Click the pic. to enlarge or even better, click here. This is the S. Haven Lighthouse with a good deal of ice. This picture came to us from Jack Martin at ReportIt. The water level of Lake Michigan/Huron (these 2 great lakes are at the same level, connected up at the Mac. Bridge) is down one inch in the past month and continues to be at a modern day record low level for February. We’ve one inch below the previous record low for February set in 1964. We are 61″ (that’s over five feet!) lower than the modern day record high level for February set in 1987. There continues to be concern about the dredging of the St. Clair River that has significantly lowered the water level of Lake Michigan/Huron. The level may go up an inch with the rains we had this week. Grand Rapids had 4.01″ of precipitation in January and Muskegon had 5.48″ (3.45″ above average). Precipitation over the past 25 months has actually been above average in Grand Rapids. Rivers are high in Lower Michigan. The water level of Lake Superior is the same as it was at this time last year. 30% of the equation of the water level of Lake Michigan (not counting the dredging) is what comes down the St. Mary’s River from Lake Superior.
