16-acre lake in Grey County, Ontario. The lake tops out around 7 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 16 acres wrapped in 0.7 miles of bank. The basin is a simple one (shoreline index 1.3) — close to a bowl, so the structure on the chart matters more than the bank. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. Grey County claims this one. Wilder Lake sits 1 mi north — the closest neighbouring chart.
Come spring, look for brook trout tight to the bank in 1 to 7 ft. Through summer count on 2 to 7 ft; the winter hold is 1 to 7 ft. If you only fish one area, make it Deep basin: a deep basin around 6 ft that scores prime in summer. Best bite is early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 7 ft | dawn & dusk | Main-lake point (7 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 2 to 7 ft | dawn & dusk | Deep basin (6 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 1 to 7 ft | midday & dawn | Main-lake point (7 ft) | Small spoon (orange), Spinner |
| Winter | 1 to 7 ft | dawn | Deep basin (6 ft) | Small jigging spoon, Tungsten jig + plastic |
Count 3 structure marks on this chart. The deepest, Main-lake point, sits near 7 ft.
