Brook Trout

Dark olive back with lighter worm-like vermiculations, red spots ringed in blue, white leading edges on lower fins, and a square (not forked) tail.

Cold headwater streams and deep spring-fed lakes 8–20°C. Boreal shield lakes north of Highway 17 hold the biggest fish.

• In May, cast a #1 gold Mepps in slack water below bubbling shallow riffles.
• Backcountry paddle-in lakes hold much bigger brookies than roadside lakes — the effort is the barrier that protects them.
• In September, target creek mouths — brookies stage before running up to spawn.

5 fish possession in most zones with 20–30 cm minimum sizes. Some Algonquin lakes are catch-and-release only.

Always confirm before your trip: Ontario Fishing Rules & Licences.
