When to go The blue-winged olive hatch is the first really productive hatch of the year. It generally starts at the end of March. By April, the hatch is becoming fairly consistent, with any overcast or rainy afternoon producing excellent dry fly-fishing from Secret Riffle to Washboard Rapid. When the blue-wings start to fade in late May, the cicadas begin to show up and can be very important through June. These large terrestrial insects have a cyclic population, so they can vary a great deal from year to year.
Fishing can be difficult for one to three days after a major change in flows.
In recent years, an effort has been made to change flows gradually, as abrupt changes are detrimental to fishing. When flows are stable, fishing can be good at a wide range of levels. Red Canyon Lodge 790 Red Canyon Rd.
