Green River Spillway
Cold, clear tailwater below Flaming Gorge — four stretches, one corridor, pick your water.
The Green below Flaming Gorge Dam is tailwater — cold, clear, and running on the dam's schedule, which is what makes it one of the West's great trout fisheries. Four stretches share the corridor: the A Section's canyon drift from the spillway, the quieter B and C Sections, and the long open miles of Browns Park. Most stretches float in a day; Browns Park takes two or three, and all four link to the Gates of Lodore.

All four stretches, spillway to Lodore — the whole tailwater in one float.
A Section
Spillway to Little Hole: the classic day float through Red Canyon below Flaming Gorge Dam. Seven miles of cold, clear tailwater between red quartzite walls of the Uinta Mountain Group, with Blue-Ribbon trout water the whole way.

- Little Hole
B Section
The B Section on its own: Little Hole down to the Indian Crossing ramp, where the Green leaves Red Canyon and opens into upper Browns Park. Fewer anglers than the A Section above, because the only ways in are by boat or a long gravel road, and bigger fish, the twenty-five-inch browns the section is known for.
Steady tailwater current, riffles at Washboard, and Red Creek Rapid halfway down, Class III and the hardest water on the reach, which the BLM advises looking at before running. Cottonwood camps along the way, and no float permit. Dam-release water runs cold year-round here, so dress for immersion.

C Section
Indian Crossing through Swallow Canyon to the ramp at the canyon's east exit: the C Section, cold clear dam-release water across Browns Park’s open valley, the walls closing in only near the end, with mellow riffles, osprey on the cliffs, and the big browns of Browns Park.
No launch permit. Utah requires everyone to wear a non-inflatable life jacket from Indian Crossing to 100 yards below Taylor Flat Bridge, and at 4,500 cfs or more the bridge is too low to float under; use the Bridge Hollow ramp above it. Regulated flow means the run is consistent all season where snowmelt rivers are not; the water is cold regardless. A day trip for most parties, or an overnight at one of the camps along the canyon. Both ramps are reached by dirt through Browns Park.

A + B Day Float
A and B back to back: launch below the dam, drift Red Canyon's quartzite walls to Little Hole, and keep going past the crowds into the open valley at Indian Crossing. Commonly floated in one long day, with the morning in the canyon and the afternoon in Browns Park. No float permit; the NRA entrance fee applies at the top. Dam releases change through the day with power generation, so check the schedule before you launch, and expect cold water start to finish.

A + B + C
The whole lettered corridor in one run: A out of Red Canyon below the dam to Little Hole, B past the crowds into the open valley at Indian Crossing, then C through Swallow Canyon to the ramp at its east exit. Cold dam-release water the whole way — regulated by dam operations rather than snowmelt, so it runs consistent when snowmelt rivers do not. Mellow riffles, osprey on the cliffs, and the big browns of Browns Park.
No launch permit; the NRA entrance fee applies at the top. Utah requires everyone to wear a non-inflatable life jacket from Indian Crossing to 100 yards below Taylor Flat Bridge, and at 4,500 cfs or more the bridge is too low to float under; use the Bridge Hollow ramp above it. The Swallow Canyon ramp is reached by dirt through Browns Park, which is the one thing here that weather can change.

Browns Park
Browns Park on its own: from the Swallow Canyon ramp through the wide valley of cottonwood groves, wetlands, and open range where the Wild Bunch wintered, to the put-in at the foot of the Gates of Lodore. Class I flatwater, rich with wildlife, and the most abrupt transition on the Green: open sky and sage flats, then vertical red walls.
No permit to float the park; the Gates of Lodore is an NPS lottery put-in, so this route ends where the permit system begins. On the refuge, camping is only at the designated sites in the Crook and Swinging Bridge campgrounds. The shuttle is dirt through the park, high clearance after weather. Two or three easy days for a family or a canoer.

Full Corridor
Launch at the base of the Flaming Gorge Dam through Red Canyon to Little Hole, the B Section's big-fish water to Indian Crossing, Swallow Canyon, and then Browns Park all the way to the Gates of Lodore.
Four sections, no float permit on any of them, and cold, dam-regulated water the entire way, so the trip runs in summer when the snowmelt rivers are dropping. Plan it as a multi-day with camps in the B Section, Swallow Canyon, and the park. It ends at the Lodore put-in, where the NPS permit system begins; a party with a Lodore lottery date can treat this as the approach and launch into the canyon with the river already under them.
