76-acre lake near Québec. The lake tops out around 46 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 season-by-season read for each species follows, from the map's own numbers.
On the chart, Lac du Coteau draws 76 acres inside 2.7 miles of shoreline. A development index of 2.2 means a maze of bays and points: far more casting targets than a round bowl of the same size. Roughly 42% of the water is 15 ft or less, the band where the food chain lives. Figure 1.2 mi of water from one end to the other, 0.2 mi at the beam. You'll find it in Matawinie MRC. For a second option, Lac de la Baie lies 1 mi east.

Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 3 to 20 ft. The spot to know is Break off the point, a drop-off in about 26 ft of water that rates prime for brook trout in summer. Warm-month bites cluster around early morning and the evening. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.
| 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 (26 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 (6 ft) | Small jigging spoon, Tungsten jig + plastic |
The spring pattern is a shallow one: landlocked salmon in 1 to 15 ft. As the season builds they drop to 14 to 46 ft, wintering in 10 to 40 ft. Top water on the chart: Deep basin, a deep basin in the 43 ft range, prime in summer. Time it for early morning and the evening. Summer baits: a dodger + streamer down deep or a thin spoon on lead core gets it done.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 1 to 15 ft | dawn & dusk | Main-lake point (7 ft) | Streamer flies (Grey Ghost) off boards, Thin spoon (Mooselook style) |
| Été | 14 to 46 ft | dawn & dusk | Deep basin (43 ft) | Dodger + streamer down deep, Thin spoon on lead core |
| Automne | 5 to 30 ft | dawn & dusk | Main-lake point (7 ft) | Casting spoon at the mouths, Streamers |
| Hiver | 10 to 40 ft | dawn | Break off the point (26 ft) | Small jigging spoon, Swedish pimple + smelt |
Early season walleye use the shallows, holding in 4 to 15 ft. Expect a summer slide to 15 to 35 ft, then a winter hold in 20 to 40 ft. Put Break off the point first on the milk run — a drop-off near 26 ft that grades prime for fall. In summer the feeding windows fall in the evening and early morning. Tie on a crawler harness on bottom bouncer or a deep crankbait (trolled) and you're in the game.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 4 to 15 ft | dusk & dawn | Main-lake point (7 ft) | 1/8 oz jig + minnow, Hair jig |
| Été | 15 to 35 ft | dusk & dawn | Break off the point (26 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |

| Hiver | 20 to 40 ft | dusk & dawn | Deep basin (43 ft) | Jigging spoon + minnow head, Rattle bait |
Spring yellow perch on Lac du Coteau hold shallow, usually 3 to 12 ft. They move out to 10 to 30 ft in summer and finish the year down in 15 to 35 ft. Put Shallow bay flat first on the milk run — a weed flat near 6 ft that grades prime for spring. The feeding windows run early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 3 to 12 ft | midday & dawn | Shallow bay flat (6 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Été | 10 to 30 ft | dawn | Break off the point (26 ft) | Drop-shot micro plastics, Small spoon tipped with worm |

Spring puts northern pike in skinny water — 2 to 8 ft is the zone. Warm water sends them out to 8 to 20 ft; cold water stacks them in 5 to 15 ft. Shallow bay flat is the standout, a weed flat at roughly 6 ft, rated prime for spring northern pike. Plan around early morning and the evening in the warm months. A bucktail or a weedless spoon over cabbage covers the summer program.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 2 to 8 ft | midday & dawn | Shallow bay flat (6 ft) | #5 inline spinner, Spoon (red/white) |
