Green River — below Fontenelle
Tailwater below Fontenelle Reservoir; verify releases and access.
Wyoming · public-access reaches. This page is what the desk knows about the water itself. What it is doing today — flow, water temperature, weather, and the hazards those produce — is a reading with a date on it, and it lives in Trip Prep.

These links were checked against the live agency site on 2026-09-01. Rules for a water change inside a season, so the agency’s own page on the day you go is the only current answer — this desk does not hold one.
Directory review
Review provenance unavailable
The fleet directory holds no record by this name in Wyoming, so there is no directory review to show.

How access works here
Access concentrated below the dam
On a tailwater, public access clusters below the dam and thins downstream. The outlet reach is usually the busiest water on the river and the most exposed to a release.
Launch · There is usually a ramp near the outlet. Launching and taking out on a tailwater is a timing problem as much as a facilities problem — know the generation schedule first.
Parking · Outlet parking fills early on weekends and holidays. Have a second access point in mind before you leave home.
Wyoming publishes public fishing areas and walk-in areas; much of the state's river frontage is private, so the walk-in and public-area list is the thing to check, not the map generally.
Gauge
A public gauge is mapped
Flow and water temperature for this water are read from USGS site 09211200, Green River below Fontenelle Reservoir, WY. It is an official public gauge, not a fishing pin: it describes the river at one point, and the reach you stand in may be doing something else.
