Metolius Arm of Lake Billy Chinook (Area 4)


A true success story, the bull trout population has rebounded from extremely low numbers to become one of the strongest most robust populations in the country. Lake Billy Chinook is one of the only areas where you can legally retain a bull trout. In addition to being the premiere location to catch bull trout and kokanee, there are also rainbow trout, smallmouth bass and other species in the lake. The lake is closed to all fishing from the signed point upstream, approximately 350 yards, to the cable crossing on the Metolius River.
