Fished for flatheads in Hannibal pool: Friday: We used frozen shad. We caught a 12 and 7#. Saturday: We used live blue-gills and creek chubs. We caught 6, 7, and 9# within the first 20 minutes and missed 4 more. I made an effort the keep the bait in the strike zone while they were in the feeding frenzy. Good weekend on the river bank with the nice temperatures.
