Flow is running at 1,140 cfs with a gauge height of 1.02 ft at Grants Pass — low and crystal clear, demanding stealthy approaches and precise presentations. Water temperature is 51.6°F, right in the sweet spot to keep fall steelhead and resident trout active throughout the day.
Best Time Window
  • 7 AM - 10 AM: Prime midge and early BWO window; fish tailouts and glassy flats with small dries and nymphs before full sun.
  • 10 AM - 1 PM: BWO hatch peaks in the riffles; swing Poachers and Straggle Stones through steelhead runs while trout rise in the seams.
  • 4 PM - 6 PM: Evening caddis activity picks up; skitter a Corn-fed Caddis through the shallows and swing streamers through the deeper tailouts as light fades.
Guide's Tip
From the benchWith 1,140 cfs and gin-clear visibility, stealth is your biggest advantage today — stay low, approach runs from downstream, and keep your shadow off the water. For steelhead, work the swing through the bucket at the bottom of each run using a 10-12 ft sink-tip and a Sparkle Minnow or Poacher; let the fly hang and breathe at the end of the swing for a full 5 seconds before picking up. For trout, target the seam between fast and slow water with a tight-line nymph rig, keeping your indicator no more than 1.5x the depth above your fly. The 75°F afternoon high will push fish into shaded, oxygenated water by 2 PM — focus your dry fly work in the morning before the sun hits the flats.
