Summary

Flows are holding steady with cold overnight lows tightening trout into softer winter seams. Clarity remains solid, making stealth and depth control the deciding factors between slow days and steady action. Midges continue to run the show with isolated Baetis pulses during cloud cover, but most feeding remains low and subtle. Crowds are light, and anglers willing to slow everything down are finding consistent nymph eats. Expect a classic November pattern of late-morning activation and fish glued to deep walking-speed water.

Pro Rig of the Week

Winter Depth-Control Nymph Rig for Big Water
Leader: 10–12 ft 5x fluorocarbon
Top Fly: Chocolate Thunder size 20
Dropper: Black Beauty size 22
Weight: One or two micro shot 6–10 inches above top fly
Indicator: Yarn or medium air-lock, set deep for 4–7 ft troughs
Why it Works: This stretch demands depth first. Midges stay low, trout stay glued to winter buckets, and this setup keeps both flies in the exact strike zone for the full drift.

Access Points

  • Pumphouse Area ⭐⭐⭐⭐
    Classic broader runs with dependable winter seams. Best clarity here. Fish the slower inside lanes and defined mid-depth shelves.
  • Below Gore Canyon Trail Access ⭐⭐⭐
    Colder but holds good fish in deep bowls and soft transitions. Nymphing heavy is key. Limited surface activity.
  • Radium Area ⭐⭐⭐⭐
    Productive softer water along the edges. Good walking-speed winter troughs and less pressure than summer months.

Local Regulations and Notes

Artificial flies only in designated sections.
Watch for shelf ice forming overnight near shaded banks.
Flows stable with minimal fluctuation.
Respect private-property boundaries outside access corridors.
