I know location is a big factor in what type of pond can work and how hard it will be to get it to work. The area I have picked out for mine is the lowest point on my property and is at the bottom of what I would call a compound hill, or bowl (slopes from the south and the west down to this area). The area stays wet LONG after everything else has dried up after rain. Alot of the plans are plants that you see in wetlands, but it is mostly grass. Does moisture on top of the ground indicate how successful a pond will be or is that water just on the surface?
