IMO, you really need to read the thread on relative weights and download the chart for Largemouth Bass.
If your bass catches have good relative weights, then your pond is almost certainly healthy.
However, bass are cannibals. If they have eaten most of their forage fish, then they will next eat up your smaller bass.
I believe in the short term, that would produce a pond with mostly big bass. However, over the longer term it would be a recipe for disaster.
I suspect I am wrong (hopefully), but you should definitely check some relative weights on your LMB and maybe fish with some tiny minnows or bits of worm to sample your forage fish populations and perhaps some of your small bass.
Finally, are there any Florida-strain LMB genetics in your pond? If the answer is "yes", then I think you should be able to achieve a 10# bass in Alabama. If you maintain a healthy population distribution of fish species in your pond, and then manage specifically for trophy bass, you can probably hit your goal.
I would start keeping catch records of weight and length. Report those on the forum with your goals for the pond, and there are some members that can give you expert management advice from that point.
Keep having fun with your big bass!
