437-acre lake near Québec. The lake tops out around 53 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. The rest of this page walks each species through its year, using the map's own scoring.
Traced from the shoreline, Lac Ludger runs 437 acres with 5 miles of edge. Index 1.7 on the shoreline: a few honest points and pockets, nothing labyrinthine. 59% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Tip to tip the water measures near 1.6 mi with a 1-mi widest point. The water lies in Les Laurentides MRC. For a second option, Lac Cardin lies 1 mi northeast.

The spring pattern is a shallow one: brook trout in 2 to 15 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 3 to 20 ft for winter. The spot to know is Main-lake point, a point in about 9 ft of water that rates prime for brook trout in spring. Plan around early morning and the evening in the warm months. Summer baits: a small spoon fished deep or a trolled lake-clear wobbler + worm gets it done.

The spring pattern is a shallow one: lake trout in 10 to 40 ft. As the season builds they drop to 16 to 53 ft, wintering in 13 to 53 ft. Top water on the chart: Deep basin, a deep basin in the 51 ft range, prime in summer. Time it for early morning. Summer baits: a white tube jig (deep) or a magnum spoon on downrigger gets it done.

Start shallow in spring: rainbow trout sit in 5 to 20 ft that time of year. Warm water sends them out to 8 to 30 ft; cold water stacks them in 8 to 40 ft. Top water on the chart: Break off the point, a drop-off in the 6 ft range, prime in winter. Fish it in early morning and the evening and you'll meet the bite. Throw a dodger + spoon (deep troll) or a flutter spoon until the fish tell you otherwise.
