43-acre lake near Québec. The lake tops out around 33 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. What the data behind the map says about each species, season by season:
On the chart, Lac Leroux draws 43 acres inside 1.1 miles of shoreline. The basin is a simple one (shoreline index 1.2) — close to a bowl, so the structure on the chart matters more than the bank. About 31% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. End to end it runs roughly 0.4 mi, about 0.2 mi across. The water lies in Les Laurentides MRC. The nearest mapped water is Lac Noir, 1 mi to the east.

The spring pattern is a shallow one: brook trout in 2 to 15 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 3 to 20 ft for winter. The spot to know is Main-lake point, a point in about 7 ft of water that rates prime for brook trout in spring. Plan around early morning and the evening in the warm months. Summer baits: a small spoon fished deep or a trolled lake-clear wobbler + worm gets it done.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Main-lake point (7 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | Break off the point (32 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 2 to 15 ft | midday & dawn | Main-lake point (7 ft) | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Shallow bay flat (4 ft) | Small jigging spoon, Tungsten jig + plastic |
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 7 to 33 ft. Top water on the chart: Break off the point, a drop-off in the 32 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 Leroux hold shallow, usually 3 to 25 ft. They move out to 10 to 33 ft in summer and finish the year down in 5 to 33 ft. Put Break off the point first on the milk run — a drop-off near 32 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).

Early season yellow perch use the shallows, holding in 3 to 12 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 10 to 33 ft. Put Shallow bay flat first on the milk run — a weed flat near 4 ft that grades prime for spring. In summer the feeding windows fall in early morning. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.

In spring, northern pike run shallow here, mostly 2 to 8 ft. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 5 to 15 ft. Shallow bay flat is the standout, a weed flat at roughly 4 ft, rated prime for spring northern pike. Time it for early morning and the evening. You won't need more than a bucktail or a weedless spoon over cabbage most summer days.
