21-acre lake in Nipissing District, Ontario. The lake tops out around 30 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. Here is how the season plays out for each species, straight from the data behind the map.
Drawn out, this is 21 acres of water rimmed by 1.2 miles of bank. Index 1.8 on the shoreline: a few honest points and pockets, nothing labyrinthine. Roughly 65% of the water is 15 ft or less as modeled, the band where the food chain lives. Tip to tip the water measures near 0.4 mi with a 0.2-mi widest point. You'll find it in Nipissing District. The nearest mapped water is Skunk Lake, 1 mi to the southwest.
The spring pattern is a shallow one: rainbow trout in 5 to 20 ft. As the season builds they drop to 8 to 30 ft, wintering in 6 to 30 ft. Top water on the chart: Break off the point, a drop-off in the 14 ft range, prime in winter. Time it for early morning and the evening. Summer baits: a dodger + spoon (deep troll) or a flutter spoon gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (14 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 9 to 30 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 6 to 30 ft | dawn | Break off the point (14 ft) | Jigging spoon, Tube jig (white) |
