30-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. The season-by-season read for each species follows, from the map's own numbers.
Drawn out, this is 30 acres of water rimmed by 0.9 miles of bank. At index 1.2 the outline is almost a bowl — read the depth changes, not the shoreline. About 68% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Tip to tip the water measures near 0.4 mi with a 0.2-mi widest point. You'll find it in La Rivière-du-Nord MRC. Closest neighbour on DepthScout: Lac Croche, 1 mi west of here.

Spring puts rainbow trout in skinny water — 5 to 20 ft is the zone. As the season builds they drop to 8 to 30 ft, wintering in 6 to 30 ft. Winter rainbow trout concentrate at Break off the point, a prime-rated drop-off around 4 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 | Secondary point (11 ft) | Inline spinner (silver), Small spoon |
| Été | 8 to 30 ft | dawn & dusk | Secondary point (11 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Automne | 9 to 30 ft | dawn & dusk | Secondary point (11 ft) | Casting spoon, Jerkbait over shoals |
| Hiver | 6 to 30 ft | dawn | Break off the point (4 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 9 to 30 ft, then a winter hold in 4 to 30 ft. Start at Deep basin. It's a deep basin holding about 30 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.

| 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 30 ft | dawn | Break off the point (4 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 9 to 30 ft, then a winter hold in 9 to 30 ft. Start at Deep basin. It's a deep basin holding about 30 ft of water and rates prime come winter. 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 | Secondary point (11 ft) | 1/8 oz jig + minnow, Hair jig |

Come spring, look for yellow perch tight to the bank in 3 to 12 ft. They move out to 10 to 30 ft in summer and finish the year down in 9 to 30 ft. If you only fish one area, make it Deep basin: a deep basin around 30 ft that scores prime in fall. 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 | open water | Small jig + curly tail, Perch-pattern micro crank |

| Hiver | 9 to 30 ft | midday & dawn | Deep basin (30 ft) | Tungsten jig + spikes, Rattle spoon (small) |
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: Secondary point, a point in the 11 ft range, prime in fall. 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.
