Flow is running at 1,790 cfs with a gauge height of 9.29 ft — double-peak fluctuating releases have kept fish a bit off rhythm, but water temps are a comfortable 60.4°F and clarity remains fishable. Terrestrials are picking up the slack as caddis, PMD, and Yellow Sally numbers continue to taper.
Hatch Chart
Insect Size Activity Prime Time
Caddis #18-20 Moderate 6 PM - 8 PM
PMD (Pale Morning Dun) #18-20 Light 9 AM - 12 PM
Yellow Sally (Small Stonefly) #14-16 Light 11 AM - 2 PM
Terrestrials (Ants, Beetles) #12-16 Moderate 10 AM - 4 PM
Midge #20-22 Light 7 AM - 9 AM
Blue Wing Olive #22 Light 1 PM - 4 PM
Best Time Window
  • 6 AM - 9 AM: Pre-sun midge and early PMD nymphing in slow pools and glassy flats before flows fluctuate.
  • 10 AM - 1 PM: Terrestrial dry fly prime time — work ant and beetle patterns tight to shaded banks on the A Section.
  • 6 PM - 8 PM: Evening caddis emergence; focus on riffle-to-flat transitions with CDC caddis patterns before dark.
Guide's Tip
From the benchWith flows at 1,790 cfs and the double-peak fluctuation pattern still in play, time your nymphing sessions to the stable flow windows — typically early morning before the first release bump. On the A Section, walk the bank edges and cast terrestrials (ants and beetles) to any visible riser holding within 2 feet of the bank; these fish are keyed on the surface and won't move far for a fly. When afternoon thunderstorms build after noon, drop to a nymph and work the deeper inside seams of B Section bends — the cloud cover and slight pressure drop often triggers a short but aggressive feeding window. Keep leaders long (12-14 ft) and tippet fine (6X) in the clear tailwater conditions.
