Rating depth structure for brook trout.

27-acre lake in Algoma District, Ontario. The lake tops out around 80 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 the Ontario MNRF survey of 1962, a decades-old survey (a transect sounding survey). The rest of this page walks each species through its year, using the map's own scoring.
The outline encloses 26 acres, worked by 1.3 miles of shoreline. A middling shoreline index (1.9) gives it some bays to work without being a maze. The shallow band under 15 ft claims about 54% of the surface — that's where the groceries are. Call it 0.4 mi long by 0.3 mi wide at the broadest reach. Algoma District claims this one. Squawk L. sits 0 mi southeast — the closest neighbouring chart.
When the water first warms, brook trout slide up into 2 to 15 ft. Summer is a 10 to 30 ft game here, winter a 3 to 20 ft one. Start at Main-lake point. It's a point holding about 6 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a small spoon fished deep or a trolled lake-clear wobbler + worm rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (6 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (7 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (6 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (7 ft) | Small jigging spoon, Tungsten jig + plastic |
