186-acre lake near Québec. The lake tops out around 25 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.
The drawn water covers 186 acres wrapped in 2.1 miles of bank. Its 1.1 shoreline index means few bank features; the contours below do the pattern work. 97% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Tip to tip the water measures near 0.9 mi with a 0.5-mi widest point. It sits in La Côte-de-Beaupré MRC. If the bite dies, Lac Grandpré is 1 mi to the north.

Early season brook trout use the shallows, holding in 2 to 15 ft. Expect a summer slide to 8 to 25 ft, then a winter hold in 3 to 20 ft. Put Deep basin first on the milk run — a deep basin near 24 ft that grades prime for summer. In summer the feeding windows fall in 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.

|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Shallow bay flat (2 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 8 to 25 ft | dawn & dusk | Deep basin (24 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |

The spring pattern is a shallow one: yellow perch in 3 to 12 ft. Midsummer fish sit out in 8 to 25 ft before dropping to 8 to 25 ft for winter. The spot to know is Back-bay flat, a weed flat in about 3 ft of water that rates prime for yellow perch in spring. Plan around early morning in the warm months. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
