River Description

This is a rather long stretch, about 8 miles, and can take quite a while at lower flows when its not moving fast. Putin below the Eggs takeout dam, for the full stretch. This dam is much safer than it used to be after it was reworked, which reduced the dangeous hydraulic, but you will still want to stay away from the dam hydraulic.

There can be heavy wood load on this stretch. 

There are some fun wave trains below the I-84 on ramp bridge, which are almost-good surf waves, and can be caught at some flows. 1500-1700 has some fun wave trains. At the higher flows seen in 2011 (3000-4000+cfs), the river becomes so wide its hard to find the main channel, and gravel bars and log jams can move and change quickly. 

The Unita bridge signals the main drop of this run, which is an unfortunate jumble of concrete rubble (the story goes that this was dumped in the river on purpose to keep kids from jumping off the bridge). This is a possible putin as well. Be careful where you park, and respect the abundance of no trespassing signs. 

After the Uinta drop there are many class 2 meanders. 

 A footbridge over the river signals the approach of Slide One, which is usually good to go on the right. A little bumpy at 350cfs. At higher flows look for a surf wave across the top of this slide. 

Slide Two follows shortly thereafter. This is a much steeper slide, and is probably the crux of the run. Wood has accumulated on this drop before, and a road scout or bank scout might we worthwhile.  This drop is really fun once it pads out more. If you wanted to try out your kayak backpack, you could hike up the bike trail to these slides from the Riverdale disc golf course parking. 

The disc golf course parking is another possible putin for a short run, and there is a little front surf wave just upstream from this parking area. Below the next bridge is a 3/4 riverwide tree that has fallen in on the right in 2014, with room on the left. That fallen tree marks the high point of an attainment section at lower flows. 

The Riverdale Wave, or the Riverdale drops (since the wave broke in 2011), is still a highlight of the run, with pushy ferries and swirlies below the first drop, in a pool that is nice and deep in most areas, very good for swirlly roll practice. The former wave can still be surfable at some flows in a fast boat, and a second wave sometimes forms.

A fun drop; one of the biggest waves around in the 2011 flows (above 3000).

The drop is immediately after the bridge. This drop can accumulate wood at any point along its crest. It is advisable to scout this drop from the bridge or river right prior to running. 
 As of May 2019,  the debris that had obscured the left side has blown out and now the flow and main line cuts sharply from mid-left to center.

3 new river-wide trees as of 6/1/19. The first is 100 yards above the Uintah bridge. Eddy and portage river right. The other new trees are in the long, flat section between the toll road bridge and the powerlines. There is plenty of time to see these coming and both can be portaged on river right.

There is a gauge right at the put in for this run that should give a more accurate flow.,00060,62614,00010,00095,00400,00300,00045. We ran this section on Aug 5,2017 and the flow here showed 377cfs, but I missed the disclaimer about the ~300cfs difference. We effectively ran this (in recreational kayaks) at 136cfs thinking it was 377cfs. We scraped along pretty much most of the way until we got past the Uinta bridge. Below that was better. There were 3 places we had to take out to get around log jams. We continued all the way to 24th Street in Ogden. All in all it was an 11 mile run. It was still fun, just be sure to check the proper gauge before deciding to do this run.

Gage Descriptions

The ~300 cfs diverted at the Mountain Green rest area dam is put back in at the power plant. There is another diversion at the power plant, and another at the Eggs takeout dam, so the exact flow is not known for this reach.
2016-04-20: There is a new USGS gauge which should be accurate for this stretch!

Directions Description

The putin is on private land, and occasionally has been closed due to construction. Another putin is immediately off of Rt 89.

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.
