195-acre lake near Québec. The lake tops out around 59 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's the year, species by species, as the scoring engine sees it.
The outline encloses 195 acres, worked by 2.3 miles of shoreline. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. Littoral water — the productive band under ~15 ft — makes up 33% of this chart. Tip to tip the water measures near 0.9 mi with a 0.5-mi widest point. Le Val-Saint-François MRC claims this one. Its nearest charted neighbour, Lac Desmarais, is 1 mi to the northwest.

Come spring, look for lake trout tight to the bank in 10 to 40 ft. They move out to 18 to 59 ft in summer and finish the year down in 15 to 59 ft. If you only fish one area, make it Deep basin: a deep basin around 59 ft that scores prime in summer. Best bite is early morning. A white tube jig (deep) or a magnum spoon on downrigger is the honest summer answer here.

|---|---|---|---|---|
| Printemps | 10 to 40 ft | dawn & dusk | Break off the point (32 ft) | Casting spoon over shoals, Jerkbait (shallow) |

Tie on a dodger + spoon (deep troll) or a flutter spoon and you're in the game.
