58-acre lake near Québec. The lake tops out around 53 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. Species by species, here's what the data says the year looks like.
On the chart, Lac de la Corneille draws 58 acres inside 1.3 miles of shoreline. 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. 43% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. End to end it runs roughly 0.6 mi, about 0.2 mi across. You'll find it in Maskinongé MRC. Closest neighbour on DepthScout: Lac Gentil, 1 mi north of here.

Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 3 to 20 ft. The spot to know is Shallow bay flat, a weed flat in about 7 ft of water that rates good for brook trout in spring. Warm-month bites cluster around early morning and the evening. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.
