Check post-storm
Flow is up to 379 CFS at Falls Village (gauge height 2.24 ft), a healthy bump from last week's low-summer levels that has fish moving and feeding more confidently. Expect good clarity with the light overnight rain unlikely to muddy things up significantly.
Hatch Chart
Insect Size Activity Prime Time
Flying Ants (Terrestrial) 16-18 Moderate 10 AM - 2 PM
Blue-Winged Olive (Baetis) 20-22 Moderate 9 AM - 12 PM
Caddis 18-20 Light 6 PM - 8 PM
Midge 20-22 Light 7 AM - 10 AM
Smallmouth Forage (Sculpin/Crayfish) 6-8 Heavy 6 AM - 9 AM
Best Time Window
  • 7 AM - 10 AM: Foggy, overcast conditions trigger BWO hatches on slow seams and tail-outs — prime dry fly and emerger window.
  • 10 AM - 1 PM: Flying ant activity peaks as temps warm; dead-drift ant patterns tight to shaded banks and structure.
  • 6 PM - Dark: Evening caddis activity and cooling temps bring smallmouth and trout to the surface — skate a CDC caddis through riffle tails.
Guide's Tip
From the benchToday's overcast morning with patchy fog is a gift for BWO fishing — get on the water by 8 AM and work the slow tail-outs and flat seams in the TMA before the fog burns off. With flow at 379 CFS, the river has good push, so position yourself at the head of pools and let your nymph or emerger swing down through the strike zone rather than fighting the current. Once the sun breaks through mid-morning, shift your focus to terrestrials along shaded, undercut banks — a well-placed ant pattern dead-drifted within six inches of the bank edge can produce explosive takes. If you're targeting smallmouth, hit the rocky boulder fields and deeper runs at first and last light with a crayfish or sculpin pattern stripped along the bottom.
