180-acre lake near Québec. The lake tops out around 30 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.
The drawn water covers 180 acres wrapped in 2 miles of bank. A shoreline index of 1.1 says round and simple: fish relate to depth changes here, not shoreline features. Littoral water — the productive band under ~15 ft — makes up 57% of this chart. Tip to tip the water measures near 0.7 mi with a 0.6-mi widest point. It sits in Antoine-Labelle MRC. Its nearest charted neighbour, Lac Saint-Joseph, is 1 mi to the southeast.

Come spring, look for brook trout tight to the bank in 2 to 15 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 3 to 20 ft. Start at Deep basin. It's a deep basin holding about 29 ft of water and rates prime come summer. Prime time lands in 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 (3 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | Deep basin (29 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 2 to 15 ft | midday & dawn | Main-lake point (3 ft) | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Break off the point (17 ft) | Small jigging spoon, Tungsten jig + plastic |
When the water first warms, landlocked salmon slide up into 1 to 15 ft. By summer they slide out to 9 to 30 ft, and by winter most fish are in 8 to 30 ft. If you only fish one area, make it Deep basin: a deep basin around 29 ft that scores prime in summer. In summer the feeding windows fall in early morning and the evening. Keep a dodger + streamer down deep or a thin spoon on lead core rigged through the warm months.

| Printemps | 1 to 15 ft | dawn & dusk | Main-lake point (3 ft) | Streamer flies (Grey Ghost) off boards, Thin spoon (Mooselook style) |

The spring pattern is a shallow one: walleye in 4 to 15 ft. Midsummer fish sit out in 9 to 30 ft before dropping to 9 to 30 ft for winter. The spot to know is Break off the point, a drop-off in about 17 ft of water that rates prime for walleye in fall. Plan around the evening and early morning in the warm months. Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) gets it done.

|---|---|---|---|---|
| Printemps | 4 to 15 ft | dusk & dawn | Secondary point (6 ft) | 1/8 oz jig + minnow, Hair jig |

In spring, yellow perch run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 9 to 30 ft for winter. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Fish it in early morning and you'll meet the bite. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
