I think that aeration is probably your best solution, since that may be an even more important factor for your pond's health during the summer!



P.S. I have lots of friends that grew up in the frozen north. Several were big on recreational ice skating with family OR trash can hockey with their buddies. I know they had some efficient methods of sweeping snow off their ponds for skating. I don't believe they had to do it TOO often during the winter?
