89-acre lake in Sudbury District, Ontario. The lake tops out around 40 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. Species by species, here's what the data says the year looks like.
The drawn water covers 90 acres wrapped in 1.7 miles of bank. Nearly circular (index 1.3), so the story is the bottom, not the bank. 17% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Tip to tip the water measures near 0.6 mi with a 0.4-mi widest point. Sudbury District claims this one. If the bite dies, Gough L. 5 is 1 mi to the south.
Early season brook trout use the shallows, holding in 2 to 15 ft. Summer is a 10 to 30 ft game here, winter a 3 to 20 ft one. The chart's best answer is Secondary point — point, 15 ft, prime for spring. Best bite is early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Secondary point (15 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (33 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
