Thing about it is, is my dam is leaking when my pond is at full pool. Not real bad but it is leaking in 2 spots. I would say one is a leak and one is more like a seap. And I got trees all over my current dam. So sooner or later I am going to have to redo this dam or make pond bigger and make new dam? That's why I am asking. I figure if I am going to have to clear trees and fix dam, if it's not to pricey why not go a little bigger while I am doing it.
