Click on the image to enlarge. This is the shoreline by Marquette MI on 5-13-14 (courtesy of Mark Hagerman – his friend took the pic.). It looks like the Arctic Ocean seen from Barrow, Alaska! Wow! As of Thursday night, we are STILL at 13.7% ice cover on Lake Superior! Speaking of WOW! Check out the rise in water levels on the Great Lakes! Lake Superior is up 5″ in just the past week!! That’s due to rain, snowmelt and below average evaporation. Superior is now 10″ higher than it was one month ago (I have never seen a 10″ rise in a month on Lake Superior) and up 17″ in the last year! Lake Superior is now 6″ above the long-term average level. Lake Michigan/Huron (one lake for lake-level purposes) is up 3″ in the past week and up 14″ in the past year. The lake is now only 7″ below the century average. Lake Erie is up 1″ in the last week, up 4″ in the last month and up 8″ in the past year. The lake is 1″ above the long-term average. Lake Ontario is up 9″ in the past month and 9″ year-to-year. Ontario is 4″ above the century average. Lake St. Clair is up 2″ in the last week, up 6″ in the last month and up 13″ year-to-year. St. Clair is one inch above the century average. The flow down the St. Mary’s River from Lake Superior to Lake Huron will continue to be above average.
Also: Lake Michigan is totally ice-free after setting a record for ice cover in early March. End of ice-breaking on the Great Lakes. Late-season ice is slowly the start of walleye fishing in Ontario. Traverse City to build new fishing pier. Lake Huron stocked with Atlantic salmon. Great Lakes Photo Gallery.
