I am struggling to catch any crappie once the water temp drops below 50 degrees. I have been primarily fishing Logan Martin, and I know the crappie are around somewhere but I haven't been able to figure them out.

What types of patterns do yall look for once the water temp gets in the 40s? Are there certain depths of water you look for, or depths you rule out?

I did ok shooting docks and fishing brush in 15 to 20 ft until the water temp dropped more. Thanks in advance for any info, I still have a lot to learn.
