8,295-acre lake near Québec. The lake tops out around 197 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. Here is how the season plays out for each species, straight from the data behind the map.
Traced from the shoreline, Lac Opasatica runs 8,295 acres with 44.9 miles of edge. A development index of 3.5 means a maze of bays and points: far more casting targets than a round bowl of the same size. Roughly 30% of the water is 15 ft or less, the band where the food chain lives. End to end it runs roughly 12.5 mi, about 5.7 mi across. You'll find it in Rouyn-Noranda. The nearest mapped water is Boundary L.s, 9 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 10 to 30 ft, wintering in 3 to 20 ft. Top water on the chart: Sharp break, a drop-off in the 26 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 (4 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | Sharp break (26 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 2 to 15 ft | midday & dawn | Main-lake point (4 ft) | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Break off the point (7 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, 8 to 30 ft, and winter fish settle into 8 to 40 ft. The spot to know is Rock reef, a rock pile in about 11 ft of water that rates prime for rainbow trout in fall. 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.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 5 to 20 ft | dawn & dusk | Shoreline point (8 ft) | Inline spinner (silver), Small spoon |
| Été | 8 to 30 ft | dawn & dusk | Rock reef (11 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Automne | 10 to 35 ft | dawn & dusk | Rock reef (11 ft) | Casting spoon, Jerkbait over shoals |
| Hiver | 8 to 40 ft | dawn | Sharp break (26 ft) | Jigging spoon, Tube jig (white) |
Come spring, look for lake whitefish tight to the bank in 15 to 45 ft. They move out to 40 to 90 ft in summer and finish the year down in 25 to 70 ft. If you only fish one area, make it Rock reef: a rock pile around 11 ft that scores prime in fall. Best bite is early morning. A blade bait vertical or a small jigging spoon is the honest summer answer here.

| Printemps | 15 to 45 ft | midday & dawn | Sharp break (26 ft) | Small jig + waxworm, Blade bait (small) |
| Été | 40 to 90 ft | dawn | Deep basin (98 ft) | Blade bait vertical, Small jigging spoon |
| Automne | 8 to 30 ft | dusk | Rock reef (11 ft) | Small spoon (gold), Jig + plastic larva |
| Hiver | 25 to 70 ft | midday & dawn | Sharp break (26 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Come spring, look for cisco (lake herring) tight to the bank in 10 to 40 ft. They move out to 40 to 80 ft in summer and finish the year down in 20 to 60 ft. If you only fish one area, make it Rock reef: a rock pile around 5 ft that scores prime in fall. Best bite is early morning. A vertical flutter spoon (small) or a drop-shot micro plastic is the honest summer answer here.

Spring walleye on Lac Opasatica hold shallow, usually 4 to 15 ft. By summer they slide out to 15 to 35 ft, and by winter most fish are in 20 to 40 ft. The chart's best answer is Sharp break — drop-off, 26 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 | Rock reef (5 ft) | 1/8 oz jig + minnow, Hair jig |

| Automne | 12 to 40 ft | dusk & night | Sharp break (26 ft) | Jigging rap, Jig + big minnow |
| Hiver | 20 to 40 ft | dusk & dawn | Sharp break (26 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 10 to 30 ft, then a winter hold in 15 to 45 ft. Start at Rock reef. It's a rock pile holding about 5 ft of water and rates prime come spring. 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.

Rock reef is the top-rated area: a rock pile in about 11 ft of water that rates prime for lake whitefish in fall. The map above holds the full rated-spot list for every species and season.
For brook trout, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
