I would really check out the VERY shallow water near the deep water. Crappies and gills move very shallow in the mid day period to dark. Esp. on sunny afternoons they will go quite shallow under the ice. Have seen this many times and our fish have put the early spring move on as I right this. If you have a camera don't drop it to fast because your fish will be just under the ice a lot of the time and you might just go right past them. Hope this helps.....STEVE
