Rating depth structure for rainbow trout.

1,506-acre lake in Bulkley-Nechako Regional District, British Columbia. The lake tops out around 157 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. Here's the year, species by species, as the scoring engine sees it.
The drawn water covers 1,506 acres wrapped in 12.3 miles of bank, broken up by 5 islands. The 2.3 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. The shallow band under 15 ft claims about 15% of the surface on the model — that's where the groceries are. End to end it runs roughly 4.5 mi, about 0.9 mi across. Bulkley-Nechako Regional District claims this one. If the bite dies, Nahlouza Lake is 9 mi to the east.
Come spring, look for rainbow trout tight to the bank in 5 to 20 ft. They move out to 8 to 30 ft in summer and finish the year down in 8 to 40 ft. If you only fish one area, make it Main-lake point: a point around 39 ft that scores prime in fall. Best bite is early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon is the honest summer answer here.
| 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 (39 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (71 ft) | Jigging spoon, Tube jig (white) |
Structure-wise the chart holds 6 features, led in depth by Deep basin at roughly 133 ft.
