i would dig your pond larger,you will find in most books that it is hard to raise bass in a pond less than 1 acre.after several years they will clean you out,all though you will find some members who work hard with there ponds and have a good exp.with smaller ponds.i think bob said it best when he said (less than 1 acre,put bream and catfish in pond)i know 2 people with ponds of 1.35 and 1.65 acres and everything has worked pretty good for them.you might try to get a min. size in this range,it will be best for the bass you put in your pond.
