Great Lakes Water Levels

October 13th, 2012 at 12:37 am by under Bill's Blog, Weather

  Picture from Robbi Boeve.  The Great Lakes water levels have dropped significantly this year, due to low precipitation and high evaporation.  Hopefully, with the soaking this weekend and a little wetter pattern, the levels will start to rebound.  The water level of Lake Michigan/Huron is down 7″ in the last month (about as big a drop in a month as we have seen) and we are now 14″ below the level of one year ago.  Lake Michigan is now 29″ below the 100-year average.   Lake Superior is down 4″ in the last month and is now 3″ below the level of one year ago.  Superior is 15″ below the long-term average for October.  Lake Erie, the shallowest of the Great Lakes, has dropped 8″ in the last month and is now 19″ below the level of one year ago.  Lake Ontario is down 7″ in the last month and 12″ in the last year.  Both Erie and Ontario are 10″ below the long-term October average.  Erie and Ontario fluctuate much more in the short term than the other three Great Lakes.  Last Christmas, Lake Erie was 18″ ABOVE the century average.   Here’s the current Drought Monitor for Michigan.  We’re dry, but not as dry as we were last July and the rain’s this weekend will wipe out a significant part of that yellow.  Also, Envisat shows sea level has dropped ever so slightly since 2008 after having risen slightly from 2000 to 2008.    Tropical Storm Rafael has formed in the Caribbean.  It’ll produce gusty winds and heavy rain as it moves up toward Puerto Rico and then toward Bermuda.  You can follow the storm on San Juan radar.   There were more waterspouts off the S. California coast on Friday (second link)  48-hr. rainfall:  0.29 San Diego, 1.84″ Las Vegas, 3.31″ Kyle Canyon, 3.54″ Grove OK.  Thunderstorms produced hail and high winds in New Mexico and the Texas Panhandle (baseball-sized hail and 70 mph winds).  That’s the storm that’s coming our way for the weekend.

    I’m hoping that this storm system and many others following during this fall and winter, will bring the lake water levels up. The inland water tables need replenishing also.

    1. Mike (Mattawan) says:

      yes, there are quite a few “swampy” and “wetland” areas that are suffering, right now those areas are dry or just mud. Im hoping this rain will help. It should…….

      This will help a little, need a long term pattern change though. Hopefully it’s coming.

      You should be thrilled by that map! The country and the PLANET will be saved!! Good luck with that. The intelligent masses are starting to see through the hope and change. 24 more days. Enjoy.

        And now I read that the GOP ‘hope’ of senate control is all but gone too. Too bad. I guess the American people really DON’T want to return to Bush economics. Huh. Go figure. LOL

          Now where did you read that, Huffington Post, Daily Kos, or were you watching our former governor Jen on NBC this morning? Say what you want but Obama is a total failure. He couldn’t run a kids’ Kol-Aid stand.

        2. Ned S. (Now in South Holland) says:

          The RCP poll I looked at this morning shows Romney aheaqd of Obama. Big Daddy, I hate to burst your bubble, but I believe Romney will win this thing. America is tired of Obama, his lying and blaming everyone else for what’s happened.

        3. big Daddy BC says:

          I love your optimism, Ned, however misplaced. The article I’m referring to is from the NY Times.

          And it’s true that Obama’s lost some ground after his first debate, but he’s well ahead still. Look at the link I posted above. Romney doesn’t stand a chance at turning enough of those swing states to win the electoral college. Heck, on top of that we’ve got two more debates. Romney’s doomed Tuesday. What the right fails to recognize is the brilliance of tanking on that first one.

        4. Bill Steffen says:

          Obama has another sympathetic moderator on Tuesday. Most of Michigan will probably be watching the Tigers and not the debate. Here’s the latest polls: …a lot of close races.

          BTW – did you notice that the libs. at MSNBC were reporting that Felix Baumgartner traveled faster than the speed of LIGHT?
