96-acre lake near Québec. The lake tops out around 20 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.
On the chart, Lac Tourangeau draws 96 acres inside 1.5 miles of shoreline. A shoreline index of 1.1 says round and simple: fish relate to depth changes here, not shoreline features. About 56% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 0.5 mi long by 0.5 mi wide at the broadest reach. You'll find it in Charlevoix MRC. Closest neighbour on DepthScout: Petit lac aux Montagnais, 2 mi southeast of here.

Spring puts brook trout in skinny water — 2 to 15 ft is the zone. As the season builds they drop to 6 to 20 ft, wintering in 3 to 20 ft. Summer brook trout concentrate at Deep basin, a prime-rated deep basin around 20 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.
