If it's a creek on the shallow side, I can't tell you or I'd have to kill you but it beats anything anybody will mention. A clouser type on a fly rod or cheated with a regular rod/reel is the next best productive unless they're sluggish/tight-lipped after a cold front and held up in deeper holes. A lot of folks will go to a fluke-style bait or whatever jig and work it real slow or bounce it off the bottom. But I've outcaught these folks many of times with slightly faster erratic actions. If it's deeper than usual but not too deep a rat-l-trap or Mirrolure 4M are hard to beat. Deep water vertical my fav is Little George. It just works.
