68-acre lake in Algoma District, Ontario. The lake tops out around 53 ft. The depth data here comes from the Ontario MNRF survey of 1987 (a transect sounding survey). The rest of this page walks each species through its year, using the map's own scoring.
Long Lake maps at 68 acres behind 2.7 miles of shoreline. That shoreline is heavily fingered (development index 2.3) — bays, points and pockets everywhere, which multiplies the fishable edge. Roughly 25% of the water is 15 ft or less, the band where the food chain lives. Tip to tip the water measures near 1.1 mi with a 0.2-mi widest point. It sits in Algoma District. Spice Lake sits 1 mi southeast — the closest neighbouring chart.
Early season brook trout use the shallows, holding in 2 to 15 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 3 to 20 ft. Put Break off the point first on the milk run — a drop-off near 30 ft that grades prime for summer. In summer the feeding windows fall in 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 | Shallow bay flat (3 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (30 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | open water | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (3 ft) | Small jigging spoon, Tungsten jig + plastic |
