Welcome to the river permit lottery application site for Dinosaur National Monument-home to the Green and Yampa Rivers, two of the west's premier whitewater rivers.
Green River: Gates of Lodore
The Green River flows south out of Browns Park into Dinosaur National Monument and cuts through the Uinta Mountains, the largest east-west extending mountain range in the lower 48 states. Within the monument and along this stretch of the Green River lies the imposing Canyon of Lodore, which received its name from John Wesley Powell's expedition in 1869. Three of the rapids so impressed Powell that he named them Disaster Falls, Triplet Falls and Hell's Half Mile.
The 19-mile run down the Green River from the Gates of Lodore to Echo Park is different today than in Powell's time, largely because of the dam at Flaming Gorge which regulates the water flow. This allows for a longer rafting season, but one that is not greatly affected by spring run-off. There are many named and unnamed rapids, well-spaced as in most pool-drop rivers and plenty of beautiful river side campsites and hikes, dominated by the almost 2,000 feet high red cliffs.
The Yampa River begins at Deerlodge Park and rushes downstream 44-miles to join the Green River at Echo Park. Boaters continue downstream on the Green River to the take-out at the Split Mountain boat ramp. The Yampa is the largest free-flowing tributary within the Colorado River system. As such, it has a shorter season marked by fluctuations in water level resulting from snow received in the winter. It is characterized by famous rapids such as Teepee, Big Joe and Warm Springs.
Below the Confluence of the Yampa River and the Green River
All trips continue downstream on the Green River from Echo Park through the 17-mile Whirlpool Canyon. It was named by Powell because of the squirrelly and unpredictable water the explorers experienced here. The last section of the Green River in Dinosaur National Monument is the nine mile Split Mountain Canyon. This canyon begins at the Rainbow Park boat ramp and flows swiftly downstream, punctuated by four named rapids and assorted riffles before reaching the take-out at the Split Mountain boat ramp.
Camping facilities exist at the Lodore and Deerlodge launch sites. Each has campsites, water available seasonally, an information station, staffed ranger station, and vault toilets. These remote sites do not provide trash receptacles because of bear storage issues. The launch locations are primitive to help the visitor transition to the wilderness environment of the canyon. Due to the remoteness of the area and long drive times, many groups camp at their launch site the night before their river launch.
The Split Mountain take-out offers reservable group campsites (flush toilets seasonally, no showers), vault toilets and a seasonally operational groover dump site. Nearby is the world famous Dinosaur Quarry Exhibit Hall where you can see 149 million year old dinosaur bones encased in the rock.
Dinosaur National Monument - 2020 Season
As we work through an unpredictable and rapidly changing situation, health and safety of visitors and staff is our priority. We are committed to continuing support of our communities and fulfilling our mission as we work together to minimize the impacts and spread of COVID-19.
As of June 7th, 2020, Dinosaur National Monument is issuing multi-day and daily permits to float the Green and Yampa Rivers. We have modified operations in launch and take out procedures to ensure a safe distance is established between groups. Please follow the directions of monument staff as we work through these new procedures.
Check-in & Rigging: The permit holder must be present for a trip to begin rigging. Permit holders should check-in with monument staff upon arrival at the boat ramps. Staff will facilitate rigging locations to ensure a safe distance between groups.
Take Out: Rafting groups will be contacted by monument staff as they approach Split Mountain Boat Ramp. Due to high congestion at the boat ramp, groups may need to wait upstream prior to de-rigging. Several lanes have been closed to ensure a safe distance between groups.
Water is available at Lodore, Deerlodge, Echo Park and Split Mountain. The Split Mountain dump station is also open.
Monument managers are continually monitoring and assessing the situation and will adapt as needed to changing conditions.
Follow these best practices to minimize risk of transmission of Covid-19:
The water at Gates of Lodore, Deerlodge Park, Echo Park, and Split Mountain dump station and campground will be shut off on October 19, 2020 for the season. Please bring all the water you will need for your trip with you to the put-ins.
Boating within Dinosaur National Monument is by permit only. This permit allows the permit holder to float the Green or Yampa rivers. Permits are non-transferable and are for one launch only.
