604-acre lake near Québec. The lake tops out around 105 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. The rest of this page walks each species through its year, using the map's own scoring.
Drawn out, this is 604 acres of water rimmed by 6.2 miles of bank. Index 1.8 on the shoreline: a few honest points and pockets, nothing labyrinthine. The shallow band under 15 ft claims about 33% of the surface — that's where the groceries are. Figure 2.4 mi of water from one end to the other, 1 mi at the beam. The water lies in La Tuque.

Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Warm water sends them out to 10 to 30 ft; cold water stacks them in 3 to 20 ft. Top water on the chart: Main-lake point, a point in the 14 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.

|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Main-lake point (14 ft) | Small inline spinner (gold), Tiny spoon |

The spot to know is Deep basin, a deep basin in about 103 ft of water that rates prime for lake trout in summer. Warm-month bites cluster around early morning. Throw a white tube jig (deep) or a magnum spoon on downrigger until the fish tell you otherwise.
