243-acre lake near Québec. The lake tops out around 74 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. Every species below gets its seasonal read from the same numbers driving the chart.
Drawn out, this is 243 acres of water rimmed by 3.4 miles of bank. The shoreline is moderately structured (index 1.6) — enough points and pockets to pattern.

Spring puts brook trout in skinny water — 2 to 15 ft is the zone. Warm water sends them out to 10 to 30 ft; cold water stacks them in 3 to 20 ft. Main-lake point is the standout, a point at roughly 13 ft, rated prime for spring brook trout. Plan around early morning and the evening in the warm months. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
