Colorado River Basin Management

The Colorado River has been over-allocated and mismanaged for more than a century. Known as the hardest working river in the western US, the Colorado River flows from Rocky Mountain National Park in Colorado to Mexico where it gets sucked dry before reaching its mouth in the Sea of [...]Read More

Green River (WY/UT/CO)

American Whitewater is working to protect the Green River—one of the West’s most iconic and ecologically significant rivers—from harmful water diversions and to ensure its long-term protection under the Wild and Scenic Rivers Act. Flowing from Wyoming’s high plains through Utah’s canyon country before joining the Colorado River, the [...]Read More


River Description

The Green River is dam controlled and, flow permitting, this beautiful high desert run can coincide nicely with good fishing and jaw-dropping scenes.

While it is only 19 miles to the confluence with the Yampa River at Echo Park, the usual take out at Split Mountain is another 25 miles downstream.  See Green: Echo Park to Split Mountain. The total distance from Lodore to Split Mountain is about 45 miles.

Sitting in the tailwaters of Flaming Gorge Dam, this muddy and sandy bottomed section of river is home to some canyon wren, elk, deer and beaver.

The permit and camping is small scale with +/- 300 permits awarded annually.

The canyon is fragile. The rapids are fun.

Grand sandstone arching walls make the Gates of Lodore a real Western treat.

Hells Half Mile Rapid is a fun rock garden for kayakers.

The Hatch and Belknap families really helped put the Green River on the map and made this section famous with their trips and great guiding service. There are secrets in many places that may be found along with the remnants of the dinosaurs.


River Features

Gates of Lodore Put In

Distance: 0 mi

Hells Half Mile

Class: IIIDistance: 11.71 mi
Rapid
Hells Half Mile

The most challenging rapid on the run. Look for the horizon line at the end of a long pool. Manuver through the boulders at the start to line up for the center slot that feeds into a wave train. Following the entrance, you will need to negotiate another quarter mile of rocks, waves, and holes that slowly tapers off.

Echo Park

Distance: 19.08 mi
Take Out

Multi-day river trips pass by Echo Park but the vehicle-accessible river access here is not available as a put-in or take-out for multi-day river trips except in an emergency situation. The access may be used by packrafters or others crossing the river. You can also stop to refill water bottles or take a hike before continuing your trip down the Green River. The Harpers Corner Road that provides access to Echo Park is typically closed seasonally in the winter and early spring and rainstorms can make the road impassable. Echo Park has a campground with 17 sites available to those who drive in on the road.

I ran this on 6/22 to 6/26 with 2300 on the release from flaming George and 11000 flowing down the Yampa. I think they should rename the Green River the Mosquito River as they were so thick and numerous that literally bug spray helped but did not stop them. We were wearing our cold gear to keep us covered up despite the temps in the 80's. Enjoying a campfire was out of the question. And when the Mosquito's were not eating us the skunks were raiding out food. If you leave food out the skunks will get it. I am not making excuses we should have picked up all our food but just be warned anything left out the skunks will get. Pack it all away. Also just being on the water was not helpful as the Mosquitoes were right there with us floating down the river in the middle of the current. Only in the biggest rapids was this not true. You have been warned. What i said was true for all our campsites Jones Hole 3, Rippling Brook 1 and Pot Creek 2.

GREAT TRIP, put this on your bucket list. Ran this about 1800, March/18, good to go! Did it in 4 days but wish we would have taken 5. Getting the offseason permit was easy, but be prepared for all 4 seasons. Rainy, cold, hot and snowy! Our last day we woke up to around 3 inches of snow on our boat. Purchase yourself a guide book, but at 1800 almost everything was read and run except Hells Half Mile.

At 1800 the move at HHM in an oar rig was start center left, then go left or right around Lucifer rock in the middle of the current. I went right, but had to avoid a guard rock at the top, making the move a little tricky. Luckily, all the rapids at this level were pretty mellow. Not pushy, and not too bony.

For shuttle, River Runners requires a 3 car minimum and in the low season, we were the only trip going so they couldn't shuttle our car. We ended up dropping a bike at the take out, biking to Vernal, Utah and then renting a car at the airport to set shuttle. Definitely a little hairy but doable.

Winnie's Rapid is the first one you'll approach and one of the only rapids where the easiest scout is on the right. The big boulder in the center is the obvious obstacle to avoid. When rowing watch out for shallow rocks on the river right side. Bumping off these rocks will push you onto the big boulder.
On the topo map (Dinosaur National Monument Rivermpas) you'll see an elbow bend in the river before the marking of this rapid on the map. Be sure to catch the eddy on river left in the elbow turn. A trail on river left leads you along the rapid for a good scouting view. The rapid can be run down the center, avoiding the rocks on either side, especially those hiding under the surface on the left. While you're out scouting this rapid, go ahead and scout downstream. While the map makes it seem like there is a distinct distance between Upper Disaster and Lower Disaster there is actually a 'Middle Disaster.' STAY LEFT and READ the WATER! This section is quite technical. Also the right side can be quite dangerous. A group we launched with found trouble at this spot, flipping three oar rigs and landing one of them on a rock for 4 hours. You'll notice there are no pictures for Middle or Lower Disaster. We had good intentions to scout, yet the rapids came upon us before we knew what was really happening.
The map (Dinosaur National Monument Rivermaps) marks a Class III, Harp Falls, before Triplet Falls. However, at this low water level, we never noticed any rapid before Triplet that could be deemed a Class III. You'll see the post for Triplet campsite just before you hear the rapid. As the name indicates, Triplet consists of three drops. Again, this rapid can be scouted river left, and run with a sequence of Center, Right, Left, respective of each drop. The first drop has some sneaky rocks hiding under the surface, but with some good river reading skills a raft should be able the thread the rocks down the middle. The second drop has a beautiful tongue to follow. Move left for the last drop and avoid the rock on river right. The run out for the rapid seems a little shallow. Have your eyes scouting for the best channel to follow.
Third drop + run out.
Winnie's Rapid is the first one you'll approach and one of the only rapids where the easiest scout is on the right. The big boulder in the center is the obvious obstacle to avoid. When rowing watch out for shallow rocks on the river right side. Bumping off these rocks will push you onto the big boulder.
SCOUT on Left. You'll definitely hear the roar of this rapid before seeing the drop. It is the most notable rapid on this section. The scouting trail gives you a great view of the first section of the rapid, but be sure to scout below the bigger part of the drops, as the run gets rocky and the action in the drops happens really fast. The first part of this drop brought the most carnage for our duckies on this trip, 5 of 9 taking a swim on this one. The rafts had exciting runs as they all washed up on Lucifer, the pillow rock after the first drop. When rowing, I found little time to make any move between the first drop and Lucifer. It seems to be a good idea to intentionally ride the pillow rather than to try and avoid it. After Lucifer, the deepest channel was on the left; we know that now after two rafts got hung up on the center rocks in the lower half mile. At even lower water levels, Lucifer is quite mischevious. An OARS guide said that at 600cfs he got his rig pinned there there three hours. Have fun!
Moonshine rapid comes before SOB. It's worth scouting on the left as there are some weird rocks in the last drop that you would want to avoid. But for the most part, the rapid is pretty easy to run, center then right at the end. SOB is a technical little guy, worth a scout (left) mostly to avoid ugly rocks in the middle of the run. At the top of the rapid is a small boulder in the center of the river. Once you've passed the rock, pull right and then manuever around to hit the channel on the right.

The Gates of Lodore is an amazing western run, with scenery that rivals the Grand Canyon and rapids that are a little more eastern in nature (much like the Nolichucky). We ran this section at the end of June and the found the water levels to be around 845cfs. At this level, many of the rapids were technical (Middle Disaster Falls) though not horribly difficult in our oar rigs. Duckies and kayaks found it to be a very fun level. The pictures show several of the rapids (although they're not in the right order). The most notable rapid was Hell's Half Mile. We used the Rivermaps Dinosaur National Monument guide. It's much more detailed than the Belknap's guide, giving you more topo information. Make sure you read the permit info carefully as the ranger at the put-in was a stickler. He even asked to see the groover, the first aid kit, the repair kit, the firepan (collect your firewood before heading downstream), and all the extra PFDs and paddles. River Runner's Transport in Vernal, UT, ran our shuttle and did a great job. They even hooked us up with a few pieces of river beta before setting out downstream (info on rapids and hikes). This is an amazing stretch of river; unfortunately only about 300 permits are given each year.
