I can understand unwillingness to drain. Who knows the vagaries of rainfall & how long it might be until the pond refills?
Would you consider using rotenone to kill off existing fish population? I fear that it will be difficult & time consuming to turn things around, compared with restocking. Even after culling LMB, what's left might be too old to make up for lost time.
Other people here are real experts, which I am not. Maybe they have better advice for you. Personally, I'd be excited to restart a pond in your neck of the woods, with fish like F1 LMB, SMB, RES, BG, Tiger Musky, perch, etc quite doable. You have more options than we do here in Texas.
