207-acre lake near Québec. The lake tops out around 35 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's the year, species by species, as the scoring engine sees it.
On the chart, Lac Trousers draws 207 acres inside 2.3 miles of shoreline. Its 1.1 shoreline index means few bank features; the contours below do the pattern work. About 57% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 0.9 mi long by 0.6 mi wide at the broadest reach. You'll find it in Memphrémagog MRC. For a second option, Lac Long Pond lies 1 mi northeast.

In spring, rainbow trout run shallow here, mostly 5 to 20 ft. Summer pushes them deeper, 8 to 30 ft, and winter fish settle into 7 to 35 ft. Break off the point is the standout, a drop-off at roughly 6 ft, rated prime for winter rainbow trout. Time it for early morning and the evening. You won't need more than a dodger + spoon (deep troll) or a flutter spoon most summer days.

When the water first warms, brown trout slide up into 3 to 25 ft. By summer they slide out to 11 to 35 ft, and by winter most fish are in 5 to 35 ft. If you only fish one area, make it Deep basin: a deep basin around 35 ft that scores prime in summer. In summer the feeding windows fall in after dark and early morning. Keep a spoon at the thermocline or a deep stickbait (night) rigged through the warm months.
