The fall turnover is when the cool air temps start cooling the upper level of water. When the upper level gets cooler and heavier it will go down. This mixes the water at all levels and reduces the amount of oxygen.
Fishing will be very difficult in most of the water because there is a low oxygen layer everywhere. You have to search for the fish but when you find them they’ll be bunched up together. Fishing is great but only when you find the right spots that has more oxygen. The fish may be very shallow, very deep or anywhere in between. The crappie may be difficult to find but when you do you can load the boat.
Within two weeks after the turnover, fish will be aggressively feeding and eager to bite your live or artificial offering.
