I agree that your 19-acre pond is a different (and potentially favorable) situation. It is really a small lake.
Maybe you can run a small experiment with some F1 bass? Buy what fits in the budget and mark them with floy tags and track their progress.
I don't see how they could have a significant negative impact on your overall fishery. (But I am not an expert on that topic!)
They could have an impact on your wallet, but I assume you are keeping the money trees on your ranch well-watered during this drought.
