Great Lakes Water LevelsMarch 22nd, 2013 at 7:19 pm by Bill Steffen under Bill's Blog, News, Weather
Sunset Splash on a windy, March evening at Holland. (picture from Beach Bum Joe at ReportIt). See it full screen. Some good news. The water level of Lake Michigan/Huron is up 2″ in the last month. The level is still down 13″ year-to-year, but it’s now 4″ above the lowest March level, which was recorded in 1964. The lake level is 25″ below the century average (a one-inch improvement from last month). Here’s precipitation above average since Jan. 1: Grand Rapids +2.44″, Lansing +1.65″, Kalamazoo 0.46″, Alpena 1.54″, Houghton Lake 2.51″, Detroit 1.39″, Flint 1.85″, Milwaukee +2.93″, Green Bay +3.01″. Lake Superior is down 1″ in the last month, but that should reverse as the very deep snow cover (39″ near Houghton and Marquette and 58″ south of Grand Marais) melts. Lake Superior is one inch higher than one year ago. Lake Erie and Lake Ontario are both up 2″ in the last month. Lake Erie is 7″ below average and Lake Ontario is 4″ below the century average. If you haven’t read this article about the effect of dredging the St. Clair River on the water level of Lake Michigan/Huron, please take the time to read it.
Also, today is World Water Day. I salute the Rotary Clubs for their great effort to provide clean drinking water to millions around the world. Gov. Snyder will sign a bill appropriating 21 million dollars for 49 dredging projects around the state. Here’s pictures of Michigan lighthouses in winter. Surf’s up!
