There was a rather unusual phonmenon called a seiche. That’s pronounced |saysh| and it’s kind of like a small tidal wave. You can click on the link to see a very simple diagram of it. Since this particular one was heading toward the Wisconsin side, it made an extremely low tide on the Michigan side. A guy who was bulldozing sand on the beach describes it in this article. Basically, it meant you could walk all the way out to the first sandbar on dry land! Is that cool or what? I think it would be very neat to see. It’s always amazing to me how just a few inches difference in the lake water levels can make many feet of difference in the beach. The lake was up a couple inches last summer, and it cut the beach area at our favorite spot in half! This time, even though the water receded about 50 feet from the shoreline, it was probably only about 18 inches difference in water depth.
Makes me wonder how it looked on the Wisconsin side. There have been seiches on Lake Michigan that were big enough to wash people away, but not for quite a few years.
