38-acre lake in Cochrane District, Ontario. The lake tops out around 27 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. What follows comes from the same scoring engine that paints the spots above.
Drawn out, this is 37 acres of water rimmed by 1.3 miles of bank. The shoreline is moderately structured (index 1.5) — enough points and pockets to pattern. The shallow band under 15 ft claims about 74% of the surface — that's where the groceries are. Tip to tip the water measures near 0.5 mi with a 0.2-mi widest point. The water lies in Cochrane District. Closest neighbour on DepthScout: Daughter Lake, 1 mi west of here.
In spring, brook trout run shallow here, mostly 2 to 15 ft. Midsummer fish sit out in 8 to 27 ft before dropping to 3 to 20 ft for winter. Summer brook trout concentrate at Deep basin, a prime-rated deep basin around 20 ft. Fish it in early morning and the evening and you'll meet the bite. 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 (2 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 8 to 27 ft | dawn & dusk | Deep basin (20 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (2 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Deep basin (20 ft) | Small jigging spoon, Tungsten jig + plastic |
Start shallow in spring: northern pike sit in 2 to 8 ft that time of year. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 5 to 15 ft. The spot to know is Break off the point, a drop-off in about 7 ft of water that rates prime for northern pike in fall. Warm-month bites cluster around early morning and the evening. Throw a bucktail or a weedless spoon over cabbage until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (1 ft) | #5 inline spinner, Spoon (red/white) |

| Fall | 6 to 18 ft | midday & dawn | Break off the point (7 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Break off the point (7 ft) | Tip-ups, Large jigging spoon |
