489-acre lake near Québec. The lake tops out around 26 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 Osisko (no 2) draws 489 acres inside 4 miles of shoreline. At index 1.3 the outline is almost a bowl — read the depth changes, not the shoreline. 55% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Figure 1.6 mi of water from one end to the other, 0.7 mi at the beam. You'll find it in Rouyn-Noranda. The nearest mapped water is Lac Noranda, 2 mi to the west.

The spring pattern is a shallow one: brook trout in 2 to 15 ft. As the season builds they drop to 8 to 26 ft, wintering in 3 to 20 ft. Top water on the chart: Deep basin, a deep basin in the 25 ft range, prime in summer. Time it for early morning and the evening. 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 (5 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 8 to 26 ft | dawn & dusk | Deep basin (25 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 2 to 15 ft | midday & dawn | Main-lake point (5 ft) | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Break off the point (16 ft) | Small jigging spoon, Tungsten jig + plastic |
Start shallow in spring: rainbow trout sit in 5 to 20 ft that time of year. Summer pushes them deeper, 7 to 26 ft, and winter fish settle into 5 to 26 ft. The spot to know is Break off the point, a drop-off in about 16 ft of water that rates prime for rainbow trout in winter. Warm-month bites cluster around early morning and the evening. Throw a dodger + spoon (deep troll) or a flutter spoon until the fish tell you otherwise.

Spring walleye on Lac Osisko (no 2) hold shallow, usually 4 to 15 ft. By summer they slide out to 8 to 26 ft, and by winter most fish are in 8 to 26 ft. The chart's best answer is Break off the point — drop-off, 16 ft, prime for fall. Prime time lands in the evening and early morning. The summer box starts with a crawler harness on bottom bouncer or a deep crankbait (trolled).
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 4 to 15 ft | dusk & dawn | Main-lake point (5 ft) | 1/8 oz jig + minnow, Hair jig |
| Été | 8 to 26 ft | dusk & dawn | Break off the point (16 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Automne | 8 to 26 ft | dusk & night | Break off the point (16 ft) | Jigging rap, Jig + big minnow |
| Hiver | 8 to 26 ft | dusk & dawn | Deep basin (25 ft) | Jigging spoon + minnow head, Rattle bait |
Come spring, look for sauger tight to the bank in 4 to 18 ft. Expect a summer slide to 8 to 26 ft, then a winter hold in 8 to 26 ft. Start at Deep basin. It's a deep basin holding about 25 ft of water and rates prime come winter. Prime time lands in early morning and the evening. A bottom bouncer + crawler or a 3-way rig with stickbait is the honest summer answer here.

|---|---|---|---|---|
| Printemps | 4 to 18 ft | dawn & dusk | Main-lake point (5 ft) | 3/8 oz jig + ringworm, Hair jig + minnow |

| Hiver | 8 to 26 ft | dusk | Deep basin (25 ft) | Heavy jigging spoon, Jig + minnow (vertical) |
Early season yellow perch use the shallows, holding in 3 to 12 ft. Summer is an 8 to 26 ft game here, winter an 8 to 26 ft one. The chart's best answer is Back-bay flat — weed flat, 8 ft, prime for spring. Best bite is early morning. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 3 to 12 ft | midday & dawn | Back-bay flat (8 ft) | Small jig + curly tail, Perch-pattern micro crank |

In spring, northern pike run shallow here, mostly 2 to 8 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 5 to 15 ft for winter. Spring northern pike concentrate at Shallow bay flat, a prime-rated weed flat around 2 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a bucktail or a weedless spoon over cabbage most summer days.

|---|---|---|---|---|
| Printemps | 2 to 8 ft | midday & dawn | Shallow bay flat (2 ft) | #5 inline spinner, Spoon (red/white) |
