Bull Trout (Salvelinus confluentus)

Body Type: A robust, large-headed char with a rounded, blunt snout. The body is olive-green to dark gray with pale yellow, orange, and red spots on the sides — no dark spots or halos. The lower fins have the white and black edging characteristic of char. Bull Trout are often confused with Brook Trout but lack the vermiculations (worm-like markings) on the back.

Preferred Water Temperature: 45°F–55°F. Among the most cold-dependent salmonids in North America. Require clean, cold water with temperatures that rarely exceed 55°F. Their presence indicates excellent water quality and cold water connectivity.

Habitat: Cold, clear mountain streams and deep glacial lakes in the Pacific Northwest and Northern Rocky Mountains. Require unobstructed migration corridors between spawning tributaries and rearing habitat. Found in the Columbia River drainage, Montana, Idaho, Washington, Oregon, and British Columbia. Federally listed as a threatened species — special regulations apply.

Best Lures: Large streamers on a fly rod are the classic approach — large Woolly Buggers, Muddler Minnows, and sculpin imitations. Large spoons produce in deep lakes. Large inline spinners work in rivers. Live and cut bait rigs produce big fish where legal.

Best Baits: Large live minnows are excellent where regulations allow. Nightcrawlers produce in streams. Sucker meat works well in some fisheries. Always check local regulations — Bull Trout have strict catch-and-release requirements in most waters.

Size & Weight: Stream fish typically 12–20 inches. Lake-dwelling fish reach 10–20 lbs. World record: 32 lbs from Lake Pend Oreille, Idaho.
