551-acre lake near Québec. The lake tops out around 53 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.
On the chart, Lac Sainte-Marie draws 551 acres inside 4.7 miles of shoreline. Its 1.4 shoreline index means few bank features; the contours below do the pattern work. Littoral water — the productive band under ~15 ft — makes up 53% of this chart. Call it 2 mi long by 0.8 mi wide at the broadest reach. The water lies in Les Pays-d'en-Haut MRC. Closest neighbour on DepthScout: Lac de la Cabane, 1 mi north of here.

The spring pattern is a shallow one: lake trout in 10 to 40 ft. As the season builds they drop to 16 to 53 ft, wintering in 13 to 53 ft. Top water on the chart: Deep basin, a deep basin in the 52 ft range, prime in summer. Time it for early morning. Summer baits: a white tube jig (deep) or a magnum spoon on downrigger gets it done.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 10 to 40 ft | dawn & dusk | Main-lake point (10 ft) | Casting spoon over shoals, Jerkbait (shallow) |

| Automne | 10 to 50 ft | dusk & dawn | Main-lake point (10 ft) | Heavy casting spoon, Jigging rap over reefs |
| Hiver | 13 to 53 ft | dawn | Deep basin (52 ft) | White tube jig, Airplane jig |
Start shallow in spring: rainbow trout sit in 5 to 20 ft that time of year. Warm water sends them out to 8 to 30 ft; cold water stacks them in 8 to 40 ft. Top water on the chart: Break off the point, a drop-off in the 10 ft range, prime in winter. Fish it in early morning and the evening and you'll meet the bite. Throw a dodger + spoon (deep troll) or a flutter spoon until the fish tell you otherwise.

Spring brown trout on Lac Sainte-Marie hold shallow, usually 3 to 25 ft. They move out to 16 to 53 ft in summer and finish the year down in 5 to 35 ft. Put Deep basin first on the milk run — a deep basin near 52 ft that grades prime for summer. The feeding windows run after dark and early morning. The summer box starts with a spoon at the thermocline or a deep stickbait (night).

It's a deep basin holding about 52 ft of water and rates prime come summer. Prime time lands in early morning. A jigging spoon vertical or a tube jig (smelt) is the honest summer answer here.
