I haven't fished it in the winter much, but if I did, I'd try single poling the brush piles that the Dept. of Conservation has sunk. There are three fingers coming out from the dam. There is a huge brush pile off one of them. I think its the one on the right. Then if you follow the bank down the south side of the Logan Creek arm, you will find several more with your sonar. They also catch some good walleye below the dam in the winter. Good Luck
