Global Whitewater Boating - Shangri La River Expeditions
Whitewater Boating Types of River Craft Maneuvering, Hazards & Safety Famous Rivers of the World Famous Rivers of the Western US Environmental Issues Reed canoe -5000 BC The boatman is now a mummy :) Open canoe in Lava Falls on the Colorado River in the Grand Canyon. Eskimo kayak This guy was giving free kayak rolling lessons :) Modern playboat Racing kayaks are 4 meters long, fast but hard to surf and do other tricks on waves. In the 1970s, the first plastic kayaks became available, and it was possible to cut them down for playing. By the 1990s, short “rodeo” boats were outselling racing boats and many river towns began to build whitewater parks and hold annual rodeo competitions. Stand Up Paddleboard Called an SUP for short, these are actually inflated to a very high pressure, so they can be deflated and easily carried in a car trunk or on a raft. It takes very good balance to paddle one, but if you fall off it's very easy to right it and climb back on. Parents are starting to take their children, who learn quickly. Gowa or Coracle This type of boat has been popular in Tibet for centuries, where they're made of yak skins and can be used to cross the low gradient rivers typical of the Tibetan Plateau. This pic was taken on the Kyi Chu about 100 miles upstream from Lhasa, the capital city of Tibet. “Powelling” This stamp was sold in 1969 to commemorate John Wesley Powell's historic descent of the Green and Colorado rivers from Wyoming, through Utah and the Grand Canyon, ending at the confluence with the Virgin River on the Arizona – Nevada border. Big water rafters and dory boaters occasionally still use Powell's technique of rowing downstream to develop momentum, either to plow through waves or to move across the current to less challenging whitewater. Cataract boats Cataract boats were first built in the 1950's by Utah river guides to run Cataract Canyon of the Colorado in what's now Canyonlands National Park. In this picture, they're being used to run the Yampa and Green in Dinosaur National Monument, and people still take them through the Grand Canyon. Mexican Hat Expeditions, which pioneered their use on the San Juan River, eventually changed its name to Canyoneers and began running large motor rafts in the Grand Canyon. Modern whitwater dory Dories can be made of wood, aluminum or fiberglass. They're decked over to avoid swamping, and some are even self bailing. They float like corks and the ride is really great. However, they flip more often than rafts and don't bounce, so it takes more skill to row one. Grand Canyon Dories still operates dory trips in the Grand Canyon (now a division of OARS). Inflated goatskin raft Subsistence farmers still use these rafts to cross flatwater sections of large rivers such as the Yangtze, where this picture of tourists was taken. Modern inflatable raft The transition to modern rafts made of nearly indestructible airtight chambers was made possible by military surplus inflatable assault boats, life rafts and bridge pontoons. These were used for about twenty years, until the whitewater rafting industry expanded enough to justify the manufacture of a wide variety of self-bailing inflatable rafts. Although flips occur, they are not common and with rare exceptions, the just add to the river adventure. Creature Craft This boat is self righting and used for highly technical high gradient rivers. However, it only carries two people and doesn't carry much gear, so it's typically not used for multi-day trips unless the rapids are suitable for support rafts. Wooden sweep boat These boats were developed for use on big flatwater rivers such as the Columbia and lower Snake, but a talented guide could also take them down mountain rivers at highwater, such as the Main Salmon, and one man, Buzz Holstrom, took one down the Green and Colorado, including Cataract and Grand Canyons in the late 1930s. They're too big and heavy to portage, so Buzz was the first person to run every rapid in the Grand Canyon. Inflated sweep raft The availability of modern inflatable self bailers made it possible to use sweep rafts for gear boats, such as this one on the Middle Fork of the Salmon in Idaho. The guide goes to ahead of the rafts or dories to set up camp, giving passengers more time to fish, swim in hotsprings or go for hikes. Georgie White motor raft Georgie White pioneered the use of military surplus bridge pontoons to take large groups of people, mostly from LA, on discount trips through the Grand Canyon. She'd strap three of them together and use a 20 HP outboard motor to control it. It wasn't very maneuverable, but it also didn't flip very often. Her trips were only about a week long and her passengers could take the train or bus to Flagstaff. She had been running these trips for about 15 years when I met her on my first Grand trip in 1969. Other outfitters began to use bridge pontoons in the early 1960s, and by the time GCNPS began to limit group size and the number of trips per day in the early 1970s, there were about twenty companies taking a total of 20,000 people per year through the Canyon. Rogue River Jetboat In addition to the Rogue River in Oregon, these boats are used on the Main Salmon, Snake and Colorado through Cataract Canyon, typically for one day trips. They were once used in the Grand Canyon both for up-runs and down-runs, but were outlawed by GCNPS in the early 1970s. Niagra Falls barrel Photoshop does have its uses. I put my son Travis in this wooden planter, then put a picture of him in a photo of Niagra Falls. He didn't even get wet :) Yangtze River “barrel” This is not Photoshopped picture. In 1986, the Chinese government gave a permit to an American to lead the first descent of the upper Yangtze. Four teams of Chinese were formed to beat the American to the first descent. By the time they reached Tiger Leaping Gorge in the Big Bend, several team members had drowned and the remaining two teams merged and built this inflated rubber ball to run the massive rapids of TLG. They succeeded in beating the American team to a first descent, but by the end of their trip a total of ten had drowned. The TV and press coverage of this race turned the Chinese off to rafting until a Chinese rafting team completed a first descent of the upper Yarlong Tsangpo without any loss of life. This river drains the north side of the Himalaya Mountains in southern Tibet, becoming the Bramaputra when it enters India. See next slide and go to https://www.youtube.com/watch?v=InCseMCuQLM for an incredible video of this craft running Tiger Leaping Gorge in the Great Bend of the Yangtze. Hutaio Shoal, Great Bend of Yangtze Taos Box experiment Hot air balloons do not make good whitewater craft. They can lift occupants over rapids, but have trouble making turns and tend to go upstream if the wind is blowing that way (a common occurrence). The whitewater boating industry was growing so fast that by the early 1970s one of larger companies, the American River Touring Association, started a whitewater school to train new guides. This is the cover of their first manual. Eventually the school and its manuals expanded, and of course other schools also began operating. International Scale of River Difficulty Class I – Easy, flat water, moving slowly Class II – Still easy, but with small rapids and faster flow Class III – For intermediate boaters – rapids require maneuvering but swims aren't that bad Class IV – For advanced boaters – waves are bigger, rocks are harder to avoid, boats may wrap on one, swimmers may hit rocks Class V – For expert boaters only – running rapids safely is challenging, flips are more common and bad swims can result in injury or death Class VI – For suicidal boaters only! River “Hole” Some holes can be fun to run, especially for kayakers and rafts that are large enough to “bridge” it. Others can cause flips, especially if run sideways, and some can be “keepers” of both boats and people, sometimes resulting in injury or death. The next few slides are from the manual and are self explanatory. River “Wrap” Bends and Ferrying Self explanatory. Daily flow info is available from USGS Water Resources for most popular river segments. Always wear a life jacket on whitewater rivers. The highest flow was about 300,000 cfs in 1892, though terrace gravels indicate flows of 800,000 in the past 2000 years, and many geologists believe it took thousands of muli-million cfs flows to carve the canyon. The gates to Glen Canyon Dam closed in 1963, so annual peak discharges are low, except for the 1983 flood of about 90,000 cfs. Boats flip frequently at flows above about 30,000 cfs – even 37' motorized rafts have flipped at high flows. Crystal Rapids in Grand Canyon Crystal is one of the longest and most challenging rapids in the Grand Canyon. Before Dec 1966, it was a small rapid, but a huge flash flood dumped large rocks into the river, creating a huge hole in the upper rapid and a rock island in the lower rapid. Crystal at 90,000 cfs in 1983 A Tour West motorized raft getting recycled in the upper hole. The trashed remains of the Tour West boat. The National Park Service closed the river to boating until the water level dropped as a result of this accident. Crystal's Rock Island at low water A 40' Western motor boat lost power and got hung up on the rock island, then an OARS 18' boat got hung up on the motor boat. A helicopter was required to free the boats. Strainer! Strainers (logs and trees) are one of the biggest hazards to whitewater boaters. They often appear as the spring floods decline and the first party to run the river has to be extremely careful. One of the best western kayakers, Walt Blackadar, drowned in one on the South Fork of the Payette in Idaho, a river he had run safely many times. Ropes can be saviors or killers. It's really important to avoid loose ropes on boats, as they tend to act like Anaconda snakes in the water and can cause you to drown. Skull Rapids – Westwater Canyon One of the sorriest drownings involving a loose bowline occurred at Skull Rapids when a boat being rowed by a highly experienced guide flipped at high water and the rope got wrapped around her disabled son's ankle. There's a 75' cliff on river right at the end of the rapid that has a big “cushion” with a large eddy called the “Room of Doom”, also bounded by cliffs, on the right. The boat tried to go left, into the main stream, but the Room of Doom eddy current caught the boy. Although his life jacket floated him, he was located in a spot where no one could reach him, and all the potential rescuers could do was watch him die of hypothermia. Kayakers were later able to free the body. Dubendorf Rapids in Grand Canyon Located about Mile 132, this is one of the major rapids in Grand Canyon. The left run is swimmable (I've done it on purpose, as have several of my friends), but the right side is not safe. Dory wrap on No-No run It's much better to flip in the tail waves of Deuby than to try cheating it on the right. I own a dory and avoiding rocks is very high priority. Wooden dories break up and aluminum and fiberglass dories wrap. There have been some spectacular dory wraps in Grand Canyon – the top of Hance, this one and one on the rock pile at the mouth of Havasu Creek. All of these required a helicopter for removal, a considerable expense for the owner, in addition to the total loss of the dory. Grand Canyon Dory Boatman Rowing a dory takes more skill than rowing a raft. First, they don't bounce, second they flip more easily. The result is that a Class III for a raft is often a Class IV for a dory, etc. Another consequence is that dory boatmen tend to have huge egos, at least until they've been humbled. Serious hypothermia in Cataract Fortunately, this raft and all occupants made it safely to shore. Needless to say, this was the end of the river trip. Unfortunately, it took two days to climb out of the canyon and another three to hike to their cars at the takeout. Long swims on rivers in spring when the water is cold is a significant cause of river deaths. Bears are generally only a hazard in campsites on rivers that are forested – especially the Rogue in Oregon and the Selway and the Middle Fork and Main Salmon in Idaho. It's important to clean up the kitchen and store all food in latched boxes at night. They can be scared away with a flash light, and if this doesn't work a Darth Vader sword should do the trick. Other hazards The most common causes of injury on river trips are on shore. Falls while climbing around camp or up side stream canyons cause far more injuries than swims. Rattlesnake bites are not common and don't cause death, but may cause loss of limb flexibility. Stings from scorpions and bits from red ants are usually just painful, but occassionally someone goes into anaphylactic shock, which can be fatal without evacuation to a hospital. Don't expect this vehicle to come to your rescue – it could take them a week or more to get to you, if at all. Plan on self rescuing, or hope another member of your group or another group can help. There are many river rescue books and classes and the American Canoe Association even certifies people with adequate training. These resources should be utilized. There are four types of river trips: commercial, regulatory (patrol), research (includes environmental) and private (non-commercial). I've done all four. On commercial trips, paid guides control the trip and do their best to make sure clients have such a great time that not only do they become repeat customers, but they tell their friends to join them next time. Patrol trips are necessary on rivers that are so popular that they can get crowded, so permits are required to limit the number of trips and river rangers check to make sure all trips have a permit and that they're following the environmental and safety regulations (though there are some great stories about sneak trips). Research trips include geology, ecology, archeology and other types of science. On private trips, people own their own boats, get a permit (if necessary) and take their friends along. “Pirate” trips are those where the private boat owners charge a fee rather than sharing costs. Usually private trips are also great trips, although sometimes friends of friends come along who aren't necessarily compatible people. In 1986 Ken Warren led a private trip on the Yangtze in western China and had a group of incompatible people (mostly caused by bad choices on Warren's part) and half of them mutinied, including some of the guides, which resulted in an early termination of the trip. Getting to the river can be hazardous This is the new I-17 bridge over the Agua Fria that washed away in a 1979 flood. Several cars were washed away. Statistics on deaths and injuries on river trip on an hourly basis indicate that driving to the river is more hazardous than floating it. Take baby steps The great majority of problems river runners can be avoided by learning the basics and avoiding running rivers above your skill level (and never during floods). Of course, as with all sports, there are extremists, and although they may have very high skill levels, they push limits and die at a higher rate than any other group of boaters. This is the cover to a coffee table book on whitewater rivers of the world by Graeme Addison. The following maps and images are from this book. Hooker River – New Zealand Thrombosis Falls, Mzimkula River Indus headwaters in Pakistan Zambezi in South Africa Hidden Falls, Tsangpo River in Tibet In 1998 two teams of boaters ran first descents of the Yarlung Tsangpo, which drains the north side of the Himalayas in Tibet. A Chinese rafting team ran the upper section, portaging two canyons (run later by foreigner kayakers), from the source to near the entrance to the Tsangpo Gorge, where the river flows through a 15,000' canyon before turning south around the east end of the Himalayas. An American team tried to run the Tsangpo Gorge in flood, with disastrous conseqences – one of them drowned, ending the attempt. A multinational team managed to kayak another 17 miles at low water in 2002 and ended up hiking to Hidden Falls, which had been discovered by Tibetan hunters centuries before and photographed by Chinese hikers in 1998. The 200' falls has never been run. Mekong headwaters on Tibetan Plateau This is me, rowing on a third descent of the Mekong headwaters. During the winter, at low water, the river freezes and Tibetans use it as a trail, painting manis (prayers) on rocks (they're partially submerged in this picture). Rio Claro Seven Tea Cups in Chile My son Travis, who owns a whitewater rafting business in China and runs the headwaters of the Yangtze and Mekong on the Tibetan Plateau and the Salween in southwest Yunnan, kayaked the Tea Cups after he graduated from highschool. Chorro Canyon, Naranja River Costa Rica My daughter Carmen worked as a guide on the Naranja after she graduated from highschool. Travis, her mother Cindy and I visited her and ran this Class V canyon. We went for several swims (a common occurrence) but the rapids are short drops followed by a pool, and the water is warm. Turnback Canyon, Alsek River, Canada Walt Blackadar was the first to kayak this canyon, and he did it solo. I took him on a Grand Canyon trip (he taught me to roll) and he ran Lava Falls four times, until he made it without having to roll. Google Earth image with popular rivers highlighted. The demand to run these is so high that private trip permits are required and commercial permits are limited. The following pictures are of famous rapids on these rivers. Rainie Falls, Rogue River in Oregon Oak Springs Rapids, Deschutes River in Oregon Dragon's Tooth Rapids, Klamath River in California Ladle Creek Rapids, Selway River in Idaho Salmon Falls, Salmon River in Idaho Quartzite Falls, Salt River in Arizona Warm Springs, Yampa River in Utah at 34,000 cfs in 1983 Lava Falls, Grand Canyon in Arizona Green River, Desolation Canyon in Utah Not everyone is a whitewater junkie. However, mosquitoes like flatwater, so unless there's some whitewater, you may suffer while floating through paradise. The San Juan is a Class II river, with enough riffles and small rapids to discourage mosquitoes. However, it's easy to get disoriented in the Goosenecks. Lots of boaters run rivers because they provide access great places for hikes. This is the top of the Mule Ear looking north at the San Juan River in southern Utah. Feather fetish, Hopi salt caves in Grand Canyon, Arizona Lots of rivers have interesting cultural aspects. This site is now off-limits to visitation, but there are hundreds of other sites worth hiking to. In fact, using the river to access remote archeological sites is one of the big attractions for many boaters. Illegal gold mining at Miner's Cabin Westwater Canyon in Utah Not everyone likes rivers. Nowadays, it's difficult to obtain permits to mine or engage in other types of activities that endanger the river, but that's only because river runners have had to become political activists to protect their favorite places. Palisade Whitewater Park plans, 2004 Since the 1990's, park 'n play whitewater parks near cities have become popular sites for kayakers. There are dozens in the US and hundreds worldwide. Unfortunately, in 2006 the US Bureau of Reclamation refused to issue permits to this one on the Colorado River near Grand Junction, Colorado. This map shows all of the dams in the Colorado River Drainage (red dots). It has been called “River No More” because only a small fraction of it reaches the Sea of Cortez – the rest evaporates from hydropower reservoirs, leaks into surrounding bedrock or is diverted for irrigation, industry or culinary uses. Steamboat Rock, Dinosaur NM in Utah This is the site of the infamous Echo Park Dam at the confluence of the Green and Yampa (upper right), which in the early 1960s the Sierra Club finally managed convinced Congress not to build. Glen Canyon Dam & Lake Powell Utah-Arizona The Sierra Club agreed not to fight Glen Canyon Dam as a compromise with the US Bureau of Reclamation for not building Echo Park Dam, in spite of a 1958 report by Luna Leopold, the first chief of the Division of Hydrology of the US Geological Survey, that stated the Colorado River did not have enough water for this dam. He has been proven right – Lake Powell, behind Glen Canyon, has averaged about 50% of its capacity for the past 15 years. So has Lake Mead, behind Hoover Dam. China is making the same mistake the US did – too many dams for the amount of water available, and it's going to get worse as the earth warms and precipitation patterns change. China is making another huge mistake by building about 140 large dams on the upper Yellow, Yangtze, Mekong, Salween and Indus in areas of high seismicity. Someday a large earthquake will topple a dam, and the flood will topple downstream dams. Get Involved in River Preservation and River Reclamation
