Updated Lake LevelsNovember 7th, 2012 at 2:22 am by Bill Steffen under Bill's Blog, Weather
This lovely pic. is from Maureen at Little Sable Point. The water level of Lake Michigan/Huron is down 2″ in the last month and down 15″ from one year ago. The lake is 27″ below the century average and 2″ above the level of Nov. 1964. Lake Superior is unchanged in the last month and down just 1″ year-to-year. It’s 12″ below the November average. Lake Erie is down 2″ in the last month and 16″ from one year ago. However, the lake is only 6″ below average (it was 10″ above average one year ago) and is 25″ above the lowest November level in 1934, a year of record heat and drought. Lake Ontario is down 3″ in the last month and 13″ year-to-year. Ontario is 9″ below the long term average and 22″ below the November lowest level also reached in 1934. The Grand River is running a little below average flow, at 85.5% of median flow. Check out the 6-12 foot (or more) waves on Lake Michigan from Sandy. Here’s beach erosion on Lake Erie from Sandy. The damage would have been worse if we had the higher water levels on the Great Lakes that we had last year.
