Did you try gravel bars in 3 or 4 ft of water? Seems like they are always around the gravel bars.

If all else fails, crickets around the KDM docks are hard to beat. The stake beds in KDM are usually pretty good too, and all of the riprap. There's really no need to even leave KDM. Used to be a guy with a TINY little rig, not much bigger than a lawnchair really, who would put in at the ramp, and spend all day in there and take home a huge mess of bluegill each day. I was always in awe that he didn't turn that little rig over.
