14-acre lake in Timiskaming District, Ontario. The lake tops out around 24 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. Species by species, here's what the data says the year looks like.
Traced from the shoreline, Ferguson Lake runs 13 acres with 0.9 miles of edge. Index 1.7 on the shoreline: a few honest points and pockets, nothing labyrinthine. Roughly 87% of the water is 15 ft or less as modeled, the band where the food chain lives. End to end it runs roughly 0.4 mi. You'll find it in Timiskaming District. The nearest mapped water is Emms Lake, 1 mi to the southeast.
Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Summer pushes them deeper, 7 to 24 ft, and winter fish settle into 3 to 20 ft. The spot to know is Deep basin, a deep basin in about 20 ft of water that rates prime for brook trout in summer. Warm-month bites cluster around early morning and the evening. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.
| 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 |
