14-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.
Petit lac Plat maps at 14 acres behind 0.6 miles of shoreline. At index 1.1 the outline is almost a bowl — read the depth changes, not the shoreline. 33% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. It sits in Antoine-Labelle MRC.

When the water first warms, brook trout slide up into 2 to 15 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 3 to 20 ft. If you only fish one area, make it Deep basin: a deep basin around 30 ft that scores prime in summer. In summer the feeding windows fall in 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 (9 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | Deep basin (30 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 (15 ft) | Small jigging spoon, Tungsten jig + plastic |
Come spring, look for rainbow trout tight to the bank in 5 to 20 ft. Expect a summer slide to 8 to 30 ft, then a winter hold in 6 to 30 ft. Start at Shoreline break. It's a drop-off holding about 15 ft of water and rates prime come winter. Prime time lands in early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon is the honest summer answer here.

Start shallow in spring: brown trout sit in 3 to 25 ft that time of year. Warm water sends them out to 9 to 30 ft; cold water stacks them in 4 to 30 ft. Top water on the chart: Shoreline break, a drop-off in the 15 ft range, prime in summer. Fish it in after dark and early morning and you'll meet the bite. Throw a spoon at the thermocline or a deep stickbait (night) until the fish tell you otherwise.

It's a deep basin holding about 30 ft of water and rates prime come summer. Prime time lands in early morning and the evening. A dodger + streamer down deep or a thin spoon on lead core is the honest summer answer here.

Top water on the chart: Shoreline break, a drop-off in the 15 ft range, prime in fall. Fish it in the evening and early morning and you'll meet the bite. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.
