Conservation note

The Metolius holds bull trout — a federally threatened char, catch-and-release only, to be released immediately and never targeted on or near redds. Bull trout poaching is a live concern here. We surface bull trout as present, but we do not score them as a catch target. Keep every fish wet, fish barbless above Bridge 99, and stay off the spawning closures.
