To me, "nuking" a pond means either draining it and sterilizing it or not draining it and killing all the fish in the pond. That could be with Hydrated Lime or Rotenone.
BH are one of the tougher fish out there to kill to ensure that there is a 100% kill, so I would drain the pond down until there was enough water to get a boat around in it, then I would use one of the above methods and make sure that the correct application procedure was observed, and if there is any doubt, do a 2nd application about 2 weeks later.
