Best Time Window
- 8 AM - 11 AM: Nymph the deeper pools and runs tight to the bottom as fish warm up and begin actively feeding.
- 11 AM - 2 PM: Prime dry-fly window as BWOs hatch in the tailouts and flat water; switch to a size 22 parachute or emerger.
- 4 PM - 6 PM: Late-afternoon caddis activity picks up along the banks; work a CDC caddis through the riffles before last light.
Guide's Tip
From the benchWith water temps at 44.4°F, trout metabolism is slow — don't rush your drifts. Focus your morning effort on the deeper, slower pools where fish will be stacked and less willing to chase; use a tight-line or indicator setup and keep your nymph within 6 inches of the bottom. As air temps climb toward the mid-60s between 11 AM and 2 PM, watch the flat tailouts for BWO activity and be ready to switch to a size 22 dry — fish will visibly rise and a long, drag-free drift on 6X tippet is non-negotiable. Avoid wading through the prime pool heads; approach from downstream and stay low.
