5-acre lake in Cochrane District, Ontario. The lake tops out around 13 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. Below is the species-by-species picture, pulled from the same data the map uses.
The outline encloses 4 acres, worked by 0.4 miles of shoreline. At index 1.2 the outline is almost a bowl — read the depth changes, not the shoreline. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. It sits in Cochrane District. Anrev Lake sits 0 mi northeast — the closest neighbouring chart.
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 4 to 13 ft before dropping to 4 to 13 ft for winter. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Fish it in early morning and you'll meet the bite. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 4 to 13 ft | dawn | Deep basin (11 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 4 to 13 ft | midday | Deep basin (11 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 4 to 13 ft | midday & dawn | Deep basin (11 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Early season northern pike use the shallows, holding in 2 to 8 ft. Summer is a 4 to 13 ft game here, winter a 4 to 13 ft one. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Best bite is early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 4 to 13 ft | dawn & dusk | Shoreline break (6 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 4 to 13 ft | midday & dawn | Shoreline break (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 4 to 13 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
Structure-wise the chart holds 3 features, led in depth by Deep basin at roughly 11 ft.
