Lake Michigan Water Levels

July 11th, 2012 at 1:00 am by under Uncategorized

  Picture of a Lake Michigan sunset at Sleeping Bear Dunes (look how calm the water is).  Here it is full screen (from Mark at ReportIt).  The water level of Lake Michigan stayed the same over the past month, but is now 8″ below the level of one year ago.  It’s 20″ below the long term average for July and 11″ above the low-water mark of 1964.  Lake Superior has gained water after heavy rain fell in the Duluth area (9″ in 2 days).  Superior is up 6″ in the last month (over 3 TRILLION gallons of water added to the lake in just a month!) and is now 3″ above the level of one year ago. Both Lake Ontario and Lake Erie have dropped with the dry conditions this early summer.   Erie has lost 3″ in the last month and is now 5″ below the century average.  Ontario is down 2″ in the last month and is 6″ below the century average.   The water level of the Eastern 2 lakes can vary significantly over a relatively short period of time of several months, while the other 3 Great Lakes are slower to change.  Since 70% of the equation for the water level of Michigan/Huron is the water coming down the St. Mary’s River from Lake Superior, the gain in water to the north should keep Lake Michigan from getting too low if these drought conditions persist through the summer.

    If you are going to let your grass go into drought mode, please water it for 30 minutes once a week. That will keep the root system in tact, and keep insects and disease from eeking in.

      Watering mine for an hour two to three times a week and about 50% of my lawn is in drought mode… if I’m lucky. We need more people doing the rain dance :)

      Not letting the grass go into drought mode yet…. but im about to… watering the grass 30 minutes every day (6 hrs total for whole yard) and the grass is barely staying green. Im about ready to just give up watering until we get some good rain.

    Summer Time in West Michigan, Enjoying it!!

    CPC says above average rainfall in the 6-10 day range. While I hope this happens I do not believe that forecast for a second!

    We are in Munising it has been a very warm day up here and sunny up until about a hour ago and guess what we had a rather good rain shower with heavy rain and this is the only rain for many miles around. On the car’s outside themother we had a highest reading of 87 and now down to 75.

    Bill: The blog entry states “Since 70% of the equation for the water level of Michigan/Huron is the water coming down the St. Mary’s River from Lake Superior”

    I love your blog but the skeptic in me makes me wonder about this. I’m thinking that there must be a lot of water coming down the St. Mary’s River in order to make this true. I’ve never seen the river, but it must be a big one.
