Bout 4 years ago I had a new 1 acre pond dug which I never could get to stop leaking. While I was getting it dug I drained a small 1/4 acre pond and had him clean it out and make it deeper. It gets allot more run off than my new one and does not leak. I am considering having my small pond redone and made to about 1 acre. Talked to a guy that says we can just make the damn bigger and longer.Dig it out without disturbing the original small pond.As it fills it will just have a small pond in the middle of the big pond.He wont do it now though cause we are in a bad drought. Does this sound feasible? Think it will be ok? Original small pond never has leaked and gets good run off.
