I'm in central OH and have a 1/3 acre pond that is on its' 3rd year. Looks great, fish are doing great, but...when I see blue water at the base of the spillway and in the creek, I know the crawdads have dug a tunnel around it again!
I can't find it until the pond level gets down to where the hole is. It's usually knocks about 6" off of the pond depth. Not the end of the world, but I still don't like it. When I find the hole I pour in some bentonite and/or pound a rock into it. That seems to help until the next time.
Any ideas?
Thanks!
