I usually hit rip rap around bridges during spawn. Worm or liver 3 ft under bobber close to rip rap gets fast action on channe cats. Spring Summer ater hard rain hit backs of creeks where water is running into arm and fish worms liver or cut shad. Tore them up for years following hard rains bank fishing turkey,maze,turnback bridges. Limb line up big and little sac rivers with black perch nice flatheads up both rivers during summer months. Know guys that kill'em drifting flats with shad. Dont know much about that but bitethis could probably line ya out on it. Do most of my catfishin now on truman more big blues up that way. Good luck hope this helps.
