Well, I have given up trying to find blue catfish in Indiana for my 3rd pond (about 1/3 acre). Will stock 10 CC, 10 black crappie, and 10 RES next spring. Hopefully, the CC will grow large and eat crappie. The FHM and lake chubsuckers have had 3 years to reproduce, but I have very few plants due to the hard clay bottom. Even my lotus is struggling. Will try to add some branch piles this fall or winter. Will hopefully finish up my 4th pond tomorrow and cap the bottom drain. I am not happy with the depth, but the bottom is unworkable due to springs that seep constantly from the side opposite the dam. Hopefully, I was successful sealing sand veins under the dam, but it was hard to keep the walls of the 2' wide core trench from filling with sand washed in by water trapped in the veins. Time will tell... It's been a long hall with my small equipment.
