138-acre lake in Algoma District, Ontario. The lake tops out around 20 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. Every species below gets its seasonal read from the same numbers driving the chart.
Little Trout Lake maps at 139 acres behind 2.6 miles of shoreline, with a single island in the mix. A middling shoreline index (1.6) gives it some bays to work without being a maze. The shallow band under 15 ft claims about 59% of the surface — that's where the groceries are. Tip to tip the water measures near 1 mi with a 0.3-mi widest point. Algoma District claims this one. Its nearest charted neighbour, Big Trout L., is 2 mi to the north.
Early season lake trout use the shallows, holding in 5 to 20 ft. Even in summer they hold at 6 to 20 ft; winter keeps them in 5 to 20 ft. The chart's best answer is Deep basin — deep basin, 20 ft, prime for summer. Best bite is early morning. Tie on a white tube jig (deep) or a magnum spoon on downrigger and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (5 ft) | Casting spoon over shoals, Jerkbait (shallow) |

Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 6 to 20 ft, wintering in 6 to 20 ft. Spring yellow perch concentrate at Back-bay flat, a prime-rated weed flat around 4 ft. Warm-month bites cluster around early morning. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.

|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Back-bay flat (4 ft) | Small jig + curly tail, Perch-pattern micro crank |
