I've had very good success this year using glow skirts at 6-10ft in 12-16ft deep muddy water. They really liked the pink/chart tail tubes with chart. crappie nibbles. Used 1/32 jigheads in still water and 1/16 where there was a little current. Once I got them biting, I'd leave off the crappie nibbles until they slowed down or quit and then put'em back on. Fishing Red River in Louisiana, but it's colored alot like the Mississippi. Got the skirts from www.barlowstackle.com, but I've seen that Bass Pro has some in their catalog. Hope this helps and that you catch all you can haul.
