Green River Fishing Report - 2025-11-14

River Description

The Green River below Flaming Gorge Dam in Dutch John, Daggett County, Utah, is a premier tailwater fishery renowned for its abundant rainbow and brown trout populations. Current conditions show stable but below-average flows at 847 cfs near Greendale (-34% vs. historical average), with gage height at 8.18 ft, creating clear, wadeable sections ideal for precise presentations. Water temperature sits at a chilly 47.5°F (-13% vs. average), which slows metabolic rates in fish but maintains oxygen levels for active holding in deeper runs and riffles. Recent partly sunny weather with SSE winds at 10-15 mph has kept visibility high, though low humidity (45%) and a dew point of 24°F suggest crisp, comfortable days for anglers. Lunar conditions feature a waning crescent moon at 26% illumination (last quarter on Nov. 12), with moonrise at 3:39 AM and set at 4:23 PM, minimally impacting daytime fishing but potentially enhancing low-light bites near dawn or dusk. Overall, this is a technical nymphing river with moderate flows favoring subsurface tactics, though dry fly opportunities may emerge in sunnier pockets; fishing potential is solid for selective trout in the A, B, and C sections.

3-Day Forecast

Forecast data is limited to the immediate period; expect continued mild fall patterns with minimal precipitation based on National Weather Service trends. Friday (today): Partly sunny skies with highs of 61°F and lows near 38°F, SSE winds 10-15 mph—improving visibility for sight fishing and nymphing while moderate temps could trigger subtle mid-day hatches. Saturday and Sunday: No specific forecast available, but yesterday's high of 64°F and no rain suggest stable, partly cloudy conditions persisting with highs in the low 60s and light winds; cooling evenings may concentrate fish in slower tailouts, boosting nymph success but requiring caution for potential frost.

Fishing Outlook

Fair overall for fly fishing success, with conditions supporting consistent catches for patient anglers but limited by cooler water and reduced insect activity in mid-November. Stable below-average flows (847 cfs) allow easy wading and access to prime trout lies without excessive current, reducing fatigue during long drifts. Cool water temps (47.5°F) keep fish sluggish but predictable in deeper pools, favoring nymphing over surface action, while partly sunny weather enhances angler comfort and spot visibility. Waning lunar phase offers neutral influence, with low illumination potentially aiding stealthy approaches during overcast moments; expect 1-2 fish per hour in riffles, improving near campgrounds.

Recommendations

• Flies & Techniques: Focus on subsurface presentations for rainbows and browns holding in current seams—try a Pheasant Tail Nymph (#16-18) or Prince Nymph (#14) dead-drifted under an indicator for consistent takes in moderate flows; add a Zebra Midge (#18 black) as a dropper for finicky fish in cooler water. If subtle hatches appear (e.g., midges or BWOs), switch to dry-dropper rigs with a Parachute Adams (#16) on top. Euro-nymphing excels in low flows for precise depth control.
• Best Times & Tips: Target dawn (6-9 AM) and late afternoon (3-6 PM) windows when low light and cooling temps position fish aggressively; avoid midday lulls if winds pick up. Wading is safe with current gage heights, but watch for slippery rocks in riffles—wear cleats and check for rising levels from upstream releases. No major weather risks, but layer for dropping temps below 40°F at night; respect catch-and-release in A-section to preserve the fishery.
• Gear Notes: A 5- or 6-weight rod (9 ft) pairs well with a 5X tapered leader for delicate turns in clear water; bring a strike indicator kit and split shot for nymph depth adjustments. Pack thermals for comfort in 45% humidity.
