327-acre lake near Québec. The lake tops out around 20 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.
On the chart, Lac Prime draws 327 acres inside 4.8 miles of shoreline. The shoreline is moderately structured (index 1.9) — enough points and pockets to pattern. The shallow band under 15 ft claims about 95% of the surface — that's where the groceries are. End to end it runs roughly 2.1 mi, about 0.5 mi across. The water lies in Rimouski-Neigette MRC. The nearest mapped water is Lac Huron, 1 mi to the south.

Spring puts brook trout in skinny water — 2 to 15 ft is the zone. Warm water sends them out to 6 to 20 ft; cold water stacks them in 3 to 20 ft. Deep basin is the standout, a deep basin at roughly 19 ft, rated prime for summer brook trout. Plan around early morning and the evening in the warm months. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.

|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Main-lake point (2 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 6 to 20 ft | dawn & dusk | Deep basin (19 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |

| Hiver | 3 to 20 ft | dawn | Deep basin (19 ft) | Small jigging spoon, Tungsten jig + plastic |
In spring, landlocked salmon run shallow here, mostly 1 to 15 ft. Midsummer fish sit out in 6 to 20 ft before dropping to 5 to 20 ft for winter. Summer landlocked salmon concentrate at Deep basin, a prime-rated deep basin around 19 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a dodger + streamer down deep or a thin spoon on lead core most summer days.

|---|---|---|---|---|
| Printemps | 1 to 15 ft | dawn & dusk | Main-lake point (2 ft) | Streamer flies (Grey Ghost) off boards, Thin spoon (Mooselook style) |

When the water first warms, yellow perch slide up into 3 to 12 ft. By summer they slide out to 6 to 20 ft, and by winter most fish are in 6 to 20 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 4 ft that scores prime in spring. In summer the feeding windows fall in early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.

| Printemps | 3 to 12 ft | midday & dawn | Shallow bay flat (4 ft) | Small jig + curly tail, Perch-pattern micro crank |
