15-acre lake in Cochrane District, Ontario. The lake tops out around 46 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. Here is how the season plays out for each species, straight from the data behind the map.
Drawn out, this is 15 acres of water rimmed by 0.9 miles of bank. The shoreline is moderately structured (index 1.7) — enough points and pockets to pattern. Roughly 52% of the water is 15 ft or less as modeled, the band where the food chain lives. Call it 0.4 mi long. You'll find it in Cochrane District. Closest neighbour on DepthScout: Hutch Lake, 1 mi east of here.
Spring puts rainbow trout in skinny water — 5 to 20 ft is the zone. As the season builds they drop to 8 to 30 ft, wintering in 8 to 40 ft. Winter rainbow trout concentrate at Break off the point, a prime-rated drop-off around 21 ft. Warm-month bites cluster around early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (12 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (21 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (12 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (21 ft) | Jigging spoon, Tube jig (white) |
