snow around Petosky, the Mac. Bridge and Mac. Island in mid-April.   As of Friday AM – we still had 9″ of snow on the ground in Copper Harbor, Atlantic Mine and Mohawk and 3″ south of Munising.  Marquette (airport) was down to a just a trace of snow and some piles.   I had a call/email Thursday that the last pile had melted at the Spartan Stores lot in Byron Center and the last pile was down to a trace in Whitehall.  If you fine any snow left, leave a comment or send a picture (email bill.steffen@woodtv.com).

The Great Lakes have all seen significant rises in the last month:  Superior +4″, Michigan/Huron +8″, Erie +8″ and Ontario +19″ (that’s right 19″ in a month! – the lower lakes fluctuate more and more rapidly).  Lake Superior and Lake Erie are both right at their May average.  Lake Michigan/Huron is 12″ below the century May average (it’ll probably be down to -8 or -9 from the May average by the end of the month) and Lake Ontario is 2″ above the May average.   Here’s the year-to-year change in water levels:  Superior +13″, Michigan/Huron +11″, Erie +7″ and Ontario +8″.  The Army Corps of Engineers expects the water level of the lakes to rise 2 – 6″ in May.  Lake Superior’s flow down the St. Mary’s River is expected to be above average during May.

The 5/3 (00Z)  ice percentage shows 7.1% ice cover on Lake MichiganLake Superior still shows a 40.7% ice cover, Lake Huron is at 16.3%, Lake Erie (the southernmost Great Lake) is at 0.5% ice cover and Lake Ontario is totally ice free.

Also:  Great Lakes Ice ImpactsCould there still be a little ice on Lake Superior on June 1?…Traffic Jam on Lake Huron…”We pretty much lost April” and Cliffs Natural Resources, based in Cleveland, Ohio, said that the Great Lakes experienced more than 70 days of -30 degrees F (-34.4 Celsius) temperatures during the winter.

    Glad to see the lake levels going back up. I am sure the Great Lakes shippers are happy.

      Kayakers are happy, too – there had been a rumor going around that the state was going to make small paddled boats get registered, and the money gathered used to dredge the shipping channels :-(
