Green River Below Fontenelle Reservoir

A decision-first Fontenelle tailwater report: check the exact release trend, confirm legal access and seasonal restrictions, then choose a bank, wade, or float plan that fits the water you find.

Recommended approachBank / edge

Mode scores adjust the river-wide score for the risks of wading, bank fishing, or floating.

Wade4/100

Wading is the most sensitive plan today. Use protected edges only, avoid crossings, and downgrade quickly if clarity or current feels wrong.

Bank / edge · Best fit21/100

Bank and edge fishing is the safer default when water is high, pushy, or not fully verified.

Float19/100

A float can fit better than wading only if launches, shuttle, boat skill, wind, and local rules all check out.

River strategy

Check the release trend before choosing how much river to cover.

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.

  • Use USGS 09211200 for the machine-readable flow that feeds the fishability decision on this page.
  • Treat a sharp rise or fall as a reason to simplify the plan and stay off uncertain crossings.
  • Use the BLM Tailrace Camp Area as a verified public starting point, not as permission to cross neighboring private land.
  • The first mile below the dam closes October 1-December 31; the separate trophy rule begins 4.5 miles below the dam at County Road 8.

FlowUse caution

USGS shows 725 cfs with a stable over about 6 hours trend. same-date USGS history (1964-2025, 62 readings) puts normal around 1,380 cfs and the lower quartile near 1,070 cfs; today's flow is below normal for the date. This is below normal, so edge depth, temperature, and pressure matter.

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.

SeasonHelps score

Summer: PMDs, caddis, terrestrials, and evening activity improve when releases remain stable.

Read the water

What changes the plan.

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 reach-specific heat advisory should narrow or stop only the part of the plan they actually cover.

01

Stable release

Fish defined seams with small nymphs, dry-dropper rigs, and dries when adults are visible.

02

Rising release

Step back from crossings, fish softer banks, and wait for the new level to stabilize.

03

Falling release

Expect fish to reposition; work remaining depth and avoid stranding a boat or wade route.

04

Severe wind or lightning

Leave exposed water. A favorable flow does not make an open tailwater safe in a storm.

Field plan

Fish it with intention.

Best flows

No single universal discharge is promised. Favor a stable trend that leaves defined edges and safe entries at the exact access you inspect.

When to skip

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 reach-specific advisory.

Local plan

Start at the official tailrace access, inspect clarity and edge speed, then decide whether the day stays local or expands downstream.

Backup water

Use Fontenelle Reservoir or the separate Warren Bridge report when the tailwater's release, wind, or restrictions do not fit the day.

Hatches & flies

Bring a flexible box.

TimingWhat to watchUseful flies
01

Read the release graph before tying a rig; trend direction matters as much as the displayed discharge.

02

Fish the near bank and soft inside water before committing to deeper tailwater current.

03

Use small midges or baetis patterns when the water is clear and fish are pressured.

04

Cover deeper banks with a sparse streamer in low light or modest stain.

05

If releases are moving quickly, keep the plan bank-oriented and avoid long downstream commitments.

Access & responsibility

Know the entry. Know the exit.

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.

01

BLM Tailrace Camp Area

Official public access below Fontenelle Dam with fishing and camping context; verify current site conditions before driving in.

02

Below-dam public corridor

Use signed public entries and current land-status maps; visible banks are not automatically public.

03

Seedskadee refuge float corridor

USFWS documents four ramps, designated roads, non-motorized boating guidance, and named river-mile access points downstream.

Rules and notices

Common questions

Before you leave.

What water does this Green River below Fontenelle report cover?+

The tailwater immediately below Fontenelle Dam and the downstream public-access corridor, not the upper Green at Warren Bridge.

What should I check first before fishing Green River below Fontenelle?+

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.
