Columbia River

This wide, fast-flowing river begins in the Canadian Rockies of southeast British Columbia, Canada, flowing south through the State of Washington, then forming the natural border between Washington and Oregon. It ends in the Pacific Ocean and it is (1,152 miles) (1,857 km) in length.

Hydroelectric power development in the river basin brought inexpensive electricity to the Pacific Northwest, but it severely affected salmon spawning and local fish migration.
