John, Here's what was happening at our end:
http://www.ndbc.noaa.gov/show_plot.php?station=45142&meas=wvht&uom=E&time_diff=-4&time_label=EDT

It looked worse! We sat comfortably behind a picture window watching the spray coming off those rollers outside the bay. The mooring field was swinging wildly and a few brave souls were trying to secure their boat covers. The view of the American shoreline was exceptionally clear as things started to calm down before sunset. Then a rainbow appeared.

Pretty amazing stuff for what some coastal sailors might call "just a lake". Of course, they haven't seen this vast inland sea. What was the water level like. I'd imagine it to be pretty high given the sustained westerly winds. There used to be a NWS chart that shows the relative water levels at the 2 ends of the lake but, I can't find it.

I grew up around Lake Michigan and have seen steep, breaking 8-footers on it many times... and I've gone out far enough to not see land in any direction. I have no illusions about the Great Lakes being "inland lakes"!

The water level in the bay was only up about a foot from this summer's average, as viewed from the beach. I expected it to go higher, but the wind was WNW, not SW. Waves were still crashing pretty high on the American shore when we drove home after 22:30. The winds had shifted more northery as we crossed the Peace Bridge.

I just realized that wave chart page updated itself hourly. It showed 10.6ft with 7 sec. intervals for a few hours when I posted it.

I went to the boat yesterday evening and as I got ready for a sunset sail, I turned on my instruments and heard a beep that I've only heard once before. My low water alarm was beeping IN MY SLIP! It's set to alarm at 5 feet. The water level was down around 2+ feet from normal. I still went out, I just stayed in the middle of the bay.

S to SW for us, and nobody was out on Saturday. We were packing the boat to head home today, but we got delayed for quite a while watching a Beneteau try to leave and then trying to get ungrounded at the marina entrance and back to his slip. My slip dropped to 3.6 feet. We don't get that kind of excitement in Waynesville, Oh (population almost 2000).

Lake sailors deal with all kinds of level variations, however they don't have astronomical charts to help them predict the tides. At least we get a cheat sheet!

Ya, ya... Just gotta get a word in for us guys who deal regularly with these currents, anchor-scope geometric exercises, and timing problems for getting out and back... There are a few times each year when my dock is completely surrounded by mud (with barely enough water in the slip to float my $+!nkp*+). And that's with a much lower tide range than I dealt with in western Long Island Sound with our C-25. And often the "cheat sheet" is at least as far off as their level changes are to their "normality". (Note that I'm in no way comparing to the folks in TX, GA, OK, etc... whose lakes slowly disappear on them. My heart goes out!)

It's pretty common to hear low water advisories for western Lake Erie at this time of year but usually it's for the Detroit/Toledo area. Where DaveB & I are (a <i>little</i> further east) is also common to see the water levels drop but I've not seen them be this dramatic. While they're not as predictable as tides, you can count on the Seiche effect this time of year when you see sustained westerly winds in the 25-30 knot range like we had Thursday-Saturday.

I've seen many seiches on L. Michigan, although because it's major orientation is N-S, a seoche is less dramatic with the more common westerly winds than with a northerly. However, at roughly 90 miles wide (E-W), it can still be significant--flooding Lake Shore Drive in Chicago during a winter nor-easterly.

When there is a strong wind from the South for longer than about 24 hours, ocean water is pushed into Galveston Bay, TX. The water level in bayous at the North end of the bay (like Clear Lake) which normally fluctuates only a few inches due to tides rises two or three feet.

Like today!

I usually have to walk down the ramp to my dock but today I had to walk up the ramp. Tides in Clear Lake are up a little over 2' above the prediction for today and approx. 3-1/4' above MLLW.

All thanks to T.S. Hermine!
