Montreuil Lake maps at 44 acres behind 1.5 miles of shoreline. With a 1.7 development index there's bank structure worth casting at, in moderation. Littoral water — the productive band under ~15 ft — makes up 39% of this chart, as modeled. The basin spans about 0.6 mi end to end and 0.2 mi across at its widest. Nipissing District claims this one. Its nearest charted neighbour, Ducharme Lake, is 1 mi to the east.
Early season brook trout use the shallows, holding in 2 to 15 ft. Summer is a 10 to 30 ft game here, winter a 3 to 20 ft one. The chart's best answer is Break off the point — drop-off, 33 ft, prime for summer. Best bite is early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.
