Therefore I try to carry all three types of live bait with me when I am on the water. Many anglers like to cast the rig to the edges of the clumps, but I like to use a variety of flipping methods made popular by bass fisherman. A long rod, maybe even a cane pole, is rigged with a jig. When fishing is tough, a slip bobber and hook rig is used to work the bait through and around the individual clumps of weeds. You can fish a large area in a short time, and probably catch some nice fish.
Chartreuse is a good color for fall walleyes in the weeds.
When the fish are real active, try an action tail body, like a twister body and work it with quick hops. In the weeds you need a line you can depend on. In open water I like 4 and 6 lb. test, but in the weeds, you need a heavier less abrasive line. Eight or ten pound Easy Cast or Sensor line are what I count on for fishing the weeds. One last thought.
