I have caught crappie on cranks in every month except January and February if I recall correctly here on kentucky lake. While I haven’t caught limits in these cold water temps I have picked up a few and they were usually hogs. In the early spring months while pulling jigs I will swap out to cranks and hit the main channel and creek channel in the bay searching for these large fish for an hour or so. I usually do this after Harlie and I have our bank lunch break. I have caught many many fish on cranks in November and December here on kentucky lake. Several people ask me what was the water temp and my reply is always the same, I don’t know I was just fishing. Go drop them in the water and troll buddy. Good luck.
