185-acre lake near Québec. The lake tops out around 87 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.
Lac des Îles maps at 185 acres behind 2.3 miles of shoreline. The basin is a simple one (shoreline index 1.2) — close to a bowl, so the structure on the chart matters more than the bank. About 32% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Tip to tip the water measures near 0.9 mi with a 0.5-mi widest point. It sits in Maskinongé MRC. Its nearest charted neighbour, Lac des Six, is 1 mi to the northeast.

When the water first warms, brook trout slide up into 2 to 15 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 3 to 20 ft. If you only fish one area, make it Main-lake point: a point around 11 ft that scores prime in spring. In summer the feeding windows fall in 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. Expect a summer slide to 26 to 87 ft, then a winter hold in 20 to 80 ft. Put Deep basin first on the milk run — a deep basin near 85 ft that grades prime for summer. In summer the feeding windows fall in early morning. Tie on a white tube jig (deep) or a magnum spoon on downrigger and you're in the game.

A jigging spoon vertical or a tube jig (smelt) covers the summer program.

Start shallow in spring: walleye sit in 4 to 15 ft that time of year. Warm water sends them out to 15 to 35 ft; cold water stacks them in 20 to 40 ft. Top water on the chart: Secondary point, a point in the 19 ft range, prime in fall. Fish it in the evening and early morning and you'll meet the bite. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.
