33-acre lake near Québec. The lake tops out around 26 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 season-by-season read for each species follows, from the map's own numbers.
Traced from the shoreline, Lac des Roches runs 33 acres with 1 miles of edge. At index 1.3 the outline is almost a bowl — read the depth changes, not the shoreline. The shallow band under 15 ft claims about 83% of the surface — that's where the groceries are. End to end it runs roughly 0.5 mi, about 0.2 mi across. You'll find it in Montcalm MRC. For a second option, Lac des Quatre Saisons lies 0 mi east.

Spring puts rainbow trout in skinny water — 5 to 20 ft is the zone. As the season builds they drop to 7 to 26 ft, wintering in 5 to 26 ft. Winter rainbow trout concentrate at Break off the point, a prime-rated drop-off around 9 ft. Warm-month bites cluster around early morning and the evening. 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 | Break off the point (9 ft) | Inline spinner (silver), Small spoon |
| Été | 7 to 26 ft | dawn & dusk | Break off the point (9 ft) | Dodger + spoon (deep troll), Flutter spoon |

| Hiver | 5 to 26 ft | dawn | Break off the point (9 ft) | Jigging spoon, Tube jig (white) |
Come spring, look for brown trout tight to the bank in 3 to 25 ft. Expect a summer slide to 8 to 26 ft, then a winter hold in 4 to 26 ft. Start at Break off the point. It's a drop-off holding about 9 ft of water and rates prime come summer. Prime time lands in after dark and early morning. A spoon at the thermocline or a deep stickbait (night) is the honest summer answer here.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 3 to 25 ft | dawn & dusk | Main-lake point (3 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |

| Hiver | 4 to 26 ft | dawn | Break off the point (9 ft) | Jigging spoon, Small stickbait (slow) |
Come spring, look for walleye tight to the bank in 4 to 15 ft. Expect a summer slide to 8 to 26 ft, then a winter hold in 8 to 26 ft. Start at Break off the point. It's a drop-off holding about 9 ft of water and rates prime come fall. Prime time lands in the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) is the honest summer answer here.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 4 to 15 ft | dusk & dawn | Main-lake point (3 ft) | 1/8 oz jig + minnow, Hair jig |

| Hiver | 8 to 26 ft | dusk & dawn | Deep basin (26 ft) | Jigging spoon + minnow head, Rattle bait |
Come spring, look for yellow perch tight to the bank in 3 to 12 ft. They move out to 8 to 26 ft in summer and finish the year down in 8 to 26 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. Best bite is 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 | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |

Start shallow in spring: northern pike sit in 2 to 8 ft that time of year. Warm water sends them out to 8 to 20 ft; cold water stacks them in 5 to 15 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a bucktail or a weedless spoon over cabbage until the fish tell you otherwise.
