221-acre lake near Québec. The lake tops out around 148 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.
The drawn water covers 221 acres wrapped in 5.1 miles of bank. The 2.4 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. About 11% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Figure 2.2 mi of water from one end to the other, 0.7 mi at the beam. Matawinie MRC claims this one. Its nearest charted neighbour, Lac Saint-Grégoire, is 1 mi to the northeast.

When the water first warms, brook trout slide up into 2 to 15 ft. Summer is a 10 to 30 ft game here, winter a 3 to 20 ft one. Start at Break off the point. It's a drop-off holding about 12 ft of water and rates prime come summer. The feeding windows run early morning and the evening. Keep a small spoon fished deep or a trolled lake-clear wobbler + worm rigged through the warm months.

Early season lake trout use the shallows, holding in 10 to 40 ft. Summer is a 50 to 120 ft game here, winter a 20 to 80 ft one. The chart's best answer is Main-lake point — point, 26 ft, prime for spring. Best bite is early morning. Tie on a white tube jig (deep) or a magnum spoon on downrigger and you're in the game.

Spring puts arctic char in skinny water — 4 to 15 ft is the zone. Warm water sends them out to 20 to 60 ft; cold water stacks them in 10 to 40 ft. Break off the point is the standout, a drop-off at roughly 12 ft, rated prime for spring arctic char. Plan around early morning in the warm months. A jigging spoon vertical or a tube jig (smelt) covers the summer program.

Shallow bay flat is the standout, a feeding flat at roughly 32 ft, rated prime for spring lake whitefish. Plan around early morning in the warm months. A blade bait vertical or a small jigging spoon covers the summer program.

Start shallow in spring: walleye sit in 4 to 15 ft that time of year. Summer pushes them deeper, 15 to 35 ft, and winter fish settle into 20 to 40 ft. The spot to know is Break off the point, a drop-off in about 12 ft of water that rates prime for walleye in fall. Warm-month bites cluster around the evening and early morning. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.
