1,741-acre lake near Québec. The lake tops out around 250 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. Species by species, here's what the data says the year looks like.
Traced from the shoreline, Lac Marie-Le Franc runs 1,741 acres with 8.8 miles of edge. Index 1.5 on the shoreline: a few honest points and pockets, nothing labyrinthine.

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 Back-bay flat, a feeding flat in about 13 ft of water that rates good 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 50 to 120 ft, wintering in 20 to 80 ft. Top water on the chart: Main-lake point, a point in the 24 ft range, prime in spring. Time it for early morning. Summer baits: a white tube jig (deep) or a magnum spoon on downrigger gets it done.

| Printemps | 10 to 40 ft | dawn & dusk | Main-lake point (24 ft) | Casting spoon over shoals, Jerkbait (shallow) |

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: Main-lake point, a point in the 24 ft range, prime in fall. 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.

Spring brown trout on Lac Marie-Le Franc hold shallow, usually 3 to 25 ft. They move out to 25 to 60 ft in summer and finish the year down in 5 to 35 ft. Put Main-lake point first on the milk run — a point near 24 ft that grades prime for spring. The feeding windows run after dark and early morning. The summer box starts with a spoon at the thermocline or a deep stickbait (night).

It's a feeding flat holding about 13 ft of water and rates good come spring. Prime time lands in early morning. A jigging spoon vertical or a tube jig (smelt) is the honest summer answer here.
