What this answer means on the water

The Zone 11 rule is the default answer for brook trout, not a promise that every lake, river, sanctuary, or stocked water follows the same rule. Before keeping fish, check the exact waterbody name, any exception table, the licence class you are fishing under, and the size notes above.

TackleDex is built for that last-mile check: open the app at the launch, verify the species and zone, then keep the answer with your private catch log instead of guessing from memory.

Fine details that can get you in trouble

Waterbody exceptions, sanctuaries, and special closures can override this zone-wide answer.
Check the exact Fisheries Management Zone if the lake or river sits near a boundary.
Sport and conservation licence limits are different; possession limits still apply after you leave the water.
Sport: not more than 1 greater than 31 cm. Conservation: none greater than 31 cm
Aggregate limit: S-5/C-2 for all trout and salmon combined
