11-acre lake in Renfrew County, Ontario. The lake tops out around 28 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. Every species below gets its seasonal read from the same numbers driving the chart.
The drawn water covers 11 acres wrapped in 0.8 miles of bank. A middling shoreline index (1.7) gives it some bays to work without being a maze. Roughly 69% of the water is 15 ft or less as modeled, the band where the food chain lives. Call it 0.4 mi long. Renfrew County claims this one. Lower Twin Lake sits 0 mi south — the closest neighbouring chart.
When the water first warms, brook trout slide up into 2 to 15 ft. Summer is an 8 to 28 ft game here, winter a 3 to 20 ft one. Start at Deep basin. It's a deep basin holding about 24 ft of water and rates prime come summer. The feeding windows run early morning and the evening. Keep a small spoon fished deep or a trolled lake-clear wobbler + worm rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (8 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 8 to 28 ft | dawn & dusk | Deep basin (24 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
