Brook Trout (Salvelinus fontinalis)

Body Type: Arguably the most beautiful North American freshwater fish. Olive-green back covered with pale worm-like markings (vermiculations). Sides have red spots surrounded by vivid blue halos. The belly and lower fins are orange-red, with the lower fins distinctively edged in white followed by black — a unique pattern found in no other trout species.

Preferred Water Temperature: 45°F–60°F. The most cold-sensitive trout species. Feed most actively at 54°F–58°F. Cannot survive extended periods above 65°F — their presence in a stream is an indicator of pristine water quality.

Habitat: Cold, spring-fed headwater streams, beaver ponds, and glacial lakes with exceptional water clarity and purity. Highly sensitive to pollution, siltation, and warm temperatures. Native to the Appalachians and Eastern Canada; widely stocked in cold Western mountain streams and high Sierra lakes above 8,000 feet.

Best Lures: Small inline spinners (size 0–2) in gold or silver are the top producers. Tiny gold or silver spoons like the Phoebe (1/16 oz) work in small streams. Dry flies and wet flies on a fly rod are the traditional approach — Elk Hair Caddis, Adams, and Royal Wulff are classics. Micro jigs in chartreuse or pink work in clear pools. Small floating Rapalas work in deeper pools and beaver ponds.

Best Baits: Nightcrawlers and small red worms are the universal top bait — keep them small. Single salmon eggs produce in flowing water. Wax worms and mealworms are excellent in cold conditions. Live crickets and grasshoppers work in summer. Small live minnows catch the larger Brook Trout in beaver ponds.

Size & Weight: Stream fish typically 6–10 inches and under 0.5 lbs. Beaver pond and lake fish reach 1–3 lbs. World record: 14 lbs 8 oz from the Nipigon River, Ontario. Sea-run "Salters" reach 4–5 lbs.
