What to know about this notice
The listed advisory begins 4.6 river miles below Fontenelle Dam and is not a statutory whole-river closure.
The agency notice is voluntary and reach-specific. Its missing agency end is preserved; the operational review deadline removes it from the active view unless reverified.
Your plan
Today's Green River Below Fontenelle Reservoir plan.
Fontenelle is a release-controlled tailwater, so the useful question is not whether the Green River is generally fishing well. It is whether the exact below-dam trend is stable, the access you intend to use is open and legal, and the wind or storm risk still leaves a safe plan.
- Check first
- Use USGS 09211200 for the machine-readable flow that feeds the fishability decision on this page.
- Try
- Read the release graph before tying a rig. Trend direction matters as much as the displayed discharge.
- Leave when
- Skip the first mile during the October 1-December 31 closure. Elsewhere skip or narrow the plan for sharp release changes, lightning, unsafe wind, unclear access, or a section-by-section advisory.

How to fish it
How to fish Green River Below Fontenelle Reservoir today.
Stable releases and manageable wind create the cleanest nymph, dry-fly, and streamer windows. Rapid flow changes, severe weather, an annual first-mile closure, or a section-by-section heat advisory should narrow or stop only the part of the plan they actually cover.
Stable release
Fish defined seams with small nymphs, dry-dropper rigs, and dries when adults are visible.
Rising release
Step back from crossings, fish softer banks, and wait for the new level to stabilize.
Falling release
Expect fish to reposition. Work remaining depth and avoid stranding a boat or wade route.
Severe wind or lightning
Leave exposed water. A favorable flow does not make an open tailwater safe in a storm.
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.
- Nymph
- A nymph is a young water insect. Anglers also use the word for a fly that copies it.
- Seam
- A seam is the line where fast and slow water meet.
- 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.
- Confluence
- A confluence is the place where two streams or rivers meet.
- 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.
- Midge
- Midges are tiny flies and a common trout food, especially in cold water.
Why this call
Why this score
FlowUse caution
USGS shows 725 cfs. The flow has been stable 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 1,210 cfs and the lower quartile near 974 cfs; today's flow is below normal for the date. This is below normal, so edge depth, temperature, and pressure matter.
Short-term weatherUse caution
The forecast has storm or heavy-precipitation risk, so timing and access matter more than the score alone.
Local scoring depthUse caution
This page is using baseline river-specific guidance while deeper local scoring is still being reviewed. Use the live sources and local checks before relying on the rating.
Best mode nowUse caution
Wade: Wading is in play only where your chosen access has clear footing, legal entry, and no forced crossings.
SeasonHelps
Summer: PMDs, caddis, terrestrials, and evening activity improve when releases remain stable.
Trip notes
Trip notes
Check these before you choose a reach.
No single universal discharge is promised. Favor a stable trend that leaves defined edges and safe entries at the exact access you inspect.
Skip the first mile during the October 1-December 31 closure. Elsewhere skip or narrow the plan for sharp release changes, lightning, unsafe wind, unclear access, or a section-by-section advisory.
Start at the official tailrace access, inspect clarity and edge speed, then decide whether the day stays local or expands downstream.
Use Fontenelle Reservoir or the separate Warren Bridge report when the tailwater's release, wind, or restrictions do not fit the day.

Access and safety
Green River Below Fontenelle Reservoir access and rules.
Use these places as starting points. Open the access link below and check posted signs before you park or enter. The 2026 rule closes all fishing from Fontenelle Dam downstream about one mile to the USGS cable at Weeping Rocks from October 1-December 31. From County Road 8, 4.5 miles below the dam, to the Big Sandy confluence, the rule is one trout, release all trout under 20 inches, and artificial flies or lures only. The current WGFD brochure and posted signs are the legal authority.
BLM Tailrace Camp Area
Official public access below Fontenelle Dam with fishing and camping context. Verify current site conditions before driving in.
Below-dam public area
Use signed public entries and current land-status maps. Visible banks are not automatically public.
Seedskadee refuge float area
USFWS documents four ramps, designated roads, non-motorized boating guidance, and named river-mile access points downstream.
The Tailrace Camp Area is the clearest official public starting point for this page.
Seedskadee prohibits camping and open fires on refuge land. Use designated upstream BLM campgrounds and current refuge rules.
Some unimproved east-side refuge roads close November 15-March 15, and emergency release pulses can change flow quickly.
Do not cross fences, private roads, or unsigned banks based on a map pin alone.
Confirm road and weather conditions before committing to an isolated downstream shuttle.

Quick answers
Quick Green River Below Fontenelle Reservoir answers.
What water does this Green River below Fontenelle report cover?
The tailwater immediately below Fontenelle Dam and the downstream public-access area, not the upper Green at Warren Bridge.

Start with USGS 09211200, then confirm Wyoming rules, dam-area notices, BLM access, wind, and lightning risk.
Is access straightforward on Green River below Fontenelle?
There is verified BLM tailrace access, but downstream ownership is mixed. Stay with signed public entries and confirmed parcels.
Does the fishability score replace local judgment?
No. Use it as a starting decision, then confirm the source timestamp, official rules, alerts, water temperature, visibility, and conditions at the access you actually plan to use.
