Pat,
IMHO your assessment is probably correct. Too many LMB. You might be on the way in the future to having a pond with a few big LMB, a whole bunch of stunted ones and not much else. I subscribe to the philosophy that you must periodically assess your pond and develop an appropriate harvest plan to keep the pond in "balance." From the info provided, I would aggressively harvest 14 inch and smaller LMB in your pond.
Not a pro...just my 1 cent.
Funny Bill when I started this pond thing with BCP I was told not to harvest any LMB to offset the BCP..... seems the only thing spawning is BG and LMB.
Caught 19 LMB in about 30 minutes (10”) while trying to catch BCP. Caught 4 today in 10’ water were I normally get BCP.
