9-acre lake in Cochrane District, Ontario. The lake tops out around 25 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Below is the species-by-species picture, pulled from the same data the map uses.
Drawn out, this is 9 acres of water rimmed by 0.5 miles of bank. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. 61% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. You'll find it in Cochrane District. The nearest mapped water is Vinkle Lake, 3 mi to the southeast.
In spring, brook trout run shallow here, mostly 2 to 15 ft. Summer pushes them deeper, 8 to 25 ft, and winter fish settle into 3 to 20 ft. Deep basin is the standout, a deep basin at roughly 21 ft, rated prime for summer brook trout. Time it for early morning and the evening. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.
| 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 25 ft | dawn & dusk | Deep basin (21 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (8 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (11 ft) | Small jigging spoon, Tungsten jig + plastic |
Structure-wise the chart holds 3 features, led in depth by Deep basin at roughly 21 ft.
