Fish two flies under an indicator with a little weight. Egg patterns and midges are my flies of choice. Sight fishing will always pick up more fish at this stream. Watch them eat your fly as they don't always move the indicator. If you can learn to watch the fish you will triple your catch.
Chartreuse seemed to be the hot color. Fish seem to be taking flies deeper. For more information please call Orvis store in Scottsdale.
