I am very interested in the replies, but afraid I won't be much help. I would say that the fish will seek bait,correct water temperature, and habitat in some order. I think I would spend a good deal of my fishing time where the two rivers come together. You said it around twenty feet deep, so you may find some weeds or humps or dropoffs. Take note of the surface temperature compared to other parts, but measurements could be much different down lower. The Lake may "turnover ",but usually not if any flow is involved. Pay some attention to your electronics, not only looking for crappie, but also for bait, weed edges, humps and ledges, and hidden wooden structure. Good luck
