Muddy Fork, it sounds like you already have some fertility in your lake. Spreading some good black dirt in the lake will add to the fertility.
You have already added predators in the form of the catfish. How big are your bluegills? If they aren't big enough to spawn this year, get some that are! They will spawn immediately and there is your forage for the LMB. The fathead minnows will provide some forage while all of this is happening. The most important thing you can do is get some large spawning bluegills into your lake immediately.
