Thanks for the reply. There was good clay in the creek bottom that was saved for the dam and attachments. There are alot of springs and rocks in the site. I feel confident that the dam is not leaking and spread 1110lbs. of bentonite into the water already.
This is a real dilemma as I have seeded the shallow end for waterfowl and i can't stock fish until I know if I have to drain it or not. I have already lost one season for fish and may lose 2.
