River Description

This run lies in a beautiful corner of the Uintas that substantially less crowded than popular Mirror Lake Highway region to the north. The run is a 5 miles stretch through a spectacular moutain canyon. Put in below the dam. There are parkig areas on river left before the road climbs to the reservoir or on the river right at the trail head. (Note, the trailhead and campground remain closed until June 30 due to rock fall concerns.) The river is immediately swift below putting on. After a straight section, you'll come to a steeper drop that turns left, then a sharp right. Gary Nichol's warns that the river left wall is undercut. The two class IV drops lie below here. You'll not be able to see them from the road, so either scout from shore, or keep the next downstream eddy in site. Wood from the numerous avalanche paths can collect anywhere along the run. After this the river mellows to swift class 3. Make sure to take out at the first bridge to come to.

Also, do not plan on paddling onto the reservation. I recently spoke with two tribal members who urged me to remind paddlers that we are not permited in the river flowing through their land. Please be aware of the reservation boundry and respect it. That same goes for the numerous dirt tracks that leave the paved road. Unless you're north of the National Forest Boundry, don't leave the paved road. (Most of these tracks are well marked as being for tribal members only.)

There are two ways to access Upper Stillwater Dam. The easiest is from the South. Make your way to Mountain Home Utah, and tun left (west) at the gas station (2 pumps) general store. The road goes to the dam.

If you're coming from Salt Lake, and have a moderate AWD or 4x4, you can take a major short cut up and over Blind Lakes Road off of Rt 35 in Hanna. It's marked with a small FS sign, and leaves 35 just south/east of a white Farm house. The intersection is 42350 West. (The road divides a few pasture and then makes a sharp left. GO SLOW! About 400 yards past here is a 12x12-in ditch all the way across the road. It sneaks up on you, and could rip your front end off.) This road can still be blocked by avalanche debris and snow on the summit, but is generally melted out once the reservoir beings to spill. (Carry a decent shovel, and try not to get stuck, you won't get cell reception up there.) There's plenty of free camping along this road on the north/eastern side of the pass.

I paddled, starting midway down this run to the reservation boundary at 1,800 cfs in June of 2019. The reservation land begins at the large public fishing ponds along the river. The first couple miles below the dam was solid class V with wood at this level, so I opted to put in at the bottom of that. It was sustained class III water features with class IV risk and maneuvering skills required because of braided channels and fallen trees. Normally this stretch is mostly dewatered to pump water to the Wasatch Front. There is a good tributary that adds water just below the dam. This year was a stellar runoff year and Stillwater Dam was releasing about 200 cfs into the late summer.

Gage Descriptions

The USGS gauge is located much further downstream, and not reflective of the flow found on the run. Essentially, the flow found
in the river is the release (and or spill) from Upper Still Water dam, and the contribution from the South Fork of Rock Creek. One can
get the observed flows from the Central Utah Water Conservation District Site or a more complete picture of what's going on in the
basin from the Colorado Basin River Forecast Center Flows should be above 300 cfs. The river becomes much faster above 800 cfs, and
the two bigger drops pack a bigger punch.

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.

Support Wild and Scenic Rivers in Utah

Kevin Colburn

The US Forest Service is conducting a statewide suitability study to determine which of the outstanding rivers in Utah’s National Forests should be protected as Wild and Scenic Rivers.  The Forest Service is recommending that 24 of the 86 rivers that have been identified as eligible for designation should be formally recommended for Wild and Scenicdesignation.  Let them know what you think by February 15th.
