1,000-acre lake near Saint-Raymond. The lake tops out around 57 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.
The outline encloses 952 acres, worked by 8.2 miles of shoreline. With a 1.9 development index there's bank structure worth casting at, in moderation. About 36% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The basin spans about 2.5 mi end to end and 1.6 mi across at its widest. It sits in Portneuf MRC. If the bite dies, Lac Alain is 4 mi to the west.

Early season brook trout use the shallows, holding in 2 to 15 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 3 to 20 ft. Put Main-lake point first on the milk run — a point near 7 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.
| 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 |

When the water first warms, lake trout slide up into 10 to 40 ft. By summer they slide out to 17 to 57 ft, and by winter most fish are in 14 to 57 ft. If you only fish one area, make it Deep basin: a deep basin around 55 ft that scores prime in summer. In summer the feeding windows fall in early morning. Keep a white tube jig (deep) or a magnum spoon on downrigger rigged through the warm months.

Start shallow in spring: arctic char sit in 4 to 15 ft that time of year. Summer pushes them deeper, 17 to 57 ft, and winter fish settle into 10 to 40 ft. The spot to know is Deep basin, a deep basin in about 55 ft of water that rates prime for arctic char in summer. Warm-month bites cluster around early morning. Throw a jigging spoon vertical or a tube jig (smelt) until the fish tell you otherwise.

Start shallow in spring: lake whitefish sit in 15 to 45 ft that time of year. Summer pushes them deeper, 17 to 57 ft, and winter fish settle into 17 to 57 ft. The spot to know is Deep basin, a deep basin in about 55 ft of water that rates prime for lake whitefish in summer. Warm-month bites cluster around early morning. Throw a blade bait vertical or a small jigging spoon until the fish tell you otherwise.

Start shallow in spring: cisco (lake herring) sit in 10 to 40 ft that time of year. Summer pushes them deeper, 17 to 57 ft, and winter fish settle into 17 to 57 ft. The spot to know is Deep basin, a deep basin in about 55 ft of water that rates prime for cisco (lake herring) in summer. Warm-month bites cluster around early morning. Throw a vertical flutter spoon (small) or a drop-shot micro plastic until the fish tell you otherwise.

In spring, walleye run shallow here, mostly 4 to 15 ft. Midsummer fish sit out in 15 to 35 ft before dropping to 20 to 40 ft for winter. Fall walleye concentrate at Break off the point, a prime-rated drop-off around 32 ft. Fish it in the evening and early morning and you'll meet the bite. You won't need more than a crawler harness on bottom bouncer or a deep crankbait (trolled) most summer days.
