Hatch Chart
Insect Size Activity Prime Time
Blue-Winged Olive (Baetis) #20-22 Moderate 10 AM - 2 PM
Caddis #18-20 Moderate 4 PM - 7 PM
Midge #20-22 Light 8 AM - 11 AM
Golden Stonefly (Nymph) #12 Light 7 AM - 10 AM
Terrestrials (Ants) #16 Light 12 PM - 4 PM
Best Time Window
  • 7 AM - 10 AM: Early nymphing in pocket water and riffles with stonefly and caddis nymphs before the sun hits.
  • 10 AM - 2 PM: Prime BWO hatch window — switch to Baetis nymphs and watch for rising fish in tailouts and slower seams.
  • 4 PM - 7 PM: Evening caddis activity picks up along foam lines and edges — dry fly opportunity with CDC caddis patterns in low light.
Guide's Tip
From the benchWith flows at 502 CFS and water temps at 59.2°F, trout are actively feeding throughout the day — don't sleep in. Start your morning in faster pocket water with a stonefly or caddis nymph bounced tight to the bottom, then transition to a Baetis nymph setup in the 10 AM–2 PM window when the BWO hatch typically fires. As afternoon temps climb toward 80°F, shift your focus to shaded undercut banks and deeper pools with a crayfish or sculpin pattern stripped slow and low. Keep your indicator set at roughly 1.5 to 2 times the water depth and watch for subtle hesitations — fall fish on the Truckee can be deliberate biters.
