I don't know anything about that particular dock system.

Do you have aeration at your pond? I know some of the members put a diffuser in shallow water by the dock. Helps the fish with oxygen during the winter and keeps strong ice away from the dock.

Does your dock system have a means of sliding up and down on posts as the water level changes? If so, another option would be to install the posts too long and lift the dock up such that the floats are above your expected winter water line and clamp it in place.

In Galena, you might get away with zero damages most winters. My cousins have a place way north of the border in Canada that has a fixed dock on a large lake. About every third year, the ice breaks up funny and their dock is still encased when the wind moves the big floes and their dock gets damaged. "Dock repair" is then one of the first jobs on the list the next spring.

In Ohio, if you just walk out on the dock with a big iron tamper bar and broke a circle of ice out around the dock during the spring thaw, that might be enough to avoid damage?

Lots of Ohio pond people on the forum. Hopefully some experts at about your latitude can give you some better advice.
