Winter midge activity peaks mid-morning to early afternoon in sun-warmed pockets. BWOs sporadically on overcast days.
Small dry-dropper (Griffith's Gnat #20 + Zebra Midge #22) or sight-nymphing with Scuds
800-2,500 CFS fishable year-round. Winter releases typically sit around 800-1,200 CFS. Summer releases can fluctuate 1,200-2,800 CFS daily.
46-56°F year-round. Tailwater temps stay remarkably stable—no thermal stress concerns.
Dam-controlled releases from Flaming Gorge provide exceptional stability. Winter flows lock in around 850 CFS. Summer sees more fluctuation for irrigation but rarely unfishable.
Crystal clear year-round. Visibility often exceeds 10 feet. Sight fishing is the norm, not the exception.
Fishable here means you can present flies effectively to feeding fish. On the Green, that's essentially year-round. The only real limiting factor is daily flow fluctuations in summer—wade fishing requires attention to rising water.
spring
Midges and BWOs dominate. Fish stack in seams and slower water. March and April offer excellent dry fly fishing before summer crowds arrive. Flows remain stable around 1,000-1,200 CFS.
summer
Cicadas (when they happen) bring explosive surface action. PMDs, caddis, and ants keep fish looking up. Watch for daily flow swings—wade carefully and be prepared to move. Early morning and late evening are best.
fall
Many consider this prime time. Crowds disappear, flows stabilize, and fish feed aggressively before winter. BWOs and midges provide consistent hatches. October and November are particularly good.
winter
Classic tailwater winter fishing. Fish concentrate in deeper runs and slower water. Midges hatch on sunny afternoons. Sight-nymphing with scuds and sowbugs is deadly. Low flows (850 CFS) mean more fish in predictable spots.
