The Methow River ( / ˈ m ɛ t h aʊ / MET -how ) is a tributary of the Columbia River in northern Washington in the United States. The river's 1,890-square-mile (4,900 km) watershed drains the eastern North Cascades , with a population of about 5,000 people. The Methow's watershed is characterized by relatively pristine habitats, as much of the river basin is located in national forests and wildernesses. Many tributaries drain the large Pasayten Wilderness . An earlier economy based on agriculture is giving way to one based on recreation and tourism.
18-758: The river was named after the Methow Native Americans (today part of the Confederated Tribes of the Colville Indian Reservation ). The name "Methow" comes from the Okanagan placename /mətxʷú/ , meaning "sunflower (seeds)". The Native American name for the river was Buttlemuleemauch , meaning "salmon falls river". In 1841 the Wilkes Expedition named the river "Barrier River". Alexander Ross said
36-602: A Native American tribe that lived along the Methow River , a tributary of the Columbia River in northern Washington . The river's English name is taken from that of the tribe. The name "Methow" comes from the Okanagan placename /mətxʷú/ , meaning "sunflower (seeds)". The tribe's name for the river was Buttlemuleemauch , meaning "salmon falls river". The Methow were a relatively small tribe, with an estimated population of 800 in 1780 and 300 in 1870. Today,
54-722: The Colville Indian Reservation . The Okanogan River enters the Columbia River from the north, 5 miles (8 km) east of Brewster , between the Wells Dam (downstream) and the Chief Joseph Dam (upstream). The reservoir behind Wells Dam, into which the Okanogan empties, is called Lake Pateros . The Okanogan River receives the Similkameen River from the west near Oroville. It receives Omak Creek from
72-727: The Okanagan River in Canada ) is a tributary of the Columbia River , approximately 115 mi (185 km) long, in southern British Columbia and north central Washington . It drains a scenic plateau region called the Okanagan Country east of the Cascade Range and north and west of the Columbia, and also the Okanagan region of British Columbia. The Canadian portion of the river has been channelized since
90-675: The Canada–US border, a journey of 120 miles (190 km). The Methow Beaver Project is a partnership between the U.S. Forest Service , the Washington Department of Fish and Wildlife and the Methow Salmon Recovery Foundation. Beaver were nearly exterminated in the Methow watershed by the early 1900s by fur trappers. Methow people The Methow ( / ˈ m ɛ t h aʊ / MET -how ) are
108-503: The Columbia River at Pateros . This part of the Columbia is the impoundment of Wells Dam , a lake known as Lake Pateros . In Robertson v. Methow Valley Citizens Council (a 1989 Stevens decision) the Rehnquist Court concluded that NEPA does not require a fully developed plan detailing what steps will be taken to mitigate adverse environmental impacts and does not require a " worst case analysis ." In addition, we hold that
126-599: The Forest Service has adopted a permissible interpretation of its own regulations. Since 2007, the Methow Beaver Project has translocated over 240 "problem" beaver ( Castor canadensis ) into 51 suitable sites in various headwater tributaries of the Methow watershed. The sites were selected using satellite imagery and computer modelling. Translocation success was optimized by putting pairs of beavers together in man-made lodges that tended to keep them in
144-544: The Methow River and its tributaries, such as Methow Pass and Twisp Pass. State Route 20 utilizes Washington Pass and Rainy Pass , also in the general areas of headwater streams. The Pacific Crest Trail follows the uppermost reach of the Methow River, until the river turns east, flowing into the Methow Valley near Mazama . Along the way, it collects the tributary streams of Robinson Creek and Lost River. In
162-577: The Methow River is joined by another important tributary, the Twisp River . Flowing from the west, the Twisp River drains the mountains south of Washington Pass as well as the eastern slopes of Sawtooth Ridge, a major mountain range with some of Washington state's highest peaks (such as Star Peak and Mt Bigelow). Downriver from Twisp, the Methow River passes by the communities of Carlton and Methow, receiving several minor tributaries, before joining
180-615: The Methow Valley, between Mazama and Winthrop , the Methow River is joined by Early Winters Creek, Cedar Creek, Goat Creek, and Wolf Creek. The Chewuch River joins at Winthrop. One of the Methow's larger tributaries, the Chewuch River, and its many tributaries drain large parts of the Pasayten Wilderness to the north. One of its headwater streams, Cathedral Creek, reaches nearly to British Columbia , Canada . The Methow Valley continues below Winthrop to Twisp , where
198-750: The Methow live primarily on the Colville Indian Reservation in Washington, where they form part of the Confederated Tribes of the Colville Reservation, which is recognized by the United States government as an American Indian Tribe . The Methow now speak English. Their endangered language, known as Colville-Okanagan , spoken only by older adults, is a part of the Southern Interior Salish linguistic branch.

One beaver that was PIT (passive integrated transponder) tagged and released in the upper part of the Methow Valley swam to the mouth of the Methow River, then up the Okanogan River almost to
234-486: The east near Omak, Tonasket Creek from the east near Oroville and Bonaparte Creek at Tonasket which flows from Bonaparte Lake near Wauconda and also from Aeneas Valley west of the Sanpoil . It occasionally receives water from Salmon Creek at the town of Okanogan but much of the year this water is diverted for irrigation . The river takes its name from the Okanagan (or Syilx ) placename [uk naqín]. The name Okanagan
252-561: The mid-1950s. The Okanagan River rises in southern British Columbia, issuing out of the southern end of Okanagan Lake , which is on the north side of the city of Penticton . It flows south past Penticton, through Skaha Lake , past Okanagan Falls , through Vaseux Lake , and past Oliver to Osoyoos and Osoyoos Lake , which spans the Canada–United States border and has its outlet into the Okanogan River at Oroville , on
270-533: The native name was Buttle-mule-emauch. In 1811 David Thompson met the tribe living along the river and wrote their name as Smeetheowe. In 1853 George Gibbs called the river Methow or Barrier. The Methow River, along with its tributaries the Twisp River, Cedar Creek, and Early Winters Creek, originates in a cluster of high mountains including Golden Horn , Tower Mountain , Cutthroat Peak , Snagtooth Ridge , Kangaroo Ridge , Early Winters Spires , and Liberty Bell Mountain . Several mountain passes are associated with
288-751: The river's confluence with the Columbia. The isolation and pressures caused by the War of 1812 forced the PFC to sell its property and assets to its Canadian rivals, the North West Company . The NWC was in turn merged into the Hudson's Bay Company in 1821, the latter company maintaining a presence at Fort Okanogan until the 1850s. During the Fraser Canyon Gold Rush of 1858–1859, parties of armed miners, often at conflict with native peoples in
306-603: The southern shore of the lake, in Okanogan County . At the border the river's name (and the region and also the name of the Okanagan Highland ) changes spelling from Okanagan to Okanogan. Average annual flow of the river at this point is 643 cfs (18.2 m³/s). From Oroville the Okanogan River flows south through the Okanogan County, past Okanogan and Omak . It forms the western boundary of
324-736: Was subsequently applied to the Syilx people themselves. Early maps of the fur trade era show the Okanagan River as the "Caledonia River", a name conferred as it was the connecting route between the Columbia District and the New Caledonia Fur District (which began north of Okanagan Lake). Fort Okanogan , a fur-trading post opened by the Pacific Fur Company (PFC) late in 1811, was located at
