41-acre lake in Algoma District, Ontario. The lake tops out around 79 ft. The depth data here comes from the Ontario MNRF survey of 1964, a decades-old survey (a transect sounding survey). Every species below gets its seasonal read from the same numbers driving the chart.
On the chart, Long Lake draws 41 acres inside 1.9 miles of shoreline, broken up by an island. The shoreline is moderately structured (index 2.1) — enough points and pockets to pattern. The shallow band under 15 ft claims about 21% of the surface — that's where the groceries are. End to end it runs roughly 0.8 mi, about 0.2 mi across. You'll find it in Algoma District. For a second option, Mud Lake lies 1 mi west.
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. Spring brook trout concentrate at Main-lake point, a prime-rated point around 5 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 (5 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | open water | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (5 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (4 ft) | Small jigging spoon, Tungsten jig + plastic |
