Great Lakes Water LevelsJuly 2nd, 2014 at 3:05 am by Bill Steffen under Bill's Blog, News, Weather
This is a picture of Kollen Park in Holland on the shores of Lake Macatawa. I was there last night for a little picnic and to hear the fine Holland American Legion Band – that band has been together for 95 years. They play free concerts Tuesday nights in the summer. Lake Macatawa connects to Lake Michigan, so the water level of the lake goes up and down with the water level of Lake Michigan. We’ll (I’ll be at this Park Party) be there in Kollen Park for the next Maranda Park Party, which will be July 10.
The water level of Lake Michigan/Huron is up 3″ in the last month. The lake is 10″ higher than it was one year ago and is now just 5″ below the long-term average. Lake Superior is 4″ in the last month. Superior is 13″ higher than it was last year at this time and is a full 7″ above the century average. Lake Erie is up 1″ in the last month and up 7″ year-to-year. Erie is 4″ above average water level and Lake Ontario is unchanged in the last month and 5″ above the long-term average. Lake St. Clair is up 3″ in the last month, up 10″ in the last year and 4″ above the century average. Outflow out of Lake Superior down the St. Mary’s River into Lake Huron is expected to be above average through July. Outflow from Lake Erie down the Niagara River, over Niagara Falls and into Lake Ontario is also expected to be above average flow.
The 10″ of water added to Lake Michigan is (at 390 billion gallons per inch) 3.9 TRILLION gallons of extra water in the lake since one year ago…a pretty amazing jump.
The south mid-Lake Michigan buoy remains at a very cold 46°. I see the N.Y. Times has noticed the higher lake levels. Note the article says: “…the Great Lakes are now abruptly on the rise, a development that has startled scientists…The International Joint Commission, a group with members from the United States and Canada that advises on water resources, completed a five-year study in April 2013 concluding that water levels in the lakes were likely to drop even farther, in part because of the lack of precipitation in recent years brought on by climate change.” That obviously hasn’t happened. CO2 and the water levels of the Great Lakes do not make a good match. Also, Great Lakes shipwrecks…lowering the threshold for “contaminated” beaches…and…using the cold waters of the Great Lakes to cool industry.
