142-acre lake in Algoma District, Ontario. The lake tops out around 39 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. Here's the year, species by species, as the scoring engine sees it.
The outline encloses 143 acres, worked by 4.4 miles of shoreline. The 2.6 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. The shallow band under 15 ft claims about 65% of the surface on the model — that's where the groceries are. Figure 1.1 mi of water from one end to the other, 0.7 mi at the beam. Algoma District claims this one. Quinn Lake sits 3 mi southeast — the closest neighbouring chart.
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 Break off the point — drop-off, 18 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (10 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (18 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (10 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (18 ft) | Small jigging spoon, Tungsten jig + plastic |
