Dan, I haven't seen any burrowing creatures such as muskrats since I've been here. However, I do know this: the dam has suffered from seepage for years. It was built for livestock (pigs or hogs, I don't know the difference). It has also been overgrown with small trees for a long time, which may have contributed to the problem. It's probably for the best that I re-do the pond now before spending the $$ on stocking, etc. However, it will be expensive. What I need someone to tell me is what the process is going to be like. And how much money it is going to take out of my rapidly shrinking bank account. \:\(
