195-acre lake in Bulkley-Nechako Regional District, British Columbia. The lake tops out around 23 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. The rest of this page walks each species through its year, using the map's own scoring.
Triangle Lake maps at 195 acres behind 5.4 miles of shoreline. With a shoreline index of 2.7, this water is all arms and coves — edge habitat well beyond its acreage. 81% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Figure 1.7 mi of water from one end to the other, 0.6 mi at the beam. It sits in Bulkley-Nechako Regional District. Hallett Lake sits 1 mi northwest — the closest neighbouring chart.
Spring kokanee on Triangle Lake hold shallow, usually 7 to 23 ft. Depth-wise the year is flat: 7 to 23 ft in summer, 6 to 23 ft once it turns cold. The chart's best answer is Deep basin — deep basin, 20 ft, prime for spring. Prime time lands in early morning. The summer box starts with a dodger + pink/orange squid on downrigger or a kokanee bug + corn.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 7 to 23 ft | dawn | Deep basin (20 ft) | Small dodger + squid (pink), Wedding-ring spinner + corn |
| Summer | 7 to 23 ft | dawn | Deep basin (20 ft) | Dodger + pink/orange squid on downrigger, Kokanee bug + corn |
| Fall | 3 to 23 ft | dawn | Deep basin (20 ft) | Dodger + squid (deeper red/purple), Small spoon |
| Winter | 6 to 23 ft | dawn | Deep basin (20 ft) | Small glow jig + corn or maggot, Tiny spoon |
Early season rainbow trout use the shallows, holding in 5 to 20 ft. Expect a summer slide to 6 to 23 ft, then a winter hold in 5 to 23 ft. Put Break off the point first on the milk run — a drop-off near 10 ft that grades prime for winter. In summer the feeding windows fall in early morning and the evening. Tie on a dodger + spoon (deep troll) or a flutter spoon 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 (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 6 to 23 ft | dawn & dusk | Break off the point (10 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 7 to 23 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 5 to 23 ft | dawn | Break off the point (10 ft) | Jigging spoon, Tube jig (white) |
The spring pattern is a shallow one: lake whitefish in 7 to 23 ft. The depth story barely changes: 7 to 23 ft through summer, 7 to 23 ft in winter. Top water on the chart: Deep basin, a deep basin in the 20 ft range, prime in summer. Time it for early morning. Summer baits: a blade bait vertical or a small jigging spoon gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 7 to 23 ft | midday & dawn | Break off the point (10 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 7 to 23 ft | dawn | Deep basin (20 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 6 to 23 ft | dusk | Break off the point (10 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 7 to 23 ft | midday & dawn | Deep basin (20 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
