Don,

The link didn't work for me, so I went to NOAA again and found [url="http://tidesandcurrents.noaa.gov/ofs/leofs/fore_wl.shtml"]this color map[/url] showing the water dropping in the west, due to today's strong winds. Holy Toledo!

John,

Hmmm?...The link works for me.

From the projections in the link you provided, it appears Buffalo is in for a 7ft rise around 5:00pm today!

I went down to the marina this morning to check my boat/adjust my lines and there was already a couple of powerboats hanging from the docks. Towards the late afternoon today, we may not have any water left in the marina.

Just about the daily tide range in western Long Island Sound... BTW, if a boat is hanging, untying its lines can be quite dangerous.

Don't go paddling today on the Niagara River!

I went down to the marina after work today to check on the boat and the hull was sitting nicely on the bottom as the fin keel was buried to the hilt in the soft muck.

Here are some pictures of the marina. The first pic is of my boat which appears to have come away, hopefully, unscathed. I went down to the marina to adjust my lines at 7:00am when it was still barely floating.

Wow - cool photos!

I've heard of this phenomenon on a report on NPR a few years back, but thought it was only limited in range to a few inches or a foot. Apparently, the phenomenon has a name, which I can't recall (CRS!).

Bad news is that the tide went out, good news is you can check your bottom paint and thru hulls! All you need is a good set of hip boots to slog around in the muck.

The weather folks also mention that once the water all gets to the downwind side of the lake, it may oscillate like water sloshing from end to end around in your bathtub.

Is there a danger of an overshoot when the water comes back to westward?

Probably not, Bruce. The lake is over 200 miles long and it starts getting shallow (relatively)east of the islands that are about 60 miles or so east of Don. I haven't been to my marina in Sandusky but I called today they said everthing was still floating. We also have floating docks. As far as sloshing back, the energy required to "overshoot" would likely be dissipated as the lake gets shallower in the west.

BTW, the phenomenon is called a seiche. (say "saysh")

I saw that NPR item about 2 years ago, shortly after reading about it on this forum, while standing in a rental car line at the airport, pleased that I knew what they were talking about (thanks again to this forum).
Here's a link to explain the phenomenon:

Yep the surge was right on time. My boat is at Erie Basin Marina at the extreme eastern end of Lake Erie. Because of these surges I have always used snubbers. Most everyone here fared well. there is at least 16ft of water under the bottom of my keel on a normal day so we don't have any issues usually. The few boats that had problems were the "absentee" owners or inexperienced. I am a big guy and the wind was enough at times to move me right along.

Not real good for sailing either.Port Clinton has a gale (40+) and 12' - 14' waves offshore. I'm working in Toledo this week, so I went over (45 min drive) to check Pearl yesterday and forgot my cellphone. Today I went back for my phone and double checked my lines and sails.
