77-acre lake near Québec. The lake tops out around 50 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:
On the chart, Lac du Rocher draws 77 acres inside 1.4 miles of shoreline. The basin is a simple one (shoreline index 1.2) — close to a bowl, so the structure on the chart matters more than the bank. The shallow band under 15 ft claims about 54% of the surface — that's where the groceries are. Tip to tip the water measures near 0.5 mi with a 0.4-mi widest point. The water lies in Mékinac MRC. The nearest mapped water is Lac Long, 1 mi to the west.

In spring, brook trout run shallow here, mostly 2 to 15 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 3 to 20 ft for winter. Summer brook trout concentrate at Break off the point, a prime-rated drop-off around 22 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.

|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Main-lake point (5 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | Break off the point (22 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |

Spring puts lake trout in skinny water — 10 to 40 ft is the zone. As the season builds they drop to 15 to 50 ft, wintering in 13 to 50 ft. Summer lake trout concentrate at Deep basin, a prime-rated deep basin around 50 ft. Warm-month bites cluster around early morning. A white tube jig (deep) or a magnum spoon on downrigger covers the summer program.

| Printemps | 10 to 40 ft | dawn & dusk | Break off the point (22 ft) | Casting spoon over shoals, Jerkbait (shallow) |

Early season lake whitefish use the shallows, holding in 15 to 45 ft. Expect a summer slide to 15 to 50 ft, then a winter hold in 15 to 50 ft. Put Deep basin first on the milk run — a deep basin near 50 ft that grades prime for summer. In summer the feeding windows fall in early morning. Tie on a blade bait vertical or a small jigging spoon and you're in the game.

Early season cisco (lake herring) use the shallows, holding in 10 to 40 ft. Expect a summer slide to 15 to 50 ft, then a winter hold in 15 to 50 ft. Put Deep basin first on the milk run — a deep basin near 50 ft that grades prime for summer. In summer the feeding windows fall in early morning. Tie on a vertical flutter spoon (small) or a drop-shot micro plastic and you're in the game.

Come spring, look for walleye tight to the bank in 4 to 15 ft. They move out to 15 to 35 ft in summer and finish the year down in 20 to 40 ft. If you only fish one area, make it Break off the point: a drop-off around 22 ft that scores prime in fall. Best bite is 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 (5 ft) | 1/8 oz jig + minnow, Hair jig |

Come spring, look for yellow perch tight to the bank in 3 to 12 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 15 to 35 ft. Start at Shallow bay flat. It's a weed flat holding about 4 ft of water and rates prime come spring. Prime time lands in early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.
