508-acre lake in Stikine Region, British Columbia. The lake tops out around 75 ft. The depth chart comes from British Columbia Fish and Wildlife Branch 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.
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 | 10 to 40 ft | dawn & dusk | Break off the point (7 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 23 to 75 ft chart-limited; documented 50 to 120 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 chart-limited; documented 20 to 80 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 good 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) |
In spring, chinook salmon run shallow here, mostly 5 to 40 ft. Summer pushes them deeper, 23 to 75 ft, and winter fish settle into 23 to 75 ft. Deep basin is the standout, a deep basin at roughly 72 ft, rated prime for summer chinook salmon. Time it for early morning and the evening. You won't need more than a flasher + fly (green/white) or a magnum spoon on downrigger most summer days.
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 40 ft | dawn & dusk | Break off the point (7 ft) | Trolled spoon (orange/gold), Stickbait off planer boards |
| Summer | 23 to 75 ft chart-limited; documented 50 to 120 ft | dawn & dusk | Deep basin (72 ft) | Flasher + fly (green/white), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dawn & dusk | Break off the point (7 ft) | J-plug (glow), Flasher + fly |
| Winter | 23 to 75 ft chart-limited; documented 30 to 90 ft | midday | Deep basin (72 ft) | Small spoon on a slow troll, Stickbait deep |
The spring pattern is a shallow one: coho salmon in 3 to 25 ft. As the season builds they drop to 30 to 70 ft, wintering in 20 to 60 ft. Top water on the chart: Deep basin, a deep basin in the 72 ft range, good in summer. Time it for early morning and the evening. Summer baits: a dodger + fly or a medium spoon above the thermocline gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Break off the point (7 ft) | Small orange dodger + peanut fly, Thin spoon (orange/silver) |
| Summer | 30 to 70 ft | dawn & dusk | Deep basin (72 ft) | Dodger + fly, Medium spoon above the thermocline |
| Fall | 8 to 40 ft | dawn & dusk | Break off the point (7 ft) | Casting spoon, Spinner (chartreuse) |
| Winter | 20 to 60 ft | midday | Deep basin (72 ft) | Small spoon, slow troll |
Come spring, look for dolly varden tight to the bank in 1 to 30 ft. Expect a summer slide to 2 to 40 ft, then a winter hold in 8 to 45 ft. Start at Main-lake point. It's a point holding about 1 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A small chrome spoon or a baitfish streamer is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 30 ft | dawn & midday | Main-lake point (1 ft) | Small silver spoon, Inline spinner |
| Summer | 2 to 40 ft | dawn & dusk | Main-lake point (1 ft) | Small chrome spoon, Baitfish streamer |
| Fall | 1 to 25 ft | dawn & dusk | Main-lake point (1 ft) | Small spinner, Egg or fry pattern |
| Winter | 8 to 45 ft | midday | Break off the point (7 ft) | Small slow spoon, Weighted baitfish fly |
When the water first warms, steelhead slide up into 3 to 20 ft. Summer is a 5 to 45 ft game here, winter a 4 to 15 ft one. Start at Break off the point. It's a drop-off holding about 7 ft of water and rates prime come summer. The feeding windows run early morning and the evening. Keep an orange dodger + fly high in the column or a thin spoon off boards rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 20 ft | dawn & dusk | Break off the point (7 ft) | Small spoon or spinner at the mouths, Jig + waxworm under float |
| Summer | 5 to 45 ft | dawn & dusk | Break off the point (7 ft) | Orange dodger + fly high in the column, Thin spoon off boards |
| Fall | 5 to 30 ft | dawn & dusk | Break off the point (7 ft) | Spinner (silver/blue), Casting spoon |
| Winter | 4 to 15 ft | midday | open water | Float jig (black/purple), Bead rig |
