508-acre lake in Stikine Region, British Columbia. The lake tops out around 75 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Every species below gets its seasonal read from the same numbers driving the chart.
Traced from the shoreline, Little Trapper Lake runs 508 acres with 4.5 miles of edge. Nearly circular (index 1.4), so the story is the bottom, not the bank. Littoral water — the productive band under ~15 ft — makes up 30% of this chart. Tip to tip the water measures near 1.4 mi with a 1-mi widest point. The water lies in Stikine Region. For a second option, Tatsatua Lake lies 8 mi east.
Spring puts lake trout in skinny water — 10 to 40 ft is the zone. As the season builds they drop to 23 to 75 ft, wintering in 19 to 75 ft. Summer lake trout concentrate at Deep basin, a prime-rated deep basin around 72 ft. Warm-month bites cluster around early morning. A white tube jig (deep) or a magnum spoon on downrigger covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Break off the point (7 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 23 to 75 ft | dawn | Deep basin (72 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Break off the point (7 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 19 to 75 ft | dawn | Deep basin (72 ft) | White tube jig, Airplane jig |
Spring puts rainbow trout in skinny water — 5 to 20 ft is the zone. Warm water sends them out to 8 to 30 ft; cold water stacks them in 8 to 40 ft. Break off the point is the standout, a drop-off at roughly 7 ft, rated prime for winter rainbow trout. Plan around early morning and the evening in the warm months. A dodger + spoon (deep troll) or a flutter spoon covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Break off the point (7 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (7 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Break off the point (7 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (7 ft) | Jigging spoon, Tube jig (white) |
