Rating depth structure for brook trout.

23-acre lake in Thunder Bay District, Ontario. The lake tops out around 18 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. Every species below gets its seasonal read from the same numbers driving the chart.
Gorge Lake maps at 23 acres behind 1.1 miles of shoreline. With a 1.6 development index there's bank structure worth casting at, in moderation. Roughly 69% of the water is 15 ft or less as modeled, the band where the food chain lives. Figure 0.4 mi of water from one end to the other, 0.2 mi at the beam. Thunder Bay District claims this one. Its nearest charted neighbour, Keemle Lake, is 4 mi to the southwest.
Early season brook trout use the shallows, holding in 2 to 15 ft. Summer is a 5 to 18 ft game here, winter a 3 to 18 ft one. The chart's best answer is Deep basin — deep basin, 15 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 (8 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 5 to 18 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Deep basin (15 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 18 ft chart-limited; documented 3 to 20 ft | dawn | Deep basin (15 ft) | Small jigging spoon, Tungsten jig + plastic |
