Metolius Springs are located just north of Black Butte near the small unincorporated town of Camp Sherman in central Oregon, United States. The springs are the source of the Metolius River, which flows through the Deschutes National Forest emptying into Lake Billy Chinook. The flow from Metolius Springs is sufficient to create a full-flowing river, making the Metolius River one of the largest spring-fed rivers in the United States. The name of the springs comes from the Warm Springs or Sahaptin word mitula, meaning white salmon and referring to a light colored Chinook salmon and not a whitefish.
