I finally remembered to take a couple pics tonight of how I used the rip rap at my pond access points for water. I got the idea here on the forum (I think it was Sparkie). Anyway, since I have put this approach in motion, my pond no longer turns to chocolate milk color when it rains. The visibility barely changes even after a 2 inch downpour. I have two major waterways that you can see here and each are receiving approximately a 30 acre watershed. My thought on using the same approach to "filtering fish" is that if it works for tiny soil particles it ought to work on fish.
I have the pond at low pool now to add the rip rap. When full, only a foot or so of the rip rap on the shoreline will show.
