172-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. Here's the year, species by species, as the scoring engine sees it.
The outline encloses 172 acres, worked by 2.1 miles of shoreline. A shoreline index of 1.1 says round and simple: fish relate to depth changes here, not shoreline features. Roughly 36% of the water is 15 ft or less, the band where the food chain lives. Figure 0.8 mi of water from one end to the other, 0.5 mi at the beam. Portneuf MRC claims this one. Lac du Pont de Bois sits 2 mi south — the closest neighbouring chart.

Spring brook trout on Lac des Aulnes hold shallow, usually 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. Put Shallow bay flat first on the milk run — a weed flat near 6 ft that grades good for spring. The feeding windows run early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.

Come spring, look for lake trout tight to the bank in 10 to 40 ft. They move out to 15 to 50 ft in summer and finish the year down in 13 to 50 ft.

A white tube jig (deep) or a magnum spoon on downrigger is the honest summer answer here.
