The Upper Klamath (often called "the UK") flows from Upper Klamath Lake in Southern Oregon to Copco Reservoir in Northern California . The Hell's Corner section starts at JC Boyle Powerhouse and ends at Copco Reservoir. The powerhouse is located about 30 miles from Klamath Falls and 50 miles from Ashland.
The Upper Klamath flows through a secluded canyon with gorgeous scenery, abundant wildlife, and a lot of whitewater. The first 5 miles are relatively easy with class II and III rapids for warm up. The 7 miles that follow are known as Hell's Corner Gorge! The rapids are more frequent and they are long. While many people refer to the Upper Klamath as continuous in nature, it really is a pool drop river. The difficulty increases due to the length of the rapids, the numerous 90 degree blind corners and the brown water which camoflages the rocks.
The rocks create the majority of the hazards, mainly pins and nasty swims. At high water these hazard lessen, however the Upper Klamath doesn't wash out it just gets bigger, and develops a mean push over 3000 cfs.
On the fun side the Klamath offers some play on the fly, 6-8 foot haystack waves, and 3-4 foot pile on friendly holes!
The Upper Klamath is a remote river and has little access.
Spring Island Launch is the main put-in about 1/4 mile below the powerhouse. There is a trip registration box, pit toilets, gauge, and a practice eddy. Overnight camping at the Spring Island Launch is prohibited. Campers should stay at Topsy Campground located along Boyle Reservoir just upstream. For those that wish a back woods camping experience a rough 3 mile drive past Spring Island put-in down the jeep road along the river leads to the BLM camps. Outhouse toilets and fire pits are available.
Frain Ranch is an alternative put-in that shortens the trip by about 5 miles. Frain Ranch is a great place to camp however there are no facilities. There used to be a composting toilet that BLM had to close due to vandalism. Most campsites have approved fire rings. Know the fire regulations before you build a fire. There are 2 main places where boaters put in at Frain. Using either put-in, you are about 10 minutes above Caldera Rapid.
Stateline Access is the first takeout on river-left after the gorge and is a popular place to take-out for those that put in at Frain Ranch. There is camping and (during the summer) a port-o-potty. Access #6 is a short distance downstream on river-left and is the take-out typically used by commercial outfitters because it comes at the end of the big whitewater.
Access #1 is located at the beginning of Copco Reservoir on river-left and is the primary take-out for most boaters. There is no camping at Access #1, but there is a port-o-potty. The take-out is easy to recognize because you will be entering the reservoir and will see the first couple homes that are part of the Copco community in the distance.
There are few shuttle services for the Upper Klamath. For trips starting at Spring Island and ending at Stateline or #1 a shuttle driver is recommended. Call one of the raft companies a couple days in advance if you are looking for a shuttle service and they can typically recommend a raft guide or shuttle driver they use who is not working that day. From Spring Island to either of the take-outs the shuttle is approximately 100 miles. Please refer to the shuttle map to plan your trip.
March 22 2011 Nick Sinderson provided:If you have a high-clearance 4-wheel-drive vehicle and a bike, you can simplify your shuttle by using the road on the south bank (which has three different names: Copco Lake Road, Ager Beswick Road, Topsy Grade Road). If you GoogleMap 'Copco Lake Road' you'll see where to go. Some people find using this access a bit unnerving as you'll be putting in right above Caldera with no warm-up, but it relieves the need for a shuttle driver and cuts shuttle time by hours.
Thanks, Nick, for that info.
The Klamath Canyon is rich with 'Wild West' history. The main stage coach route from Yreka to Klamath Falls traveled up the south side of the canyon which is now the Topsy Grade. Along the road are small history markers that tell the tales of the ranchers and stage coach robberies.
The primary industry used to be logging the large ponderosa pine. After cutting the trees loggers would slide them down a chute to the river where they could be floated down stream to the mill. The remains of the Pokegama log chute can still be seen by those with a keen eye.
By visiting the Frain Ranch, all sorts of historic relics can be seen which tell tales of the hardships and rewards Martin Frain must have gone through while he was homesteading this area.
The water rights issues of the Upper Klamath are complicated and seemingly endless. Water is needed both upstream and downstream in a basin that is regularly in drought.
The Upper Klamath (UK) starts off with a small taste of what is to come. Fifty yards out of the practice eddy, boaters float into Saddle Horn. The brown water hides the rocks and the current sweeps boaters into the second rapid (Saddlehorn) as if they were one long rapid. Welcome to the UK!
Caldera is Spanish for the boiling caldron. Boaters know it as The Gateway to Hell (Hells Corner Gorge that is). From here to Stateline Falls the whitewater action is nearly constant. Caldera changes quite a bit between 1 and 2 generator flows. To see where the current is going and which rocks need to be avoided a scout from river left is recommended.
The large hole 20 yards into this rapid gets very large at 2 generators. The rock just below this hole is known as the 'Mushroom Rock' running to the left or right of Mushroom are both standard routes.
Caldera is a long class IV rapid and scouting its entire length is difficult and not very practical. Scout just the upper portion since the difficult moves are all before "Mushroom Rock".
The last wave in the wave train is really a sharp submerged rock.
At 2 generators the hole in this rapid becomes huge -- a very large flushing hole capable of flipping large rafts.
On most summer days Del (with WOA) is taking photos from river left at the large fun hole 2/3 of the way through. Be sure to smile and travel into Copco to see the pics.
A 150 yard 90-degree right-hand turn with large holes, large waves, and large rocks river left. Satans Gate starts the three rapids that make up Hells Corner. The current sweeps pretty immediately into Hells Corner Rapid, so swims should be avoided if at all possible!
Hells Corner is a 300 yard long class 4 rapid. I have broken this rapid into two sections even though they are continuous. Scouting Hells Corner is difficult and takes alot of time.
Hells Corner starts on a blind left hand corner. Enter with the main current. Once the holes and waves subside, work through the sleepers back to river center and prepare for two large waves.
After you have worked back to river center you will find two 6' haystack waves that are a lot of fun. Once past these, you want to get hard right (at 1 generator) or left (at 2 generators) in order to prepare for the final 90-degree right-hand corner. This last part contains (among many others) the wrap rock known as the Ego Bruiser'. At one generator you can catch the safety eddy on the right below Hells Corner and prepare for the Dragon. At 2 generators these two class IV rapids run in succession.
A large fun hole lurks at the top. The current will push you into the Dragons Teeth: two submerged rocks in the middle and at the end of the rapid. The best waves are to the left of these obstacles.
you can simplify your shuttle, if you have a high clearance 4 wheel drive vehicle and a bike by using the south bank rd (which has three different names; Copco Lake Rd., Ager Beswick Rd.. Topsy Grade Rd.) By google mapping Copco Lake Rd. you'll see where to go. Some people (including me) find using this access a bit unnerving as you'll be putting in right above Caldera with no warm-up. But it relieves the need for a shuttle driver and cuts shuttle time by hours.

PacifiCorp's proposed Recreation Plan assuming relicensing of Klamath Hydroelectric Project.
A whitewater guidebook to the Pacific Coast of the United States from the Rogue River to the Salinas Valley in California.
Release Information Pacific Power and Light Company operates Boyle Powerhouse for power generation and through this operation navigable flows occur all summer.
To get the daily release information directly from Pacifcorp: View the Summer Operational Schedule visit the unit start time web page http://www.pacificorp.com/hydro_hiws/JCBoyleEstFlow.html. Call the public service recording at: 1-800-547-1501
Most guides on the UK refer to the flow in terms of the generators that are running for the day. 1 generator refers to flows from 1200-1800 cfs where 2 generators refers to flows of 2200-3000 cfs. On the lower side of the spring island eddy there is a gauge marked off in terms of generators. Launch when the water level is at the 1 generator mark. It is possible to float the creek to Caldera at base flow however if for some reason the release does not happen you will not be able to continue to the take out.
It takes the release about 1 hour to reach the top of Caldera and consequently the same during ramp down. Keep this in mind when you take time to scout, lunch, play, or resolve incidents. Always keep an eye on the water marks on the rocks. This can give you clues to any operational changes at the power house.
There is always the possibility of a mechanical failure causing unplanned outages. Any unplanned outages at J.C. Boyle could impact the rafting schedule. Check the water release schedule daily, to see if unplanned outages have any effect on rafting.
The intent in providing the above information is to provide raftable flows, as listed. However, if difficulties arise in the power supply situation, PacifiCorp reserves the right to operate the project later in the day or as necessary. PacifiCorp recommends all river users check the water release schedule daily, to verify flows and release times. If you have questions or comments about the information provided herein, contact the Klamath Project Production Manager, (530) 459-2003.

This week, Oregon House Bill 2835 re-passed the Oregon House on a 52-7 vote. Having earlier cleared the Senate, the bill now awaits a signature from the Governor to be signed into law. For decades, opportunities to protect and improve the ability of the public to access and legally use waterways for recreation have seen minimal progress, while efforts to severely limit access have been a consistent threat. Oregon House Bill 2835 is a pivotal piece of legislation in Oregon, and the first proactive waterway access bill in recent history to have made it through the state legislature.
Take action today using our easy online form to protect National Monuments designated under the Antiquities Act! A public comment period began on May 12th and ends July 10th for an April 26th Executive Order which directed Interior Secretary Zinke to conduct a review of all Presidential designations over the past 21 years. A number of Monuments being reviewed are of significant interest to paddlers and provide protections for cherished whitewater stretches, including Bears Ears (Lower San Juan River, UT), Grand Canyon-Parashant (Colorado River, Grand Canyon, AZ), Giant Sequoia National Monument (Tule River, CA), Katahdin Woods and Waters National Monument (East Branch of the Penobscot River, ME), Rio Grande del Norte National Monument (Rio Grande, Taos Boxes, NM) and many more.
On Thursday, April 4th, the Department of Interior recommended removing four dams on the Klamath River, listing the action as the Preferred Alternative for a long-term solution to address native fishery and water resource issues in the Klamath Basin. The recommendation was set forth in the Department's Final Environmental Impact Statement (EIS), which provides a comprehensive review of whether partially or fulling removing four dams owned and operated by PacifCorp will help to restore salmon runs to the Klamath River.
A public comment period is now open for the restoration of the Klamath River through November 21st. Secretary of the Interior Ken Salazar announced in late September that the federal government has completed numerous peer-reviewed scientific and technical studies providing new and detailed information about the environmental and economic impacts of removing four Klamath River hydroelectric dams.
