What are the most important rivers in Oregon?

The first major waterway would be the Columbia River that forms two/thirds of Oregon's northern border with Washington. Its headwaters start in Canada and it flows south and west then empties into the Pacific Ocean just west of Astoria, Oregon. The second major waterway would be the Willamette River with its headwaters south of Eugene, Oregon, it flows north and empties into the Columbia River just north of Portland, Oregon.
