Thanks for the questions, I will try and clarify...

I use the term watershed, probably incorrectly, as it is my largest pond on the property and built by the state soil conservation department for flood control. It was the primary pond receiving all of the watershed.

The hybrid LMB I refer to are F1's, florida Strain.

The original stocking 8 years ago was done by the previous land owner and the bass genetics were those of the F-1 variety. I don't know that much about bass genetics so I hope that answers your question.
Not sure I understand your genetics refreshing exactly. I know mixing natives, with floridas, or crosses can have some type of value but have not really studied that too much.

My objective is trohpy bass fishing. I do not intend to stock additional crappie or channel cats but those were already put in the lake by the previous owner. Actually we are taking out all crappie caught, have not been many but the few we have caught have come out.

I am just trying to restore the forage base and enhance the bass numbers to get on track with this existing lake. Everything I have read has had the focus of getting a healthy bluegill forage base in place and then possibly adding some shad to propel the bass to the trophy range.

I have not considered shad as I thought the first order of business would be to restore the forage base and improve bass numbers. I have read about the benefits of shad stocking when trying to get the bass to that trophy category.

I included Hybrid bluegill as I thought a mixture of all types of bluegill was of benefit in developing the forage base.

The current bass being caught in the flood control are very, very healthy.

There seems to be some crayfish and frogs in the current environment.

The Flood Control is kind of my problem fishery as the depth is not where I would like it to be and the water turbidity is not what I would like. Many have told me you can have a great fishing lake that is shallow and we are catching some nice bass, just few and far between.
I know enhancing this fishery is going to take some time but want to do the right things to get it on track. It has potential.

Let me know if you have any more questions.

Thanks,
