125-acre lake near Québec. The lake tops out around 90 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. Below is the species-by-species picture, pulled from the same data the map uses.
Traced from the shoreline, Lac Bourassa runs 125 acres with 1.8 miles of edge. The basin is a simple one (shoreline index 1.2) — close to a bowl, so the structure on the chart matters more than the bank. Littoral water — the productive band under ~15 ft — makes up 18% of this chart. Tip to tip the water measures near 0.7 mi with a 0.3-mi widest point. You'll find it in La Côte-de-Beaupré MRC. Closest neighbour on DepthScout: Lac Neville, 1 mi southwest of here.

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. Summer brook trout concentrate at Break off the point, a prime-rated drop-off around 22 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.
