The pond on our farm is largely spring fed (undeveloped, but there nonetheless) and of course it receives a great deal of surface water due to the surrounding topography. Its been the color of chocolate milk for a few years now. I'd like to drain the pond and start over since the fishing is terrible, but I'm curious about the silt issue. I've seen folks say catfish, turtles, and even crawldads can cause this. I can't imagine it's a silt issue from runoff given the ground cover upstream, so I'm inclined to think it's the doing of a creature. Thoughts and experiences from this group as to what the issue may be are greatly appreciated.
