Bull Trout

Bull trout in Oregon are actually char, not true trout, listed as a threatened species under the Endangered Species Act with very limited distribution in Oregon.

Physical Characteristics:
  • Distinguished by their gray-green coloration infused with small white or pale yellow spots, with some deep orange to red spots along their sides and distinctive white leading edges on their fins.
  • The largest specimens typically come from lacustrine environments.

What to know

Habitat Distribution

  • Most common in high mountainous areas, typically found in headwaters and deep pools of cold rivers.
  • They require the 'four Cs' - cold, clean, complex, and connected habitats.

Key Locations

  • Bull trout can only be legally targeted in Oregon at the Metolius River and the Metolius arm of Lake Billy Chinook.
  • Viable populations mainly in the Metolius River system and the Metolius arm of Lake Billy Chinook in Central Oregon.

Specific Spots

  • Target deep pools with complex cover, log jams, boulder gardens, and areas where tributaries meet main rivers.
  • Focus presentations around creek mouths and transitions from shallow to deep water.
