63-acre lake in Sudbury District, Ontario. The lake tops out around 72 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. Species by species, here's what the data says the year looks like.
Traced from the shoreline, Secret Lake runs 63 acres with 2.1 miles of edge. The shoreline is moderately structured (index 1.9) — enough points and pockets to pattern. The shallow band under 15 ft claims about 35% of the surface on the model — that's where the groceries are. Tip to tip the water measures near 0.7 mi with a 0.4-mi widest point. The water lies in Sudbury District. The nearest mapped water is Middle Kenetogami L., 3 mi to the east.
Spring puts lake trout in skinny water — 10 to 40 ft is the zone. As the season builds they drop to 22 to 72 ft, wintering in 18 to 72 ft. Summer lake trout concentrate at Deep basin, a prime-rated deep basin around 61 ft. Warm-month bites cluster around early morning. A white tube jig (deep) or a magnum spoon on downrigger covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (18 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 22 to 72 ft | dawn | Deep basin (61 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (18 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 18 to 72 ft | dawn | Deep basin (61 ft) | White tube jig, Airplane jig |
