138-acre lake in Algoma District, Ontario. The lake tops out around 20 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. 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.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft chart-limited; documented 10 to 40 ft | dawn & dusk | Main-lake point (5 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 6 to 20 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (20 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 4 to 20 ft chart-limited; documented 10 to 50 ft | dusk & dawn | Main-lake point (5 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 5 to 20 ft chart-limited; documented 20 to 80 ft | dawn | Deep basin (20 ft) | White tube jig, Airplane jig |
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.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Back-bay flat (4 ft) | Small jig + curly tail, Perch-pattern micro crank |

Spring smallmouth bass on Little Trout Lake hold shallow, usually 3 to 12 ft. By summer they slide out to 6 to 20 ft, and by winter most fish are in 6 to 20 ft. The chart's best answer is Secondary point — point, 9 ft, prime for fall. Prime time lands in early morning and the evening. The summer box starts with a drop shot (goby/minnow) or a ned rig.
