356-acre lake near Québec. The lake tops out around 16 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here is how the season plays out for each species, straight from the data behind the map.
Drawn out, this is 356 acres of water rimmed by 4.2 miles of bank. The shoreline is moderately structured (index 1.6) — enough points and pockets to pattern. The basin spans about 1.9 mi end to end and 0.5 mi across at its widest. You'll find it in La Haute-Yamaska MRC. The nearest mapped water is Lac Roxton, 5 mi to the northeast.

In spring, rainbow trout run shallow here, mostly 4 to 16 ft. Summer keeps them at 4 to 16 ft, and they winter in 3 to 16 ft. Break off the point is the standout, a drop-off at roughly 3 ft, rated prime for winter rainbow trout. Time it for early morning and the evening. You won't need more than a dodger + spoon (deep troll) or a flutter spoon most summer days.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 4 to 16 ft chart-limited; documented 5 to 20 ft | dawn & dusk | Main-lake point (2 ft) | Inline spinner (silver), Small spoon |
| Été | 4 to 16 ft chart-limited; documented 8 to 30 ft | dawn & dusk | Break off the point (3 ft) | Dodger + spoon (deep troll), Flutter spoon |

When the water first warms, brown trout slide up into 2 to 16 ft. There's no big seasonal slide here — summer means 5 to 16 ft, winter 2 to 16 ft. If you only fish one area, make it Deep basin: a deep basin around 11 ft that scores prime in summer. In summer the feeding windows fall in after dark and early morning. Keep a spoon at the thermocline or a deep stickbait (night) rigged through the warm months.

When the water first warms, walleye slide up into 4 to 15 ft. By summer they slide out to 5 to 16 ft, and by winter most fish are in 5 to 16 ft. If you only fish one area, make it Deep basin: a deep basin around 11 ft that scores prime in winter. In summer the feeding windows fall in the evening and early morning. Keep a crawler harness on bottom bouncer or a deep crankbait (trolled) rigged through the warm months.

When the water first warms, yellow perch slide up into 3 to 12 ft. Summer is a 5 to 16 ft game here, winter a 5 to 16 ft one. Start at Deep basin. It's a deep basin holding about 11 ft of water and rates prime come fall. The feeding windows run early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.

The spring pattern is a shallow one: northern pike in 2 to 8 ft. Midsummer fish sit out in 5 to 16 ft before dropping to 5 to 15 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 2 ft of water that rates prime for northern pike in spring. Plan around early morning and the evening in the warm months. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.

Anglers target rainbow trout, brown trout, walleye, yellow perch, northern pike, smallmouth bass, largemouth bass, rock bass, pumpkinseed, brown bullhead, common carp, chain pickerel on Lac Boivin. This species list is an informed estimate from Québec's provincial fish-range maps (bounded by each lake's depth and habitat), not a per-lake fish survey — Québec doesn't publish per-lake species records.
Deep basin is the top-rated area: a deep basin in about 11 ft of water that rates prime for walleye in winter. Scroll up to the map for the complete spot list by species and season.
For rainbow trout, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
