I was fishin just ne of green bouy very close not more than 100 yards from the bouy. Just head ne untill the water drops off to 29'. Last year I fished this area alot and caught perch most of the summer. Sometimes I will let my boat Idle for about 5 mins. when I first get there to attract the perch. First learned this from the head boat captains in port clinton. Also, use small pieces of dead minows cut up as chum. This seems to work well for the sheep head too!
