Wesley,
You didn't have 11" bass on patrol last year. Have your bluegill started eating yet? I read in PBmag that the bass won't eat the food but they eat what eats the food... I am new and don't know much about pond mgmt yet, but I do know how to fish for bass. If there is a place for them to ambush feeding bluegill they will do it. May be a threat management problem over a desire to eat on the bluegill's part. Do you have any shallow, flat bottom water where you could move your feeder?
