Pond up front is about eight feet. Should not have catfish in there, but it is where I put my river caught fish to clean up during the summer. Can never recatch all of them and I really didn't try this fall. Got burnt. The bass and bluegill normally do not have any problem. With runoff and rain this spring that pond is up to the overflow pipe and now 35 feet deep. Pretty, but lifeless.
The back pond is about 15 feet. Did not seem to have problems. Have bluegill, hybrid bluegill, shellcrackers, Largemouth and catfish in there. It is aerated from a pump in my barn but I didn't turn it on this winter. I just use this pond as my bait source, bluegill. This year I will catch out some catfish. They are my buddies and I feed them. Fun to watch. I catch out a few and replace them with stockers about 6 inch. I can't stand to eat bass so I just let them keep getting bigger. This pond is now full also, about 22 feet. Won't know how it did till I try and fish it. They are talking late drought here this year and we will have to see how it goes into the winter this fall. May need to turn that aerator on. hate to do that because it stirs up too much bottom sediment. The pond is very fertile and it can cause me to have algae bloom in the spring which can kill 'em as fast as ice can.
