Great Lakes Water Levels

SONY DSC   Lake Michigan sunset at Duck Lake – from Matt Miller at ReportIt.  Check it out full screen.   The water level of Lake Michigan/Huron was unchanged in the last week.  We’ve had only 0.58″ of rain so far this month in G.R. and the river levels have come down.  The Grand River in Grand Rapids is still a little above average (5600 cfs vs mean of 5280 cfs).  The Muskegon River looks to be near average and the Kalamazoo River at New Richmond is a little below average flow now.   Lake Michigan is 7″ higher than one month ago and 5″ below the level of one year ago.  It’s still 22″ below the May average level, but 7″ higher than it was in May 1964.  Lake Superior gained an inch in the last week (mainly from snowmelt).  It’s also 7″ higher than one month ago, but is now 2″ higher than it was one year ago.  It’s still 10″ below the century average for May.  Lake Erie is only up 1″ in the last month.  It’s 7″ lower than one year ago and 8″ below the century average.  Lake Ontario is up 5″ in the last month, down 2″ in the last year and is now 5″ below the century average.   Also:  Check out the MODIS Lake Superior picture from yesterday (Thurs.).  You can STILL see several places in the Porcupine Mts. and the Keweenaw Peninsula where there is snow on the ground!  Lake Nipigon still has an ice cover.  Here’s the Lake Michigan picture, the land has really greened up in the last couple weeks.   Here’s a picture of the large forest fire burning in far NW Wisconsin.

Great Lakes News:  Grand River tested for Asian carpIllinois votes to put wind turbines in Lake Michigan.   Gobies (invasive species) have affected Lake Michigan fishing.

Model update:  The European keeps us dry until next Monday PM.  Then we get showers/t-showers (not all day rains) from Monday PM thru Thursday with a total of 2.72″ for G.R. from Monday PM thru Thurs. Evening.  The GFS (caribou) has 1.97″.

Oh, one more thing.  I got a call from near Stanton about a large dust devil that knocked shingles off their house, barn and garage.  Thurs. was a perfect day for dust devils…nearly calm winds…high sunshine…low relative humidity.  I bet there were quite a few dust devils in Lower Michigan yesterday.

    Lots of cloud cover right now, hopefully they clear up soon or we may not reach the mid 70′s at all!

      When you say “we,” does that include Oakland County? I’m sure it’s warmer over there.

      I’ll take a cooler summer over a scorching hot summer. It’s Friday, the weather was pretty nice today, particularly SE Michigan. I can’t complain.

    ‘Looking back at the loss of five feet of water over the last thirty years, he said, “you’d like to be able to say what fraction of that drop is due to climate change. And I don’t know how one would do that.”

    But climate is the major factor in changing lake levels, so even if cause is immeasurable, a correlation between climate change and low water is hardly a stretch. Global temperatures are rising, the Great Lakes region is warming, the lakes are heating up, which means more evaporation and less ice cover.’

      From the article (written in JANUARY) YOU linked to: “The U.S. Army Corps of Engineers…concur with researchers who say that further east, the deepening of the St. Clair River accounts for over a foot of permanent loss in Lakes Michigan and Huron.”

      From the Army Corps weekly bulletin for May 17, 2013: Lake Michigan is 22″ below the May average level, but 7″ higher than it was in May 1964.

      Two things to point out. First, note the lake is 7″ HIGHER than it was in 1964. Second, the Army Corps acknowledges that “over a foot of permanent loss” is due to dredging the St. Clair River. That’s most of the 22″ that we are below the century average. It’s not “global warming”, it’s mostly local dredging in the St. Clair River.
