29-acre lake near Québec. The lake tops out around 25 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here's the year, species by species, as the scoring engine sees it.
The drawn water covers 29 acres wrapped in 0.8 miles of bank. The basin is a simple one (shoreline index 1.1) — close to a bowl, so the structure on the chart matters more than the bank. About 64% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 0.3 mi long by 0.2 mi wide at the broadest reach. It sits in Papineau MRC. Its nearest charted neighbour, Lac Dumas, is 1 mi to the southeast.

Early season brook trout use the shallows, holding in 2 to 15 ft. Expect a summer slide to 8 to 25 ft, then a winter hold in 3 to 20 ft. Put Deep basin first on the milk run — a deep basin near 24 ft that grades prime for summer. In summer the feeding windows fall in early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.

Spring rainbow trout on Petit lac Saint-Denis hold shallow, usually 5 to 20 ft. By summer they slide out to 7 to 25 ft, and by winter most fish are in 5 to 25 ft. The chart's best answer is Deep basin — deep basin, 24 ft, prime for winter. Prime time lands in early morning and the evening. The summer box starts with a dodger + spoon (deep troll) or a flutter spoon.

In spring, brown trout run shallow here, mostly 3 to 25 ft. Summer keeps them at 8 to 25 ft, and they winter in 4 to 25 ft. Summer brown trout concentrate at Deep basin, a prime-rated deep basin around 24 ft. Fish it in after dark and early morning and you'll meet the bite. You won't need more than a spoon at the thermocline or a deep stickbait (night) most summer days.

Spring landlocked salmon on Petit lac Saint-Denis hold shallow, usually 1 to 15 ft. By summer they slide out to 8 to 25 ft, and by winter most fish are in 6 to 25 ft. The chart's best answer is Deep basin — deep basin, 24 ft, prime for summer. Prime time lands in early morning and the evening. The summer box starts with a dodger + streamer down deep or a thin spoon on lead core.

In spring, walleye run shallow here, mostly 4 to 15 ft. Midsummer fish sit out in 8 to 25 ft before dropping to 8 to 25 ft for winter. Winter walleye concentrate at Deep basin, a prime-rated deep basin around 24 ft. Fish it in the evening and early morning and you'll meet the bite. You won't need more than a crawler harness on bottom bouncer or a deep crankbait (trolled) most summer days.

The spring pattern is a shallow one: yellow perch in 3 to 12 ft. Midsummer fish sit out in 8 to 25 ft before dropping to 8 to 25 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 4 ft of water that rates prime for yellow perch in spring. Plan around early morning in the warm months. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
