[20] Separate volcanic activity formed the northwestern portion of the plain, an area far from the path of the hotspot which now lies beneath Yellowstone National Park. [46] In December 2007, the U.S. Environmental Protection Agency (EPA) issued a permit requiring owners of fish farms along the Snake River to reduce their phosphorus discharge by 40%. In the 18th century, Shoshone territory extended beyond the Snake River Plain, extending over the Continental Divide into the upper Missouri River watershed and even further north into Canada. Scale [ca. Water diverted from the river for irrigation, after absorbing any surface pollutants, re-enters the ground and feeds the aquifer. Population density is based on the Earth at Night satellite imagery, cities white with red fringe, and darker grays for rural inhabited areas. The Snake River also shares a boundary with the Green River to the southeast; the Green River drains parts of Wyoming and Utah and is the largest tributary of the Colorado River. [95], Overall, these combined efforts have had good success. [26][28][29], The massive amounts of sediment deposited by the Lake Bonneville Floods in the Snake River Plain also had a lasting effect on most of the middle Snake River. Another place where pioneers crossed the Snake was further upstream, at a place called "Three Island Crossing", near the mouth of the Boise River. [62] A smallpox epidemic brought by European explorers and fur trappers was responsible for wiping out much of the Shoshone east of the Rocky Mountains, but the Shoshone continued to occupy the Snake River Plain. This map reflects just the major dams that have been constructed in the last century in the Columbia Basin. Early fur traders and explorers noted regional trading centers, and archaeological evidence has shown some to be of considerable antiquity. The largest tributary of the Columbia River, the Snake River watershed makes up about 41% of the entire Columbia River Basin. Later American explorers traveled throughout the Snake River area and up its major tributaries beginning in 1806, just after Lewis and Clark had returned. As the North American Plate moved westwards over a stationary hotspot beneath the crust, a series of tremendous lava flows and volcanic eruptions carved out the Snake River Plain beginning about 12 million years ago, west of the Continental Divide. Search; Images; Maps; Play; YouTube; News; Gmail; Drive; More. The watershed of the Grande Ronde in northeastern Oregon is also largely undeveloped. Hells Canyon Map - Snake River. South Fork of the Snake River Boat Access Map. Through Hell's Canyon you'll encounter set after set of large, voluminous rapids, Nez-Perce petroglyphs, homesteads, and wildlife of all sorts. Welcome to the Snake River google satellite map! The party later traveled north, descended the Lemhi River to the Salmon and attempted to descend it to the Snake, but found it impassable because of its violent rapids. The lake was stable and survived for nearly 30,000 years. Later American explorers, some of whom were originally part of the Lewis and Clark expedition, journeyed into the Snake River watershed and records show a variety of names have been associated with the river. The Nez Perce also were involved in trade with the Flathead tribe to the north and other middle Columbia River tribes. Above the falls, life was significantly different. The mollusc richness extends into the lower Columbia River and tributaries such as the Deschutes River. Salmon can travel up the Snake River as far as Hells Canyon Dam, using the fish passage facilities of the four lower Snake River dams, leaving the Clearwater, Grande Ronde and Salmon river to sustain spawning salmon. [83] However, there were more resources along the Snake River than wheat and grain. On the south, the Snake watershed borders that of the Humboldt River in Nevada, and the watershed of the Great Salt Lake (the Bear, Jordan and Weber rivers) on the south. The first studies for irrigation in the Snake River Plain were conducted by the United States Geological Survey in the late 19th century, and the project was authorized on April 23, 1904. On the western extremity for a short stretch the Continental Divide separates the Snake watershed from the Bighorn River, a tributary of the Yellowstone River, which the Snake begins near. Compared to the lower Snake River and the rest of the Columbia River's watershed, the Upper Snake ecoregion has a high level of endemism, especially among freshwater molluscs such as snails and clams. Get directions, maps, and traffic for Snake River, WA. [25] The Bonneville flood waters continued through Hells Canyon and eventually reached the Columbia River. [3] Eventually, the name Snake River was derived from an S-shaped gesture the Shoshone tribe made with their hands to represent swimming salmon. The lower Snake River also supports seven species of Pacific salmon and trout (Oncorhynchus). This comprehensive PDF guides include river maps, overview, full itineraries, camping and weather information, details on physical requirements, packing lists and more. CONTACT INFO. Hells Canyon Dam was the last and most downriver of the three. Major cities along the river include Jackson in Wyoming, Twin Falls, Idaho Falls, Boise, and Lewiston in Idaho, and the Tri-Cities in Washington (Kennewick, Pasco and Richland). [78] This stretch of the river is the easiest to navigate for watercraft since it has the least elevation change, although it still contained over 60 sets of rapids. The source of the Snake River was debated for a long time. They also made note of the "Snake Indians" who lived along the river, who were actually the Shoshonetribe, and learned that the Nati… [94], Another interesting recovery method conservationists and biologists are using is called Fish Transportation. In the upper parts of the watershed, however, the river flows through an area with a distinct alpine climate. Several ships were built specifically to transport ore from there to Lewiston: these included Imnaha, Mountain Gem, and Norma. At one point, sign language used by the Shoshones representing weaving baskets was misinterpreted to represent a snake, giving the Snake River its name.[10]. It is of note that the northeastern divide of the Snake River watershed forms the Idaho-Montana boundary, so the Snake River watershed does not extend into Montana. The confluence of the Snake and Columbia rivers at Burbank, Washington is part of Lake Wallula, the reservoir of McNary Dam. [105], A controversy has erupted since the late 20th century over the four lower Snake River dams, with the primary argument being that removing the dams would allow anadromous fish to reach the lower Snake River tributaries—the Clearwater River, the Tucannon River and the Grande Ronde River—and spawn in much higher numbers. At 1,078 miles (1,735 km) long, it is the largest tributary of the Columbia River, in turn the largest North American river that empties into the Pacific Ocean. This spectacular and informative South Fork of the Snake River Paper Fishing & Fly Fishing Map covers the South Fork of the Snake River from Palisades Reservoir to the Menan Boat Access in Idaho. The nearly complete subduction of the Farallon Plate underneath the westward-moving North American Plate created the Rocky Mountains, which were pushed up by rising magma trapped between the sinking Farallon plate and the North American plate. * Call (888) 749-5280 or your travel professional. One contemporary diarist crossing near Salmon Falls complains of "exorbitant" fees at the crossings that were a "constant drain" on the travelers purse. Prehistoric Native Americans lived along the Snake starting more than 11,000 years ago. Barrow's goldeneye are a species of bird that occurs commonly along the lower section of the Snake River. In Hells Canyon, a cascade of dams produce hydroelectricity from the river's steep fall over a comparatively short distance. Starting in the 1890s, fifteen major dams have been built on the Snake River to generate hydroelectricity, enhance navigation, and provide irrigation water. Directly below the confluence, the river flows into Lower Granite Lake, formed by Lower Granite Dam, the uppermost dam of the Lower Snake River Project. Lava flowing from Cedar Butte in present southeast Idaho blocked the Snake River at Eagle Rock about 42,000 years ago, near the present-day site of American Falls Dam. The removal of several dams on the lower Snake River has been proposed, in order to restore some of the river's once-tremendous salmon runs. She writes that this particular route was controlled by Mormons who had "built bridges where they were not needed-most unmercifully fleecing the poor emigrants". The Salmon River is the second largest tributary.

[84] In 1893 the Annie Faxon suffered a boiler explosion and sank on the Snake below Lewiston.[78][85]. Sophistication varied from reed boats pulled by Indians on horse back at Snake Fort, Fort Boise, as described by Narcissa Whitman[74] in 1836 to an electric operated ferry, the Swan Falls Ferry,[75] at Swan Falls Dam of the early 20th century. The Snake River Plain forms one of the only relatively easy paths across the main Rocky Mountains for many hundreds of miles, allowing Native Americans both east and west of the mountains to interact. Many of the rivers that flow into the Snake River Plain from the north sink into the Snake River Aquifer, but still contribute their water to the river. [9] The Snake River rises in western Wyoming, then flows through the Snake River Plain of southern Idaho, the rugged Hells Canyon on the Oregon–Idaho border and the rolling Palouse Hills of Washington, emptying into the Columbia River at the Tri-Cities, Washington. Snake River Valley is a valley in Idaho and has an elevation of 4364 feet. The mostly semi-arid, even desert climate of the Snake River watershed on average, receives less than 12 inches (300 mm) of precipitation per year. Later explorers and fur trappers further changed and used the resources of the Snake River basin. North of Boise, the Snake enters Hells Canyon, a steep, spectacular, rapid-strewn gorge that cuts through the Salmon River Mountains and Blue Mountains of Idaho and Oregon. The Snake River's annual salmon run, which was estimated at that time to exceed four million in good years, supported the Nez Perce, who lived in permanent, well-defined villages, unlike the nomadic southeastern tribes along the Snake River. Map of the sources of Snake River : with its tributaries together with portions of the headwaters of the Madison and Yellowstone from surveys and observations of the Snake River Expedition Contributor Names Bechler, Gustavus R. Hayden, F. V. (Ferdinand Vandeveer), 1829-1887. [19] Even larger lava flows of Columbia River basalts issued over eastern Washington, forming the Columbia Plateau southeast of the Columbia River and the Palouse Hills in the lower Snake. The explorer Wilson Price Hunt of the Astor Expedition named the river as Mad River. Most of the Snake River watershed lies between the Rocky Mountains on the east and the Columbia Plateau on the northwest. [7] The highest flow ever recorded on the Snake River was at a different USGS stream gauge near Clarkston, which operated from 1915 to 1972. Another conservation effort that has helped the salmon recover, is the destruction of old, outdated dams, such as the Lewiston Dam on the Clearwater River, a tributary of the Snake. The Snake River likely got its name from the first European explorers who misinterpreted the sign made by the Shoshone people who identified themselves in sign language by moving the hand in a swimming motion which appeared to these explorers to be a \"snake.\" It actually signified that they lived near the river with many fish. Still, from the 1860s to the 1940s, steamboats traveled on the Snake River from its mouth at the Columbia River to near the mouth of the Imnaha River in lower Hells Canyon. Where river depths were less than 14 feet (4 m), the shipping channel has been dredged in most places. These baby salmon then are transported by ship, bypassing the dams. For other uses, see, Major river in the northwestern United States, Lewis River, Shoshone River, Mad River, Saptin River, Yam-pah-pa, Lewis Fork. [97] With a channel about 5 feet (1.5 m) deeper than the Mississippi River system, the Columbia and Snake rivers can float barges twice as heavy. Since many juvenile salmon perish at each dam while swimming out to the ocean, massive ships filter and collect these baby salmon by size and take them out to the ocean for a ride, where they can be guaranteed to make it alive to saltwater. In higher elevations, conifer forests, of which ponderosa pine is most common, dominate the landscape. Includes "Time rock chart, " explanation of color shading and symbols used on map, and 3 geologic cross sections The Snake River watershed includes parts of Yellowstone National Park, Grand Teton National Park, Hells Canyon National Recreation Area, and many other national and state parks. [64] Meriwether Lewis supposedly became the first American to sight the drainage basin of the Snake River after he crossed the mountains a few days ahead of his party on August 12, 1805, and sighted the Salmon River valley (a major Snake tributary) from Lemhi Pass, a few miles from the present-day site of Salmon, Idaho. Location: Lake West, Snake River Mile 66, South River Bank Acreage: 113 Acres Highway Directions: 6 miles northeast of Starbuck, Washington, on Little Goose Dam Road, 2 miles west of Little Goose Dam. Runoff from several feedlots was dumped into the river until laws made the practice illegal. Instead most individuals misidentify the harmless water snake as a cottonmouth. It is interrupted by several major cataracts, the largest being 212-foot (65 m) Shoshone Falls, which historically marked the upriver limit of migrating salmon. The diarist expresses regret at having made the crossing describing the landscape as "desolate country". It is known that before the construction of dams on the river, there were three major chinook salmon runs in the Snake River; in the spring, summer and fall, totaling about 120,000 fish, and the sockeye salmon run was about 150,000. 945 West Broadway, Jackson, WY On August 27, 1965, there was temporarily no flow as a result of testing at Ice Harbor Dam. Salmon swimming upstream in this river are faced with predators and dams. This mountainous gorge forms the border between Oregon and Idaho, and part of Washington. Pollutant levels in Hells Canyon upstream of the Salmon River confluence, including that of water temperature, dissolved nutrients, and sediment, are required to meet certain levels. At its height, there were at least 27 Nez Perce settlements along the Clearwater River and 11 more on the Snake between the mouth of the Clearwater and Imnaha Rivers. The United States Geological Survey recorded the river's discharge from a period of 1963–2000 at a stream gauge below Ice Harbor Dam. The first was John Ordway in 1806, who also explored the lower Salmon River. The Portneuf River Valley is an overflow channel that in the last glacial period carried floodwaters from pluvial Lake Bonneville into the Snake River, significantly altering the landscape of the Snake River Plain through massive erosion. (McNary Dam is not part of the Lower Snake River Project.) [65][66] The name "Lewis Fork", however, did not last.[64]. At Twin Falls, in the center of the Snake River Plain, the climate is nearly desert, with an annual rainfall of just 9.24 inches (235 mm), although the average snowfall is 13.1 inches (330 mm). [25] Much of the water lost by the Snake River as it transects the plain issues back into the river at its western end, by way of many artesian springs. [86] Detailed map of the South Fork of the Snake River (in idaho). Above Jackson Lake, Wyoming, the discharge is about 885 cu ft/s (25.1 m3/s) from a drainage area of 486 square miles (1,260 km2). In the 1950's, the name \"Hells Canyon\" was borrowed from Hells Canyon Creek, which enters the rive… During this period people drew upon a wide variety of food resources. [45] Throughout much of the Snake River Plain and Hells Canyon, excessive sediment is also a recurring problem. That doesn't mean you will not see a snake in your yard; just that it is less likely. The flood widened Hells Canyon but did not deepen it. Be sure to use the arrows to scroll to 2022. [101], Aside from aquatic species, much of the Snake River watershed supports larger animals including numerous species of mammals, birds, amphibians, and reptiles. Water in the aquifer eventually travels to the west side of the Snake River Plain and re-enters the river as springs. [101], The Snake River below Shoshone Falls is home to thirty-five native fish species, of which twelve are also found in the Columbia River and four of which are endemic to the Snake: the relict sand roller (Percopsis transmontana) of the family Percopsidae, the shorthead sculpin (Cottus confusus), the maginated sculpin (Cottus marginatus), and the Oregon chub (Oregonichthys crameri). There were also villages on the Salmon River, Grande Ronde River, Tucannon River, and the lower Hells Canyon area. But each island may have some slightly different rules that apply to public use because of the mix of ownership and location that affect jurisdictional issues. Another writer similarly notes several days travel through "a desert so desolate and rocky that we almost regretted that we had not continued on the south side of that stream". As recently as 165 million years ago, most of western North America was still part of the Pacific Ocean. That depends largely upon the location of your home. Especially in the headwaters and the other mountainous areas strewn throughout the watershed, the gray wolf, grizzly bear, wolverine, mountain lion and Canada lynx are common. Adventure Travel Web Design by Canyons Digital. Irrigators in the Snake River Plain would likely need to allow less water into the Snake River during low flow in order to create a current in the four lower reservoirs, and recreation and tourism would likely benefit.[109]. Many different government and private agencies have worked to build dams on the Snake River, which now serve an important purpose for people living in the drainage basin and trade of agricultural products to Pacific seaports. Eventually, the Shoshone culture merged with that of the Paiute and Bannock tribes, which came from the Great Basin and the Hells Canyon area, respectively. [3], Agricultural runoff from farms and ranches in the Snake River Plain and many other areas has severely damaged the ecology of the river throughout the 20th century. However, they were enemies to the Shoshone and the other upstream Snake River tribes. When the Teton Range uplifted about 9 million years ago along a detachment fault running north–south through the central Rockies,[21] the river maintained its original course and cut through the southern end of the mountains, forming the Snake River Canyon of Wyoming. However, aside from restoring salmon runs, dam removal proponents argue that the power is replaceable, that the grain transportation system could be replaced by railroads, and that only one of the four reservoirs supplies irrigation water. Irrigation dams include American Falls Dam, Minidoka Dam, and C.J. Irrigation pumps for fields in southeastern Washington would also have to reach further to access the water of the Snake River. Between here and Hells Canyon, the first dam on the Snake, Swan Falls Dam, was built in 1901. *Terms and Conditions The Snake River from its source to Jackson Lake, from one mile downstream of Jackson Lake Dam to one mile downstream of the Teton Park Road Bridge at Moose, Wyoming, and from the mouth of the Hoback River to the point one mile upstream from the Highway 89 Bridge at Alpine Junction. This mountainous gorge forms the border between Oregon and Idaho, and part of Washington. Includes boat access points, campgrounds, and great views of the roads available. If you back up to a river or creek, or one is within a mile of your home, the likelihood of seeing a snake or coming upon one is greater than if you live in the middle of your subdivision. The Hells Canyon Project was built and maintained by Idaho Power Company starting in the 1940s, and was the second of the three major water projects on the river. Headwaters of the North Fork are at Big Springs near Island Park, Idaho, while Jackson Lake is at the head of the South Fork. In the lowermost part of the watershed, in southeastern Washington, the Snake River is surrounded by an area called the Columbia Plateau Ecoprovince, which is now mostly occupied by irrigated farms. Thus a deep shipping channel through locks and slackwater reservoirs for heavy barges exists from the Pacific Ocean to Lewiston, Idaho. Many rivers and streams flowing from the north side of the plain sink into the aquifer instead of flowing into the Snake River, a group of watersheds called the lost streams of Idaho. Here the Snake River almost doubles in size as it receives several major tributaries – the Owyhee from the southwest, then the Boise and Payette rivers from the east, and further downstream the Malheur River from the west and Weiser River from the east. 325 miles (523 km) below the Snake confluence comes from river mileage markers on USGS topo maps. The Grand Coulee Dam also blocks spawning grounds to the famous "June Hogs" (legendary Chinook salmon that weighed over 100 pounds [45 kg]). [58][59], On the Snake River in southeastern Washington there are several ancient sites. [8], The river's flow is also measured at several other points in its course. Formed by the confluence of three tiny streams on the southwest flank of Two Oceans Plateau in Yellowstone National Park, western Wyoming, the Snake starts out flowing west and south into Jackson Lake. [43] Fertilizer, manure and other chemicals and pollutants washed into the river greatly increase the nutrient load, especially of phosphorus, fecal coliforms and nitrogen. After the first irrigation dams on the river began operation in the first decade of the 20th century, much of the arable land in a strip a few miles wide along the Snake River was cultivated or turned to pasture, and agricultural return flows began to pollute the Snake. The Wood River sculpin (Cottus leiopomus) is endemic to the Wood River. [18][105], At the confluence of the Snake and Clearwater Rivers, young salmon that swim down from spawning gravels in the headwaters of the Clearwater River often delay their migrations because of a significant temperature difference. Upstream Columbia mileage calculated by subtracting 325 (Snake River confluence mile) from 1243 (the length of the Columbia). It is characterized by large horse-mounted tribes that spent long amounts of time away from their local foraging range hunting bison. [39] Most of the Snake River basin consists of wide, arid plains and rolling hills, bordered by high mountains. The second period, "Semisedentary Foraging", dates from 4,200–250 years before present and is distinctive for an increased reliance upon fish, especially salmon, as well as food preservation and storage.

"[69] Their goal was to eventually gain rights over the Oregon Territory, a region covering Washington, Oregon, Idaho, and parts of Montana and Wyoming (most of the present-day region called the Pacific Northwest). [23] This was one of the first in a series of catastrophic flooding events in the Northwest known as the Ice Age Floods. According to legend, the Nez Perce tribe was first founded in the valley of the Clearwater River, one of the Snake River's lowermost major tributaries. The deluge caused American Falls Lake to breach its natural lava dam, which was rapidly eroded with only the 50-foot-high (15 m) American Falls left in the end. Hell's Canyon Dam blocks passage to the entire upper Snake River. Steamboats and railroads moved agricultural products and minerals along the river throughout the 19th and early 20th centuries. However, in the high Rockies of Wyoming, in the upper Jackson Hole area, the average precipitation is over 30 inches (760 mm), and snowfall averages 252 inches (6,400 mm). [81] The Oregon Steam Navigation Company launched the Shoshone at Fort Boise in 1866 which provided passenger and freight service on the upper Snake for the Boise and Owyhee mines. Riparian zones, wetlands and marshes once occurred along the length of the Snake River and its tributaries. Thompson, and Wide West, all of which were built on the Columbia River. Strike Dam. [44], Much of the return flows do not issue directly back into the Snake River, but rather feed the Snake River Aquifer underneath the Snake River Plain. Engineers at Whooshh Innovations have developed a fish passage system that allows for the safe and timely transportation of fish over barriers through a flexible tube system via volitional entry into the system. [87] The first dam constructed for the project was Minidoka Dam in 1904; its power plant began operating in 1909, producing 7 MW of electricity. A map of the Columbia River watershed with the Snake River highlighted in yellow and the Columbia River highlighted in blue. Dams on the Snake can be grouped into three major categories. In the 1890s, a huge copper deposit was discovered at Eureka Bar in Hells Canyon. [12], The Snake River was once one of the most important rivers for the spawning of anadromous fish—which are hatched in the headwaters of rivers, live in the ocean for most of their lives, and return to the river to spawn—in the United States. The Snake River originates in Wyoming and arcs across southern Idaho before turning north along the Idaho-Oregon border. Find local businesses, view maps and get driving directions in Google Maps. There are fifteen dams in total along the Snake River, which aside from irrigation, also produce electricity, maintain a navigation channel along part of the river's route, and provide flood control. The shipping channel is authorized to be at least 14 feet (4 m) deep and 250 feet (76 m) wide. At the base of mountains and in the Lost River basin, sagebrush was and is the predominant vegetation cover. Lake Idaho, formed during the Miocene, covered a large portion of the Snake River Plain between Twin Falls and Hells Canyon, and its lava dam was finally breached about 2 million years ago.[22]. [102], The Snake River watershed includes a diversity of vegetation zones both past and present. [52] At Anatone, Washington, downstream of the confluence with the Salmon, one of the Snake's largest tributaries, the mean discharge is 34,560 cu ft/s (979 m3/s). The expedition named the Snake River the Lewis River, Lewis's River, or Lewis Fork, in his honor, and they traveled northwards to the Lochsa River, which they traveled via the Clearwater River into the lower Snake, and into the Columbia. The Snake River Plain was created by a volcanic hotspot which now lies underneath Yellowstone National Park, where the headwaters of the Snake River arise. The reason for the Three Island Crossing was the better availability of grass and water access. As a result, the Shoshone centered on a trading economy. The Snake River drainage basin encompasses parts of six U.S. states (Idaho, Washington, Oregon, Utah, Nevada, and Wyoming) and is known for its varied geologic history. Donald Mackenzie sailed the lower Snake River in 1811, and later explorers included Wilson Price Hunt of the Astor Expedition (who gave the river the name "Mad River"),[68] Ramsay Crooks, Francisco Payelle, John Grey, Thyery Goddin, and many others after the 1830s. In the 1960s and 1970s the U.S. Army Corps of Engineers built four dams and locks on the lower Snake River to facilitate shipping. The first he calls "Broad Spectrum Foraging", dating from 11,500 to 4,200 years before present. [38] This desert climate occupies the majority of the basin of the Snake River, so although it is longer than the Columbia River above the Tri-Cities, its discharge is on average significantly less.
