Pike will move back to the shallows as long as decaying weeds haven't severely lowered oxygen content in shallows and coves. If that has happened they will be shallower but on the outside of dead weeds.
The best lures to use are the usual pike baits: Spinnerbaits, big spinners, buzzbaits, jointed minnows, soft jerks, and the like.
They can be very active feeding to fatten up before winter, which in winter they tend to feed less, especially here in Colorado. Here they are on the hunt for panfish and small trout. Still they tend to be most active early in the mornings and in the evenings. Once the water falls below 50 degrees they tend to get less active and start settling into winter feeding patterns, in which you have to use deadbaits or small livebaits and be very patient.
