31-acre lake near Québec. The lake tops out around 35 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. Every species below gets its seasonal read from the same numbers driving the chart.
Traced from the shoreline, Lac Osborn runs 31 acres with 1 miles of edge. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. Roughly 51% of the water is 15 ft or less, the band where the food chain lives. Figure 0.4 mi of water from one end to the other, 0.2 mi at the beam. The water lies in Maskinongé MRC. For a second option, Lac Traverse lies 1 mi east.

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: Shoreline break, a drop-off in the 4 ft range, prime in winter. 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 | Shallow bay flat (7 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 11 to 35 ft before dropping to 9 to 35 ft for winter. The spot to know is Deep basin, a deep basin in about 35 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.
