Cow Shoals has no fish now (
Chuck Farnsworth may catch em there now, but he's kinda special). Use wooly buggers, craklebacks, and red asses. Also, scuds and sowbugs. You'll do real well. Winkley Shoals, Rainbow Island(ask where it is, but be careful of the nut who lives adajcent to the parking lot-go downstream to the docks), Dripping Springs, and the dam (in the evening). Have fun.
