I used to fish over there a lot, but spent all of my time there upstream from McFarland Park, in the Wilson Dam tailwater.  Good smallie, white bass, hybrid, striper, and the ever present Tennessee River drum.  I'm not sure if the skipjack would still be there this far into the summer.  The tailwater is kind of rocky and shallow, if the generation is low.  It would actually be perfect for your jet boat if you haven't sold it yet.
