Rivers and Mountains in Idaho

Rivers in Idaho

Bear River
The Bear River has a total length of 563 km and flows through the states of Idaho, Wyoming and Idaho. The Bear River is created in Utah by the confluence of the Hayden Fork and Stillwater Fork. From there it flows through the southwestern part of Wyoming, from there to Idaho and finally flows back to the Great Salt Lake in Utah. The Bear River is particularly important for agriculture because it is used very intensively for irrigation.

Bruneau River
The Bruneau River is an approx. 246 km long tributary of the Snake River. Its catchment area is the Jarbidge Mountains, from which it flows through Idaho (Owyhee County) and Nevada (Elko County). The Bruneau River is particularly popular with fans of white water: rapids, warm springs and the 370 m deep and 64 km long Bruneau Canyon make the area an ideal tour.

Salmon River
The Salomon River is a 684 km long river that once flows through central Idaho. It rises from the Sawtooth and Salmon River Mountains and has a height difference of approx. 230 m from source to mouth in the Snake River (on the Oregon border). It is considered the longest undamaged river in the United States and the longest that flows through a single state. Due to its rapid rapids, the Salmon River is particularly popular with fans of white water rafting, but it is not entirely safe. In some areas you can only go on the water with permission, because accidents on the river without recurrence are not uncommon.

Snake River
The Snake River is also known as the Shoshone River and has a length of approximately 1,674 km. It is a tributary of the Columbia River and flows through the states of Wyoming, Idaho, Oregon and Washington. The source of the river is in Yellowstone National Park and from there the river also flows through the Grand Teton National Park. The Snake River flows into the Columbia River near the city of Pasco. The Snake River flows through numerous deep canyons and forms many waterfalls, such as the over 60 m high Shoshone Falls.
