Awesome to have a 61-acre lake! Tough to intensively manage a lake that size. (A lot of the discussion about complex management on Pond Boss is for ponds ranging in size from a 1/2 acre to just a few acres.)

With your big LMB, I think it would be very difficult to get trout up to fun catching size. The trout would most likely be a very expensive snack for the bass.

I used to catch big carp for fun as a youth. However, that was always in public waters of rivers or big reservoirs. If you put in lots of carp and feed them, then I think they will reproduce and muddy the pond so badly that your fishery will be degraded for all of your OTHER fish. You could put in a few triploid (sterile) carp. They would eventually get huge over time, but will be difficult to catch with only a few in the lake.

I think getting rid of the bullheads would be almost all upside to your fishery. Perhaps start a new thread on just that topic and see if you get any helpful advice? Also, make sure you note that you are talking about a 61-acre lake in your post, so the advice will match your acres of water.

Good luck creating more fun fishing memories for the young people!
