The lower river has entered the usual summer doldrums. So go to the upper river for best fishing. Box Canyon offers good nymph fishing with you favorite small bead head patterns or medium sized rubber legs. On the Harriman-Last Chance reach the brown drakes are winding down, so spinners and caddis bring best evening action. PMDs bring mid day action with emerger patterns producing best. Later in the afternoon flavs emerge and bring action.
