Rating depth structure for lake trout.

238-acre lake in Parry Sound District, Ontario. The lake tops out around 148 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. What follows comes from the same scoring engine that paints the spots above.
Drawn out, this is 237 acres of water rimmed by 5.5 miles of bank, with a single island in the mix. A development index of 2.5 means a maze of bays and points: far more casting targets than a round bowl of the same size. 27% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Call it 1.4 mi long by 0.6 mi wide at the broadest reach. The water lies in Parry Sound District. Closest neighbour on DepthScout: Lower Raven Lake, 1 mi east of here.
Spring puts lake trout in skinny water — 10 to 40 ft is the zone. As the season builds they drop to 50 to 120 ft, wintering in 20 to 80 ft. Summer lake trout concentrate at Deep basin, a prime-rated deep basin around 126 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 (37 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 50 to 120 ft | dawn | Deep basin (126 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (37 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Break off the point (67 ft) | White tube jig, Airplane jig |
