178-590: The Fort Hall Reservation is a Native American reservation of the federally recognized Shoshone - Bannock Tribes ( Shoshoni language : Pohoko’ikkatee ) in the U.S. state of Idaho . This is one of five federally recognized tribes in the state. The reservation is located in southeastern Idaho on the Snake River Plain about 20 miles (32 km) north and west of Pocatello . It comprises 814.874 sq mi (2,110.51 km) of land area in four counties: Bingham , Power , Bannock , and Caribou . To

356-611: A Shoshone war party attacked a wagon train in the Boise Valley, and the U.S. Army mounted a counterattack, the Winnas Expedition . The situation became so unstable that Fort Boise was abandoned, and the Army had to escort wagon trains through the area. While early settlers had simply passed through this area on their way to Oregon, gold strikes brought renewed interest in the 1860s. The Army rebuilt Fort Boise further east of

534-468: A central role in the culture and diet of indigenous peoples. The Shoshone and Nez Perce were the largest of several tribes that lived along the river by the turn of the 19th century. In 1805, while searching for a route from the eastern US to the Pacific, Lewis and Clark became the first non-natives to see the river. Fur trappers explored more of the watershed, and drove beaver to near extinction as

712-463: A common constitution and established their own elected government. They have managed to retain most of their lands since that time. During World War II , however, the US government assumed control of a 3,300-acre tract within the reservation, which it developed for use as an air base. Federal officials had told the tribe they would return the land to them after the war. Instead, the federal government sold

890-1011: A conviction that carries an appropriate potential sentence when a serious crime has been committed. Our role as the primary prosecutor of serious crimes makes our responsibility to citizens in Indian Country unique and mandatory. Accordingly, public safety in tribal communities is a top priority for the Department of Justice. Emphasis was placed on improving prosecution of crimes involving domestic violence and sexual assault. Passed in 1953, Public Law 280 (PL 280) gave jurisdiction over criminal offenses involving Indians in Indian Country to certain States and allowed other States to assume jurisdiction. Subsequent legislation allowed States to retrocede jurisdiction, which has occurred in some areas. Some PL 280 reservations have experienced jurisdictional confusion, tribal discontent, and litigation, compounded by

1068-422: A few cases voluntary moves based on mutual agreement. The removal caused many problems such as tribes losing the means of livelihood by being restricted to a defined area, poor quality of land for agriculture, and hostility between tribes. The first reservation was established by Easton Treaty with the colonial governments of New Jersey and Pennsylvania on August 29, 1758. Located in southern New Jersey , it

1246-756: A five-year approval before 1850. Article two of the treaty claims "the reserves on the river Angrais and at Rifle river, of which said Indians are to have the usufruct and occupancy for five years." Indigenous people had restraints pushed on them by the five-year allowance. Scholarly author Buck Woodard used executive papers from Governor William H. Cabell in his article, "Indian Land sales and allotment in Antebellum Virginia" to discuss Indigenous reservations in America before 1705, specifically in Virginia. He claims "the colonial government again recognized

1424-709: A forced mass migration that came to be known as the Trail of Tears . Some of the lands these tribes were given to inhabit following the removals eventually became Indian reservations. In 1851, the United States Congress passed the Indian Appropriations Act which authorized the creation of Indian reservations in Indian Territory (which became Oklahoma). Relations between white settlers and Natives had grown increasingly worse as

1602-524: A large network of canals and pump stations. The Minidoka Project would eventually bring water to a million acres (2,500 km ) of the Magic Valley. During World War II, many Japanese Americans interned at Minidoka were made to work on the project. The Boise Project , which would ultimately water 500,000 acres (200,000 ha) in and around the Boise Valley, was another major early reclamation undertaking. At its completion, Arrowrock Dam (1915) on

1780-489: A lighthouse. The President of the United States of America was directly involved in the creation of new treaties regarding Indian Reservations before 1850. Van Buren stated that indigenous reservations are "all their reserves of land in the state of Michigan, on the principle of said reserves being sold at the public land offices for their benefit and the actual proceeds being paid to them." The agreement dictated that

1958-682: A natural glacial lake enlarged by Jackson Lake Dam . It flows south through the alpine valley of Jackson Hole , which is situated between the Teton Range (to the west) and the Gros Ventre Range . Below the town of Jackson it forms the Snake River Canyon of Wyoming , turns west and crosses into Idaho , where the Palisades Dam forms Palisades Reservoir . From there it flows northwest through Swan Valley to join

2136-484: A new property at the airport. The tribe was consulted by FAA officials, who are handling the environmental assessment for the project, but they learned that the company was prohibited by the city from entering into any written agreement with the tribes. They are worried about getting stuck with an operation that could cause environmental damage. In the 21st century, the tribes employ nearly 1,000 Native and non-Native people in various trades: 575 in tribal government, 85 by

2314-663: A policy of reconciliation with the Shoshone. But other settlers complained, and the federal government ordered the U.S. Army into the Utah Territory in 1858, resulting in full-scale conflict between the U.S. and the Shoshone. There had been escalating conflicts, with the Shoshone and Bannock tribes pitted against the increasing tide of European-American settlers. The latter encroached on the Native Americans' traditional territory, competing for resources and damaging

2492-574: A rapid, forcing their retreat. On the Snake River above Hells Canyon, several steamboats were built at great expense (as manufactured parts such as engines had to be hauled in overland), the first being the Shoshone in 1866. However, running the upper Snake proved unprofitable, due to lack of demand. The owners of Shoshone decided to move her to the lower Snake River, and in April 1870, they made

2670-589: A series of disputes over sovereignty. Snake River The river's watershed , which drains parts of six U.S. states , is situated between the Rocky Mountains to the north and east, the Great Basin to the south, and the Blue Mountains and Oregon high desert to the west. The region has a long history of volcanism ; millions of years ago, Columbia River basalts covered vast areas of

2848-581: A series of massive flood basalt events that engulfed the Columbia Basin and surrounding lands, reshaped the landscape and erased most evidence of the pre-volcanic river channels starting about 17 Ma. Erupting from fissures in the southern Columbia Basin, the first basalt flows pushed the ancient Salmon-Clearwater much further north than its present course. About 12–10 Ma, the Blue Mountains region began to experience uplift, raising

3026-619: A seven-member elected council and maintain their own governmental services, including law enforcement, courts, social and health services, and education. The four other federally recognized tribes in the state are the Coeur d'Alene , Kootenai , Nez Perce , and Shoshone-Paiute at Duck Valley Indian Reservation . In July 2016, the Department of Interior made offers to 536 landowners with fractional interests at Fort Hall Reservation for buy-back of lands valued at $ 11 million in offers. This

3204-478: A steep grade, was connected three years later. In addition to commerce, the railroad also opened the Snake River region – which just a few years ago had been seen as a remote, rough frontier – to recreation. The Union Pacific heavily promoted tourism in places like Shoshone Falls, Payette Lake and Soda Springs, Idaho . Countering the reputation of southern Idaho as a wasteland, a brochure described Shoshone Falls: "Shoshone differs from every other waterfall in this or

3382-523: A third of the discharge at the mouth. Just two downstream tributaries, the Clearwater and Salmon Rivers, contribute about half of the total flow of the Snake. The 107,500-square-mile (278,000 km ) Snake River watershed drains about 87 percent of the state of Idaho, 18 percent of Washington and 17 percent of Oregon, in addition to small portions of Wyoming, Utah and Nevada . From

3560-754: Is 212-foot (65 m) Shoshone Falls , which in the spring flows with such force that 19th-century writers called it the "Niagara of the West". The Snake River continues flowing west, through the C. J. Strike Reservoir where it is joined from the left by the Bruneau River , then through the Morley Nelson Snake River Birds of Prey National Conservation Area before entering farmland on the western side of Idaho's Treasure Valley . Passing 30 miles (48 km) west of Boise , it crosses briefly into Oregon before turning north to form

3738-487: Is 56,200,000 acres (22,700,000 ha; 87,800 sq mi; 227,000 km ), approximately 2.3% of the total area of the United States and about the size of the state of Idaho . While most reservations are small compared to the average U.S. state, twelve Indian reservations are larger than the state of Rhode Island . The largest reservation, the Navajo Nation Reservation , is similar in size to

Tribal citizens may utilize several resources held in tribal tenures such as grazing range and some cultivable lands. They may also construct homes on tribally held lands. As such, members are tenants-in-common , which may be likened to communal tenure. Even if some of this pattern emanates from pre-reservation tribal customs, generally

4094-565: Is a legal designation. It comes from the conception of the Native American nations as independent sovereigns at the time the U.S. Constitution was ratified. Thus, early peace treaties (often signed under conditions of duress or fraud), in which Native American nations surrendered large portions of their land to the United States, designated parcels which the nations, as sovereigns, " reserved " to themselves, and those parcels came to be called "reservations". The term remained in use after

The final stretch of the Snake River flows through steep-sided valleys in the Palouse Hills of southeast Washington. Near Lyons Ferry State Park , it is joined from the left by the Tucannon River , then from the right by the Palouse River , which forms Palouse Falls about 8 miles (13 km) upstream of its confluence with

4806-858: Is primarily sagebrush , mixed with wheatgrasses and bunchgrasses . About 30 percent of the watershed is farmland; irrigated farming of potatoes, sugar beets, onions, cereal grains and alfalfa are dominant in the Snake River Plain, while the Palouse Hills of the northwest host mainly dryland wheat and legume production. About 15 percent of the watershed is forested, distributed across two temperate coniferous forest ecoregions : South Central Rockies forests , consisting primarily of Douglas fir , Engelmann spruce , subalpine fir , and lodgepole pine , and North Central Rockies forests , which include mountain hemlock , white spruce , alpine fir and western larch . About 4 percent of

The J.R. Simplot Company also operated on and near the reservation for decades. Their sites have been designated by the EPA as Superfund sites. Although some mitigation has been accomplished, scientists estimate

5162-817: The Bitterroot Range along the Idaho–Montana border. The Blue Mountains form much of the western boundary of the Snake watershed from southeast Washington down into Oregon. To the south are numerous small isolated mountain ranges of the Basin and Range Province , such as the Independence and Albion Mountains . To the east are more ranges of the Rockies including the Tetons and the Wind River Range ;

5340-462: The Blue Mountains of Oregon and Washington. The Hells Canyon Hydroelectric Complex includes the Brownlee , Oxbow and Hells Canyon Dams in the upper reaches of the canyon. Since its construction in 1967, Hells Canyon Dam has been the upriver limit for migrating salmon; in the past, salmon swam as far upriver as Shoshone Falls. Emerging from Hells Canyon Dam, the Snake surges northward through

Both the Nez Perce and Shoshone acquired horses in the late 1600s or early 1700s, enabling far-reaching trade and hunting expeditions. With horses, the Nez Perce were able to travel east of the Bitterroot Mountains to hunt bison, via the trail over Lolo Pass , which

It absorbs and stores large volumes of water from the Snake River in the eastern Plain to re-emerge further west as springs in the Snake River Canyon. Water from the lost streams of Idaho , several rivers that disappear underground in the eastern Plain, travels through

In 1877 the US government attempted to force the remaining Nez Perce onto their reservation, at which point Chief Joseph's band and several others opted to seek refuge elsewhere. After a treacherous crossing of the Snake at Dug Bar, Hells Canyon on May 31, the Nez Perce were pursued by

A third act pushed through was "the federal government relocated "portions of [the] 'Five Civilized Tribes' from the southeastern states in the Non-Intercourse Act of 1834 ." All three of these laws set into motion the Indigenous Reservation system in the United States of America, resulting in the forceful removal of Indigenous peoples into specific land Reservations.

This crossed the Snake River by the Eagle Rock Ferry and later a bridge which the city of Idaho Falls would soon grow around. As the flow of settlers increased, the Nez Perce and their neighbors the Cayuse and Walla Walla came under pressure to cede portions of their territory. Tensions flared in 1855 after tribes were coerced into relinquishing huge amounts of territory in

The following year, Mackenzie traveled up the Snake River and reached Boise Valley by making the first recorded river ascent of Hells Canyon. Mackenzie's goal was to bypass the arduous trek over the Blue Mountains. He wrote that "the passage by water is now proved to be safe and practicable for loaded boats, without one single carrying place or portage; therefore,

The Trade and Intercourse Act of 1834 says "In the 1834 Indian Trade and Intercourse Act, the United States defined the boundaries of Indian County." Also, "For Unrau, Indigenous Country is less on Indigenous homeland and more a place where the U.S. removed Indians from east of

8010-490: The 1855 treaty. The US government sided with the settlers, and pressured some Nez Perce leaders into signing a second treaty which shrank their reservation by 90 percent. Many Nez Perce including Chief Joseph 's band refused to leave, calling the new treaty the "thief treaty". In March 1863, the Idaho Territory was split from Oregon, and Lewiston became its capital. More than 60,000 prospectors and others entered

From American Falls it turns west, flowing through Minidoka Dam and Milner Dam , where large volumes of water are diverted for irrigation. Below Milner Dam it enters the Snake River Canyon of Idaho , where the river narrows, forming rapids and waterfalls. In the 70-mile (110 km) stretch between Milner Dam and

8366-529: The 326 Indian reservations in the United States , while some share reservations, and others have no reservation at all. Historical piecemeal land allocations under the Dawes Act facilitated sales to non–Native Americans, resulting in some reservations becoming severely fragmented, with pieces of tribal and privately held land being treated as separate enclaves. This intersection of private and public real estate creates significant administrative, political, and legal difficulties. The total area of all reservations

8544-434: The Americans and British vied for control of Oregon Territory . Although travelers on the Oregon Trail initially shunned the dry and rocky Snake River region, a flood of settlers followed gold discoveries in the 1860s, leading to decades of military conflict and the eventual expulsion of tribes to reservations. At the turn of the 20th century, some of the first large irrigation projects in the western US were developed along

On October 5, 1877, Chief Joseph surrendered to US forces. thus ending the Nez Perce War . The survivors were distributed to various reservations across the western US. In 1878, an uprising occurred in response to overcrowding and food shortages at

A group led by Robert Stuart , a member of the Hunt expedition, returned eastward across the plain the following year. The route they mapped would eventually become that section of the Oregon Trail . In 1818 Donald Mackenzie and Alexander Ross established Fort Nez Percés for

9078-479: The Boise Project. Palisades Dam was built in 1956, providing flood control and irrigation for the Snake River above Idaho Falls, an area which the Bureau of Reclamation had previously overlooked. Near Rexburg, the Teton Dam was also built to provide water for this area. In 1976, the Teton Dam failed catastrophically, killing eleven people and causing at least $ 400 million in damage along the Henrys Fork and Snake Rivers. The political fallout from this disaster marked

9256-435: The Boise River was the tallest dam in the world, and its construction process was an important prototype for future federal projects such as Hoover Dam . Starting around the 1950s, farmers made heavy use of the Snake River aquifer, bringing large new areas into production. Surface water development also increased with projects such as Cascade Dam (1948) and Anderson Ranch Dam (1950), which provided additional storage for

9434-432: The Boise Valley, and a new city quickly grew around the U.S. Army post at Fort Boise. With Hells Canyon impractical for river navigation, interest grew in connecting the area by rail. By 1884, the Oregon Railroad & Navigation Company (later integrated into Union Pacific ) had connected Portland, Oregon , to the Union Pacific line at Granger, Wyoming , via Huntington and Pocatello . Boise, initially bypassed due to

9612-665: The Bureau (Office) of Indian Affairs. Under federal law, the government patented reservations to tribes, which became legal entities that at later times have operated in a corporate manner. Tribal tenure identifies jurisdiction over land-use planning and zoning, negotiating (with the close participation of the Bureau of Indian Affairs) leases for timber harvesting and mining. Tribes generally have authority over other forms of economic development such as ranching, agriculture, tourism, and casinos. Tribes hire both members, other Indians and non-Indians in varying capacities; they may run tribal stores, gas stations, and develop museums (e.g., there

Perrine , who homesteaded near Shoshone Falls in the 1880s, went on to develop one of the most successful Carey Act projects. In 1900 Perrine filed a claim for water from the Snake River, and backed by significant private capital, oversaw the construction of Milner Dam and a canal system to irrigate some 250,000 acres (100,000 ha) of

By 8.5 Ma the Salmon-Clearwater was established in the Columbia River's modern path through Wallula Gap , although the Columbia itself still flowed somewhere to the west. The last of the Columbia basalt flows occurred around 6 Ma; by then,

10146-465: The Dawes Act. However, the vast fragmentation of reservations occurred from the enactment of this act up to 1934, when the Indian Reorganization Act was passed. However, Congress authorized some allotment programs in the ensuing years, such as on the Palm Springs/Agua Caliente Indian Reservation in California. Allotment set in motion a number of circumstances: The demographic factor, coupled with landownership data, led, for example, to litigation between

10324-464: The Department of Interior made offers to 536 landowners with fractional interests at Fort Hall Reservation for buy-back of lands valued at $ 11 million. In total by July 2016, the Department of Interior had put about 1.5 million acres of land into trust for tribes under this program. Relations with the city of Pocatello became strained in April 2016 after the tribes learned that the city had contracted with Pocatello Solar, based in Boise, to lease

10502-489: The Devils Lake Sioux and the State of North Dakota, where non-Indians owned more acreage than tribal members even though more Native Americans resided on the reservation than non-Indians. The court decision turned, in part, on the perception of Indian character , contending that the tribe did not have jurisdiction over the alienated allotments. In a number of instances—e.g., the Yakama Indian Reservation—tribes have identified open and closed areas within reservations. One finds

10680-523: The Europeans encountered the New World, the American colonial government determined a precedent of establishing the land sovereignty of North America through treaties between countries. This precedent was upheld by the United States government. As a result, most Native American land was purchased by the United States government, a portion of which was designated to remain under Native sovereignty. The United States government and Native Peoples do not always agree on how land should be governed, which has resulted in

10858-500: The Fort Hall Reservation, leading to the Bannock War . The US army defeated the Bannock and their Paiute allies and proceeded to restrict travel in and out of the reservation. While Lewiston was now well connected by river, travel to Boise and other points upstream on the Snake River remained difficult due to the formidable obstacle of Hells Canyon. In 1865, Thomas Stump attempted to pilot the Colonel Wright up Hells Canyon, making it 80 miles (130 km) upriver before hitting rocks in

The private contracts that once characterized the sale of Indian land to various individuals and groups—from farmers to towns—were replaced by treaties between sovereigns. This protocol was adopted by the United States Government after the American Revolution. On March 11, 1824, U.S. Vice President John C. Calhoun founded

11570-465: The Indians. The U.S. Army forced the Shoshone back onto the reservation. From 1868 to 1932, the federal government reduced the territory of the reservation by two-thirds, taking some for such projects as railroads and roads, and allowing non-Native settlers to encroach on the grounds. Most importantly, under the Dawes Act of 1887, the government attempted to impose the model of private property and subsistence farming, thinking to encourage assimilation of

11748-409: The Lewis and Clark expedition would later follow in order to reach the Snake and Columbia Rivers. The river's modern name comes from a misunderstanding of the Shoshone Tribal Sign in PISL . The Plains Indians referred to the Shoshone people as "Snake People", while the Shoshone are believed to have referred to themselves as "People of the River of Many Fish". However, the Shoshone sign for "salmon"

The river's rapids posed a major navigation hazard, and from November to April the river was generally too low for ships. Despite these challenges, the water transport of freight and passengers was greatly profitable. Up river, the Shoshone and other tribes were also becoming increasingly wary of settlers; in 1854

This act came too, because "the federal government began to compress Indigenous lands because it needed to send troops to Texas during the Mexican-American War and protect American immigration traveling to Oregon and California." The Federal Government of America had their own needs and desires for Indigenous Land Reservations. He says, "the reconnaissance of explorers and other American officials understood that Indigenous Country possessed good land, bountiful game, and potential mineral resources." The American Government claimed Indigenous land for their own benefits with these creations of Indigenous Land Reservations . States such as Texas had their own policy when it came to Indian Reservations in America before 1850. Scholarly author George D. Harmon discusses Texas' own reservation system which "Prior to 1845, Texas had inaugurated and pursued her own Indian Policy of

Here the trail diverged, with the northern route fording the river to reach the HBC trading post at Fort Boise while the southern route continued into what is now the eastern Oregon desert. While the northern route passed through more favorable country,

12994-740: The Oregon–Idaho border. It is joined by several major tributaries in quick succession – the Boise River from the right, the Owyhee and Malheur Rivers from the left, the Payette and Weiser Rivers from the right near Ontario, Oregon , then the Powder and Burnt Rivers from the left. Continuing north, the river enters Hells Canyon , which slices between the Rocky Mountains of Idaho and

13172-665: The Salmon River at what is now Salmon, Idaho , naming the stream "Lewis's River". Thwarted by the river's rapids, they were forced to cross the Bitterroot Mountains via the Nez Perce trail at Lolo Pass. After paddling down the Kooskooskee (Clearwater River), they reached the junction with the Snake and camped there with the Nez Perces on October 10, 1805. They correctly surmised that the river coming from

13350-472: The Shoshone-Bannock tribes annually with goods and supplies annuities worth 5,000 dollars. The U.S. government often failed to provide the annuity goods on time, and food supplies sometimes arrived spoiled. In addition, the lands of the reservation, located on the Snake River Plain, were not appropriate for the subsistence-type agriculture that the government wanted the Shoshone-Bannock to adopt. In

13528-605: The Snake River Plain and the Palouse, though the majority of the Snake River Plain is Bureau of Land Management land. The Snake River watershed borders several other major North American watersheds. To the south it borders the endorheic Great Basin , including the area draining to Utah's Great Salt Lake . To the east it borders the watersheds of the Green River (part of the Colorado River system which drains to

13706-472: The Snake River Plain between 600 and 1500 CE. By the time of first European contact, the Snake River watershed was populated by several Native American tribes. The territory of the Nez Perce (Nimiipuu) stretched across what is now north-central Idaho, southeast Washington and northeast Oregon, including much of the lower Snake River below Hells Canyon, most of the Clearwater and Grande Ronde River, and

13884-604: The Snake River Plain formed as the North American Plate moved westward over the Yellowstone hotspot. Upwelling magma caused the continental crust to rise, forming highlands in a similar fashion to the modern Yellowstone plateau and leaving behind enormous basalt flows in its wake. As the hotspot migrated east relative to the North American Plate, the land behind it collapsed and sank, creating

14062-451: The Snake River Plain. Completed in 1905, the project was an immediate success. The rapid transformation of the barren landscape into productive farmland led to the moniker " Magic Valley ", and led to massive growth of the city of Twin Falls. During certain times of the year, almost all the Snake River's flow was diverted at Milner Dam, and since then, Shoshone Falls has regularly run dry in

14240-566: The Snake River at Ice Harbor Dam since 1962. The mean annual discharge for the 61-year period between 1962 and 2023 was 49,580 cubic feet per second (1,404 m /s), with a maximum recorded daily mean of 305,000 cu ft/s (8,600 m /s) on June 19, 1974, and a minimum daily mean of 2,000 cu ft/s (57 m /s) on November 29, 1961. A historic June 1894 flood at the Ice Harbor site reached an estimated peak of 409,000 cu ft/s (11,600 m /s). In terms of discharge,

14418-526: The Snake River drain more than 100 square miles (260 km ). Of these, the twelve listed below drain an area greater than 2,000 square miles (5,200 km ). The present-day course of the Snake River was pieced together over millions of years from several formerly disconnected drainage systems. Much of what would become the Pacific Northwest lay under shallow seas until it was uplifted starting about 60 million years ago (Ma). The outlet of

14596-483: The Snake River is the twelfth largest river in the United States, and it contributes about one-fifth of the Columbia's total outflow into the Pacific. The volume of the Snake River peaks in late spring and early summer as snow melts in the Rocky Mountains, and reaches its lowest point in the fall. Despite the numerous dams regulating its flow, its discharge into the Columbia remains highly seasonal. At Ice Harbor Dam,

14774-472: The Snake River posed a formidable barrier; during high water, many travelers were forced to take the hot, dry southern route, or risk drowning. Travelers going via Fort Boise had to cross the river one more time to rejoin the trail heading west. A ferry existed at Fort Boise since at least 1843; the Three Island crossing was also replaced by a ferry in 1869. A new wave of travelers came in the 1860s with

14952-477: The Snake River took several thousand salmon in one afternoon by means of spears." To the east and upriver of the falls, many Shoshone and Bannock lived in more nomadic groups, traveling to the falls during the spring salmon run then gathering camas bulbs and hunting bison through the summer and autumn months. The Snake River at Hells Canyon formed a natural dividing line between the Nez Perce and Shoshone, who considered each other enemies. The Nez Perce allied with

15130-713: The Snake River watershed derives from snowmelt. Jackson Hole, Wyoming experiences an alpine climate with an average of 30 in (760 mm) of rain and 252 in (6,400 mm) of snow. The coldest month is January, with a mean temperature of 13 °F (−11 °C), and the hottest is July at 57.7 °F (14.3 °C). Twin Falls experiences a semi-arid climate , with about 9 in (230 mm) of rain and 13 in (330 mm) of snow. Monthly mean temperatures range from 29.4 °F (−1.4 °C) in January to 73.1 °F (22.8 °C) in July. The Columbia Basin around

15308-508: The Snake River. South-central Idaho earned the nickname " Magic Valley " with the rapid transformation of desert into farmland. Numerous hydroelectric dams were also constructed, and four navigation dams on its lower section created a shipping channel to Lewiston, Idaho – the furthest inland seaport on the West Coast. While dam construction, commercial fishing and other human activities have greatly reduced anadromous fish populations since

15486-551: The Snake empties into the Columbia River at Burbank, Washington , southeast of the Tri-Cities . The confluence is located on Lake Wallula , the impoundment behind McNary Dam on the Columbia, 341 feet (104 m) above sea level. From there, the Columbia River flows another 325 miles (523 km) west to empty into the Pacific Ocean. The U.S. Army Corps of Engineers has measured the discharge , or flow rate, of

15664-551: The Snake headwaters was sculpted by multiple Ice Age glaciations. Starting about 200,000 years ago, the Buffalo glaciation filled Jackson Hole to a depth of 2,000 feet (610 m). Ice flowed down the Snake River Canyon all the way to Idaho. The Bull Lake glaciation, about 80,000–35,000 years ago, and the Pinedale glaciation, ending about 15,000 years ago, were much smaller and did not fill the entire valley. These glaciations carved

15842-656: The Snake, Clearwater and Salmon Rivers. Clans gathered at communal fishing sites starting about May or June. Fishing moved from the lower rivers to higher elevation streams throughout the summer, while fall-run fish were preserved for winter use. Shoshones in the western part of the Snake River Plain also depended heavily on the salmon run. At Shoshone Falls and the smaller cataracts downstream, fishing platforms, temporary brush weirs, spears, baskets and fish traps were employed at large scale. Captain Benjamin Bonneville in 1832 observed that "Indians at Salmon Falls on

16020-453: The Snake. The Lower Snake River Project consists of four dams equipped with navigation locks – Lower Granite , Little Goose , Lower Monumental and Ice Harbor – which have transformed the once fast-flowing lower Snake River into a series of lakes, enabling heavy barges to travel between the Columbia River and the Port of Lewiston. About 10 miles (16 km) downstream from Ice Harbor Dam,

16198-544: The Tetons, and a graben valley developed between the Hoback and Teton fault zones, creating Jackson Hole. As the valley dropped, water filled it to create Lake Teewinot, which drained east into the Green River – Colorado River system. About 1 Ma, the Snake River captured the Jackson Hole watershed, draining Lake Teewinot and finally connecting the modern-day Snake headwaters to the rest of the river. This landscape around

16376-778: The U.S." Texas was one of the States before 1850 that chose to create their own reservation system as seen in Harmon's article, "The United States Indian Policy in Texas, 1845–1860." The State of "Texas had given only a few hundred acres of land in 1840, for the purpose of colonization". However, "In March 1847, … [a] special agent [was sent] to Texas to manage the Indian affairs in the State until Congress should take some definite and final action." The United States of America allowed its states to make up their own treaties such as this one in Texas for

16554-564: The United States. By 1877, President Rutherford B. Hayes began phasing out the policy, and by 1882 all religious organizations had relinquished their authority to the federal Indian agency. In 1887, Congress undertook a significant change in reservation policy by the passage of the Dawes Act , or General Allotment (Severalty) Act. The act ended the general policy of granting land parcels to tribes as-a-whole by granting small parcels of land to individual tribe members. In some cases, for example,

16732-509: The ancestral Columbia River to the Pacific was established about 40 Ma. By about 17 Ma, the "Salmon-Clearwater River", or the modern day lower Snake River, flowed west into the Columbia and on to the Pacific. Another ancient river system drained what is now the western Snake River Plain. Some geologists propose that this flowed to the Columbia on a course south of the present-day Blue Mountains, while others propose it drained towards Northern California . The Columbia River basalts ,

16910-401: The aquifer to reach the Snake River, as does excess irrigation water absorbed into the ground. The major spring complexes at American Falls and Thousand Springs (near Hagerman, Idaho ) keep the river flowing steadily even in the driest of summers. At King Hill , about 50 miles (80 km) northwest of Twin Falls, water levels remain about 10,000 cu ft/s (280 m /s) for most of

17088-417: The basalt layers to form a plateau. From about 11–9 Ma, crustal deformation related to the Yellowstone hotspot caused the western half of the Snake River Plain to sink, creating a graben -type valley between parallel fault zones to the northeast and southwest. The outlet of the ancient Snake River was blocked, and water accumulated to form the vast Lake Idaho starting about 10 Ma. The eastern half of

17266-464: The basis for hotel and conference facilities, to draw visitors and revenue to reservations. Successful gaming operations on some reservations have greatly increased the economic wealth of some tribes, enabling their investment to improve infrastructure, education, and health for their people. Serious crime on Indian reservations has historically been required (by the 1885 Major Crimes Act , 18 U.S.C. §§1153, 3242, and court decisions) to be investigated by

17444-458: The confluence with the Malad River near Hagerman Fossil Beds National Monument , the Snake River descends a total of 1,300 feet (400 m) over a series of cataracts and rapids, chief of which include Caldron Linn , Twin , Shoshone , Pillar , Auger, and Salmon Falls . Idaho Power operates several small hydroelectric plants along this stretch of the river. The largest single drop

17622-605: The creation of the Reclamation Service (now the Bureau of Reclamation ) in 1902, the federal government began to play a more direct role in water resources development. The expansive Minidoka Project was the first federal reclamation project in Idaho. Starting with Minidoka Dam in 1906, the project would grow over the next few decades to include major reservoirs at Jackson Lake , American Falls and Island Park , and

17800-441: The distinctive peaks of the Tetons into their present form and scoured lake basins in the valley floor, including modern-day Jackson Lake. While the Snake River course beyond Jackson Hole was not directly impacted by glaciations, its landscape was dramatically changed by Ice Age flooding events. About 30,000 years ago, the climate of western North America was much wetter than today. The Great Salt Lake Basin filled with water to form

17978-556: The doubtful question is set at rest forever. Yet from the force of the current and the frequency of rapids, it may still be advisable, and perhaps preferable, to continue the land transport." Canadian fur trappers with the British Hudson's Bay Company (HBC) reached the Snake River watershed in 1819. As American fur trappers kept coming to the region, the HBC ordered the Canadians to kill as many beavers as they could, under

18156-505: The easily farmable land was soon developed, and they could not raise the capital for further expansion. In addition, low water by late summer posed a challenge to farmers, and the irrigation companies could not afford to build dams to provide water storage. With many private irrigation companies verging on insolvency, the federal government began to explore programs assisting agricultural development. The 1894 Carey Act granted large tracts of dry federal land to western states, which then sold

18334-603: The east is the 60-mile-long (97 km) Portneuf Range; both Mount Putnam and South Putnam Mountain are located on the Fort Hall Reservation. Founded under an 1868 treaty, the reservation is named for Fort Hall , a trading post in the Portneuf Valley that was established by European Americans. It was an important stop along the Oregon and California Trails in the middle 19th century. A monument on

18512-471: The end of large new irrigation developments not only for the Snake River system, but for the Bureau of Reclamation as a whole. Agriculture has significantly impacted water quality in the Snake River upstream of Hells Canyon. Water removed from the river for irrigation becomes contaminated with chemical fertilizers and manure, and percolates into the Snake River Aquifer. Pollutants collect in

18690-633: The enterprises, and more than 300 in gaming. Since the late 20th century, the Tribes have developed the Fort Hall Casino and two smaller satellite casinos on the reservation. They are all operated by the Shoshone-Bannock Tribes, who use the revenues for additional economic development and to support education and healthcare for the people. The combined payroll of the various activities is more than $ 32 million. The tribal government

18868-517: The entire Columbia River watershed. Compared with the Columbia above their confluence, the Snake River is about 180 miles (290 km) longer and drains a similarly sized area, though the Columbia carries more than twice the volume of water. The Snake River watershed is very mountainous, with the northern two-thirds of it occupied by vast mountain ranges of the Rockies, primarily the Salmon River Mountains of central Idaho and

19046-543: The federal Native American agencies and generally poor conditions among the relocated tribes. Many tribes ignored the relocation orders at first and were forced onto their limited land parcels. Enforcement of the policy required the United States Army to restrict the movements of various tribes. The pursuit of tribes in order to force them back onto reservations led to a number of wars with Native Americans which included some massacres. The most well-known conflict

19224-454: The federal government began to forcibly relocate nations to parcels of land to which they often had no historical or cultural connection. Compared to other population centers in the U.S., reservations are disproportionately located on or near toxic sites hazardous to the health of those living or working in close proximity, including nuclear testing grounds and contaminated mines. The majority of American Indians and Alaska Natives live outside

19402-756: The federal government, usually the Federal Bureau of Investigation , and prosecuted by United States Attorneys of the United States federal judicial district in which the reservation lies. Tribal courts were limited to sentences of one year or less, until on July 29, 2010, the Tribal Law and Order Act was enacted which in some measure reforms the system permitting tribal courts to impose sentences of up to three years provided proceedings are recorded and additional rights are extended to defendants. The Justice Department on January 11, 2010, initiated

19580-442: The first American fur trading post west of the Rocky Mountains, but abandoned it after that year's harsh winter. The 1811 Pacific Fur Company expedition led by Wilson Price Hunt attempted to find a route from Henrys Fork to the Columbia River. After suffering a wreck in the falls of the Snake River Canyon, they took an overland route through the Snake River Plain, through what is now the Boise Valley or Treasure Valley, then crossed

19758-479: The first successful river descent of Hells Canyon, a harrowing ride that skirted disaster several times. In 1895 the steamboat Norma , which had been built to haul copper ore on the Snake River above Hells Canyon, also made the run under similar circumstances. In the 1870s, Boise (to which Idaho's capital was moved in 1866) expanded rapidly as growth slowed in Lewiston. Gold drew more than 25,000 prospectors to

19936-411: The forms of government found outside the reservation. With the establishment of reservations, tribal territories diminished to a fraction of their original areas; customary Native American practices of land tenure were sustained only for a time, and not in every instance. Instead, the federal government established regulations that subordinated tribes to the authority, first, of the military, and then of

20114-405: The four lower Snake River dams for fish passage is a significant ongoing policy debate in the Pacific Northwest. The Snake River begins on Two Oceans Plateau near the southern border of Yellowstone National Park , about 9,200 feet (2,800 m) above sea level in the Rocky Mountains of Wyoming . From there, it flows west then south into Grand Teton National Park , where it feeds Jackson Lake ,

20292-522: The geographic depression of the eastern Snake River Plain. The gradual eastward migration of this topographic high had the effect of pushing the Continental Divide to the east. Prior to the formation of the eastern Snake River Plain, the drainage area east of about Arco, Idaho – the modern headwaters and upper course of the Snake River – flowed towards the Atlantic Ocean via the Mississippi River system. The migrating Continental Divide tilted

20470-498: The government's settlement of the Cobell v. Salazar class action suit over mismanagement of fee/lease accounts. Under this program, the government is buying back fractional interests in lands within reservations to put the land into trust for the communal use of the tribes. It is an effort to restore some of the lands lost following the 19th century allotment process and reduce fractional holdings too small to use readily. In July 2016,

20648-457: The groundwater and eventually enter the river via spring flows. Excess nitrogen, phosphorus and bacterial loads occur in many locations across southern Idaho. Large algae blooms are a recurring issue in summer. The U.S. Environmental Protection Agency has established water quality guidelines for Snake River flows entering Hells Canyon, which cover bacteria, mercury, excess nutrients, pesticides, sediments and water temperature. Implementation of

20826-527: The habitat of game they depended on. In January 1863 Colonel Patrick Edward Connor led his troops from Fort Douglas to chastise the Shoshone. In what is known as the Bear River massacre (1863), his US Army forces killed more than 400 Shoshone, including women and children, in present-day southeastern Idaho. Warned of Connor's advance, Pocatello had led his people out of harm's way. Another chief and his band were attacked and largely destroyed. Seeing

21004-577: The hemp weed". Another Nez Perce name for the Snake River was Pikúunen , specifically referring to the stretch upstream of the Clearwater confluence. The Wanapum and Walla Walla people called the lower Snake River below the Clearwater Naxíyam Wána . The Shoshone called the river Yampapah , after the yampah plant that grew profusely along its banks. Downriver of Shoshone Falls, salmon and their cousins such as steelhead trout – anadromous fish which spend their adult lives in

21182-553: The idea before it was fully implemented, five tribes were terminated—the Coushatta , Ute , Paiute , Menominee and Klamath —and 114 groups in California lost their federal recognition as tribes. Many individuals were also relocated to cities, but one-third returned to their tribal reservations in the decades that followed. Federally recognized Native American tribes possess limited tribal sovereignty and are able to exercise

21360-587: The indigenous tribe sell their land to build a lighthouse. A treaty signed by John Forsyth, the Secretary of State on behalf of Van Buren, also dictates where indigenous peoples must live in terms of the reservation system in America between the Oneida People in 1838. This treaty allows the indigenous peoples five years on a specific reserve "the west shores of Saganaw bay". The creation of reservations for indigenous people of America could be as little as

21538-562: The lack of data on crime rates and law enforcement response. As of 2012, a high incidence of rape continued to impact Native American women. A survey of death certificates over a four-year period showed that deaths among Indians due to alcohol are about four times as common as in the general U.S. population and are often due to traffic collisions and liver disease with homicide , suicide , and falls also contributing. Deaths due to alcohol among American Indians are more common in men and among Northern Plains Indians. Alaska Natives showed

21716-525: The land reserves in a better state for the benefit of society" with approval of Indigenous reservations before 1850. The letter is signed by Isaac Shelby and Jackson. It discusses several regulations regarding the Native Americans and the approval of Indigenous segregation and the reservation system. President Martin Van Buren negotiated a treaty with the Saginaw Chippewas in 1837 to build

21894-459: The land to farmers and solicited private investors to organize irrigation districts. Investors would then recoup their capital by selling water rights to farmers. Irrigation plans were reviewed by engineers, who determined the economic feasibility of the projects. Although the Carey Act saw little success in most states, it greatly benefited Idaho. Some 60 percent of all lands developed under

22072-457: The landscape of the Snake River Plain, creating the Snake River Canyon and its waterfalls, vast boulder fields, cliffs and coulees . The floodwaters then emptied through Hells Canyon; however, most evidence of their effects on the lower Snake River was erased by the much larger Missoula Floods that engulfed the Columbia Basin during the same period. Caused by the repeated collapse of an ice dam in western Montana, dozens of floods overflowed into

22250-495: The late 1840s and 1850s, when emigrant wagon trains increasingly crossed their territory which put strain on food and water resources, disrupting the way of life for the Shoshone and Bannock. In the 1850s the Shoshone, led by Chief Pocatello , attacked emigrant parties in an effort to drive them off, as the settlers encroached on their hunting grounds and game. After initial hostilities, the Mormons , led by Brigham Young , pursued

22428-534: The late 19th century, the Snake River watershed is still considered important habitat for these fish. The Snake and its tributary, the Salmon River , host the longest sockeye salmon run in the world, stretching 900 miles (1,400 km) from the Pacific to Redfish Lake , Idaho. Since the 1950s, public agencies, tribal governments and private utilities have invested heavily in fishery restoration and hatchery programs, with limited success. The proposed removal of

22606-550: The latter includes Gannett Peak , the highest point in the Snake River basin at 13,816 feet (4,211 m). Surface volcanic features – such as lava fields, cones , and thermal springs – are replete in the southern part of the Snake watershed, from Craters of the Moon National Monument northeast of Twin Falls to the Yellowstone caldera, while ancient lava flows of the Columbia River basalts underlie

22784-710: The least incidence of death. Under federal law, alcohol sales are prohibited on Indian reservations unless the tribal councils allow it. Gang violence has become a major social problem. A December 13, 2009, article in The New York Times about growing gang violence on the Pine Ridge Indian Reservation estimated that there were 39 gangs with 5,000 members on that reservation alone. As opposed to traditional "Most Wanted" lists, Native Americans are often placed on regional Crime Stoppers lists offering rewards for their whereabouts. When

22962-526: The lower Salmon River. The Northern Shoshone and the Bannock , a Northern Paiute group that became culturally associated with the Shoshone, occupied an area stretching from the Snake River Plain east to the Rocky Mountains and south towards the Great Basin, as well as valleys of the upper Salmon River. A Nez Perce name for the river was Kimooenim or variations thereof, meaning "the stream/place of

23140-481: The lower Snake River from the north, backing water as far upstream as Lewiston. The formerly west-flowing Palouse River was rerouted to flow south into the Snake River, forming Palouse Falls, whose outsized plunge pool attests to the force of the floods. Starting around the end of the last glacial period, the Snake River Plain was inhabited by hunter-gatherers of the ancient Clovis (10000–9000 BCE), Folsom (9000–8000 BCE) and Plano (8600–5800 BCE) cultures. Along

23318-617: The lower Snake River in Washington, the Marmes Rockshelter – flooded in 1968 after the construction of Lower Monumental Dam – has yielded archeological evidence of continuous human occupation from about 9000 BCE until about 1300 CE. Starting about 2200 BCE, people in the western Snake River basin began to adopt a semi-sedentary lifestyle, with an increased reliance on fish (primarily salmon) and food preservation and storage. Shoshoni -speaking peoples arrived in

23496-487: The majority of non-Indian landownership and residence in the open areas and, contrariwise, closed areas represent exclusive tribal residence and related conditions. Indian country today consists of tripartite government—i. e., federal, state and/or local, and tribal. Where state and local governments may exert some, but limited, law-and-order authority, tribal sovereignty is diminished. This situation prevails in connection with Indian gaming, because federal legislation makes

23674-430: The massive Lake Bonneville , about the size of modern-day Lake Michigan . About 15,000 years ago the lip of Red Rock Pass south of present-day Pocatello, Idaho abruptly collapsed, releasing a tremendous volume of water from Lake Bonneville into the Snake River Plain. The peak of the flood was about 500 times bigger than the largest recorded flood of the Snake at Idaho Falls in modern times. The flood completely altered

23852-565: The mean monthly discharge is highest in May and June at over 100,000 cu ft/s (2,800 m /s), and lowest in September and October at less than 25,000 cu ft/s (710 m /s). Mean annual discharge also fluctuates significantly, from a record high of 86,240 cu ft/s (2,442 m /s) in 1965, to a low of 27,890 cu ft/s (790 m /s) in 1997. In southern Idaho, Snake River flows are significantly influenced by

24030-470: The mining industry and the difficulty of importing goods set off an agricultural boom in the Boise Valley. By the 1880s, settlers also came to the upper Snake River north of Idaho Falls, where fertile, sandy soils presented ideal conditions for the iconic russet potato ("Idaho potato"). The dry climate made irrigation necessary, and numerous private irrigation companies were formed. Private canal systems around Boise and Idaho Falls saw some success, but all

24208-450: The ocean, returning to fresh water to spawn – were a key food source for indigenous peoples, and were of great cultural importance. Rituals such as the first salmon ceremony were widely observed along the Columbia, Snake and other Northwest rivers, and so were strict catch limits, such that a healthy number of salmon would survive to reach their natal streams. The Nez Perce had more than seventy permanent villages among their fishing grounds on

24386-460: The old country. It is its lonely grandeur that impresses one so deeply; all of the other historic places have the adjuncts of civilization, and one is almost overshadowed by a city while in their presence." Most travelers on the Oregon Trail regarded the arid Snake River Plain as an obstacle to be crossed, not a land to be settled. This began to change with the Boise gold strikes, where the demands of

24564-518: The original site in 1863. A military detachment was stationed there to quell any further violence; however, tensions continued to increase, and more wagon trains and mining parties were attacked. Starting in 1864, the Snake War was fought across much of southern Idaho, with numerous battles between the U.S. Army and the Shoshone, Bannock and Paiute. By 1868, exhausted after years of fighting, Chief Pocatello and many others surrendered and relocated to

24742-536: The outflow carved Hells Canyon, emptying Lake Idaho and integrating the upper Snake and Salmon-Clearwater into a single river system. The Teton Range, a defining topographic feature of the modern Snake River headwaters, first began to rise about 10 Ma as the Teton Fault began to move, displacing the mountain block upward as the surrounding land dropped. About 2 Ma, the Hoback Fault formed east of

24920-476: The pollution will be hazardous for a very long time. As a result of this case, EPA has worked with the Tribes to develop the Clean Air Act ’s Tribal Authority Rule , to provide tribes with more control over enforcement of clean air quality. The company abandoned the plant and related mine, due in large part to increased costs of electricity and competition from cheaper Chinese phosphate. Seventeen mines in

25098-660: The power of US forces, Pocatello subsequently sued for peace and agreed to relocate his people in 1868 to a newly established reservation along the Snake River . Four bands of Shoshone and the Bannock band of the Northern Paiute relocated to the reservation, then consisting of 1.8 million acres (7,300 km) of land. As part of the Fort Bridger Treaty of 1868 , the U.S. government agreed to supply

25276-468: The present-day confluence of the Columbia River and Salmon-Clearwater had been established, with the combined flow draining through Wallula Gap. About 2.5 Ma, Lake Idaho reached a maximum elevation of 3,600 feet (1,100 m) above modern sea level, and overflowed northward into the Salmon-Clearwater drainage near present-day Huntington, Oregon . Over a period of about two million years,

25454-554: The property for $ 1 to nearby Pocatello , a city about 9 miles (14 km) to the east, which developed it as a regional airport . In the 21st century, there continue to be conflicts over development at the airport without consultation with the tribe. (See material below). FMC Corporation operated a phosphate mine and plant under a lease at the Fort Hall Reservation. Between 1949 and 2001, it produced an estimated 250 million pounds of elemental phosphorus annually. It has had serious adverse environmental effects. In 1989, as part of what

25632-557: The purpose of colonization. The passage of the Indian Removal Act of 1830 marked the systematization of a U.S. federal government policy of moving Native populations away from European-populated areas, whether forcibly or voluntarily. One example was the Five Civilized Tribes , who were removed from their historical homelands in the Southeastern United States and moved to Indian Territory , in

25810-581: The rationale that "if there are no beavers, there will be no reason for the Yanks to come," and even if the Americans did ultimately gain control, the HBC would already have taken all the profit. Focused primarily on the upper Snake River region, the "fur desert" policy was carried out in nine expeditions from about 1824–1831 and aimed to decrease the Americans' economic interest in the Oregon Country ,

25988-458: The region have been designated as Superfund sites because of selenium poisoning. Since 2001, FMC has been working on cleanup at the reservation. The tribe has developed its own expertise in air, water and land quality, but its resources are still seriously threatened by the extensive cleanup needed. The Shoshone-Bannock Tribes chose to participate in the Department of Interior's Native Nations Land Buy-Back Program, established after 2009 as part of

26166-535: The regional slope such that drainage flowed west into Lake Idaho, whose water levels saw a significant increase about 4.5 Ma. The Snake River Plain drainage system continued to expand east, towards what is now Yellowstone National Park. During this expansion, the Snake also captured the Bear River , which was only rerouted towards its modern outlet in the Great Salt Lake Basin about 50,000 or 60,000 years ago by lava flows in southeast Idaho. In

26344-601: The reservation (e.g., Enabling Act of 1910 at Section 20 ). As a general practice, such land may sit idle or be used for cattle grazing by tribal ranchers. In 1979, the Seminole tribe in Florida opened a high-stakes bingo operation on its reservation in Florida. The state attempted to close the operation down but was stopped in the courts. In the 1980s, the case of California v. Cabazon Band of Mission Indians established

26522-417: The reservation marks the former site of the fort. Interstate 15 serves the community of Fort Hall , the largest population center on the reservation. The total population of the reservation was 5,762 at the 2000 census . The Shoshone-Bannock Tribes has more than 5,300 enrolled members, and more than half reside on the Fort Hall Reservation. Others have moved to urban areas for work. The tribes are governed by

26700-434: The reservations, mainly in the larger western cities such as Phoenix and Los Angeles . In 2012, there were more than 2.5 million Native Americans , with 1 million living on reservations. From the beginning of the European colonization of the Americas , Europeans often removed Indigenous peoples from their homelands. The means varied, including treaties made under considerable duress, forceful ejection, violence, and in

26878-586: The reservations. Likewise, over two million acres (8,000 km ) of land were returned to various tribes. Within a decade of Collier's retirement the government's position began to swing in the opposite direction. The new Indian Commissioners Myers and Emmons introduced the idea of the "withdrawal program" or " termination ", which sought to end the government's responsibility and involvement with Indians and to force their assimilation. The Indians would lose their lands but were to be compensated, although many were not. Even though discontent and social rejection killed

27056-424: The right of reservations to operate other forms of gambling operations. In 1988, Congress passed the Indian Gaming Regulatory Act , which recognized the right of Native American tribes to establish gambling and gaming facilities on their reservations as long as the states in which they are located have some form of legalized gambling. Today, many Native American casinos are used as tourist attractions, including as

27234-524: The right of self-governance, including but not limited to the ability to pass laws, regulate power and energy, create treaties, and hold tribal court hearings. Laws on tribal lands may vary from those of the surrounding area. The laws passed can, for example, permit legal casinos on reservations. The tribal council, not the local government or the United States federal government , often has jurisdiction over reservations. Different reservations have different systems of government, which may or may not replicate

27412-425: The river's mouth also has a semi-arid climate, with about 10 in (250 mm) of rain and 5 in (130 mm) of snow as measured at Ice Harbor Dam. January is the coldest month with a mean temperature of 34.3 °F (1.3 °C), and July is the hottest month at 74.6 °F (23.7 °C). Semi-arid shrubland and rangeland covers about 50 percent of the Snake River watershed. Natural vegetation

27590-473: The river, Hells Canyon is one of the deepest canyons in North America, almost one-third deeper than the Grand Canyon . Within the canyon it is joined from the left by the Imnaha River , then from the right by its longest tributary, the Salmon River . Further north, it begins to form the Idaho– Washington border, and receives the Grande Ronde River from the left. From the end of Hells Canyon at Asotin, Washington , it flows north to Lewiston, Idaho , where it

27768-484: The settlers encroached on territory and natural resources in the West. In 1868, President Ulysses S. Grant pursued a "Peace Policy" as an attempt to avoid violence. The policy included a reorganization of the Indian Service, with the goal of relocating various tribes from their ancestral homes to parcels of lands established specifically for their inhabitation. The policy called for the replacement of government officials by religious men, nominated by churches, to oversee

27946-439: The south was a continuation of "Lewis's" or Salmon River. The expedition journals note the Nez Perce called it Kimooenim , although William Clark later erased mentions of the name to replace with "Lewis's". Six days later they reached the confluence of the Snake and Columbia Rivers, after noting a number of dangerous rapids as well as many native fishing sites on the lower Snake. The expedition established friendly relations with

28124-548: The state a party to any contractual or statutory agreement. Finally, occupancy on reservations can be by virtue of tribal or individual tenure. There are many churches on reservations; most would occupy tribal land by consent of the federal government or the tribe. Bureau of Indian Affairs (BIA) agency offices, hospitals, schools, and other facilities usually occupy residual federal parcels within reservations. Many reservations include one or more sections (about 640 acres) of land for schools, but such land typically remains part of

28302-405: The state of West Virginia . Reservations are unevenly distributed throughout the country, the majority being situated west of the Mississippi River and occupying lands that were first reserved by treaty ( Indian Land Grants ) from the public domain. Because recognized Native American nations possess tribal sovereignty , albeit of a limited degree, laws within tribal lands may vary from those of

28480-433: The summer. The Idaho State Historical Society writes that "Perrine’s venture contrasted remarkably with private canal company failures that led to congressional provision for federal reclamation projects after 1902. As a rare successful example of state supervised private irrigation development provided for in [the Carey Act] of 1894, Milner Dam and its canal system have national significance in agricultural history." With

28658-415: The surrounding and adjacent states. For example, these laws can permit casinos on reservations located within states which do not allow gambling, thus attracting tourism. The tribal council generally has jurisdiction over the reservation, not the U.S. state it is located in, but is subject to federal law. Court jurisdiction in Indian country is shared between tribes and the federal government, depending on

28836-417: The tribal affiliation of the parties involved and the specific crime or civil matter. Different reservations have different systems of government, which may or may not replicate the forms of government found outside the reservation. Most Native American reservations were established by the federal government but a small number, mainly in the East, owe their origin to state recognition . The term "reservation"

29014-411: The tribe has the authority to modify tenant-in-common practices. With the General Allotment Act (Dawes) , 1887, the government sought to individualize tribal lands by authorizing allotments held in individual tenure. Generally, the allocation process led to grouping family holdings and, in some cases, this sustained pre-reservation clan or other patterns. There had been a few allotment programs ahead of

29192-437: The tribes later sold their plots because they were too small to be successfully farmed, leading to the tribes' losing control of more lands. In 1934 during the Franklin D. Roosevelt administration, the US Congress passed the Indian Reorganization Act , created in part to end the allotment process and encourage tribes to re-establish self-government and to stabilize their land bases. In 1936 these two tribes reorganized, wrote

29370-405: The tribes to the majority type farm. It registered all members of the tribes and allotted individual 160-acre plots of land to each household. Given the arid local conditions, these allotments were generally too small to support subsistence agriculture. The government declared the remainder of the formerly communal land to be "surplus" and sold much of it to European-American settlers. Some members of

29548-434: The vast region of the Pacific Northwest centering on modern-day British Columbia, Washington, Oregon and Idaho. By the time the Americans annexed Oregon Territory in 1848, beaver were nearly extirpated across much of the Rocky Mountains. Starting in the 1840s, the Oregon Trail became well established, and thousands of settlers passed through the Snake River Plain on their way to the Willamette Valley . Coming from Wyoming,

29726-403: The watershed is barren desert, and only about 1 percent is urbanized. Most of the Snake River watershed is public land, with the U.S. Forest Service managing the Nez Perce , Clearwater , Bitterroot , Umatilla , Wallowa–Whitman , Payette , Boise , Salmon–Challis , Sawtooth , Caribou–Targhee and Bridger–Teton National Forests that cover much of the northern and eastern parts of

29904-400: The watershed. The forests contain numerous designated wilderness areas, including the Sawtooth , Selway–Bitterroot , Frank Church-River of No Return , Gospel Hump , Hells Canyon , Teton and Gros Ventre . National Park Service land includes Craters of the Moon National Monument and Yellowstone and Grand Teton National Parks. Large areas of privately owned farmland are concentrated in

30082-439: The western Snake River watershed, while the Snake River Plain was a product of the Yellowstone volcanic hotspot . The river was further altered by catastrophic flooding in the most recent Ice Age , which created such features as the Snake River Canyon and Shoshone Falls . The Snake River once hosted some of the largest North American runs of salmon and other anadromous fish . For thousands of years, salmon fishing has played

30260-440: The western part of the watershed. The Snake River Plain is the largest area without mountains, but it still features rugged terrain, being crisscrossed by canyons formed by the Snake River and its tributaries. Due to the rain shadow effect of the Cascades , precipitation as a whole is scant, averaging 14 inches (360 mm) across the entire watershed. Most precipitation falls at higher elevations as snow, thus, most runoff in

30438-421: The year, increasing about 20 percent during snowmelt and decreasing about 20 percent with late summer irrigation diversions. Despite its great length, the Snake River accumulates most of its water in the lower one-fourth of its course. By the time it reaches Hells Canyon Dam , 247 miles (398 km) from the mouth, the mean annual discharge is about 19,000 cu ft/s (540 m /s) – just over

30616-419: The years following their removal to the reservation, the Shoshone-Bannock peoples suffered severely from hunger and disease, with high mortality. Hoping to relieve his people's suffering, Pocatello led a small group to a missionary farm in the Utah Territory to receive mass baptism and conversion to Mormonism . Although the Shoshone were baptized, the local settlers, primarily Mormon, agitated for removal of

30794-565: Was called Brotherton Indian Reservation and also Edgepillock or Edgepelick . The area was 3,284 acres (13.29 km ). Today it is called Indian Mills in Shamong Township . In 1764 the British government's Board of Trade proposed the "Plan for the Future Management of Indian Affairs". Although never adopted formally, the plan established the British government's expectation that land would only be bought by colonial governments, not individuals, and that land would only be purchased at public meetings. Additionally, this plan dictated that

30972-427: Was commissioned to haul supplies up the Snake River to Fort Taylor. Captained by veteran Oregon river pilot Len White, the Wright was the first steamboat to run on the Snake River and the Columbia above The Dalles . Two years later, Elias D. Pierce discovered gold to the east on Nez Perce treaty land. As thousands of fortune seekers flocked to the area, the city of Lewiston was founded in 1861, in violation of

31150-451: Was initiated by John Collier . It laid out new rights for Native Americans, reversed some of the earlier privatization of their common holdings, and encouraged tribal sovereignty and land management by tribes. The act slowed the assignment of tribal lands to individual members and reduced the assignment of "extra" holdings to nonmembers. For the following 20 years, the U.S. government invested in infrastructure, health care, and education on

31328-445: Was the Sioux War on the northern Great Plains , between 1876 and 1881, which included the Battle of Little Bighorn . Other famous wars in this regard included the Nez Perce War and the Modoc War , which marked the last conflict officially declared a war. By the late 1870s, the policy established by President Grant was regarded as a failure, primarily because it had resulted in some of the bloodiest wars between Native Americans and

31506-406: Was the same or similar to the Plains Indian common sign for "snake." The English name for the river was likely derived from this interpretation of the hand gesture, although it is uncertain when the name was first used. The first Euro-Americans to reach the Snake River watershed were the Lewis and Clark Expedition, who in August 1805 crossed the Continental Divide at Lemhi Pass and descended to

31684-458: Was under its Land Buy-Back Program as part of the government's settlement of the Cobell v. Salazar class action suit. The land purchased will be transferred into trust for the Shoshone-Bannock Tribes, to restore its traditional land. About 1.5 million acres of land has been put into trust for tribes under this program. The Shoshone and Bannock had long occupied the territory of Idaho and nearby areas. They were not disrupted by settlers until
