307-acre lake near Québec. The lake tops out around 66 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. Every species below gets its seasonal read from the same numbers driving the chart.
Lac Harrington maps at 307 acres behind 3.5 miles of shoreline. The basin is a simple one (shoreline index 1.4) — close to a bowl, so the structure on the chart matters more than the bank. About 20% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Tip to tip the water measures near 1.4 mi with a 0.7-mi widest point. It sits in Argenteuil MRC. Its nearest charted neighbour, Lac Fawn, is 1 mi to the north.

Early season lake trout use the shallows, holding in 10 to 40 ft. Expect a summer slide to 20 to 66 ft, then a winter hold in 17 to 66 ft. Put Deep basin first on the milk run — a deep basin near 66 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.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 10 to 40 ft | dawn & dusk | Main-lake point (10 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Été | 20 to 66 ft | dawn | Deep basin (66 ft) | White tube jig (deep), Magnum spoon on downrigger |

Come spring, look for rainbow trout tight to the bank in 5 to 20 ft. Expect a summer slide to 8 to 30 ft, then a winter hold in 8 to 40 ft. Start at Break off the point. It's a drop-off holding about 42 ft of water and rates prime come winter. Prime time lands in early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon is the honest summer answer here.

Start shallow in spring: brown trout sit in 3 to 25 ft that time of year. Warm water sends them out to 25 to 60 ft; cold water stacks them in 5 to 35 ft. Top water on the chart: Break off the point, a drop-off in the 42 ft range, prime in summer. Fish it in after dark and early morning and you'll meet the bite. Throw a spoon at the thermocline or a deep stickbait (night) until the fish tell you otherwise.

Spring puts lake whitefish in skinny water — 15 to 45 ft is the zone. As the season builds they drop to 20 to 66 ft, wintering in 20 to 66 ft. Summer lake whitefish concentrate at Deep basin, a prime-rated deep basin around 66 ft. Warm-month bites cluster around early morning. A blade bait vertical or a small jigging spoon covers the summer program.

Top water on the chart: Break off the point, a drop-off in the 42 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.

Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 10 to 30 ft; cold water stacks them in 15 to 35 ft. Shallow bay flat is the standout, a feeding flat at roughly 7 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.
