  • 11 AM - 2 PM: Terrestrial dry fly fishing tight to shaded banks; hoppers and ants along grassy edges.
  • 5:30 PM - Dark: Prime sulphur and caddis hatch window; work tail-outs and flat runs with dry flies and soft hackles.
Guide's Tip
From the benchWith water temps at 68.9°F, concentrate your dry fly and nymph fishing in the first two hours of daylight when the river is coolest, then shift to shaded pools and deep runs during midday. The evening sulphur and caddis hatch is your best shot at surface action — position yourself at the tail-out of a pool by 5:30 PM and watch for the first risers to establish a feeding lane before you cast. Monday's incoming storm system means today is likely your best window of the week, so make the most of the evening hatch. Keep fish in the water and minimize handling given the warm temperatures.
