76-acre lake near Québec. The lake tops out around 39 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. The rest of this page walks each species through its year, using the map's own scoring.
Traced from the shoreline, Lac Boisvert runs 76 acres with 1.5 miles of edge. At index 1.2 the outline is almost a bowl — read the depth changes, not the shoreline. 57% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. End to end it runs roughly 0.6 mi, about 0.3 mi across. The water lies in Matawinie MRC. For a second option, Lac à Régnières lies 2 mi southeast.

Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Warm water sends them out to 10 to 30 ft; cold water stacks them in 3 to 20 ft. Top water on the chart: Break off the point, a drop-off in the 22 ft range, prime in summer. Fish it in early morning and the evening and you'll meet the bite. 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 |

The spring pattern is a shallow one: landlocked salmon in 1 to 15 ft. Midsummer fish sit out in 12 to 39 ft before dropping to 10 to 39 ft for winter. The spot to know is Deep basin, a deep basin in about 39 ft of water that rates prime for landlocked salmon in summer. Plan around early morning and the evening in the warm months. Summer baits: a dodger + streamer down deep or a thin spoon on lead core gets it done.

The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.

Spring northern pike concentrate at Shallow bay flat, a prime-rated weed flat around 4 ft. Warm-month bites cluster around early morning and the evening. A bucktail or a weedless spoon over cabbage covers the summer program.
