86-acre lake near Québec. The lake tops out around 7 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. Below is the species-by-species picture, pulled from the same data the map uses.
Lac Dion maps at 86 acres behind 1.6 miles of shoreline. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. Tip to tip the water measures near 0.7 mi with a 0.3-mi widest point. Bellechasse MRC claims this one. If the bite dies, Lac Vert is 3 mi to the northwest.

Spring brook trout on Lac Dion hold shallow, usually 1 to 7 ft. Depth-wise the year is flat: 2 to 7 ft in summer, 1 to 7 ft once it turns cold. Put Deep basin first on the milk run — a deep basin near 7 ft that grades prime for summer. The feeding windows run early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.

The chart's best answer is Break off the point — drop-off, 7 ft, prime for winter. Best bite is early morning and the evening. Tie on a dodger + spoon (deep troll) or a flutter spoon and you're in the game.

Start shallow in spring: yellow perch sit in 2 to 7 ft that time of year. They don't go far with the seasons — 2 to 7 ft covers summer, 2 to 7 ft covers winter. The spot to know is Shallow bay flat, a weed flat in about 2 ft of water that rates prime for yellow perch in spring. Warm-month bites cluster around early morning. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.
