I've done well at times at Salamonie at the flats just North of the modern campgrounds. Not a lot of big crappie, but good numbers of 7-9 inch fish with usually a few 11-12 inchers as well. I haven't experienced the water being below the ice line but have heard the story enough from different fishermen to believe it can happen. Be careful driving down on the flats until the ground is completely frozen, especially if you are by yourself. My dog and I had a long walk to the nearest phone last year.
