260-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. Species by species, here's what the data says the year looks like.
Traced from the shoreline, Lac Roger runs 260 acres with 2.8 miles of edge. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. The shallow band under 15 ft claims about 66% of the surface — that's where the groceries are. End to end it runs roughly 1 mi, about 0.6 mi across. The water lies in Le Saguenay-et-son-Fjord. Closest neighbour on DepthScout: Lac Laurent, 2 mi southeast of here.

Spring puts brook trout in skinny water — 2 to 15 ft is the zone. Warm water sends them out to 10 to 30 ft; cold water stacks them in 3 to 20 ft. Break off the point is the standout, a drop-off at roughly 16 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 (4 ft) | Small inline spinner (gold), Tiny spoon |

In spring, landlocked salmon run shallow here, mostly 1 to 15 ft. Midsummer fish sit out in 12 to 39 ft before dropping to 10 to 39 ft for winter. Summer landlocked salmon concentrate at Deep basin, a prime-rated deep basin around 36 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.

Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
