21-acre lake near Québec. The lake tops out around 28 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.
On the chart, Lac du Sud-Ouest (no 1) draws 21 acres inside 0.8 miles of shoreline, broken up by an island. The basin is a simple one (shoreline index 1.3) — close to a bowl, so the structure on the chart matters more than the bank. About 85% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 0.3 mi long. You'll find it in Charlevoix MRC. For a second option, Lac du Sud-Ouest (no 2) lies 1 mi south.

The spring pattern is a shallow one: brook trout in 2 to 15 ft. As the season builds they drop to 8 to 28 ft, wintering in 3 to 20 ft. Top water on the chart: Deep basin, a deep basin in the 28 ft range, prime in summer. Time it for early morning and the evening. Summer baits: a small spoon fished deep or a trolled lake-clear wobbler + worm gets it done.
