Hey everyone This will be my 4th year with a pond, so far I haven't wintered my feeder fish residents instead give them away in the fall. The pond is about 12' L 6' W and max 2' deep. Previous house owners laid concrete on chain link fence so I am working with the shape I have. I am in the process of rebuilding my waterfall and am instead building a mini rapid style design. I also raised the far side to balance out the water (previous house owners didn't have a clue how to build a pond, not one side or edge is the same) Would it be possible living in the toronto area to keep goldfish over winter in a pond this shallow? If not how would I winter them indoors? I won't have a large tank or indoor pond but water doesn't freeze in the back of my garage. Just to give you an idea what it looks like.
