I would agree with eyehi. I usually fish underwater structures, and usually stay away from flats. Sometimes I will fish off points or in front of bays that hold bait fish and panfish. Tonight for example, the three of us had nine tip ups out and we had five tip ups we had on drops offs and the other four we had up on a flat and those didnt get any flags. But the five flags we had 17 flags on. Some days the bite better one shiners and other on small suckers. I usually switch them every other tip up. I use the lightest mono for a leader as I can get away with. with the smallest sinker that will take the minnow down the hole with a size 12 treble hook. The other spot I would try is just southest of the 25' hole where is goes 3' to 5' to 10' and 15' looks to be all within a hundred yards. Its a underwater finger/point. This time of year i do try to stick to deeper structures during january and in december and feb i try stick to shallower structures.
