MyFishFinder.com Just like iceshanty but warmer
I fish a private lake that has huge humps that I think are tailing piles from being mined. The depth goes from 4-7' to 22-25' within ten or twenty feet in spots. If I fish the drop-off in twenty feet of water I always mark and catch fish super suspended fish that are venturing off the side of that shallow water . Maybe your situation is similar. A big drop off.
Crappie notoriously suspend high in deep water..... It isn't always BS when someone says they we're catching specs in 40fow 1' under the ice.... Crappie are an odd species
I would say that is were the food is...
