520-acre lake near Québec. The lake tops out around 180 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. Below is the species-by-species picture, pulled from the same data the map uses.
The outline encloses 521 acres, worked by 4.1 miles of shoreline. A shoreline index of 1.3 says round and simple: fish relate to depth changes here, not shoreline features. 4% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. End to end it runs roughly 1.5 mi, about 1 mi across. Maskinongé MRC claims this one. If the bite dies, Lac l'Orignal is 1 mi to the north.

Spring brook trout on Lac au Sable hold shallow, usually 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. Put Main-lake point first on the milk run — a point near 15 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Main-lake point (15 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | open water | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 2 to 15 ft | midday & dawn | Main-lake point (15 ft) | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Shallow bay flat (10 ft) | Small jigging spoon, Tungsten jig + plastic |
Come spring, look for lake trout tight to the bank in 10 to 40 ft. They move out to 50 to 120 ft in summer and finish the year down in 20 to 80 ft. If you only fish one area, make it Main-lake point: a point around 15 ft that scores prime in spring. Best bite is early morning. A white tube jig (deep) or a magnum spoon on downrigger is the honest summer answer here.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 10 to 40 ft | dawn & dusk | Main-lake point (15 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Été | 50 to 120 ft | dawn | Break off the point (94 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Automne | 10 to 50 ft | dusk & dawn | Main-lake point (15 ft) | Heavy casting spoon, Jigging rap over reefs |
| Hiver | 20 to 80 ft | dawn | Break off the point (94 ft) | White tube jig, Airplane jig |
Early season landlocked salmon use the shallows, holding in 1 to 15 ft. Summer is a 25 to 60 ft game here, winter a 10 to 40 ft one. The chart's best answer is Main-lake point — point, 15 ft, prime for spring. Best bite is early morning and the evening. Tie on a dodger + streamer down deep or a thin spoon on lead core and you're in the game.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 1 to 15 ft | dawn & dusk | Main-lake point (15 ft) | Streamer flies (Grey Ghost) off boards, Thin spoon (Mooselook style) |

| Hiver | 10 to 40 ft | dawn | Main-lake point (15 ft) | Small jigging spoon, Swedish pimple + smelt |
The spring pattern is a shallow one: arctic char in 4 to 15 ft. Midsummer fish sit out in 20 to 60 ft before dropping to 10 to 40 ft for winter. The spot to know is Shallow bay flat, a feeding flat in about 10 ft of water that rates good for arctic char in spring. Plan around early morning in the warm months. Summer baits: a jigging spoon vertical or a tube jig (smelt) gets it done.

The spot to know is Break off the point, a drop-off in about 94 ft of water that rates prime for lake whitefish in summer. Plan around early morning in the warm months. Summer baits: a blade bait vertical or a small jigging spoon gets it done.

The spot to know is Deep basin, a deep basin in about 179 ft of water that rates good for cisco (lake herring) in spring. Plan around early morning in the warm months. Summer baits: a vertical flutter spoon (small) or a drop-shot micro plastic gets it done.
