Green River Fly Fishing Guide Report & Flaming Gorge Dam Water Flow Release
This Week on the Green

Flows hold steady between 1,500 and 1,700 CFS with cold, clear tailwater and a full late-summer hatch menu. PMDs dominate mornings and evenings, terrestrials own the midday heat, and caddis close out the day in the shade.

Below is the current dam release status, water temperature and clarity, hatch timing, our recommended fly box, and a full tactical breakdown of Sections A, B, and C. Floating remains the most productive way to cover water and reach active feeding lanes throughout the week.
