230-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. The rest of this page walks each species through its year, using the map's own scoring.
Petit lac Saint-François maps at 230 acres behind 2.5 miles of shoreline. At index 1.2 the outline is almost a bowl — read the depth changes, not the shoreline. Littoral water — the productive band under ~15 ft — makes up 17% of this chart. Call it 1 mi long by 0.5 mi wide at the broadest reach. It sits in Les Appalaches MRC. Its nearest charted neighbour, Lac Bécancour, is 6 mi to the north.

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 Main-lake point. It's a point holding about 7 ft of water and rates prime come spring. 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 (7 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 (7 ft) | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Shallow bay flat (5 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring lake trout on Petit lac Saint-François hold shallow, usually 10 to 40 ft. By summer they slide out to 16 to 53 ft, and by winter most fish are in 13 to 53 ft. The chart's best answer is Deep basin — deep basin, 53 ft, prime for summer. Prime time lands in early morning. The summer box starts with a white tube jig (deep) or a magnum spoon on downrigger.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 10 to 40 ft | dawn & dusk | Secondary point (8 ft) | Casting spoon over shoals, Jerkbait (shallow) |

When the water first warms, rainbow trout slide up into 5 to 20 ft. By summer they slide out to 8 to 30 ft, and by winter most fish are in 8 to 40 ft. If you only fish one area, make it Main-lake point: a point around 7 ft that scores prime in spring. In summer the feeding windows fall in 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 |
|---|---|---|---|---|
| Printemps | 5 to 20 ft | dawn & dusk | Main-lake point (7 ft) | Inline spinner (silver), Small spoon |

| Hiver | 8 to 40 ft | dawn | Break off the point (50 ft) | Jigging spoon, Tube jig (white) |
The spring pattern is a shallow one: brown trout in 3 to 25 ft. Midsummer fish sit out in 16 to 53 ft before dropping to 5 to 35 ft for winter. The spot to know is Break off the point, a drop-off in about 50 ft of water that rates prime for brown trout in summer. Plan around after dark and early morning in the warm months. Summer baits: a spoon at the thermocline or a deep stickbait (night) gets it done.

| Printemps | 3 to 25 ft | dawn & dusk | Main-lake point (7 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |

When the water first warms, landlocked salmon slide up into 1 to 15 ft. By summer they slide out to 16 to 53 ft, and by winter most fish are in 10 to 40 ft. If you only fish one area, make it Deep basin: a deep basin around 53 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.
