31-acre lake in Algoma District, Ontario. The lake tops out around 42 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. Species by species, here's what the data says the year looks like.
Coppens Lake maps at 31 acres behind 1.4 miles of shoreline. A middling shoreline index (1.8) gives it some bays to work without being a maze. Roughly 48% of the water is 15 ft or less as modeled, the band where the food chain lives. The basin spans about 0.4 mi end to end and 0.3 mi across at its widest. It sits in Algoma District. Its nearest charted neighbour, Eileen Lake, is 1 mi to the southwest.
When the water first warms, brook trout slide up into 2 to 15 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 3 to 20 ft. If you only fish one area, make it Break off the point: a drop-off around 19 ft that scores prime in summer. In summer the feeding windows fall in 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 (11 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (19 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
