It will freeze over during the winter but I could put a small heater in
it to keep it open and there is plenty of plant life on both sides of
the pond. Is it possible that they could winter there?

If they hibernate in the pond you'll want to keep a hole open, either bird
bath heater or small pump on shelf moving the water. Air pumps/stones are
also another options if in Zone 7 and up, lower zones should still have a
heater as back up.

Some frogs (treefrogs) prefer to sleep in leaf litter, so don't clean the
flower beds around the pond till late spring. ~ jan
