River Description

Scott England explored this run via packraft in June 2018, which is a good choice of craft considering it is a 1.9 mile hike from the Rock Creek trailhead to the end of Upper Stillwater Reservoir, 3.5 miles to the East Fork confluence, and another mile to a suggested putin one mile upstream of the East fork confluence (4.5 miles one way). Wood portages are more common above there. 

Scott shared:
I made a very nice descent down Upper Rock Creek at 300 cfs in the High Uinta Wilderness. 6 miles total, 7 wood portages up top, but the bottom 3 or 4 miles were super high quality, with relatively few wood issues. The crux of this run is a mile long stretch of steep class IV enclosed in a box canyon. This would be all class V at twice the flow that I ran it at. I would recommend putting in a mile above the confluence of East Fork of Rock Creek and boating down to the reservoir. This stretch has as high a quality of whitewater as you can find in Utah, and it is a great wilderness adventure. 

Its a pretty steep run, roughly 200 feet per mile, 300 feet per mile crux, with some horizon line scouting, but no falls.

Ashley National Forest (UT) Information Needed

Kevin Colburn

The Ashley National Forest is in the process of updating its land management plan—something that hasn’t happened since 1986. This creates an opportunity to advocate for better protection of streams and rivers across the 1.4 million-acre National Forest, which spans from the Uinta Mountains to Flaming Gorge. Right now, American Whitewater needs your help updating the National Whitewater Inventory to include better information on the rivers within the Ashley National Forest. We ask that paddlers familiar with this area add photos and descriptions to the NWI, check out our recent comments, and consider sending a comment letter to the Forest.

Green River Boat Passage Officially Open! - UT

Kestrel Kunz

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.
