Snake River – Oregon & Idaho Border

The Snake River is a major tributary to the Columbia River with headwaters located in Yellowstone National Park in western Wyoming.  The Snake flows mostly east to west across southern Idaho until it turns north and begins its journey through Hell’s Canyon and finally discharges into the Columbia. The river has an average discharge of 54,000 cubic feet per second.

The river provides irrigation water for crops, hydroelectric power, boating, fishing, and many iconic Idaho scenic vistas.

The Snake River is the natural landmark used to indicate approximately 200 miles of the border between the states of Idaho and Oregon.
