I cut the dam on a 60 or 70 year old pond I own about three years ago and will be attempting to seal that dam back up in another couple years - focusing on finishing / improving my small lake right now. If you get any good pointers, please share them.

I know it can be done though as a neighbor did it about two years ago with his 2 - 3 acre pond and I don't think they did anything special.
