20-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 20 acres, worked by 0.6 miles of shoreline. A shoreline index of 1 says round and simple: fish relate to depth changes here, not shoreline features. The shallow band under 15 ft claims about 22% of the surface — that's where the groceries are. Maskinongé MRC claims this one. If the bite dies, Lac Traverse is 0 mi to the northwest.

When the water first warms, brook trout slide up into 2 to 15 ft. Summer is a 10 to 30 ft game here, winter a 3 to 20 ft one. Start at Shoreline break. It's a drop-off holding about 26 ft of water and rates prime come summer. The feeding windows run early morning and the evening. Keep a small spoon fished deep or a trolled lake-clear wobbler + worm rigged through the warm months.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Shallow bay flat (15 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | Shoreline break (26 ft) | 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 (15 ft) | Small jigging spoon, Tungsten jig + plastic |
Early season lake trout use the shallows, holding in 10 to 40 ft. Summer is a 16 to 53 ft game here, winter a 13 to 53 ft one. The chart's best answer is Deep basin — deep basin, 52 ft, prime for summer. Best bite is early morning. Tie on a white tube jig (deep) or a magnum spoon on downrigger and you're in the game.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 10 to 40 ft | dawn & dusk | Shoreline break (26 ft) | Casting spoon over shoals, Jerkbait (shallow) |

Come spring, look for landlocked salmon tight to the bank in 1 to 15 ft. They move out to 16 to 53 ft in summer and finish the year down in 10 to 40 ft. If you only fish one area, make it Deep basin: a deep basin around 52 ft that scores prime in summer. Best bite is early morning and the evening. A dodger + streamer down deep or a thin spoon on lead core is the honest summer answer here.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 1 to 15 ft | dawn & dusk | open water | Streamer flies (Grey Ghost) off boards, Thin spoon (Mooselook style) |
