Best Time Window
- 8 AM - 11 AM: Morning midge nymphing in tailouts and slow pools before the sun hits the water.
- 11 AM - 2 PM: Prime BWO hatch window — switch to dries and emergers as fish begin rising in the flats and seams.
- 2 PM - 4 PM: Terrestrial and caddis afternoon window along grassy banks before wind gusts make presentation tough.
Guide's Tip
From the benchWith flows at 1,910 CFS and gin-clear water, stealth is everything — stay low, approach from downstream, and use a long 12-14 ft leader tapered to 6X. The BWO hatch will fire hard between 11 AM and 2 PM when the sun warms the water surface; position yourself in the A-section flats and watch for subtle sipping rises in the slower water adjacent to the main current seam. Pre-hatch, run a heavy nymph like the Silver Bullet deep through the bottom of pools where big browns are staging. The SSE wind gusts to 25 mph this afternoon, so get your dry-fly fishing done before 2 PM when the wind picks up and makes presentation difficult.
