Should I go fishing?
Go with caution.
Flow is high for this time of year.
Best option: Floating. A float can fit better than wading only if launches, shuttle, boat skill, wind, and local rules all check out.

Why this recommendation?
USGS shows 2,180 cfs. The flow has been falling about 24% over about 6 hours. USGS marks this reading provisional and may revise it. USGS records for this date (1964-2025, 62 readings) show a median near 1,740 cfs and the upper quartile near 2,060 cfs; today's flow is high for the date. Fishable water may exist, but do not rate it highly without a safe access, clarity, and wading or boat plan.

If you go
- Check first
- RiverReports and USGS Greendale flow are the live checks for this report.
- Try
- Build the day around the section, not just the fly pattern.
- Leave when
- Skip the day when canyon wind ruins line control, when flows and boat traffic make your chosen section crowded or unsafe, when shuttle or takeout logistics are uncertain, or when you would be forcing a long float without a clean exit plan.

Methods, fish species and trip notes
How to fish Green River today.
The Green fishes best when flows are stable, wind is manageable, and the plan fits the section. Clear water rewards long leaders, smaller flies, and patient presentations.
Stable low to moderate flow
Use long leaders, small nymphs, dries, and sight-fishing discipline.
Higher release
Focus on banks, soft edges, streamer lines, and boat-based tactics.
Windy days
Shorten casts, use heavier dry-dropper rigs, or pick protected sections.
Clear sun
Expect spooky fish and strong sight-fishing pressure.
Wading, bank fishing or floating?
Best access methodFloating
These scores compare the risks of wading, bank fishing, and floating.
Wading44/100
Wading is the most sensitive plan today. Use protected edges only, avoid crossings, and downgrade quickly if clarity or current feels wrong.
Bank fishingNot recommended
This report does not recommend bank fishing on this reach.
Floating · Best fit68/100
A float can fit better than wading only if launches, shuttle, boat skill, wind, and local rules all check out.

Is Green River worth the trip today? Check flow, weather, hatches, access, and rules for Utah before you go.
The Green below Flaming Gorge is a clear tailwater where flow, section, boat traffic, and wind decide tactics. Use the Greendale gauge, then pick a realistic wade or float plan.
Fishing words used on this page
- U.S. Geological Survey (USGS) gauge
- A USGS gauge is an official river station that measures flow or water height.
- Cubic feet per second (cfs)
- Cubic feet per second, or cfs, shows how much water passes the gauge each second.
- Technical fishing
- Technical fishing means the fish are hard to fool, so careful casts and natural drifts matter.
- Nymph
- A nymph is a young water insect. Anglers also use the word for a fly that copies it.
- Presentation
- Presentation means how you cast and move the fly so it looks natural to a fish.
- Blue-winged olive (BWO)
- Blue-winged olives, or BWOs, are small mayflies that often hatch in cool or cloudy weather.
- Caddis
- Caddis are small water insects. The adults look a little like tiny moths.
- Dry-dropper
- A dry-dropper rig has a floating fly with an underwater fly tied below it.
- Emerger
- An emerger copies an insect as it rises from below the water toward the surface.
- Indicator
- An indicator is a small floating marker that can show when a fish takes an underwater fly.
Why this call
Why this score
FlowUse caution
USGS shows 2,180 cfs. The flow has been falling about 24% over about 6 hours. USGS marks this reading provisional and may revise it. USGS records for this date (1964-2025, 62 readings) show a median near 1,740 cfs and the upper quartile near 2,060 cfs; today's flow is high for the date. Fishable water may exist, but do not rate it highly without a safe access, clarity, and wading or boat plan.
Best mode nowUse caution
Float: A float can fit better than wading only if launches, shuttle, boat skill, wind, and local rules all check out.
SeasonHelps
Fall: BWOs, midges, streamer windows, and cooler weather improve quality.
Water temperatureHelps
USGS water temperature is about 58.6F, and the rolling 24-hour high did not trigger a heat caution. USGS marks the temperature data provisional and may revise it.
Public alertsHelps
No active NWS alert was returned for this forecast point.
Trip notes
Check these before you choose a reach.
Use the Greendale trend more than a single magic number. Stable releases are the best all-around trout window. Higher or changing releases usually push the plan toward banks, streamer lanes, or a float with solid shuttle logistics.
Skip the day when canyon wind ruins line control, when flows and boat traffic make your chosen section crowded or unsafe, when shuttle or takeout logistics are uncertain, or when you would be forcing a long float without a clean exit plan.
Start by matching section to day length: A Section for shorter wade-focused trips, Little Hole as a key access and takeout checkpoint, and B or C only when the weather, crew, and shuttle all support a longer canyon commitment.
If Green River wind, crowding, or shuttle logistics look wrong, pivot to the Duchesne for a freestone-style trout day or to the Provo when you want a different Utah technical-trout plan closer to Wasatch services.

Before you go
Check Utah DWR rules, Fish Utah, current emergency changes, and any Flaming Gorge or Green River section-specific rules before fishing.
Where to access the river
Flaming Gorge Dam and A Section
The best-known clear tailwater reach and a common starting point.
Little Hole
Important takeout and access context. Verify current status and fees.
B and C sections
Longer floats with more shuttle and weather exposure.
- Wind and remote canyon logistics can make a good flow day hard.
- Boat traffic, wading pressure, and guide use are normal on this river.
- Verify permits, launches, shuttles, and current Utah rules before the trip.

Quick questions
What should I check first before fishing Green River?
Check RiverReports or USGS 09234500, dam release context, weather, wind, Utah rules, and shuttle status.
Where should a first-time visitor start on Green River?
First-time visitors usually orient around the Flaming Gorge tailwater and A Section, then decide whether to wade or float.
Can I wade Green River?
Yes in some areas, especially at manageable flows, but many anglers use boats and shuttles.
What flies should I bring for Green River?
Bring the seasonal fly box, then adjust size, weight, and color to the water level, clarity, temperature, and fishing pressure you find.
