Well, I fish there a lot since I live in Sullivan. I don't know if they are back in the deep, but they are definitely not working the banks. Fished about 3 hours last Sunday and only caught about 20 in the shallows. You may want to do a little Walleye fishing while you are down, my buddies went this morning and caught about 14 keepers. They were catching them on lipless crankbaits, Lew's Speed Vibes, to be exact. Said they hooked into a couple 14-16" crappie while fishing for the walleye. They were fishing mostly off of rocky points and along the bridge on the north end. Most of the Crappie in Lake Sullivan are on the small side, but occasionally we get some big ones out of there. Last year a guy caught a 3lb 4oz slab. Good luck, I may see you out there.
