71-acre lake near Québec. The lake tops out around 5 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 is how the season plays out for each species, straight from the data behind the map.
On the chart, Lac Grandpré draws 71 acres inside 1.6 miles of shoreline. 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. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. The basin spans about 0.6 mi end to end and 0.3 mi across at its widest. You'll find it in La Côte-de-Beaupré MRC. Closest neighbour on DepthScout: Lac Nadreau, 1 mi south of here.

Spring puts brook trout in skinny water — 1 to 5 ft is the zone. Summer fish stay in 2 to 5 ft, and winter fish hold in 1 to 5 ft. Summer brook trout concentrate at Deep basin, a prime-rated deep basin around 5 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.

Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
