Big Red Lighthouse picture from Jack Martin. Wow did the strong north-northeast winds do a number on water temperatures. Here’s what we got Saturday: 49 Grand Haven and Holland, 50 Saugatuck, 55 Ludington. BRRR!! This lake level report was from before the rains that we had Thurs. and Fri. Lake Michigan/Huron was down 2″ in the last month and down 10″ from one year ago. It’s still 9″ above the level of August 1964. Lake Superior is unchanged both in the last month and year-to-year. Lake Erie is down 4″ in the past month and down 13″ from last August. Lake Ontario is down 5″ in the last month and down 11″ year-to-year. Both Lakes Erie and Ontario are 7″ below the century average. These two lakes fluctuate more than the other 3 Great Lakes. Lake Erie was 17″ above average level last Feb. 3rd. Here’s where you can check Michigan river levels. You’ll see some dramatic rises on rivers in parts of S. Lower Michigan. The volume of water in the Rogue River at Rockford tripled on Friday. The Pine River at Midland is interesting. The volume increased 10-fold in less than 24-hours and the level got to nearly twice the previous highest level for any August 10th. It looks like it’s already the 5th highest level ever (66 years of record there) and still climbing.
