333-acre lake near Québec. The lake tops out around 80 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. What the data behind the map says about each species, season by season:
The drawn water covers 333 acres wrapped in 3.5 miles of bank. The basin is a simple one (shoreline index 1.4) — close to a bowl, so the structure on the chart matters more than the bank. 19% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Call it 1.1 mi long by 0.9 mi wide at the broadest reach. It sits in Pontiac MRC. If the bite dies, Lac Wisopchidick is 2 mi to the north.

Early season brook trout use the shallows, holding in 2 to 15 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 3 to 20 ft. Put Main-lake point first on the milk run — a point near 10 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Main-lake point (10 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | open water | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 2 to 15 ft | midday & dawn | Main-lake point (10 ft) | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Shallow bay flat (6 ft) | Small jigging spoon, Tungsten jig + plastic |
When the water first warms, lake trout slide up into 10 to 40 ft. By summer they slide out to 24 to 80 ft, and by winter most fish are in 20 to 80 ft. If you only fish one area, make it Deep basin: a deep basin around 80 ft that scores prime in summer. In summer the feeding windows fall in early morning. Keep a white tube jig (deep) or a magnum spoon on downrigger rigged through the warm months.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 10 to 40 ft | dawn & dusk | Main-lake point (10 ft) | Casting spoon over shoals, Jerkbait (shallow) |

Start shallow in spring: lake whitefish sit in 15 to 45 ft that time of year. Summer pushes them deeper, 24 to 80 ft, and winter fish settle into 25 to 70 ft. The spot to know is Deep basin, a deep basin in about 80 ft of water that rates prime for lake whitefish in summer. Warm-month bites cluster around early morning. Throw a blade bait vertical or a small jigging spoon until the fish tell you otherwise.

|---|---|---|---|---|
| Printemps | 15 to 45 ft | midday & dawn | Break off the point (41 ft) | Small jig + waxworm, Blade bait (small) |

| Hiver | 25 to 70 ft | midday & dawn | Break off the point (41 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Start shallow in spring: cisco (lake herring) sit in 10 to 40 ft that time of year. Summer pushes them deeper, 40 to 80 ft, and winter fish settle into 20 to 60 ft. The spot to know is Deep basin, a deep basin in about 80 ft of water that rates prime for cisco (lake herring) in summer. Warm-month bites cluster around early morning. Throw a vertical flutter spoon (small) or a drop-shot micro plastic until the fish tell you otherwise.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |

| Printemps | 10 to 40 ft | dawn & dusk | Break off the point (41 ft) | Small silver spoon, Tiny swim jig (white) |

| Hiver | 20 to 60 ft | dawn | Break off the point (41 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
In spring, walleye run shallow here, mostly 4 to 15 ft. Midsummer fish sit out in 15 to 35 ft before dropping to 20 to 40 ft for winter. Fall walleye concentrate at Break off the point, a prime-rated drop-off around 41 ft. Fish it in the evening and early morning and you'll meet the bite. You won't need more than a crawler harness on bottom bouncer or a deep crankbait (trolled) most summer days.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 4 to 15 ft | dusk & dawn | Main-lake point (10 ft) | 1/8 oz jig + minnow, Hair jig |

| Hiver | 20 to 40 ft | dusk & dawn | Break off the point (41 ft) | Jigging spoon + minnow head, Rattle bait |
Spring puts sauger in skinny water — 4 to 18 ft is the zone. As the season builds they drop to 10 to 30 ft, wintering in 15 to 45 ft. Winter sauger concentrate at Break off the point, a prime-rated drop-off around 41 ft. Warm-month bites cluster around early morning and the evening. A bottom bouncer + crawler or a 3-way rig with stickbait covers the summer program.
