645-acre lake near Québec. The lake tops out around 131 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 is how the season plays out for each species, straight from the data behind the map.
Drawn out, this is 645 acres of water rimmed by 7.5 miles of bank. Index 2.1 on the shoreline: a few honest points and pockets, nothing labyrinthine. Roughly 14% of the water is 15 ft or less, the band where the food chain lives. End to end it runs roughly 3.2 mi, about 0.9 mi across. The water lies in Antoine-Labelle MRC. The nearest mapped water is Baie Nadon, 2 mi to the south.

The spring pattern is a shallow one: brook trout in 2 to 15 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 3 to 20 ft for winter. The spot to know is Main-lake point, a point in about 13 ft of water that rates prime for brook trout in spring. Plan around early morning and the evening in the warm months. Summer baits: a small spoon fished deep or a trolled lake-clear wobbler + worm gets it done.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Main-lake point (13 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 (13 ft) | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Shallow bay flat (10 ft) | Small jigging spoon, Tungsten jig + plastic |
The spring pattern is a shallow one: lake trout in 10 to 40 ft. As the season builds they drop to 50 to 120 ft, wintering in 20 to 80 ft. Top water on the chart: Deep basin, a deep basin in the 119 ft range, prime in summer. Time it for early morning. Summer baits: a white tube jig (deep) or a magnum spoon on downrigger gets it done.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 10 to 40 ft | dawn & dusk | Main-lake point (13 ft) | Casting spoon over shoals, Jerkbait (shallow) |

| Hiver | 20 to 80 ft | dawn | Break off the point (44 ft) | White tube jig, Airplane jig |
Come spring, look for lake whitefish tight to the bank in 15 to 45 ft. Expect a summer slide to 40 to 90 ft, then a winter hold in 25 to 70 ft. Start at Break off the point. It's a drop-off holding about 44 ft of water and rates prime come spring. Prime time lands in early morning. A blade bait vertical or a small jigging spoon is the honest summer answer here.

Come spring, look for cisco (lake herring) tight to the bank in 10 to 40 ft. Expect a summer slide to 40 to 80 ft, then a winter hold in 20 to 60 ft. Start at Break off the point. It's a drop-off holding about 44 ft of water and rates prime come winter. Prime time lands in early morning. A vertical flutter spoon (small) or a drop-shot micro plastic is the honest summer answer here.

Spring walleye on Lac Rochon hold shallow, usually 4 to 15 ft. They move out to 15 to 35 ft in summer and finish the year down in 20 to 40 ft. Put Main-lake point first on the milk run — a point near 13 ft that grades prime for fall. The feeding windows run the evening and early morning. The summer box starts with a crawler harness on bottom bouncer or a deep crankbait (trolled).

| Printemps | 4 to 15 ft | dusk & dawn | Main-lake point (13 ft) | 1/8 oz jig + minnow, Hair jig |

Early season yellow perch use the shallows, holding in 3 to 12 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 15 to 35 ft.

Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.
