The Green River is a very long stream forming in the Wind River Range of the Rocky Mountains in Bridger Teton National Forest of Sublette County, Wyoming, then winding its way south into Utah, turning east into Colorado and finally back south down into Utah where it terminates at the confluence of the Colorado River in Canyonlands National Park in San Juan County. The featured section is the 19 miles of Lodore Canyon, the upper end of this 44 mile run from the Lodore Ranger Station in extreme northwestern Colorado to Split Mountain Campground in Utah, though trips can continue another 8 miles to US Highway 40 near Jensen. This reach of the Green River encompasses Lodore, Whirlpool, and Split Mountain Canyons, all of which are quite scenic.
The Green River flows through Dinosaur National Monument where Lodore Canyon is located. This predominantly Class III whitewater run is in the high desert, with towering sandstone mountains on either side. Permits from the National Park Service are required for trips in this area, and are not easily come by. However, a trip here will be well worth any effort required, and the permit system limits overcrowding on a very popular section of the Green River. Contact Dinosaur National Monument River Office (970-374-2468) for permit information. During the heart of the season campsites along the river will be assigned by the NPS according to paddlers' itineraries, so be sure to have a good idea when and where you want to paddle when you contact the NPS about getting a permit. Camping is allowed ONLY in designated sites at all times. Most river runners camp at the Gates of Lodore Campground the night before starting their trips.
Ancient petroglyphs can be viewed on the lower reaches of this section. Fishing is excellent on the Green River, and Jones Hole Creek in Utah offers a great location for trout (be sure to have a fishing license and a trout stamp). The water is cold and clean, a necessity for trout populations, so paddlers need to wear appropriate clothing to protect against hypothermia. Numerous birds of prey and wild animals, including Bighorn sheep, are often seen on this section. What will NOT be seen are signs of civilization other than paddlers, and some of them are not all that civilized!

The Green River through Lodore canyon flows murky and cold. Its water quality is good, but not drinkable without purification. It is recommended that you bring your own drinking water since river water may be too silty for adequate filtration and purification. Snowmelt and late spring rainfall are the primary sources of water in the river. Dam releases from Flaming Gorge Reservoir in Utah may provide additional flow from time to time.
The prime season for Lodore Canyon of the Green River is April through October, and sometimes after a fall release of water from Flaming Gorge Reservoir in Utah. Typically, river trips can be made at any time of the year, weather conditions allowing.
Any trip through Dinosaur National Monument requires an elusive and hard-to-obtain permit issued by the DNM River Office. High use seasons run from the second Monday in May through the second Friday in September on the Green River, and through July 14 on the Yampa River. Low use and/or low-water permit seasons are all other times. Lottery applications must be submitted between November 1 and Febraury 1. For detailed information please visit the Dinosaur National Mounment web site.
There are numerous Class III rapids through Lodore Canyon that require vigilance in negotiating them safely. Though none pose threats of imminent danger to intermediate or higher level whitewater paddlers, or even novice paddlers in guided rafts, attention to the task at hand is necessary. The first significant rapid is Upper Disaster Falls, followed quickly by Lower Disaster Falls, a couple of great Class III drops that are fun and challenging, located between Jack Draw (on river left) and Zenobia Creek (on river left) starting about 5 miles below the put-in. Next comes Harp Falls, located just below Zenobia Creek and Pot Creek (on river left) about 7 miles below the put-in. Triplet Falls at about 11.0 miles below the put-in requires a hard left turn away from the right bank. Avoid the cut-away rocky alcove at all costs! Hell's Half Mile is located about a mile or less below Triplet Falls, and is the last significant rapid on this section of the Green River, though numerous other Class II to III rapids will be found between Hell's half Mile and Split Mountain Campground. Hell's Half Mile can be scouted from river left for a view of a boulder garden with a fairly large-sized hole (at high water) or a large rock (at low flow).
It should be noted that several of these larger rapids can approach Class IV characteristics in high water conditions, and have have Class IV consequences at any level due to the remote location and its inaccessibility except by boat along most of the run.

NOTE: All campsites designated as NPS campsites are assigned by the rangers of the National Park Service when permits are issued for trips during the peak of the season. Always check with park rangers about campsites before beginning a trip, and stick to your paddling schedule so that you arrive at your designated campsite before dark. The NPS offers primitive campsites, so be sure to bring along everything you will need, and protect it in drybags. Also, boaters on multi-day trips CANNOT camp at either Echo Park or Rainbow Park.
There are at least ten commercial outfitters who are NPS-aproved vendors offering rentals, shuttles, guided trips and/or river information for Green River trips in Colorado and Utah.
If there is a single drawback to paddling Lodore Canyon, then that would have to be the popularity of the place. During the peak of the season the Green River attracts a lot of traffic, and below Echo Park that is enhanced by paddlers joining the Green River from the Yampa River. However, assuming you can get a permit, that is not a decent reason to avoid paddling Lodore Canyon. The majestic sandstone mountains, deep canyon walls, wildlife, and picturesque scenery all around, as well as great Class II to III whitewater rapids, make Lodore Canyon a favorite trip for many paddlers in canoes, kayaks and rafts. Be sure to take along at least one gallon of water per person per day for drinking and food preparation, as well as additional water for hygiene purposes. Pack a camera, because you are going to need it here! Unfortunately, the normal season is usually limited to April through October, but controlled releases from Flaming Gorge Reservoir (Utah) will allow trips in the normal off-season. Check with US Army Corps of Engineers at the lake, or contact the Lodore River Office for release information.
