Tips for Fly Fishing Below Green Mountain
Seasonal Tip
This water is moving. Depth and current changes fast. High-sticking and tight-line methods rule. Dry-dropper works too, but expect short drifts and picky eats.
Dry Fly
PMDs are hot right now. Fish will rise mid-morning in seams and glides. Long tippet, slack-line casts, and stealth are key.
Nymphing
Tight-line or euro rigs dominate. Pair a size 16 anchor fly with a size 20 dropper. Use 5X fluoro and stay close to structure.
Streamer Fishing
This is a streamer river—if you fish smart. Early morning or post-storms are best. Short strips, long pauses, swing wide.
