Access map
Put-in
Spillway Boat Launch Area below Flaming Gorge DamBoth endpoints are Ashley National Forest / Flaming Gorge National Recreation Area boat-launch facilities with published coordinates and fee/pass requirements.
Take-out
Little Hole Boat Launch AreaSpillway can be very busy with commercial drift boats and has a long, steep stair/carry between parking and the launch area. Do not block the ramp while rigging.
Road shuttle
Stage the take-out at Little Hole, then drive back to the Spillway Boat Launch below Flaming Gorge Dam. Local outfitters commonly support shuttles, but private groups should still verify ramp access, pass requirements, and vehicle logistics before launching.
Additional access notes
- Little Hole has multiple ramps, restrooms, picnic areas, and potable water seasonally, but busy fishing days can make landing and loading slow.
- Utah DWR stream-access guidance was rechecked for this run. Stay with the public launches, trail corridor, and legal public stops; do not assume private-bank access away from the managed corridor.
More route and safety guidance
- Check USGS 09234500 and the current Flaming Gorge release schedule immediately before launching. Reclamation says the 2026 release plan can fluctuate hourly and change with river conditions or forecasts.
- The 1,000 cfs value is only a conservative runnable minimum, not an ideal range or high-water clearance. During elevated releases, Reclamation warns that the below-dam river can run colder, higher, and swifter.
