I fish a 6-700 acre lake it has no bottom structure and one little cove, it gets progressivly deeper from one end to the other 3ft to 30ft, no sharp drops or shelves either. Most experts always referance creek channels deep cover and structure, but on a lake similar to a swimming pool where does a guy look for Cold weather Crappie? there is plenty of blow downs and sunken brush along the banks but they are in shallow water 3-8fow.
