Ice is patient, and it doesn’t take a dramatic storm to damage a dock. It’s usually the slow pressure of ice forming, expanding, and shifting through the winter that does the real harm, which is why fall prep matters as much for your waterfront as it does for the cottage itself.
Floating docks generally need to come out of the water entirely before freeze-up. Left in, they can be crushed or heaved up onto shore by ice movement. If yours is a permanent or crib dock that stays in year-round, ice can still put pressure on the structure, so it’s worth checking with a local dock company about ice guards, bubblers, or de-icers if that pressure has caused damage in past years.
Boathouses need their own attention. Clear gutters and check the roof for the same reasons you would on the cottage, and make sure any boat lift or personal watercraft lift is either raised well above the waterline or removed, since ice can just as easily damage a lift as it can a dock.
If you’re new to a waterfront property, your neighbours are often the best source of information here. Ice conditions and shoreline behaviour vary quite a bit even within the same lake, and someone who’s watched that particular stretch of shoreline for a few winters will usually know exactly what your dock needs.
