1,090-acre lake in Stikine Region, British Columbia. The lake tops out around 138 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. Below is the species-by-species picture, pulled from the same data the map uses.
Drawn out, this is 1,090 acres of water rimmed by 7.8 miles of bank. Index 1.7 on the shoreline: a few honest points and pockets, nothing labyrinthine. Littoral water — the productive band under ~15 ft — makes up 4% of this chart, as modeled. The basin spans about 2.8 mi end to end and 1.2 mi across at its widest. The water lies in Stikine Region. For a second option, Hottah Lake lies 13 mi west.
The spring pattern is a shallow one: rainbow trout in 5 to 20 ft. Midsummer fish sit out in 8 to 30 ft before dropping to 8 to 40 ft for winter. The spot to know is Main-lake point, a point in about 35 ft of water that rates prime for rainbow trout in fall. Plan around early morning and the evening in the warm months. Summer baits: a dodger + spoon (deep troll) or a flutter spoon gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Shallow bay flat (6 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Shallow bay flat (6 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (35 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (62 ft) | Jigging spoon, Tube jig (white) |
When the water first warms, lake whitefish slide up into 15 to 45 ft. By summer they slide out to 40 to 90 ft, and by winter most fish are in 25 to 70 ft. If you only fish one area, make it Break off the point: a drop-off around 62 ft that scores prime in summer. In summer the feeding windows fall in early morning. Keep a blade bait vertical or a small jigging spoon rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Shallow bay flat (6 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 40 to 90 ft | dawn | Break off the point (62 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Main-lake point (35 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | Break off the point (62 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
