30-acre lake in Cochrane District, Ontario. The lake tops out around 66 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. What follows comes from the same scoring engine that paints the spots above.
The drawn water covers 29 acres wrapped in 1.4 miles of bank. With a 1.9 development index there's bank structure worth casting at, in moderation. The shallow band under 15 ft claims about 44% of the surface on the model — that's where the groceries are. The basin spans about 0.7 mi end to end. It sits in Cochrane District. Its nearest charted neighbour, Alexander Lake, is 0 mi to the west.
Spring brook trout on Grey Lake hold shallow, usually 2 to 15 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 3 to 20 ft. The chart's best answer is Break off the point — drop-off, 30 ft, prime for summer. Prime time lands in early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Shallow bay flat (6 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (30 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (17 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (6 ft) | Small jigging spoon, Tungsten jig + plastic |
Structure-wise the chart holds 5 features, led in depth by Deep basin at roughly 56 ft.
