113-acre lake in Algoma District, Ontario. The lake tops out around 28 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. The rest of this page walks each species through its year, using the map's own scoring.
Traced from the shoreline, Mirror Lake runs 112 acres with 2.3 miles of edge. The shoreline is moderately structured (index 1.6) — enough points and pockets to pattern. Roughly 64% of the water is 15 ft or less as modeled, the band where the food chain lives. Tip to tip the water measures near 0.9 mi with a 0.4-mi widest point. The water lies in Algoma District. For a second option, Spook Lake lies 1 mi north.
Spring puts brook trout in skinny water — 2 to 15 ft is the zone. Warm water sends them out to 8 to 28 ft; cold water stacks them in 3 to 20 ft. Deep basin is the standout, a deep basin at roughly 24 ft, rated prime for summer brook trout. Plan around early morning and the evening in the warm months. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
| 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 | 8 to 28 ft | dawn & dusk | Deep basin (24 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 20 ft | dawn | Break off the point (13 ft) | Small jigging spoon, Tungsten jig + plastic |
In spring, lake trout run shallow here, mostly 7 to 28 ft. Summer keeps them at 8 to 28 ft, and they winter in 7 to 28 ft. Deep basin is the standout, a deep basin at roughly 24 ft, rated prime for summer lake trout. Time it for early morning. You won't need more than a white tube jig (deep) or a magnum spoon on downrigger most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
