From the benchWith 53.6°F water and mostly cloudy skies, fish will be active throughout the day but the BWO window from 11 AM to 2 PM is your money shot — position yourself upstream of visible risers in the slower tailouts and seams, and make your first cast count with a long, drag-free drift on 5X or 6X tippet. In the morning, anchor a heavy stonefly like the Pat's Rubber Legs to the bottom of the deepest slots and follow it with a smaller Blowtorch or Juju Baetis as your point fly, keeping your indicator set at 1.5x the water depth. As the west wind picks up in the afternoon, move to sheltered canyon walls and lee-side eddies where fish stack up to avoid the chop and intercept drifting food.
