I've counted three Green Frogs in our pond. We'll have to be sure to nab them before the pond ices over to avoid their dying as the oxygen level drops (they must be used to deeper lakes). The current plan is to give as many away to local nature centers as possible, and to put the rest in an aquarium. No worries; they'll all be returned to the pond once Spring rolls around.

Speaking of wildlife that have issues overwintering. Then again, maybe the DNR (and whatever Canada has) take care of these 'fresh water whales' the way we take care of our pond frogs (only on a largeer scale), removing then when/if Superior freezes over and move them into the Duluth Aquarium.
