361-acre lake near Québec. The lake tops out around 112 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.
On the chart, Lac Mercier draws 361 acres inside 4 miles of shoreline. Index 1.5 on the shoreline: a few honest points and pockets, nothing labyrinthine. Littoral water — the productive band under ~15 ft — makes up 19% of this chart. The basin spans about 1.8 mi end to end and 0.5 mi across at its widest. You'll find it in Les Laurentides MRC.

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 Main-lake point, a point in about 11 ft of water that rates prime 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.

Top water on the chart: Deep basin, a deep basin in the 111 ft range, prime in summer. Fish it in early morning and you'll meet the bite. Throw a white tube jig (deep) or a magnum spoon on downrigger until the fish tell you otherwise.

Top water on the chart: Break off the point, a drop-off in the 6 ft range, prime in winter. Time it for early morning and the evening. Summer baits: a dodger + spoon (deep troll) or a flutter spoon gets it done.

It's a drop-off holding about 6 ft of water and rates prime come spring. The feeding windows run early morning. Keep a jigging spoon vertical or a tube jig (smelt) rigged through the warm months.
