Its pretty much anywhere around the reefs. I think if you are looking for bigger you need to go deeper. I have a friend that fished both the reefs and between SB and Kellys last week. He said he caught smaller ones around the reefs. I think he was fishing in front of Besse on the reefs. He caught some very nice walleye's between the islands and north of Bass. He caught 2 fish Ohio walleye's in about 35-40 fow north of Kelly's. One was 29 and the other was 31.
