Erie, Huron and St. Clair are famous for it. I think Green Bay as well.Every winter chucks of ice break off of some lake supieor shore and ice fisherman are on it. These piecs are sometimes large, like miles in size.
I've seen videos of that. Crazy. The most I've ever seen is about 22" of ice. Here, on warm days, we get the drain effect. You drill a hole and any melt water on top of the ice starts draining into your hole, bringing all the dust, dirt, and debris into a swirling current, like a toilet bowl.Same situation - different story. We spent a year in Glennallen, AK. Doofy's arena. Ice fishing in February. Had a four foot hand crank ice auger. DISAPPOINTMENT - the four foot auger would not reach all the way thru the ice. Then - many times - you end up with a "overflow" situation. Weight of the ice has pressurized the lake water and you have a never ending flowing spring or geyser.
