60-acre lake near Québec. The lake tops out around 53 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.
The outline encloses 60 acres, worked by 1.2 miles of shoreline. A shoreline index of 1.1 says round and simple: fish relate to depth changes here, not shoreline features. About 48% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The basin spans about 0.5 mi end to end and 0.3 mi across at its widest. It sits in Lac-Saint-Jean-Est MRC. If the bite dies, Lac Suzor-Coté is 2 mi to the north.

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 Shallow bay flat first on the milk run — a weed flat near 7 ft that grades good for spring. 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.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Shallow bay flat (7 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | open water | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 2 to 15 ft | midday & dawn | open water | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Shallow bay flat (7 ft) | Small jigging spoon, Tungsten jig + plastic |
When the water first warms, lake trout slide up into 10 to 40 ft. By summer they slide out to 16 to 53 ft, and by winter most fish are in 13 to 53 ft. If you only fish one area, make it Deep basin: a deep basin around 52 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.

The spot to know is Deep basin, a deep basin in about 52 ft of water that rates prime for lake whitefish in summer. Warm-month bites cluster around early morning. Throw a blade bait vertical or a small jigging spoon until the fish tell you otherwise.
