23-acre lake in Sudbury District, Ontario. The lake tops out around 30 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. Here's the year, species by species, as the scoring engine sees it.
Drawn out, this is 23 acres of water rimmed by 1.2 miles of bank. The shoreline is moderately structured (index 1.7) — enough points and pockets to pattern. Roughly 47% 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 0.2 mi across at its widest. You'll find it in Sudbury District. For a second option, Ermatinger L. 50 lies 1 mi southeast.
Spring puts brook trout in skinny water — 2 to 15 ft is the zone. As the season builds they drop to 10 to 30 ft, wintering in 3 to 20 ft. Summer brook trout concentrate at Deep basin, a prime-rated deep basin around 26 ft. Warm-month bites cluster around early morning and the evening. 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 |
