75-acre lake near Québec. The lake tops out around 50 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:
The drawn water covers 75 acres wrapped in 1.5 miles of bank. Nearly circular (index 1.2), so the story is the bottom, not the bank. About 28% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. End to end it runs roughly 0.6 mi, about 0.3 mi across. It sits in La Jacques-Cartier MRC. If the bite dies, Lac Nevair is 1 mi to the northwest.

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 Shallow bay flat first on the milk run — a weed flat near 12 ft that grades good 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 | Shallow bay flat (12 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | open water | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 2 to 15 ft | midday & dawn | open water | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Shallow bay flat (12 ft) | Small jigging spoon, Tungsten jig + plastic |
When the water first warms, lake trout slide up into 10 to 40 ft. By summer they slide out to 15 to 50 ft, and by winter most fish are in 13 to 50 ft. If you only fish one area, make it Deep basin: a deep basin around 50 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, 15 to 50 ft, and winter fish settle into 10 to 40 ft. The spot to know is Deep basin, a deep basin in about 50 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, 15 to 50 ft, and winter fish settle into 15 to 50 ft. The spot to know is Deep basin, a deep basin in about 50 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, 15 to 50 ft, and winter fish settle into 15 to 50 ft. The spot to know is Deep basin, a deep basin in about 50 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. Summer walleye concentrate at Back-bay flat, a good-rated weed flat around 15 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.
