171-acre lake near Québec. The lake tops out around 20 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here is how the season plays out for each species, straight from the data behind the map.
The outline encloses 171 acres, worked by 2.9 miles of shoreline. With a 1.6 development index there's bank structure worth casting at, in moderation. 78% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. End to end it runs roughly 1.4 mi, about 0.3 mi across. Québec claims this one. If the bite dies, Lac Bonhomme is 8 mi to the northwest.

Spring brook trout on Lac Saint-Augustin hold shallow, usually 2 to 15 ft. They move out to 6 to 20 ft in summer and finish the year down in 3 to 20 ft. Put Deep basin first on the milk run — a deep basin near 20 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.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Main-lake point (1 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 6 to 20 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Deep basin (20 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |

Spring puts brown trout in skinny water — 2 to 20 ft is the zone. Summer fish stay in 6 to 20 ft, and winter fish hold in 3 to 20 ft. Summer brown trout concentrate at Break off the point, a prime-rated drop-off around 16 ft. Warm-month bites cluster around after dark and early morning. A spoon at the thermocline or a deep stickbait (night) covers the summer program.

Early season landlocked salmon use the shallows, holding in 1 to 15 ft. Summer is a 6 to 20 ft game here, winter a 5 to 20 ft one. The chart's best answer is Deep basin — deep basin, 20 ft, prime for summer. Best bite is early morning and the evening. Tie on a dodger + streamer down deep or a thin spoon on lead core and you're in the game.

Spring puts walleye in skinny water — 4 to 15 ft is the zone. As the season builds they drop to 6 to 20 ft, wintering in 6 to 20 ft. Fall walleye concentrate at Break off the point, a prime-rated drop-off around 16 ft. Warm-month bites cluster around the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) covers the summer program.

| Printemps | 4 to 15 ft | dusk & dawn | Break off the point (16 ft) | 1/8 oz jig + minnow, Hair jig |

In spring, sauger run shallow here, mostly 4 to 18 ft. Midsummer fish sit out in 6 to 20 ft before dropping to 6 to 20 ft for winter. Winter sauger concentrate at Deep basin, a prime-rated deep basin around 20 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a bottom bouncer + crawler or a 3-way rig with stickbait most summer days.

Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Summer pushes them deeper, 6 to 20 ft, and winter fish settle into 6 to 20 ft. The spot to know is Deep basin, a deep basin in about 20 ft of water that rates prime for yellow perch in fall. 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.

Deep basin is the top-rated area: a deep basin in about 20 ft of water that rates prime for landlocked salmon in summer. 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.
