Has anyone ever fish killed a pond? I allowed a neighbor commerical fisherman to put in some very large catfish and I think they are eating everything else in the pond. Have tried fishing them out without success due to the numerous turtles. I have about a one-acre, spring-fed pond in which I can drain out about 2/3rds of the water volume. I can refill it in about a week by daming up a spring run and diverting water through the normal discharge pipe. If you have done so, what procedures did you use?
