Smallie action is nothing. Crappie will start moving over the shallower cribs and into the shallower waters. Use crappie minnows or hair jigs, just fished under a bobber. Start to go deeper than in the summer pattern. They will come up as far as ten feet or more to hit a lure, so try different depths.
Locals swear that anyone can catch a Butternut musky under full moon.
By the way, Butternut is notorious for catching big musky on large suckers, up until ice in. Don't expect some big slab crappie to follow a bait downward, but it will follow and hit a tasty minnow that it can see overhead. Forget perch to a great extent at this time of year. You might get an occasional big bluegill while fishing for crappie, but don't count on it. Bluegills aren't much in Butternut, at any time.
