The Snake River is a 1,735 km long tributary of the Columbia River in the northwestern United States .

The Snake River has its source on the continental divide in Yellowstone National Park , then flows south in Wyoming through Grand Teton National Park . Behind the Snake River Canyon , it turns west and reaches the Snake River Plain , a plain that curves for about 600 km through southern Idaho . It flows past the towns of Idaho Falls , Pocatello , Twin Falls, and Boise , and forms several reservoirs such as the American Falls Reservoir . At the height of Twin Falls, the Snake River forms the 70 m high Shoshone Falls , also called Niagara of the west . Then it flows further north and forms part of the Idaho- Oregon border .

South of Lewiston , the Snake River forms the Hells Canyon , which is one of the deepest canyons in the world with a depth of up to 2,410 m . After the confluence with the Clearwater River , the river in the US state of Washington is dammed several times to generate energy and finally flows into the Columbia River at Pasco . The Owyhee Dam , the Dworshak Dam and the Teton Dam , which was not rebuilt after a dam breach in 1976, are located in the catchment area of ​​the Snake River .

The river used to be called the Shoshone River and also the Lewis River after the Lewis and Clark Expedition explored part of the river in 1805. The name Snake possibly comes from an S-shaped hand sign of Shoshone - Indians , which has a floating salmon symbolized.

On the upper reaches of the river, around 670 km of the Snake River itself and its tributaries in Yellowstone and Grand Teton National Park are designated as National Wild and Scenic River , in the further course another 107 km below the Hells Canyon Dam in the Hells Canyon of the Snake River same status.
