16-acre lake near Québec. The lake tops out around 23 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.
Lac Petit maps at 16 acres behind 0.7 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 67% of this chart. Tip to tip the water measures near 0.3 mi with a 0.2-mi widest point. Maskinongé MRC claims this one. If the bite dies, Lac Moyen is 1 mi to the south.

When the water first warms, brook trout slide up into 2 to 15 ft. Summer is a 7 to 23 ft game here, winter a 3 to 20 ft one. Start at Deep basin. It's a deep basin holding about 23 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 (3 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 7 to 23 ft | dawn & dusk | Deep basin (23 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 | Shoreline break (7 ft) | Small jigging spoon, Tungsten jig + plastic |
Come spring, look for landlocked salmon tight to the bank in 1 to 15 ft. They move out to 7 to 23 ft in summer and finish the year down in 6 to 23 ft. If you only fish one area, make it Deep basin: a deep basin around 23 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 | Shoreline break (7 ft) | Streamer flies (Grey Ghost) off boards, Thin spoon (Mooselook style) |
| Été | 7 to 23 ft | dawn & dusk | Deep basin (23 ft) | Dodger + streamer down deep, Thin spoon on lead core |
| Automne | 4 to 23 ft | dawn & dusk | Shoreline break (7 ft) | Casting spoon at the mouths, Streamers |
| Hiver | 6 to 23 ft | dawn | Deep basin (23 ft) | Small jigging spoon, Swedish pimple + smelt |
Start shallow in spring: walleye sit in 4 to 15 ft that time of year. Summer pushes them deeper, 7 to 23 ft, and winter fish settle into 7 to 23 ft. The spot to know is Shoreline break, a drop-off in about 7 ft of water that rates prime for walleye in fall. Warm-month bites cluster around the evening and early morning. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 4 to 15 ft | dusk & dawn | Shoreline break (7 ft) | 1/8 oz jig + minnow, Hair jig |
| Été | 7 to 23 ft | dusk & dawn | Shoreline break (7 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Automne | 7 to 23 ft | dusk & night | Shoreline break (7 ft) | Jigging rap, Jig + big minnow |
| Hiver | 7 to 23 ft | dusk & dawn | Deep basin (23 ft) | Jigging spoon + minnow head, Rattle bait |
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 7 to 23 ft, wintering in 7 to 23 ft. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Warm-month bites cluster around early morning. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Été | 7 to 23 ft | dawn | Deep basin (23 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Automne | 7 to 23 ft | midday | Deep basin (23 ft) | Jigging spoon (small), Perch rig / spreader |
| Hiver | 7 to 23 ft | midday & dawn | Deep basin (23 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring northern pike on Lac Petit hold shallow, usually 2 to 8 ft. By summer they slide out to 8 to 20 ft, and by winter most fish are in 5 to 15 ft. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Prime time lands in early morning and the evening. The summer box starts with a bucktail or a weedless spoon over cabbage.

|---|---|---|---|---|
| Printemps | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
