Blue River Below Green Mountain Big Water Quiet Canyon and Trout That Still Surprise You

  • November 7, 2025

Blue River Fly Fishing Report near Green Mountain Resevior

 

If the Blue below Green Mountain had a personality, it’d be your favorite guide — calm, powerful, and totally unpredictable.

Flows are ideal for late fall, the canyon is quiet, and the fish are spread between deep tailouts and slow seams. Clarity is excellent, and this week’s stable weather means consistent feeding windows from mid morning through early afternoon.

The hike in can feel longer than it is, but the payoff is real: fewer anglers, thick fish, and long runs that reward patience and clean drifts.

Pro Rig of the Week

Guide setup: Run a 10 foot 4x leader to a #16 Egg Pattern or #18 Scud as your lead fly and trail a #22 Black Beauty 20 inches below on 5x. One micro shot above the lead fly and a medium AirLock indicator about 1.5 times the depth.
Drift tight to seams and along drop-offs where fish slide between depth changes. Focus on tailouts below riffles and soft water against rock walls.
