I used to live in Jefferson City. Did a lot of throw lines on the Missouri. Throwline is about 30' of main line with five 18" droppers set about four feet apart. Window weight on the bottom, top tied to something solid - tree limb best. Used a piece of innertube between line and anything that wasn't springy on it's own. Saves a lot of fish from getting off. Set parallel to current in flathead habitat - wood or big rip rap. We used bigger bait than what you are using in the post - bought carp from the hatchery in Taberville or caught perch from farm ponds when we could. Also used big circle hooks exclusively. We killed a lot of catfish, flatheads and blues both that way. Dark of the moon in June was one peak, a good fall rise was another, and really anytime in October/early November.
