329-acre lake near Saint-Léonard-de-Portneuf. The lake tops out around 117 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 326 acres wrapped in 3.9 miles of bank. A middling shoreline index (1.5) gives it some bays to work without being a maze. Littoral water — the productive band under ~15 ft — makes up 14% of this chart. Tip to tip the water measures near 1.3 mi with a 0.8-mi widest point. Portneuf MRC claims this one. Lac de l'Oasis sits 2 mi northeast — the closest neighbouring chart.

Come spring, look for brook trout tight to the bank in 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. If you only fish one area, make it Creek inflow: an inflow / creek mouth around 5 ft that scores prime in spring. Best bite is early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.

Spring lake trout on Lac Simon hold shallow, usually 10 to 40 ft. They move out to 35 to 117 ft in summer and finish the year down in 20 to 80 ft. Put Deep basin first on the milk run — a deep basin near 116 ft that grades prime for summer. The feeding windows run early morning. The summer box starts with a white tube jig (deep) or a magnum spoon on downrigger.

Early season chinook salmon use the shallows, holding in 5 to 40 ft. Summer is a 35 to 117 ft game here, winter a 30 to 90 ft one. The chart's best answer is Creek inflow — inflow / creek mouth, 5 ft, prime for spring. Best bite is early morning and the evening. Tie on a flasher + fly (green/white) or a magnum spoon on downrigger and you're in the game.

Anglers target brook trout, lake trout, chinook salmon, arctic char, lake whitefish, cisco (lake herring), walleye, yellow perch, northern pike, burbot on Lac Simon. This species list is an informed estimate from Québec's provincial fish-range maps (bounded by each lake's depth and habitat), not a per-lake fish survey — Québec doesn't publish per-lake species records.
Creek inflow is the top-rated area: an inflow / creek mouth in about 5 ft of water that rates prime for brook trout in spring. Scroll up to the map for the complete spot list by species and season.
For brook trout, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
