40-acre lake near Québec. The lake tops out around 80 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. The season-by-season read for each species follows, from the map's own numbers.
Drawn out, this is 40 acres of water rimmed by 1 miles of bank. Its 1.1 shoreline index means few bank features; the contours below do the pattern work. Littoral water — the productive band under ~15 ft — makes up 6% of this chart. The basin spans about 0.4 mi end to end and 0.2 mi across at its widest. You'll find it in Les Laurentides MRC. The nearest mapped water is Lac Monroe, 1 mi to the north.

Spring puts brook trout in skinny water — 2 to 15 ft is the zone. As the season builds they drop to 10 to 30 ft, wintering in 3 to 20 ft. Spring brook trout concentrate at Shallow bay flat, a good-rated feeding flat around 9 ft. Warm-month bites cluster around early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
