165-acre lake near Québec. The lake tops out around 39 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:
Drawn out, this is 165 acres of water rimmed by 2.7 miles of bank. Index 1.5 on the shoreline: a few honest points and pockets, nothing labyrinthine. Littoral water — the productive band under ~15 ft — makes up 89% of this chart. Tip to tip the water measures near 1.3 mi with a 0.3-mi widest point. The water lies in Pontiac MRC.

Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Warm water sends them out to 10 to 30 ft; cold water stacks them in 3 to 20 ft. Top water on the chart: Main-lake point, a point in the 3 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. 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 (3 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | Break off the point (7 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |

Early season walleye use the shallows, holding in 4 to 15 ft. Summer is a 15 to 35 ft game here, winter a 12 to 39 ft one. The chart's best answer is Deep basin — deep basin, 39 ft, prime for winter. Best bite is the evening and early morning. Tie on a crawler harness on bottom bouncer or a deep crankbait (trolled) and you're in the game.
