17-acre lake in Cochrane District, Ontario. The lake tops out around 57 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The depth data here comes from a transect sounding survey by the Ontario MNRF. Here is how the season plays out for each species, straight from the data behind the map.
The drawn water covers 17 acres wrapped in 0.9 miles of bank. With a 1.5 development index there's bank structure worth casting at, in moderation. About 32% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The basin spans about 0.3 mi end to end. Cochrane District claims this one. If the bite dies, Smith Lake is 0 mi to the east.
Early season brook trout use the shallows, holding in 2 to 15 ft. Summer is a 10 to 30 ft game here, winter a 3 to 20 ft one. The chart's best answer is Main-lake point — point, 18 ft, good for spring. Best bite is early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (18 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | open water | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (18 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | open water | Small jigging spoon, Tungsten jig + plastic |
