River Description

The Yampa is a classic multi-day whitewater river. Most boaters spend 3 to 5 days floating the Yampa and Green Rivers that comprise this run. For most in-season runs a permit must be acquired from the Dinosaur National Monument Ranger Station. These permits are highly competitive and the possibility of winning a permit varies year to year. The permit generally specifies the camping beaches for each float trip.

This page describes the Yampa to the confluence of the Green at Echo Park.  Boaters almost alway continue another 26 miles down the Green Echo Park to Split Mountain section. The total distance of the two sections is about 72 miles.

As a high desert run the weather pattern of the Yampa River can range from freezing to over 100 degrees in less than a day during the early float season. Later runs in July or August are generally hotter and more predictable but can suffer from low water and mosquitoes.

Almost every big rapid on the Yampa can be scouted on river right. The Yampa at Deerlodge starts as a wide meandering river in an open desert. Within a mile or so it enters a box canyon and some easy but continuous rapids begin. There are several notable rapids on the Yampa and the gradient is fairly constant for most of the first day. On the second or third day of paddling the Yampa becomes tranquil as it approaches its largest rapid, Warm Springs.
Scout Warm Springs from river right. A huge flood that temporarily dammed the river formed this rapid. The rapid itself would not be much more than an easy class IV drop were it not on a multi day river excursion. Flipping a raft in Warm Springs almost always results in an unpleasant night with wet or lost gear.

Below Warm Springs the river continues to present complex rapids and wave trains, but never approaches the difficulty of Warm Springs until after the confluence with the Green in Split Mountain Canyon.

Any whitewater boat (C-1, OC-1, OC-2, Raft, K-1, K-2, etc can float the Yampa.)

Rapid Descriptions

Deerlodge Park

Class - Mile - 0
The best river access for the put-in.

Anderson Hole

Class - II+ Mile - 1.2
The first notable rapid is Anderson Hole. This drop is easy but makes a river wide horizon line after the box canyon opens up. Some play waves exist here.

Yampa Canyon

Class - Mile - 1.5
After a 1.5 mile float you will enter the Yampa box canyon.

Tepee Rapid

Class - II+ Mile - 10
A wave-train with large holes at high water.

Big Joe

Class - II+ Mile - 22.5
Rapid Thumbnail Missing
The Yampa is squeezed down at this point and the rocky debris in the river creates a wave and hole filled rapid.

Tiger Wall

Class - Mile - 37
Rapid Thumbnail Missing
A tiger striped wall on river left. Boatsmen kiss the wall for good luck.

Warm Springs

Class - IV Mile - 42

The largest rapid on the Yampa. A 1965 Debris/Flash flood event formed this rapid rated among the 10 biggest drops in the country. Scout from the right.




Class - Mile - 42
Numerous hot and cold springs flow into the Yampa and Green River. However, the springs at Warm Springs are not warm at all.

Warm Springs/Maytag

Class - IV Mile - 42.01
The last hole in Warm Springs is named Maytag and can flip rafts or work over boaters.

Echo Park

Class - Mile - 46
Rapid Thumbnail Missing
The confluence with the Green river

Just ran this at 1400 with my 17 foot cat and other 18 foot boats and barely made it through big joe. The hole at warm spring at this level was nothing and we all took turn running right through it with our duckies. Great beaches. Great camping. Its a shame they don't give out more permits since there are so many camping spots. It took me 10 years to get this permit

Cross Mountain Gorge is my favorite kayak run in Colorado. But I only know it at low flows around 1500 cfs. Filled with eddies and the rapids have great twists, sneaks, and surprises. Everyone on the river is always pumped up! IV+...significantly harder than the Numbers on the Arkansas but not nearly as hard as Gore Canyon. This makes a great first IV+ run.

Voluntary River Closure Proposed On the Slate River (CO)

Kestrel Kunz

Crested Butte CO - Alleged disruption to a Heron Rookery and concerned private landowners have led to a "Voluntary Closure" of the Slate River from the Gunsight Bridge to the Town of Crested Butte between March 15 and June 21 for the 2019 season. The Slate River between Oh Be Joyful Campground and Skyland Bridge, a 10.5 mile stretch, provides an incredibly scenic and unique flatwater paddling experience in the Gunnison Valley. The Voluntary clsoure is a product of the Slate River Floating Management Plan, created by a Working Group convened by the Town of Crested Butte and the Crested Butte Land Trust. The Working Group was created in direct response to pressure from the local community including conservationists and private landowners adjacent to the river, who are concerned that a recent increase in boating activity is disturbing a Heron Rookery that straddles the Slate River.

AW Comments on Colorado Nat'l Forest Wilderness Process

Kestrel Kunz

Today, September 5, marked the close of the public review process for the DRAFT Wilderness Evaluation Report. The Evaluation Phase is the second step of 4 different steps required in the assessment of lands that may be suitable for inclusion in the National Wilderness Preservation System (NWPS). American Whitewater thoroughly reviewed the DRAFT Wilderness Evaluation Report and submitted our comments to the Forest Service on September 4, 2018. Overall, we found that key paddling reaches throughout the GMUG area were greatly under-represented in the Polygon narratives and thus weren't acknowledged as contributing factors to the Polygon's respective Wilderness Ratings. We let the Forest Service know this, highlighting specific paddling reaches that should be added to each Polygon and which Polygons we believe should have a higher Wilderness Rating based on the high-quality recreation opportunities that each area has to offer. 

Please stay tuned as we continue to report on the GMUG Land Management Revision Process and in the meantime you can learn more about the GMUG here. (Photo of Josh King by Nick Spitzer)

A Successful River Cleanup on the St. Vrain (Lyons, CO)

Kestrel Kunz

On Sunday, nearly 50 people gathered on the banks of the St. Vrain River to pick up trash from the water and the shoreline. We started the day off with Hotbox Roasters coffee and donuts, and a few words about River Stewardship – the common cause that brought us all together. We found bedframes, rusty nails, lawn chairs, car doors, plastic water bottles, candy wrappers, fast food containers, and it doesn’t stop there. Our findings are likely a combination of leftover debris from the floods, illegal waste dumping along the river, and built up trash from years of careless passers-by. Thank you to all those that came out for the river cleanup! American Whitewater depends on our affiliate clubs, members, and dedicated volunteers in order to tackle our many River Stewardship projects.

Take Action on Colorado's Right to Float Bill!

Nathan Fey

This spring, the Colorado Legislature is considering a bill, which helps protect the rights of commercial boaters to float on commercial sections of river, and increases the safety of boaters by decriminalizing incidental contact with private land to portage obstacles.

We urge you to contact members of Colorado’s Senate Judiciary Committee and ask them to support HB-1188, and to amend the bill to include all members of the paddling public.
