423-acre lake near Québec. The lake tops out around 140 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. Every species below gets its seasonal read from the same numbers driving the chart.
Traced from the shoreline, Lac Lyster runs 423 acres with 3.5 miles of edge. The basin is a simple one (shoreline index 1.2) — close to a bowl, so the structure on the chart matters more than the bank. Roughly 13% of the water is 15 ft or less, the band where the food chain lives. End to end it runs roughly 1.5 mi, about 0.6 mi across. You'll find it in Coaticook MRC. For a second option, Holland Pond lies 3 mi south.

In spring, brook trout run shallow here, mostly 2 to 15 ft. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 3 to 20 ft. Main-lake point is the standout, a point at roughly 9 ft, rated prime for spring brook trout. Time it for early morning and the evening. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.

Spring puts lake trout in skinny water — 10 to 40 ft is the zone. Warm water sends them out to 50 to 120 ft; cold water stacks them in 20 to 80 ft. Break off the point is the standout, a drop-off at roughly 67 ft, rated prime for winter lake trout. Plan around early morning in the warm months. A white tube jig (deep) or a magnum spoon on downrigger covers the summer program.

Spring puts rainbow trout in skinny water — 5 to 20 ft is the zone. As the season builds they drop to 8 to 30 ft, wintering in 8 to 40 ft. Spring rainbow trout concentrate at Main-lake point, a prime-rated point around 9 ft. Warm-month bites cluster around early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon covers the summer program.

Come spring, look for brown trout tight to the bank in 3 to 25 ft. Expect a summer slide to 25 to 60 ft, then a winter hold in 5 to 35 ft. Start at Main-lake point. It's a point holding about 9 ft of water and rates prime come spring. Prime time lands in after dark and early morning. A spoon at the thermocline or a deep stickbait (night) is the honest summer answer here.
