Bull Trout
Bull trout are one of the most ecologically sensitive and beautiful fish in the Pacific Northwest — a true indicator of wild, cold, pristine water. A member of the char family, bull trout require some of the coldest, cleanest river systems to survive, making them a species that demands both skill and deep respect from fly fishers. Targeting bull trout is a privilege, and at NWFFO, we encourage all anglers to practice careful catch-and-release when pursuing these remarkable fish.
Where You Can Legally Target Bull Trout
Bull trout are a federally threatened species under the Endangered Species Act, and legal targeting opportunities in Oregon are extremely limited. Always check current ODFW regulations before fishing — most waters where bull trout are present are closed to targeting them entirely.
In Oregon, there are currently only two waters where anglers may legally target bull trout:
- Metolius River — one of Oregon’s most important bull trout rivers; a cold, spring-fed system that supports a significant population and offers a rare and special fly fishing experience
- Lake Billy Chinook — the reservoir at the confluence of the Metolius, Deschutes, and Crooked rivers; bull trout can be targeted here by boat and from shore
If you encounter bull trout incidentally while fishing other waters, handle them with extreme care and release them immediately.
Recommended Gear
Bull trout are predatory fish that respond best to large streamer presentations.
Rods
A 9-foot 6 or 7-weight is ideal for bull trout streamer fishing — enough power to cast large flies and handle strong fish in heavy current. A sink-tip line is often necessary to get flies down to where bull trout hold in deeper pools.
Reels & Lines
A large-arbor reel with a smooth drag is important — bull trout are powerful fish. A sink-tip or full-sink line gets large streamers into the strike zone in deeper, colder water where bull trout hold.

Leaders & Tippet
Keep leaders short and strong for bull trout streamer fishing — 6-7 feet of 10-12 lb fluorocarbon is standard. Bull trout aren’t leader-shy; they’re ambush predators focused on the fly’s movement.
Waders & Boots
Quality breathable waders and studded wading boots are essential for the cold, rocky waters of the Metolius. Felt or rubber soles with studs provide grip on slick basalt.
Flies That Work
Bull trout are aggressive predators that key on large baitfish and other trout. Large, flashy streamers are the most effective approach.
Streamers
Articulated Leech patterns, Intruder-style flies, Sculpzilla, Slumpbuster, large Woolly Buggers — olive, black, and white are productive colors
Attractor Patterns
Large Stimulators and Muddlers can draw aggressive strikes from bull trout in shallower Metolius water during summer
A Note on Bull Trout Conservation
Bull trout are federally threatened, and legal targeting opportunities are extremely limited. Never intentionally target bull trout outside of the Metolius River and Lake Billy Chinook. Always verify current ODFW regulations before fishing, handle fish with care, keep them in the water as much as possible, and release them quickly. These fish are worth protecting for future generations of PNW anglers.
