199-acre lake near Québec. The lake tops out around 85 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.
On the chart, Lac Poulin draws 199 acres inside 2.2 miles of shoreline. At index 1.1 the outline is almost a bowl — read the depth changes, not the shoreline. The shallow band under 15 ft claims about 34% of the surface — that's where the groceries are. Call it 0.8 mi long by 0.7 mi wide at the broadest reach. You'll find it in Beauce-Sartigan MRC. The nearest mapped water is Lac Raquette, 1 mi to the northeast.

In spring, brook trout run shallow here, mostly 2 to 15 ft. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 3 to 20 ft. Break off the point is the standout, a drop-off at roughly 15 ft, rated prime for summer brook trout. Time it for early morning and the evening. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.

Spring puts lake trout in skinny water — 10 to 40 ft is the zone. Warm water sends them out to 26 to 85 ft; cold water stacks them in 20 to 80 ft. Deep basin is the standout, a deep basin at roughly 84 ft, rated prime for summer lake trout. Plan around early morning in the warm months. A white tube jig (deep) or a magnum spoon on downrigger covers the summer program.

Spring puts rainbow trout in skinny water — 5 to 20 ft is the zone. As the season builds they drop to 8 to 30 ft, wintering in 8 to 40 ft. Winter rainbow trout concentrate at Break off the point, a prime-rated drop-off around 15 ft. Warm-month bites cluster around early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon covers the summer program.

Early season lake whitefish use the shallows, holding in 15 to 45 ft. Summer is a 26 to 85 ft game here, winter a 25 to 70 ft one. The chart's best answer is Deep basin — deep basin, 84 ft, prime for summer. Best bite is early morning. Tie on a blade bait vertical or a small jigging spoon and you're in the game.

The chart's best answer is Deep basin — deep basin, 84 ft, prime for summer. Best bite is 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. Expect a summer slide to 15 to 35 ft, then a winter hold in 20 to 40 ft. Start at Break off the point. It's a drop-off holding about 15 ft of water and rates prime come fall. Prime time lands in the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) is the honest summer answer here.

|---|---|---|---|---|
| Printemps | 4 to 15 ft | dusk & dawn | Main-lake point (5 ft) | 1/8 oz jig + minnow, Hair jig |
