13-acre lake near Québec. The lake tops out around 59 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.
The outline encloses 13 acres, worked by 0.6 miles of shoreline. At index 1.2 the outline is almost a bowl — read the depth changes, not the shoreline. Littoral water — the productive band under ~15 ft — makes up 11% of this chart. It sits in Papineau MRC. Lac Clair sits 0 mi east — the closest neighbouring chart.

Early season brook trout use the shallows, holding in 2 to 15 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 3 to 20 ft. Put Shoreline break first on the milk run — a drop-off near 8 ft that grades prime for winter. In summer the feeding windows fall in early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.

When the water first warms, lake trout slide up into 10 to 40 ft. By summer they slide out to 18 to 59 ft, and by winter most fish are in 15 to 59 ft. If you only fish one area, make it Deep basin: a deep basin around 59 ft that scores prime in summer. In summer the feeding windows fall in early morning. Keep a white tube jig (deep) or a magnum spoon on downrigger rigged through the warm months.
