My Fall plans changed when I literally took a fall a week ago. Now I'm in a boot and on crutches for 6-7weeks. So the plans to put on a net didn't happen. My intake bay is pulling in a lot of them but I know I'll have some settling to the bottom as the days go on. My pond is 14x20 and 2ft to 4ft deep. I'm in zone 4. 13 shubunkins and goldfish about 6in. If I can still see the rocks through the leaves, do you think it will be ok for the winter?
