Bend Oregon is home to some of the largest Bull Trout in the Pacific Northwest and the United States. The Metolius River which is about a one hour drive west of Bend is the spawning ground to a great Bull Trout fishery.

The Metolius River springs from the ground at the base of Black Butte and flows into Lake Billy Chinook. Lake Billy Chinook is technically a reservoir as it is backed up my Round Butte Dam.
