234-acre lake near Québec. The lake tops out around 33 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. What the data behind the map says about each species, season by season:
The outline encloses 234 acres, worked by 2.8 miles of shoreline. The basin is a simple one (shoreline index 1.3) — close to a bowl, so the structure on the chart matters more than the bank. Roughly 56% of the water is 15 ft or less, the band where the food chain lives. Call it 1.2 mi long by 0.5 mi wide at the broadest reach. Le Granit MRC claims this one. Its nearest charted neighbour, Grand lac Saint-François, is 4 mi to the west.

Come spring, look for brook trout tight to the bank in 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. If you only fish one area, make it Break off the point: a drop-off around 10 ft that scores prime in summer. Best bite is early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Main-lake point (6 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | Break off the point (10 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 2 to 15 ft | midday & dawn | Main-lake point (6 ft) | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Break off the point (10 ft) | Small jigging spoon, Tungsten jig + plastic |
When the water first warms, rainbow trout slide up into 5 to 20 ft. Summer is an 8 to 30 ft game here, winter a 7 to 33 ft one. Start at Break off the point. It's a drop-off holding about 10 ft of water and rates prime come winter. The feeding windows run early morning and the evening. Keep a dodger + spoon (deep troll) or a flutter spoon rigged through the warm months.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |

The spring pattern is a shallow one: brown trout in 3 to 25 ft. As the season builds they drop to 10 to 33 ft, wintering in 5 to 33 ft. Top water on the chart: Break off the point, a drop-off in the 10 ft range, prime in summer. Time it for after dark and early morning. Summer baits: a spoon at the thermocline or a deep stickbait (night) gets it done.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 3 to 25 ft | dawn & dusk | Main-lake point (6 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |

The spring pattern is a shallow one: walleye in 4 to 15 ft. As the season builds they drop to 10 to 33 ft, wintering in 10 to 33 ft. Top water on the chart: Break off the point, a drop-off in the 10 ft range, prime in fall. Time it for the evening and early morning. Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) gets it done.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 4 to 15 ft | dusk & dawn | Main-lake point (6 ft) | 1/8 oz jig + minnow, Hair jig |

In spring, yellow perch run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 10 to 33 ft. Shallow bay flat is the standout, a weed flat at roughly 4 ft, rated prime for spring yellow perch. Time it for early morning. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 3 to 12 ft | midday & dawn | Shallow bay flat (4 ft) | Small jig + curly tail, Perch-pattern micro crank |

| Hiver | 10 to 33 ft | midday & dawn | Deep basin (33 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Early season northern pike use the shallows, holding in 2 to 8 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 5 to 15 ft. Put Shallow bay flat first on the milk run — a weed flat near 4 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
