  • Focus on mid-day warmth; early morning is ice and shadows.
  • Target deeper runs and slow edges near structure.
  • Use long leaders (10–12 ft) and 6X tippet for clean drifts.
  • Walk light — the canyon amplifies sound, and fish are skittish.
  • Expect a small bite window but great color and solitude.
