Knife River (Snake River tributary)

The Knife River is a river located in southwestern Washington, United States. It is a tributary of the Snake River, flowing into it near the town of Burbank, Washington. The Knife River is relatively short and drains a small watershed area primarily characterized by agricultural lands and shrub-steppe vegetation.

While not a major river system, the Knife River and its surrounding riparian zone provide important habitat for local wildlife. Its water resources are used for irrigation purposes in the agricultural region.

The name "Knife River" is believed to be derived from the sharp, angular rocks found along its course, which were reminiscent of knives to early settlers or Native Americans. Detailed historical information regarding the specific naming origin remains somewhat limited.
