Green River Diversion Structure

In late March 2017, American Whitewater celebrated the official opening of boat passage through the Tusher Diversion Dam on the Green River near Green River, UT. Completion of the boat passage has freed the Green River from its last in-stream obstruction between the Flaming Gorge Dam and the confluence [...]Read More

Green River (WY/UT/CO)

American Whitewater is working to protect the Green River—one of the West’s most iconic and ecologically significant rivers—from harmful water diversions and to ensure its long-term protection under the Wild and Scenic Rivers Act. Flowing from Wyoming’s high plains through Utah’s canyon country before joining the Colorado River, the [...]Read More


River Description

The Green River’s passage through Desolation and Gray Canyons offers one of the West’s most classic multiday float trips—a journey of 80 miles or more through a remote, strikingly beautiful landscape, steeped in history and rich in natural character. Though often overshadowed by more famous whitewater stretches in the Southwest, this section of the Green is a hidden gem prized for its accessible Class II and III rapids, lush riverbanks, fascinating archeological sites, and the serene solitude that canyon country delivers best. Whether you're a first-time rafter or seasoned boater seeking a more relaxed pace, Deso–Gray has something for everyone.

Trips most commonly begin at Sand Wash, a remote put-in accessible via dirt road, where all groups must check in with Bureau of Land Management rangers. While some boaters choose to float a longer stretch beginning upstream at Ouray, launching from Sand Wash avoids the long 40-mile flatwater lead-in and places you immediately at the doorstep of Desolation Canyon proper. Here, the canyon walls gradually rise as you paddle downstream, closing in to heights of more than 5,000 feet above the river, making this one of the deepest canyons in North America.

Desolation Canyon earns its name not from a lack of beauty but from its vast remoteness. Despite its isolation, the canyon is alive with greenery and has consistent flows as a result of controlled releases from upstream dams. Dense tamarisk and willow crowd the banks, making shoreline landings tricky in some areas—especially at high water when brush and current conspire to make camps hard to reach. In contrast, low water reveals ample sandbars and beaches ideal for camping and lounging. Wildlife abounds in this corridor, with frequent sightings of bighorn sheep, beaver, and an impressive variety of birds, including peregrine falcons and great blue herons.

The rapids on this stretch are mostly mellow, with the majority falling into the Class I and II category

Wildlife Refuge launch area

Distance: 0 mi
Access Point
Wildlife Refuge launch area

This boat ramp adds 6 or 7 miles of scenic flatwater compared to launching at the bridge in Ouray. In the evening we did hear the bugleing of elks, so that was nice. From highway 88 turn east and north on Wildlife Refuge road till you come to the river and a fairly obvious area with dirt ramps down to the water.

Ouray Bridge boat ramp

Distance: 7.05 mi
Access Point
Ouray Bridge boat ramp

There are large parking areas and boat ramps on river left at the highway 88 bridge, on both upstream and downstream sides.

This is the standard put-in location for multi-day river trips. All boaters must get their permits checked by the ranger here.

Start of Uintah and Ouray Reservation, River Left

Distance: 44.46 mi
Other

For the next approximately 60 miles, down to the Coal Creek confluence, the land on river left is part of the Uintah and Ouray Reservation and managed by the Ute Indian Tribe. While recreational permits were available, the tribe suspended all recreational permits for non-tribal members due to repeated violations. This restriction is currently indefinite and prohibits all camping, hiking, or firewood gathering on tribal land.

Joe Hutch Rapid

Rapid
Joe Hutch Rapid

This is the most notorious rapid in Desolation Canyon, transformed dramatically after a massive debris flow from Joe Hutch Creek in 2008. At high water (20,000–25,000+ cfs), this becomes a full Class IV with significant hazards. A strainer lurks on river right, a powerful hole dominates the centerline, and a towering wavetrain builds on river left—the third wave is capable of flipping large rafts. The preferred line is to enter left, then pull hard right just below the first wave to avoid the largest features. Scout from river right as soon as the creek and strainer come into view. Swimmers risk being pushed into traps along the left wall, especially at high flows, so set safety with throw ropes and chase boats on river left (the only feasible rescue side). Avoid the center-left eddy mid-rapid—it’s an escape-proof trap at high water. At low flows (5,000 cfs and below), Joe Hutch drops to a Class III but still demands respect. The entrance chute appears narrow but is wider than it looks—enter left of “Golf Ball Rock”, steer clear of sharp rocks on river left, and avoid the hole near the bottom right before the wall. Traps are less dangerous but still present. Safety and scouting remain essential at all flows.

Wire Fence Rapid

Class: IIIDistance: 98.08 mi
Rapid
Wire Fence Rapid

Wire Fence is a long, fast, and read-and-run Class III, often underestimated. Though technically straightforward, it has claimed lives—one fatality occurred in 2011—so give it the attention it deserves. At high flows, this rapid washes out slightly but maintains a powerful current and strong hydraulic at the bottom. Stay alert for a left-side line to skirt the worst of the final hole. At lower flows, it becomes more defined. The drop is steeper and the bottom hole more pronounced. Stay left, keep your boat square, and expect a fun but punchy ride. It's a fast swim if you go in, and fairly forgiving compared to Joe Hut.

Three Fords Rapid

Class: IIIDistance: 98.45 mi (approx.)
Rapid
Three Fords Rapid

Three Fords is arguably the most complex rapid on the river at low water, and a solid Class III at high flows. At flows below 10,000 cfs, it becomes a technical and demanding rapid—scouting from river right is strongly advised. Multiple large boulders create steep pour-overs, holes, and tight lines, especially near the center. Avoid the middle of the river entirely—it hides traps not visible from upstream. At lower flows, the easier sneak line on river left often disappears, forcing boaters to commit to the 'hero line' on river right: a series of drops and big, closely spaced holes. The current pulls deceptively right at the entrance, so boaters must set up early and stay on line. This is a long swim if you flip, with several features stacked in succession. At high water, the holes smooth out and the rapid becomes a fun, wavey Class III+. The sneak line on the far left is typically open up to 10–12K cfs. Small craft may be able to line or portage river left.

Coal Creek Rapid

Class: IIDistance: 108.23 mi
Rapid

Coal Canyon is a straightforward, fast-moving Class III with a series of large waves and a few mid-channel holes. It tends to be steep and splashy, but relatively forgiving. The challenge here lies in reading the water on the fly—there’s little time to line up between features. At high flows, the holes become bigger, but the rapid remains boatable for most groups with competent paddlers. Read-and-run, staying center or slightly left, and be prepared for sudden laterals. At low flows, more rocks begin to show, and some of the holes become tighter. Expect a steeper profile and more maneuvering through slots. Keep an eye out for “sneaker rocks” that can pin or wrap boats. The confluence of Coal Creek marks the end of the Uintah and Ouray Reservation and camping is available on river left from this point downstream.

Boat Ramp below Swaseys

Access Point
Boat Ramp below Swaseys

This large and paved boat ramp is a standard take out. The ramp is obvious on river left as you exit Swaseys rapid. Long term parking is in a separate area about 100 yards down the road.

Tusher Dam

Distance: 126.46 mi
Hazard

The boat passage through Tusher Dam on the Green River opened in March 2017, thanks to advocacy by American Whitewater. Located ~6 miles upstream of the Town of Green River, between Swasey’s Boat Ramp and Green River State Park Campground, the diversion allows safe boat passage. The chute is in river center to improve navigation at low flows. Warning signs at Swasey’s and 300 feet upstream of the portage trail mark the boat passage (CENTER OF DIVERSION) and portage trail (RIVER LEFT). If closed, signs read: “CAUTION Boat Chute Closed Use Portage Trail.” The trail and emergency landing are ~300 feet upstream on RIVER LEFT, following a 15-foot-wide maintained two-track road. The chute is between two indicator boulders and works best at flows above 1,300 cfs. At high water, the boulders may be submerged. Scouting is recommended before continuing downstream.

Not sure how to upload files, so here it is in text. I copied and edited Karen's GPS positions into a Google Earth .kml file. Copy and paste below into a text document, name it something like Deso_Gray.kml (ie Notepad, Wordpad), and open in Google Earth to see the put in, and rapid locations. Might have to reformat some of the longer lines.
