14-acre lake near Québec. The lake tops out around 10 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. The season-by-season read for each species follows, from the map's own numbers.
The drawn water covers 14 acres wrapped in 0.6 miles of bank. Nearly circular (index 1.2), so the story is the bottom, not the bank. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. Tip to tip the water measures near 0.3 mi. It sits in La Vallée-de-la-Gatineau MRC. If the bite dies, Lac Parenteau is 0 mi to the east.

When the water first warms, brook trout slide up into 1 to 10 ft. There's no big seasonal slide here — summer means 3 to 10 ft, winter 2 to 10 ft. If you only fish one area, make it Deep basin: a deep basin around 10 ft that scores prime in summer. 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.

| Printemps | 1 to 10 ft | dawn & dusk | Shallow bay flat (4 ft) | Small inline spinner (gold), Tiny spoon |

Start shallow in spring: walleye sit in 3 to 10 ft that time of year. They don't go far with the seasons — 3 to 10 ft covers summer, 3 to 10 ft covers winter. Top water on the chart: Deep basin, a deep basin in the 10 ft range, prime in winter. 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.

Spring puts yellow perch in skinny water — 3 to 10 ft is the zone. Summer fish stay in 3 to 10 ft, and winter fish hold in 3 to 10 ft. Shallow bay flat is the standout, a weed flat at roughly 4 ft, rated prime for spring yellow perch. Plan around early morning in the warm months. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.

Anglers target brook trout, walleye, yellow perch, northern pike, rock bass, pumpkinseed on Lac Fastes. 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.
Deep basin is the top-rated area: a deep basin in about 10 ft of water that rates prime for walleye in winter. Open the map above to see every rated spot for each 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.
