It then modifications course and streams northwest when it reaches the Palisades Reservoir on the Wyoming-Idaho Border. Near Rexburg, Idaho, the River once again modifications course and heads southwest towards Idaho Falls and Pocatello. After the American Falls Reservoir, the river streams primarily west up until Twin Falls, at which point it once again turns northwest.
The Snake River briefly crosses into Oregon around 60 miles west of Boise, Idaho. From there, the river cuts north and forms the whole northern half of the Idaho-Oregon Border. Near Lewiston, Idaho, the Snake River once again modifications course and starts to stream west into Washington state.

From the Snake River Plains to Hells Canyon near the Idaho-Oregon-Washington border, 10 significant rivers sign up with the Snake River. These consist of:
- Henry’s Fork (often called the North Fork of the Snake River)
- Portneuf River
- Raft River
- Malad River
- Salmon Falls Creek
- Bruneau River
- Owyhee River
- Boise River
- Malheur River
- Payette River

The Snake River winds its method through Hells Canyon, the inmost river canyon in North America. Although Hells Canyon just determines 125 miles, 5 tributaries sign up with the Snake River throughout this brief stretch.
