SEASON: Seldom runnable, but keep an eye on the gauge during late
May to June.
FUN FACT: The best way to experience the San Rafael Swell.
ACCESS: The long run (3 days) starts at the Highway I-70 bridge
across Muddy Creek less than a mile east of exit 97. Alternative access
points exist at Lone Tree Crossing, Tomisch Butte, Chimney Canyon, Salt
Wash, and the final take-out at the Highway 24 bridge in Hanksville. Keep
in mind that your shuttle can take several hours.
DESCRIPTION: Muddy Creek can be boated as a multiday trip, but
The Chute is often boated as a day trip.
Starting from I-70 Muddy Creek flows through ranch land as it cuts a
course across the desert. This first 11 mile section contains some class
The next section starts at Lone Tree Crossing. This infrequently
boated section has some great camping along the river as the river
begins to cut a course through the impressive geology of the San Rafael
Swell. There are few rapids in this 19 mile class I/II section.
The most popular section begins at Tomisch Butte. It's a long drive
from Highway I-70 exit 129. Follow the frontage road as it heads west
along the south side of I-70 and make sure you have a good map. There
is camping at the put-in and in the rare years when flows are good
floaters gather to paddle this 15 mile section that includes The Chute.
There are a few class II rapids along this section until you enter The
Chute which is a very impressive canyon up to 300' deep and only 7' wide
in places. This narrow box canyon is approximately 4 miles. There is an
access point at the end of this section at the Chimney Canyon trailhead
near the Hidden Splendor Mine.
Once you leave the access at the Chimney Canyon trailhead you will
leave the day trippers behind. It's another 5 miles of class I/II water to an
access point downstream from Salt Wash where a spur road off Highway
24 ends at the river.
The final 22 miles is class I that cuts across the desert.

The Bureau of Land Management is considering the potential for oil shale and tar sands development on 2,431,000 acres of public land in Utah, Wyoming and Colorado. This development could threaten the quality of paddling experiences including the multi-day desert floats on Desolation and Grays Canyons of the Green as well as the adventure available for kayaks and packrafts to explore the San Rafael, Muddy and Escalante. American Whitewater partnered with our colleagues in the Outdoor Alliance to highlight the value of these areas for outdoor recreation.
Washington, DC – Today, Senator Orrin Hatch (R-UT) and Representative John Curtis (UT-3) introduced the Emery County Public Land Management Act of 2018, a historic conservation bill protecting over one million acres of public land, and 98 miles of Wilderness and Wild & Scenic Rivers in Utah’s Emery County. American Whitewater worked to ensure that the Green River, Muddy Creek, and the San Rafael are protected under the legislation.
American Whitewater staff traveled to Green River, UT in late March to meet with private water users and state agencies, and to participate in the official opening of the new boat passage through the Green River Diversion (Tusher Dam). Completion of the boat passage has freed the Green River from its last in-stream obstruction between the Flaming Gorge Dam and the confluence with the Colorado River – over 400 floatable river miles through iconic canyons and historic landmarks. It has a been a long process, and our work isn’t over yet! As your boating representative, American Whitewater will continue to work closely with the dam operators and Utah’s Division of State Lands (FFSL) to ensure that the boat passage meets the needs of the public during its inaugural year.

runs to the inventory!
