I know there's quite a few from the Carver forum who call Lake Erie home. I recently found this on the Environment Canada web site and found it so intriguing, I thought I'd share.....

High Winds Tilt Lake Erie's Surface 4.7 metres
An incredibly sharp Arctic cold front with very powerful winds in its wake passed through the Great Lakes region on January 30.

Behind the cold front, there were very strong westerly winds, with the highest wind reading – 126 kilometres per hour – recorded at Port Colborne at 6 a.m.

Sustained winds pushed the water in Lake Erie toward the eastern end of the lake, causing a maximum positive surge (a short time-period increase in water levels often referred to as storm set-up) of 2.95 metres above pre-storm levels at Buffalo, NY. As levels rose at the eastern end of the lake, there was a corresponding negative surge (or set-down) at the western end of the lake. At Toledo, Ohio, levels fell 2.39 metres below pre-storm levels. Although the maximum positive and negative surges did not occur at the same time, for a short period of time during the storm the difference between water levels recorded at Buffalo and Toledo was more than 4.7 metres. In fact, the tilt in the lake's surface from one end to the other was more than 4 metres for more than 4 ВЅ hours and in excess of 3 metres for almost eight hours during the storm.

The storm also caused smaller, but notable, surges at other locations around the Great Lakes. For example, at Goderich and Parry Sound on Lake Huron, water levels rose approximately 0.4 and 0.6 metres, respectively, for a short period of time. On Lake Ontario, levels at Kingston increased by 0.5 metres as levels at Burlington dropped roughly 0.4 metres.

Please be Cautious

As the January storm demonstrates, local water levels can rise or fall dramatically in a very short period of time due to meteorological disturbances. Large wind-induced waves are usually superimposed on these short time-period changes. LEVELnews readers are reminded to exercise extra caution when near the water's edge during a storm event.
 
We're VERY aware of that down here on the Gulf Coast!
 
I guess no matter where you boat you have to be concerned about phenomena such as this. Down in Barnegat Bay NJ I have seen a 37 footer run aground in the entrance channel to a marina (yes I was the navigator that day [:-ouch]!) because strong west winds blew all the water out of the tributaries and lowered the water nearly 2 feet. Also, go over to the HRCC thread and see what happened to my wooden deck the other day on the Rondout Creek, when the damn creek went up only half a foot above flood stage. Last year the water came up so high it floated some of the cabin cruisers off their storage jackstands. With bad weather forecast tonight and tomorrow, so close to the last big rainstorm, I'm on pins and needles that its not going to happen again...

I don't want my valuable Carver to get damaged!!!
 
does it mean how could just glide down from one end of the lake to the other? :-)

and some people are bitching about gas prices!
 
P. the answer is "yes". But look where you'd be!
 
They are called Seiches and they happen in various degrees fairly often. We had a mild one last summer that messed up a couple docks at our club. The water came up about 2 - 3’ in just a few minutes. It goes back down about as fast. I have seen pictures from the west end of Lake Erie with boats sitting on the bottom. We are in the central basin so we always get an increase. I have never heard of one going east to west.

We've get them as well on Georgian Bay, strong winds out of the east and suddenly that foot of water that was under under the keel is only a couple of inches, but we've never experienced anything like 2.95 meters...thats nearly 10 feet. I'm guessing it has a lot to do with how shallow (realtively) Lake Erie is.
 
We see Seiches on Lake Michigan as well. Maybe not as pronounced as Lake Erie due to the water depth, but one day, sitting in the slip, all of a sudden, an inrush of water came by, and it was like we were in a fast-moving river. A few minutes later, it went the other direction.

I would have hated to be trying do dock a boat then.
 
awboater,

I experienced the same thing about five years ago. We were fishing on Lake Erie off of Rocky River, OH and we saw a large storm approaching. Just after we got the boat tied down a large current of water came up river, raising the river about two feet. Our floating docks slowly creaked and moaned as they rose with the seiche. After about 10 minutes, the storm passed and the water quickly exited the river as fast as it came up.

It was really cool to see.
