3,204-acre lake near Québec. The lake tops out around 148 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 Tourbis maps at 3,204 acres behind 20.7 miles of shoreline. A development index of 2.6 means a maze of bays and points: far more casting targets than a round bowl of the same size. 13% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Call it 5.4 mi long by 3.1 mi wide at the broadest reach. It sits in Matawinie MRC. Lac Hastel sits 14 mi south — the closest neighbouring chart.

Spring brook trout on Lac Tourbis hold shallow, usually 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. The chart's best answer is Break off the point — drop-off, 27 ft, prime for summer. Prime time lands in early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Main-lake point (9 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | Break off the point (27 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 2 to 15 ft | midday & dawn | Main-lake point (9 ft) | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Shallow bay flat (10 ft) | Small jigging spoon, Tungsten jig + plastic |
Come spring, look for lake trout tight to the bank in 10 to 40 ft. Expect a summer slide to 50 to 120 ft, then a winter hold in 20 to 80 ft. Start at Rock reef. It's a rock pile holding about 9 ft of water and rates prime come fall. Prime time lands in early morning. A white tube jig (deep) or a magnum spoon on downrigger is the honest summer answer here.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 10 to 40 ft | dawn & dusk | Secondary point (17 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Été | 50 to 120 ft | dawn | Deep basin (144 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Automne | 10 to 50 ft | dusk & dawn | Rock reef (9 ft) | Heavy casting spoon, Jigging rap over reefs |
| Hiver | 20 to 80 ft | dawn | Break off the point (27 ft) | White tube jig, Airplane jig |
The spring pattern is a shallow one: lake whitefish in 15 to 45 ft. As the season builds they drop to 40 to 90 ft, wintering in 25 to 70 ft. Top water on the chart: Rock reef, a rock pile in the 8 ft range, prime in fall. Time it for early morning. Summer baits: a blade bait vertical or a small jigging spoon gets it done.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 15 to 45 ft | midday & dawn | Break off the point (27 ft) | Small jig + waxworm, Blade bait (small) |

| Hiver | 25 to 70 ft | midday & dawn | Break off the point (27 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
The spring pattern is a shallow one: cisco (lake herring) in 10 to 40 ft. As the season builds they drop to 40 to 80 ft, wintering in 20 to 60 ft. Top water on the chart: Rock reef, a rock pile in the 8 ft range, prime in fall. Time it for early morning. Summer baits: a vertical flutter spoon (small) or a drop-shot micro plastic gets it done.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 10 to 40 ft | dawn & dusk | Break off the point (27 ft) | Small silver spoon, Tiny swim jig (white) |

Spring puts walleye in skinny water — 4 to 15 ft is the zone. Warm water sends them out to 15 to 35 ft; cold water stacks them in 20 to 40 ft. Break off the point is the standout, a drop-off at roughly 27 ft, rated prime for fall walleye. Plan around the evening and early morning in the warm months. A crawler harness on bottom bouncer or a deep crankbait (trolled) covers the summer program.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 4 to 15 ft | dusk & dawn | Rock reef (8 ft) | 1/8 oz jig + minnow, Hair jig |

Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Warm water sends them out to 10 to 30 ft; cold water stacks them in 15 to 35 ft. Top water on the chart: Break off the point, a drop-off in the 27 ft range, prime in summer. Fish it in early morning and you'll meet the bite. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.
