Dry fly fishing will be sporadic but epic hatches of blue winged olives and straggling trico's can still happen this time of year in the canyon. An ideal rig for the flows and conditions right now will be a nymphing rig consisting of an indicator for easy adjustment from hole to hole and 2 flies near the bottom. When water and air temps peak for the day look for fish to move into shallow riffles to sun and warm themselves and feed. In this case a dry dropper rig will be best for stealthy presentations.
The coming week 10/22/14-10/31/14 looks to be nice with no chances for precipitation. With that being said fishing should be good with plenty of sun in the forecast to warm up the river's.
