19-acre lake near Québec. The lake tops out around 39 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's the year, species by species, as the scoring engine sees it.
On the chart, Petit lac Rainbow draws 19 acres inside 0.7 miles of shoreline. At index 1.1 the outline is almost a bowl — read the depth changes, not the shoreline.

Spring puts rainbow trout in skinny water — 5 to 20 ft is the zone. Warm water sends them out to 8 to 30 ft; cold water stacks them in 8 to 39 ft. Break off the point is the standout, a drop-off at roughly 31 ft, rated prime for winter rainbow trout. Plan around early morning and the evening in the warm months. A dodger + spoon (deep troll) or a flutter spoon covers the summer program.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 5 to 20 ft | dawn & dusk | Main-lake point (19 ft) | Inline spinner (silver), Small spoon |

Come spring, look for brown trout tight to the bank in 3 to 25 ft. They move out to 12 to 39 ft in summer and finish the year down in 5 to 35 ft. If you only fish one area, make it Break off the point: a drop-off around 31 ft that scores prime in summer. Best bite is after dark and early morning. A spoon at the thermocline or a deep stickbait (night) is the honest summer answer here.

Come spring, look for walleye tight to the bank in 4 to 15 ft. They move out to 15 to 35 ft in summer and finish the year down in 12 to 39 ft. If you only fish one area, make it Break off the point: a drop-off around 31 ft that scores prime in fall. Best bite is the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) is the honest summer answer here.

Come spring, look for yellow perch tight to the bank in 3 to 12 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 15 to 35 ft. Start at Break off the point. It's a drop-off holding about 31 ft of water and rates prime come fall. Prime time lands in early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.

| Printemps | 3 to 12 ft | midday & dawn | open water | Small jig + curly tail, Perch-pattern micro crank |

Start shallow in spring: northern pike sit in 2 to 8 ft that time of year. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 5 to 15 ft. The spot to know is Main-lake point, a point in about 19 ft of water that rates prime for northern pike in summer. Warm-month bites cluster around early morning and the evening. Throw a bucktail or a weedless spoon over cabbage until the fish tell you otherwise.

Break off the point is the standout, a drop-off at roughly 31 ft, rated prime for fall muskellunge. Time it for the evening and early morning. You won't need more than a double-10 bucktail or a topwater (walk-the-dog / creeper) most summer days.
