we were on american ponders [ i think] and it is gone so you are stuck with us now . two ponds , one small about 2500 gals and 12x20 feet . one large about ?????? gallons and 100x400 feet shared with about 7 other houses with none on the long south edge . small one is about 6 years old and has savio filter and waterfall . most interesting thing with ponds is blue heron which shows up often and eats ..........''CHIPMUNKS'' ....which we have an excess of until heron helps out . oh , there is a fountain in large pond and ,fortunately , it is at the end of our driveway . . . . peace
