14-acre lake in Algoma District, Ontario. The lake tops out around 54 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. Every species below gets its seasonal read from the same numbers driving the chart.
Lewis Lake maps at 14 acres behind 1 miles of shoreline. A middling shoreline index (2) gives it some bays to work without being a maze. Roughly 56% of the water is 15 ft or less as modeled, the band where the food chain lives. The basin spans about 0.5 mi end to end. It sits in Algoma District. Murphy Lake sits 0 mi northwest — the closest neighbouring chart.
Come spring, look for brook trout tight to the bank in 2 to 15 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 3 to 20 ft. Start at Break off the point. It's a drop-off holding about 24 ft of water and rates prime come summer. Prime time lands in early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (14 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (24 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (14 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (6 ft) | Small jigging spoon, Tungsten jig + plastic |
