Willamette River

The Willamette River is a tributary of the Columbia River with a length of about 386 kilometers in northwestern Oregon. It is formed by the confluence of Coast Fork Willamette River and Middle Fork Willamette River near Springfield ( Oregon) and ends at Portland in the Columbia River.

The Willamette Valley formed by the river was one of the first settlement areas on the Oregon Trail to the west pulling pioneers and settlers in the Pacific Northwest. In the 20th century, the agriculture specialized in viticulture (see: Willamette Valley AVA).
