The Green River below Flaming Gorge Dam in Dutch John, Utah, offers a classic tailwater fishery with crystal-clear waters, deep runs, and abundant trout in a stunning canyon setting.
Overall Fishing Conditions
- Conditions are rated 9 out of 10, excellent for trout fishing due to the ideal water temperature around 57°F and normal flows that support active fish behavior without the challenges of high water or extreme heat.
Insect Hatches and Their Timing
- Expect increased activity from midges and blue-winged olives in the late morning and early afternoon, spurred by the mild temperatures and partly sunny forecast that could trigger sporadic hatches during isolated showers.
- Terrestrials like ants or beetles may appear near the banks in the evening as winds subside, providing opportunistic feeding windows.
Species to Target
- Focus on rainbow and brown trout, which are highly active in the fall with the cooling waters and stable flows encouraging them to feed aggressively in deeper pools and riffles.
Top 5 Fly Patterns to Use
- Parachute Adams for versatile dry-fly action on surface feeders.
- RS2 as a reliable nymph pattern for subsurface imitations.
- Zebra Midge to match the prevalent midge hatches in slower waters.
- Pheasant Tail nymph for drifting through runs where trout are holding steady.
- Elk Hair Caddis for evening caddis emergences along the faster currents.
Best Times of Day to Fish
- Target early morning around sunrise for the best hatches and less angling pressure, with the waning crescent moon enhancing low-light feeding.
- Fish late afternoon into dusk when the water warms slightly and insects become more active, making for prime top-water opportunities before potential evening showers.
