I am getting gung ho, plenty of bambo next door and not much in the way of structure in my pond. There is a creek bed that runs about 15 feet from the shore, but it is only 6 or 8 ft deep, where the deep part of the pond is about 20 ft, would I do better in the creek or deep? I know this because the dam on the pond has gone out twice, I think I can figure out about where it drops off from old pics. Or does any of this really matter?
