Seiche!

Not sheesh, but seiche, although sheesh! seems appropriate under the circumstances.

We awoke to find this fine mess, although overnight there was no big storm and no big surf. Puzzling a first, but then the realization that the only explanation was a seiche, the Great Lakes equivalent of a tsunami. Some online checking showed the hypothesis to be correct. A big Lake Superior seiche flooded parts of Sault Ste. Marie, and another sieche hit the west shore of Lake Michigan.

That's the one that I think got us. Caused by storms with large differentials in atmospheric pressure, a big wave starts sloshing around the Lake, and as in a bathtub, takes a while to settle down. At three this afternoon the water was way, way down; this evening (about 6) I watched in real time as the water rose over a rock that has never been submerged this year. Once again we are in flood.

We had to move the Susie Pea and the green kayak up to higher ground, and then tie and weight the pier in hopes of preventing it from floating away.

Sheesh.
