Flow is running at 86.6 CFS (gauge height 0.95 ft at Rainbow Springs) — slightly elevated from two weeks ago but still clear and fishable, demanding precise presentations. Frost overnight and a sunny high of 63°F Sunday will push the best dry-fly action into the midday window once air temps climb.
Best Time Window
  • 8 AM - 10 AM: Midge and heavy nymph fishing in the deeper runs and seams before the sun fully warms the water.
  • 10 AM - 2 PM: Prime BWO hatch window — switch to emergers and dries in the tailouts and flat pools as fish begin rising.
  • 3 PM - 5 PM: Afternoon caddis activity along riffled edges; also a good time to swing a streamer through the deeper pools before light fades.
Guide's Tip
From the benchWith frost overnight and a slow warm-up to 63°F, don't rush to the water at first light — the fish will be sluggish until air temps climb above 45°F around 9 AM. Start with a single heavy nymph like the Silver Bullet or Perdigon in the deeper slots to get down fast in the slightly elevated 86.6 CFS flow, then watch for the BWO hatch to ignite between 10 AM and 2 PM when the sun hits the water. At that point, switch to a dry or emerger and target the flat, glassy tailouts where fish will be sipping confidently in the clear water — use a long, fine tippet (6X minimum) and a reach cast to buy yourself a drag-free drift of at least 4-5 feet.
