Brook Trout

Often called 'brookies,' these beautiful char are the ultimate prize for anglers seeking tranquility and aggressive strikes in remote waters. They are native to Eastern North America but have been widely introduced throughout the West, prized for their willingness to strike flies and small lures with reckless abandon.

Anglers target brook trout not just for their striking coloration—featuring vermiculated 'worm-like' patterns and bright red spots with blue halos—but for their role as an indicator of supreme water quality. Catching them requires finesse, stealth, and an understanding of how they position themselves in current to intercept drifting insects.

• Dark green to brown back with cream-colored worm-like markings called vermiculations.
• Bright red spots surrounded by distinctive blue halos on the flanks.
• Lower fins feature a stark white leading edge followed by a black line and orange hue.
• Possesses a square-shaped tail compared to the forked tail of other trout species.
• Member of the char family, often showing a slightly lighter belly color than trout.

Brook trout are opportunistic predators that primarily feed on aquatic insects, crustaceans, and occasionally small fish. They are most active during the low-light periods of dawn and dusk, frequently retreating to deep, shaded pools or undercut banks during the midday heat. While generally aggressive when food is scarce, they become highly territorial in shallow riffles. During the fall, their movement is dictated by the urge to migrate upstream toward spawning grounds, often congregating in large pools at the base of barriers.

Brook trout spawn in the autumn, typically between September and November depending on latitude and elevation. They require cold, oxygenated water ranging from 40 to 50 degrees Fahrenheit, selecting clean gravel beds in spring-fed tributaries for egg deposition. During this period, trout display heightened aggression as males compete for females, but they are generally less interested in feeding. Ethical anglers should avoid targeting fish on their redds to ensure successful recruitment for future seasons.
