15 to 20 keep fish .....hmmmmm
not an easy thing depending on who what and where for sure
some of the area lakes have the fish moving into or already set up in a winter pattern right now
this could include several options for ketchn them
spider rigging with minnows maybe in open water ?
up a creek shallow somewhere
or maybe deep parked in brush on the bottom
I don't fish any of the lakes you mentioned
but to be sure a guide could possibly get you on the fish

Rockhopper or benny Dabney maybe ?
or cliff spindle
or fishinfarmer
they fish some of those lakes you mentioned
