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 29 miles (47 km) 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.
