4,813-acre lake near Québec. The lake tops out around 63 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. Every species below gets its seasonal read from the same numbers driving the chart.
Drawn out, this is 4,814 acres of water rimmed by 14.3 miles of bank. Index 1.5 on the shoreline: a few honest points and pockets, nothing labyrinthine. Roughly 63% of the water is 15 ft or less, the band where the food chain lives. Tip to tip the water measures near 4.3 mi with a 3.6-mi widest point. You'll find it in Rouyn-Noranda. Closest neighbour on DepthScout: Lac Osisko (no 2), 5 mi south of here.

The spring pattern is a shallow one: brook trout in 2 to 15 ft. As the season builds they drop to 10 to 30 ft, wintering in 3 to 20 ft. Top water on the chart: Sharp break, a drop-off in the 9 ft range, prime in summer. Time it for early morning and the evening. Summer baits: a small spoon fished deep or a trolled lake-clear wobbler + worm gets it done.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Main-lake point (4 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | Sharp break (9 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 2 to 15 ft | midday & dawn | Main-lake point (4 ft) | Small spoon (orange), Spinner |

Come spring, look for lake whitefish tight to the bank in 15 to 45 ft. They move out to 19 to 63 ft in summer and finish the year down in 19 to 63 ft. If you only fish one area, make it Deep basin: a deep basin around 61 ft that scores prime in summer. Best bite is early morning. A blade bait vertical or a small jigging spoon is the honest summer answer here.
