River Description

One of the more scenic rivers in northern Utah, class II - III- with some wood avoidance, ~9 miles. Beautiful. Ideal for inflatables and light weight kayaks. Two mandatory portages. Several runnable drops. Ideal level 600 cfs, runnable down to ~450, 1000+ cfs is scary.  

Access is an issue.  Although unsigned, there is a DNR river access through the Aspen Acres (Shoshone Rd) green gate.  Park in the large dirt pull out on the north side of the road and hike down to the river.  This launch is just above where Smith and Morehouse enters and increases the size of the Weber. The New Lane Rd takeout is just downstream from a dam that diverts ~3/4 of the river into a canal.

Was on this section on 5/19/20, portaged one low bridge- and all of the diversion dams at higher (1000+) water level. Following previous comments, below or at Smith and Morehouse is mandatory for putting in, there are still 5 to 6 fences below Aspen Acres until right above the SM confluence. It is confusing and dangerous, because with all the "do not trespass" signs everywhere Aspen Acres is the only clear river access point that is marked. Interested to see if anyone is working on this access issue?

Ran this on May 2, 2020 around 500 cfs. We put in about a mile downstream of the Smith and Morehouse confluence after running into a landowner and obtaining permission. There were no barbed wire fences. There are a two diversion dam drops after you exit the canyon and get close to Oakley. All runnable at this level (class 3 ish). There was one obvious and easy tree portage less than a mile from the takeout, then the final diversion dam portage. Very pretty run, especially the middle section through the forest.

Currently 1 barbed wire fence down between Aspen Acres put in and the NSF campground take out. Bridge portage at RR ranch area. River in good shape.

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.
