Metolious River In Oregon Stock Image

The Metolius River (pronounced muh TOLL ee us) is a tributary of the Deschutes River (through Lake Billy Chinook) in Central Oregon, United States, near the city of Sisters. The river flows north from springs near Black Butte, then turns sharply east, descending through a series of gorges before ending in the western end of the lake. The name of the river comes from the Warm Springs or Sahaptin word mitula, meaning white salmon and referring to a light colored Chinook salmon and not a whitefish.
