36-acre lake near Québec. The lake tops out around 46 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 follows comes from the same scoring engine that paints the spots above.
Drawn out, this is 36 acres of water rimmed by 0.9 miles of bank. Nearly circular (index 1.1), so the story is the bottom, not the bank. The shallow band under 15 ft claims about 42% of the surface — that's where the groceries are. End to end it runs roughly 0.3 mi, about 0.3 mi across. You'll find it in Matawinie MRC. The nearest mapped water is Lac Herron, 1 mi to the south.

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: Break off the point, 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 |

Start shallow in spring: landlocked salmon sit in 1 to 15 ft that time of year. Summer pushes them deeper, 14 to 46 ft, and winter fish settle into 10 to 40 ft. The spot to know is Deep basin, a deep basin in about 45 ft of water that rates prime for landlocked salmon in summer. Warm-month bites cluster around early morning and the evening. Throw a dodger + streamer down deep or a thin spoon on lead core until the fish tell you otherwise.

|---|---|---|---|---|
| Printemps | 1 to 15 ft | dawn & dusk | Main-lake point (4 ft) | Streamer flies (Grey Ghost) off boards, Thin spoon (Mooselook style) |

Spring walleye on Lac Leech hold shallow, usually 4 to 15 ft. By summer they slide out to 15 to 35 ft, and by winter most fish are in 20 to 40 ft. The chart's best answer is Break off the point — drop-off, 9 ft, prime for fall. Prime time lands in the evening and early morning. The summer box starts with a crawler harness on bottom bouncer or a deep crankbait (trolled).
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 4 to 15 ft | dusk & dawn | Main-lake point (4 ft) | 1/8 oz jig + minnow, Hair jig |

Early season yellow perch use the shallows, holding in 3 to 12 ft. Summer is a 10 to 30 ft game here, winter a 15 to 35 ft one. The chart's best answer is Shallow bay flat — weed flat, 4 ft, prime for spring. Best bite is early morning. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.
| 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 |

In spring, northern pike run shallow here, mostly 2 to 8 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 5 to 15 ft for winter. Spring northern pike concentrate at Shallow bay flat, a prime-rated weed flat around 4 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a bucktail or a weedless spoon over cabbage most summer days.
