Freshwater · Spring and early fall; summer fish retreat to cold springs and shade
Brook Trout
Salvelinus fontinalis
A beautifully marked char native to eastern North America, at home in cold creeks, beaver ponds and backcountry lakes. Brook trout are willing biters on small spinners, worms and dry flies, and a favourite of beginners.

Identifying features
- Worm-like pale markings (vermiculations) across a dark olive back
- Red spots with blue halos scattered along the sides
- Square tail with a wavy pattern — brook trout are actually char
- Lower fins edged in white, backed by black; belly turns orange-red on spawning males
- Look-alike: lake trout are grey with pale bean-like spots, a deeply forked tail and no red spots
Habits
- Live only in cold, clean water and seek springs in summer heat
- Feed on insects, worms and small fish through the day
- Most active at dawn and dusk and on overcast days
- Hold in small groups in ponds, alone in tiny creeks
Distribution
Where to find them
- Plunge pools and undercut banks on small shaded creeks
- Beaver ponds, especially near the dam and inlet
- Spring holes and creek mouths in backcountry lakes
