The pictures show how the relatively low water level of Lake Michigan is affecting the Saugatuck Channel/Kalamazoo River. Click on the pictures to enlarge. The water level of Lake Michigan is up 1″ in the last month. The level is 15″ lower than one year ago and 29″ below the average water level for April. The lake is 1″ above the lowest level ever recorded in April back in 1964 and 63″ (more than 5 feet) lower than the highest reading ever for April set in 1986. G.R. had above average precipitation in the winter of 2011-12 and the winter of 2012-13. The water level of Lake Superior is unchanged in the last month and 3″ below the water level of one year ago. It’s been cold around Lake Superior and there has been virtually no snowmelt at this point. Once that occurs, the water level of Lake Superior should go up several inches. Lake Erie is up 1″ on the last month and Lake Ontario is up 2″ in the last month. Both of those lakes are 11″ below the century average. Those two lakes fluctuate much more than the other 3 Great Lakes. Lake Erie was well above average level last spring. I’ll say again that if you hear that the substantial loss of water in Lake Michigan/Huron is from lower than average snowfall the past 2 winters, that is not correct, since total precipitation (rain and snow) was near to above average during the two winters. Again, if you haven’t done so, read this article about the dredging that has been done on the St. Clair River…and you should read the articles from Mark Torregrossa in MLive. Also: GVSU wind buoy to be located offshore of Muskegon this summer. The Badger (car ferry at Ludington) will continue in operation this summer. Here’s a Michigan State grad. that’s done some significant research on salmon in Michigan…and head to Muskegon if you want some free sand for the sandbox or yard.
