I have caught a few crappie on Barnett on yo-yos but not many, and I have not crappie fished the lake much. I have not ever heard of anyone doing real good but I know in the spring there seems to be a lot of people there crappie fishing. I have not been there in over a year. Last time I was there was last summer four of us went green carp fishing out of two boats. We fished between the two boat ramps and me and my cousin caught some bass in the grass, the other boat thought the big fish were in deeper water and they fished the deeper water in between the two ramps and wound up catching crappie instead of bass. I think they only caught one or two but keep in mind they were bass fishing. There are some threads on the main forum talking about fishing minnows vertically in standing timber, I think Barnett would be a good lake to try that on.
nothing beats time on the water
