Rating depth structure for brook trout.

31-acre lake in Thunder Bay District, Ontario. The lake tops out around 19 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. The rest of this page walks each species through its year, using the map's own scoring.
The outline encloses 31 acres, worked by 1.3 miles of shoreline. With a 1.6 development index there's bank structure worth casting at, in moderation. About 91% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Figure 0.4 mi of water from one end to the other, 0.3 mi at the beam. It sits in Thunder Bay District. Miner Lake sits 0 mi north — the closest neighbouring chart.
Early season brook trout use the shallows, holding in 2 to 15 ft. Expect a summer slide to 6 to 19 ft, then a winter hold in 3 to 19 ft. Put Deep basin first on the milk run — a deep basin near 16 ft that grades prime for summer. In summer the feeding windows fall in 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 (8 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 6 to 19 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Deep basin (16 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (8 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 19 ft chart-limited; documented 3 to 20 ft | dawn | Deep basin (16 ft) | Small jigging spoon, Tungsten jig + plastic |
5 pieces of structure are mapped here — Deep basin, around 16 ft, is the deepest of them.
