14-acre lake near Québec. The lake tops out around 13 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The rest of this page walks each species through its year, using the map's own scoring.
The drawn water covers 14 acres wrapped in 0.6 miles of bank. At index 1.2 the outline is almost a bowl — read the depth changes, not the shoreline. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. Call it 0.3 mi long. La Rivière-du-Nord MRC claims this one. Its nearest charted neighbour, Lac Montaubois, is 0 mi to the north.

Spring rainbow trout on Lac Desjardins hold shallow, usually 3 to 13 ft. Depth-wise the year is flat: 3 to 13 ft in summer, 3 to 13 ft once it turns cold. Put Break off the point first on the milk run — a drop-off near 10 ft that grades prime for winter. The feeding windows run early morning and the evening. The summer box starts with a dodger + spoon (deep troll) or a flutter spoon.
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 | 3 to 13 ft chart-limited; documented 5 to 20 ft | dawn & dusk | Main-lake point (4 ft) | Inline spinner (silver), Small spoon |
| Été | 3 to 13 ft chart-limited; documented 8 to 30 ft | dawn & dusk | Break off the point (10 ft) | Dodger + spoon (deep troll), Flutter spoon |

In spring, brown trout run shallow here, mostly 2 to 13 ft. Summer keeps them at 4 to 13 ft, and they winter in 2 to 13 ft. Break off the point is the standout, a drop-off at roughly 10 ft, rated prime for summer brown trout. Time it for after dark and early morning. You won't need more than a spoon at the thermocline or a deep stickbait (night) most summer days.

In spring, walleye run shallow here, mostly 3 to 13 ft. Summer keeps them at 4 to 13 ft, and they winter in 4 to 13 ft. Break off the point is the standout, a drop-off at roughly 10 ft, rated prime for fall walleye. Time it for the evening and early morning. You won't need more than a crawler harness on bottom bouncer or a deep crankbait (trolled) most summer days.

The spring pattern is a shallow one: yellow perch in 3 to 12 ft. As the season builds they drop to 4 to 13 ft, wintering in 4 to 13 ft. Top water on the chart: Deep basin, a deep basin in the 12 ft range, prime in fall. Time it for early morning. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.

When the water first warms, northern pike slide up into 2 to 8 ft. By summer they slide out to 4 to 13 ft, and by winter most fish are in 4 to 13 ft. If you only fish one area, make it Break off the point: a drop-off around 10 ft that scores prime in fall. In summer the feeding windows fall in early morning and the evening. Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.

Come spring, look for muskellunge tight to the bank in 3 to 12 ft. They move out to 4 to 13 ft in summer and finish the year down in 4 to 13 ft. If you only fish one area, make it Break off the point: a drop-off around 10 ft that scores prime in fall. Best bite is the evening and early morning. A double-10 bucktail or a topwater (walk-the-dog / creeper) is the honest summer answer here.

Anglers target rainbow trout, brown trout, walleye, yellow perch, northern pike, muskellunge, smallmouth bass, largemouth bass, rock bass, crappie, pumpkinseed, brown bullhead, channel catfish, longnose gar on Lac Desjardins. 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.
Break off the point is the top-rated area: a drop-off in about 10 ft of water that rates prime for walleye in fall. Every other rated spot, per species and season, is on the map above.
For rainbow 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.
