No colder than I used to deal with in Ontario. And we had regulars in
Ottawa and Sudbury who managed to keep them in no deeper ponds than that,
without heaters.

When they die here in the winter in shallow ponds, and a bubbler us used,
they claim it was hyper chilling. Disturbing the water layers until the
bottom layer was too cold for the fish to survive.

Hal's advice on bubblers is exactly what I would have given.

If there's no heater wouldn't the bottom warm layer mix with the colder
upper layer and "chill" the bottom to the same temperature as the top (near
freezing) layer?
