48-acre lake near Québec. The lake tops out around 50 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. What follows comes from the same scoring engine that paints the spots above.
The drawn water covers 48 acres wrapped in 1.2 miles of bank. Its 1.3 shoreline index means few bank features; the contours below do the pattern work. Roughly 18% of the water is 15 ft or less, the band where the food chain lives. Tip to tip the water measures near 0.6 mi with a 0.2-mi widest point. La Côte-de-Beaupré MRC claims this one. Its nearest charted neighbour, Lac Ti-Coq, is 1 mi to the west.

When the water first warms, brook trout slide up into 2 to 15 ft. Summer is a 10 to 30 ft game here, winter a 3 to 20 ft one. Start at Shallow bay flat. It's a feeding flat holding about 9 ft of water and rates good come spring. The feeding windows run early morning and the evening. Keep a small spoon fished deep or a trolled lake-clear wobbler + worm rigged through the warm months.
