The Colorado River cuts an impressive course through Cataract Canyon creating an exciting big water experience. Although faster runs can be made, four to five day trips departing from Potash Boat Ramp downstream of Moab make for a 100 river mile trip that provides a balance between quiet floating, impressive geology, prehistory in canyon country, cool hikes, beach camping, and fast-paced rapids. The trip is an all-around river adventure with spectacular scenery. While this is a great trip for intermediate boaters during the summer or fall, the flows of spring snowmelt provide a high water challenge that should only be attempted by expert big water boaters. The Colorado River through Cataract Canyon at 50,000 cfs is extremely big, pushy, and powerful. The rapids come in quick succession with no recovery time making long swims in cold water a very real possibility.
Cataract Canyon begins just below the confluence of the Green and Colorado Rivers in Canyonlands National Park but this location is not accessible by vehicle. Paddlers have a few options that include boating approximately 50 miles down Meander Canyon of the Colorado (from the Potash Boat Ramp near Moab) or Stillwater Canyon of the Green (from Mineral Bottom Access). Kayakers may be able to arrange a jet boat shuttle from Potash Boat Ramp to Spanish Bottom to avoid the flatwater paddle in. Another option, popular with packrafters, is to hike in from the east along one of the trails in the National Park that provides access to Spanish Bottom.
Beginning at the confluence of the Green and Colorado Rivers, the river is flat for the first three miles before the rapids start and remain more or less constant until the reservoir drowns the river. A short flatwater section (1.5 miles) between rapid 12 and rapid 13 is the prelude to the Mile Long Rapids; this section culminates in the Big Drop Rapids. Scouting Big Drops 2 and 3 at all water levels is recommended. At low water these drops can be scouted
...This is the start of Cataract Canyon. Life jackets are required from here through the last active rapid on Powell Reservoir.
Hole in the center at low water with an easy line around the right. The beach below this rapid on river right is a nice camp and has a trail upstream of camp that provides access to the Dollhouse.
Rocks to the left at low water; go center right.
At low water this rapid forms a large hole towards the bottom of the rapid on the left that is hard to see from the top. The right side is a series of pour overs that can be run, or start in the center and move right below the pour overs.
Some big rocks are exposed on the right at low water and a good line is down the left.
A longer but straightforward rapid that comes right after Rapid 6. The river bends around to the left and then back to the right. Just follow the main current.
This rapid offers a couple options and has a few rocks to avoid at low water and a wall at the bottom right. Down the right side is good.
Rapid 10 comes in quick succession after the previous rapid and features a big wave at low water that is fun surfing for the kayakers and a good hit for rafts. There are some good camps in this area. The Upper X/Y Canyon R Camp is between Rapid 9 and 10, Middle X/Y Canyon R is at the top of Rapid 10, and Lower X/Y Canyon R is adjacent to this surf wave in Rapid 10. A relatively calm stretch of river follows Rapid 10 before the actions starts to pick up again about 3 miles downstream.
Rapid 11 is a relatively inconsiquential riffle.
This is a relatively easy rapid where the channel is constrained by debris from the side canyon river left.
This rapid is formed by outwash from Range Canyon that comes in from river right. It's a relatively straightforward rapid that begins the fun sequence of approximately 3 miles of whitewater that ends with the Big Drop Rapids.
Beware of the hole in the center. This rapid is also formed by outwash from Range Canyon.
Several midstream boulders and a line down center right.
This rapid forms a very large hole in the center at high water (35,000 cfs+). At lower water it is a large mid-river rock and a wave hole on the left. There are runs on the right and left depending on water level.
The river splits around an island. Take the river right channel; the run is left of center with holes and pour overs on the left and right.
Big Drop 1 represents the start of the most signficiant stretch of whitewater in Cataract Canyon. At lower flows you can read and run down this rapid but at higher flows most pull out above this rapid on the left and scout the whole sequence of whitewater through Big Drop 3.
Big Drop 2 requires either hard left to right below the marker hole/rock or right to left pull between the marker hole/rock and Little Niagra. Either one reqires a run of the ledge wave. Hit this square. The left to right move is prefered at lower levels (below 40,000 cfs). At high water there are sneak runs but they are not without consequences. The low water scout is on river left above the rapid. At high water it is usually scouted from the left above Big Drop 1 and running all 3 Big Drops at once.
The biggest rapid on the river. At high water the run is down the right as Satan's Gut forms on the right. At low water a good raft line opens up on the left but there are consequences on either side of the line so it's a good idea to scout. Kayaks have a few more options with lines on the left or right.
This rapid has a midstream island. Take the right channel and enjoy fun waves. It takes its name from Don Harris who found two nickels in the sand.
Long rapid at the mouth of Imperial Canyon with big waves at the bottom. The rapid came and went as reservoir levels fluctuated throughout the 1980's and 1990's. It is the first place where significant reservoir deposits are observed, known as the Dominy Formation, and the transition to the Returned Rapids area.
A short distinct break after the rapid above marks Short Rapid. Enjoy the fun waves down the middle in the narrowest part of Cataract Canyon.
Easy read and run. This rapid was carved out of the sediment between 2007-2012.
A prominent tower on river left that resembles a can opener gives this rapid its name.
This riffle is close to the first benchmark that the USGS established to measure the rate of change in the area as part of the Returning Rapids Project.
This rapid first began to appear as a riffle in 2018. As of fall 2021 this rapid marked the carving zone of the Dominy Formation sediments and the last rapid in Cataract Canyon. In 2024 this rapid has become much more signifigant, and should be scouted on the left.
Not yet showing. Dark Canyon is a major canyon on the left. When the reservoir is low, the river elevation here is about 3540 feet. Before the reservoir was filled, boaters encountered a major rapid here but as of 2021 a riffle was not even visible. The rapid is currently buried beneath the sediment of the Dominy Formation, formed when the sediment-laden water of the Colorado River hit the slackwater of the reservoir. As the reservoir drops, the historic channel may be revealed although the course the river chooses near the Dirty Devil confluence will have implications for the rate that can be expected to occur.
This take out is on the north side of the reservoir, just downstream of the mouth of the Dirty Devil River on river right. It can be difficult to find a good place to beach because of large areas of mud flats, quicksand, and steep banks. It is also easy to get cars stuck in the soft sand and there have been close calls with vehicles nearly ending up in the river. It is not possible to back a trailer down to river level when the reservoir is low. Outfitters use a winch and series of rollers to pull boats up the steep 'ramp.' This is generally the only take-out available as Hite Marina is usually inaccessible. Contact the National Park Service about current ramp conditions as they can change quickly.
Except on very high water years that fill the reservoir this ramp on river left downstream of the Dirty Devil confluence is not accessible. The concrete ramp is generally high and dry, with several hundred feet of mud flat between it and the channel.

Jen, Sam, Sasha and I did a loop starting at the back of fable valley, hiking to the confluence and walking back up bowdie. I wouldn't really recommend hiking up bowdie.

Large Pour over middle right. The current pushes towards it.

10/29-11/1, 2024. @ 6,000 cfs
Three packrafters hiked in from The Needles District, using a cross-country route that follows remnants of an old hand-built mining road. The access road to get to the cross-country route is high clearance itself. 4WD is required or you are liable to get a ticket from the NPS, AWD doesn't cut it (I got a written warning for using a Subaru). The route starts near the Needles Welcome Center, and reaches the Colorado about 5 miles upstream of the confluence with the Green River, near 'The Loops'.
Day 0: Set shuttle and camped at Hamburger Rock near the Needles District
Day 1: We hiked and paddled to Spanish Bottom.
Day 2: Side hike up to Doll's House, then paddled to XY camps.
Day 3: Paddled the whitewater, and camped at Clearwater Canyon
Day 4: Paddled 23 miles to the North Wash take out, kind rafters with a motor let us hang on and towed us for much of this last day. We ran shuttle and camped near Hamburger Rock again.
If I did it again, I'd add one more day to the trip. It can be done much faster, but I think one more day would have allowed for the ability to be on 'river-time'. While our pace was still nice and plenty enjoyable, it did require the use of a clock and the need to make miles was felt on a couple of the days. I thought flows were good for packrafting and kayakers looking for a class III/IV trip. There were a handful of fun rapids below Big Drop Three, and we had current all the way to the take out due to the lowering of Lake Powell, though the current slowed significantly after we passed the warm springs not far upstream of the Hite Bridge.
Gypsum Rapid felt IV-, and there was a small wavetrain between the two warm spring above the Hite Bridge that hadn't been there the week before. This rapid surprised the group motoring out, who had two rafts lashed together and ran the rapid that way.
Have a plan for water, the silt in the river means it's best to let it settle overnight before filtering if you don't bring enough for the whole trip (not such a problem for rafters).
Here is a video from our trip to get a feel for the rapids at 6,000 cfs: https://www.youtube.com/watch?v=cfCOT18OSqc
