41-acre lake in Cochrane District, Ontario. The lake tops out around 80 ft. 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 41 acres wrapped in 1.6 miles of bank, with 2 islands in the mix. With a 1.8 development index there's bank structure worth casting at, in moderation. The shallow band under 15 ft claims about 44% of the surface — that's where the groceries are. Call it 0.5 mi long by 0.3 mi wide at the broadest reach. Cochrane District claims this one. If the bite dies, Brown Lake is 1 mi to the northeast.
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. As the season builds they drop to 10 to 30 ft, wintering in 15 to 35 ft. Top water on the chart: Break off the point, a drop-off in the 23 ft range, prime in summer. Time it for early morning. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | open water | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (23 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (23 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Break off the point (23 ft) | Tungsten jig + spikes, Rattle spoon (small) |
