Flow has dropped to 6,110 CFS at the Red Bluff gauge (gauge height 1.92 ft), down from 6,780 CFS last week, with clear water and improving wading access throughout the system. Fall Chinook are pushing through in good numbers with steelhead right behind them — this is prime time to be on the water.
Hatch Chart
Insect Size Activity Prime Time
Baetis (Blue-Winged Olive) #20-22 Moderate 10 AM - 1 PM
Caddis #18-20 Light 5 PM - 7 PM
Midge #20-22 Moderate 7 AM - 10 AM
Salmon Egg Drift (natural) #10-14 Heavy 7 AM - 12 PM
Stonefly Nymph #6-8 Light 6 AM - 10 AM
Best Time Window
  • 6 AM - 9 AM: Low-light nymphing through the deep current seams with egg and stonefly patterns before boat pressure builds.
  • 10 AM - 1 PM: Baetis hatch window on the flats — switch to small emergers and dries for rising trout in the slower water.
  • 5 PM - 7 PM: Evening caddis activity near the banks; fish CDC caddis patterns and streamers along undercut banks as temperatures drop.
Guide's Tip
From the benchWith flows at 6,110 CFS and dropping, wading access is opening up fast — focus your morning sessions on the deep gravel runs and current seams where trout are stacking directly behind and below staging Chinook. Set your indicator depth so your flies are ticking the bottom in 3 to 5 feet of water, and use enough split shot to keep them honest. As the day heats up toward 90°F, trout will push into the shade of undercut banks and deeper slots — slow your drift down and let the fly linger in those zones. Evening is your window for surface action: walk the softer flats and watch for subtle sipping rises before the light goes flat.
