62-acre lake in Thunder Bay District, Ontario. The lake tops out around 24 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. Every species below gets its seasonal read from the same numbers driving the chart.
The outline encloses 62 acres, worked by 3.1 miles of shoreline — 2 islands included. The 2.8 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. The shallow band under 15 ft claims about 82% of the surface — that's where the groceries are. Figure 1.1 mi of water from one end to the other, 0.3 mi at the beam. Thunder Bay District claims this one. Its nearest charted neighbour, Elbow Lake, is 1 mi to the south.
Early season brook trout use the shallows, holding in 2 to 15 ft. Summer is a 7 to 24 ft game here, winter a 3 to 20 ft one. The chart's best answer is Deep basin — deep basin, 21 ft, prime for summer. 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.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (5 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 7 to 24 ft chart-limited; documented 10 to 30 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 (5 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (7 ft) | Small jigging spoon, Tungsten jig + plastic |
