190-acre lake in Bulkley-Nechako Regional District, British Columbia. The lake tops out around 20 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here is how the season plays out for each species, straight from the data behind the map.
The outline encloses 190 acres, worked by 2.3 miles of shoreline. At index 1.2 the outline is almost a bowl — read the depth changes, not the shoreline. 98% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Figure 0.9 mi of water from one end to the other, 0.5 mi at the beam. Bulkley-Nechako Regional District claims this one. If the bite dies, Cripple Lake is 5 mi to the northeast.
When the water first warms, rainbow trout slide up into 5 to 20 ft. There's no big seasonal slide here — summer means 5 to 20 ft, winter 4 to 20 ft. Start at Break off the point. It's a drop-off holding about 13 ft of water and rates prime come winter. The feeding windows run early morning and the evening. Keep a dodger + spoon (deep troll) or a flutter spoon rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Break off the point (13 ft) | Inline spinner (silver), Small spoon |
| Summer | 5 to 20 ft | dawn & dusk | Break off the point (13 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 6 to 20 ft | dawn & dusk | Break off the point (13 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 4 to 20 ft | dawn | Break off the point (13 ft) | Jigging spoon, Tube jig (white) |
In spring, lake whitefish run shallow here, mostly 6 to 20 ft. Summer keeps them at 6 to 20 ft, and they winter in 6 to 20 ft. Summer lake whitefish concentrate at Deep basin, a prime-rated deep basin around 19 ft. Fish it in early morning and you'll meet the bite. You won't need more than a blade bait vertical or a small jigging spoon most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 6 to 20 ft | midday & dawn | Break off the point (13 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 6 to 20 ft | dawn | Deep basin (19 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 5 to 20 ft | dusk | Break off the point (13 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 6 to 20 ft | midday & dawn | Deep basin (19 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Structure-wise the chart holds 6 features, led in depth by Deep basin at roughly 19 ft.
