5,833-acre lake near Québec. The lake tops out around 100 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 Jean-Peré draws 5,832 acres inside 44 miles of shoreline. A development index of 4.1 means a maze of bays and points: far more casting targets than a round bowl of the same size. Roughly 53% of the water is 15 ft or less, the band where the food chain lives. End to end it runs roughly 9.4 mi, about 4.9 mi across. You'll find it in La Vallée-de-la-Gatineau MRC. For a second option, Lac Fabrezan lies 4 mi north.

Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 3 to 20 ft. The spot to know is Main-lake point, a point in about 13 ft of water that rates prime for brook trout in spring. Warm-month bites cluster around early morning and the evening. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.
| 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 | Break off the point (8 ft) | 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 | Break off the point (8 ft) | Small jigging spoon, Tungsten jig + plastic |
Start shallow in spring: lake trout sit in 10 to 40 ft that time of year. Warm water sends them out to 30 to 100 ft; cold water stacks them in 20 to 80 ft. Top water on the chart: Deep basin, a deep basin in the 85 ft range, prime in summer. Fish it in early morning and you'll meet the bite. Throw a white tube jig (deep) or a magnum spoon on downrigger until the fish tell you otherwise.

When the water first warms, lake whitefish slide up into 15 to 45 ft. Summer is a 40 to 90 ft game here, winter a 25 to 70 ft one. Start at Deep basin. It's a deep basin holding about 85 ft of water and rates prime come summer. The feeding windows run early morning. Keep a blade bait vertical or a small jigging spoon rigged through the warm months.

It's a deep basin holding about 85 ft of water and rates prime come summer. The feeding windows run early morning. Keep a vertical flutter spoon (small) or a drop-shot micro plastic rigged through the warm months.

Early season walleye use the shallows, holding in 4 to 15 ft. Expect a summer slide to 15 to 35 ft, then a winter hold in 20 to 40 ft. Put Sharp break first on the milk run — a drop-off near 41 ft that grades prime for fall. In summer the feeding windows fall in the evening and early morning. Tie on a crawler harness on bottom bouncer or a deep crankbait (trolled) and you're in the game.

Keep a bottom bouncer + crawler or a 3-way rig with stickbait rigged through the warm months.
