1,925-acre lake in Bulkley-Nechako Regional District, British Columbia. The lake tops out around 105 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Here's the year, species by species, as the scoring engine sees it.
Traced from the shoreline, Blanchet Lake runs 1,925 acres with 22.5 miles of edge, broken up by 5 islands. A development index of 3.7 means a maze of bays and points: far more casting targets than a round bowl of the same size. Roughly 60% of the water is 15 ft or less as modeled, the band where the food chain lives. Figure 7 mi of water from one end to the other, 1.6 mi at the beam. You'll find it in Bulkley-Nechako Regional District. The nearest mapped water is Eutsuk Lake, 13 mi to the west.
Start shallow in spring: rainbow trout sit in 5 to 20 ft that time of year. Summer pushes them deeper, 8 to 30 ft, and winter fish settle into 8 to 40 ft. The spot to know is Main-lake point, a point in about 26 ft of water that rates prime for rainbow trout in fall. Warm-month bites cluster around early morning and the evening. Throw a dodger + spoon (deep troll) or a flutter spoon until the fish tell you otherwise.
| 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 | Main-lake point (26 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (26 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | open water | Jigging spoon, Tube jig (white) |
