703-acre lake near Québec. The lake tops out around 79 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. Every species below gets its seasonal read from the same numbers driving the chart.
Lac Jérôme maps at 703 acres behind 6 miles of shoreline. With a 1.6 development index there's bank structure worth casting at, in moderation. The shallow band under 15 ft claims about 60% of the surface — that's where the groceries are. Call it 2.6 mi long by 0.8 mi wide at the broadest reach. Matawinie MRC claims this one. Its nearest charted neighbour, Lac Guénard, is 4 mi to the south.

Early season brook trout use the shallows, holding in 2 to 15 ft. Summer is a 10 to 30 ft game here, winter a 3 to 20 ft one. The chart's best answer is Break off the point — drop-off, 11 ft, prime for summer. Best bite is 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 (4 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | Break off the point (11 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |

When the water first warms, lake trout slide up into 10 to 40 ft. Summer is a 24 to 79 ft game here, winter a 20 to 79 ft one. Start at Deep basin. It's a deep basin holding about 71 ft of water and rates prime come summer. The feeding windows run early morning. Keep a white tube jig (deep) or a magnum spoon on downrigger rigged through the warm months.

Start shallow in spring: lake whitefish sit in 15 to 45 ft that time of year. Warm water sends them out to 24 to 79 ft; cold water stacks them in 25 to 70 ft. Top water on the chart: Deep basin, a deep basin in the 71 ft range, prime in summer. Fish it in early morning and you'll meet the bite. Throw a blade bait vertical or a small jigging spoon until the fish tell you otherwise.

Top water on the chart: Deep basin, a deep basin in the 71 ft range, prime in summer. Fish it in early morning and you'll meet the bite. Throw a vertical flutter spoon (small) or a drop-shot micro plastic until the fish tell you otherwise.

Break off the point is the standout, a drop-off at roughly 11 ft, rated prime for fall walleye. Time it for the evening and early morning. You won't need more than a crawler harness on bottom bouncer or a deep crankbait (trolled) most summer days.
