48-acre lake near Québec. The lake tops out around 40 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.
The outline encloses 48 acres, worked by 1.2 miles of shoreline. At index 1.2 the outline is almost a bowl — read the depth changes, not the shoreline. Roughly 27% of the water is 15 ft or less, the band where the food chain lives. The basin spans about 0.5 mi end to end and 0.2 mi across at its widest. Portneuf MRC claims this one. Its nearest charted neighbour, Deuxième lac Jumeau, is 0 mi to the southeast.

Early season brook trout use the shallows, holding in 2 to 15 ft. Summer is a 10 to 30 ft game here, winter a 3 to 20 ft one. The chart's best answer is Main-lake point — point, 10 ft, prime for spring. Best bite is 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 | Main-lake point (10 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | Break off the point (32 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 2 to 15 ft | midday & dawn | Main-lake point (10 ft) | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Shallow bay flat (5 ft) | Small jigging spoon, Tungsten jig + plastic |
In spring, walleye run shallow here, mostly 4 to 15 ft. Summer pushes them deeper, 15 to 35 ft, and winter fish settle into 20 to 40 ft. Break off the point is the standout, a drop-off at roughly 32 ft, rated prime for fall walleye. Time it for the evening and early morning. You won't need more than a crawler harness on bottom bouncer or a deep crankbait (trolled) most summer days.

|---|---|---|---|---|
| Printemps | 4 to 15 ft | dusk & dawn | Main-lake point (10 ft) | 1/8 oz jig + minnow, Hair jig |

The spring pattern is a shallow one: yellow perch in 3 to 12 ft. As the season builds they drop to 10 to 30 ft, wintering in 15 to 35 ft. Top water on the chart: Shallow bay flat, a weed flat in the 5 ft range, prime in spring. Time it for early morning. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 3 to 12 ft | midday & dawn | Shallow bay flat (5 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Été | 10 to 30 ft | dawn | Break off the point (32 ft) | Drop-shot micro plastics, Small spoon tipped with worm |

When the water first warms, northern pike slide up into 2 to 8 ft. By summer they slide out to 8 to 20 ft, and by winter most fish are in 5 to 15 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 5 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.

|---|---|---|---|---|
| Printemps | 2 to 8 ft | midday & dawn | Shallow bay flat (5 ft) | #5 inline spinner, Spoon (red/white) |
