37-acre lake near Québec. The lake tops out around 30 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:
Traced from the shoreline, Lac à l'Île runs 37 acres with 1 miles of edge. Its 1.2 shoreline index means few bank features; the contours below do the pattern work. Roughly 79% of the water is 15 ft or less, the band where the food chain lives. Tip to tip the water measures near 0.4 mi with a 0.2-mi widest point. You'll find it in Matawinie MRC. The nearest mapped water is Lac Prévost, 0 mi to the south.

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 Deep basin, a deep basin in about 29 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 (2 ft) | Small inline spinner (gold), Tiny spoon |

| Hiver | 3 to 20 ft | dawn | Break off the point (3 ft) | Small jigging spoon, Tungsten jig + plastic |
Early season walleye use the shallows, holding in 4 to 15 ft. Expect a summer slide to 9 to 30 ft, then a winter hold in 9 to 30 ft. Put Deep basin first on the milk run — a deep basin near 29 ft that grades prime for winter. 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.

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 2 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.
