Washington in the United States. The river's
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.
History
The river was named after the
Methow Native Americans (today part of the Confederated Tribes of the

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 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.

Mazama. Along the way, it collects the tributary streams of Robinson Creek and Lost River. In 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

The Methow Valley continues below Winthrop to
Twisp, where 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 the Columbia River at
Pateros. This part of the Columbia is the impoundment of
Wells Dam, a lake known as
Lake Pateros.

Translocation success was optimized by putting pairs of beavers together in man-made lodges that tended to keep them in the desired sites so that the beaver ponds would store rainwater, trap sediment and repair channel incision/erosion, serve as nurseries for
