Welcome docker. I'm in the north eastern part of the state and have never fished El Dorado but I can tell you fall crappie can be similar to spawn crappie. They sometimes come in shallow in the back of creeks where the water may be a bit warmer than the main lake. There is also a consistent deep bite this time of year. I have the best luck on the deeper bite fising breaks in 12 to 20 fow. From what I've seen, they're still pretty spread out and not one particular depth is better than another. Shad is key this time of year as crappie are beginning to feed up for the winter. I'm sure some of the guys on here can help you with El dorado.
