Great Lakes Ice and Water LevelsFebruary 14th, 2014 at 1:32 am by Bill Steffen under Bill's Blog, News, Weather
Click on the graphics to enlarge. GLERL reports that the Great Lakes have now reached 88.1% ice coverage and that Lake Michigan is up to 80.4%. We get the warm-up next week, but then it gets cold again for late Feb. We may not see the peak of Great Lakes ice until the first week of March.
The water level of Lake Michigan/Huron has not changed in the last month. The lake is up 13″ year-to-year and 13″ below the century average. Lake Superior dropped 4″ in the last month (very cold – less runoff, the level should hold steady in the next few weeks now that the lake is almost all ice-covered). Superior is up 10″ in the last year and is 2″ below the long-term average. Lake Erie is down 4″ in the last month, up 2″ in the last year and down 3″ from average. Lake Ontario (which has the highest percentage of open water of the Great Lakes) is down 1″ in the last month, up 4″ year-to-year and 1″ above the long term average.
