I fish all year round, and use the same pattern unless it is spawn. I fish structure in 8-14 ft of water depending on the lake level. The crappie are always just off the bottom around this structure, and when I say around I mean that you don't need to fish right in the structure. I think the crappie cruise around and and around the structure, because sometime you can get a bite and then nothing for a few minutes and then another. This can go on for a while and then you may catch several fish before the pattern starts again. So i don't know, but it seems to me they are either going around or in and out, what ever. I have caught fish at Tbird in the same structure in this same pattern all year round. I have caught them in 104 degrees and 36 degrees out of the same spot, sam depth. So all my ideas from years ago about how to fish crappie i threw out the window about 10 years ago when I put my fist structure in the lake.
