51-acre lake in Bulkley-Nechako Regional District, British Columbia. The lake tops out around 38 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.
Nilan Lake maps at 51 acres behind 1.4 miles of shoreline. At index 1.4 the outline is almost a bowl — read the depth changes, not the shoreline. The shallow band under 15 ft claims about 76% of the surface — that's where the groceries are. Call it 0.5 mi long by 0.3 mi wide at the broadest reach. Bulkley-Nechako Regional District claims this one. If the bite dies, Karena Lake is 1 mi to the west.
Spring rainbow trout on Nilan Lake hold shallow, usually 5 to 20 ft. They move out to 8 to 30 ft in summer and finish the year down in 8 to 38 ft. Put Deep basin first on the milk run — a deep basin near 35 ft that grades prime for winter. The feeding windows run early morning and the evening. The summer box starts with a dodger + spoon (deep troll) or a flutter spoon.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (1 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (1 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Deep basin (35 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 38 ft | dawn | Deep basin (35 ft) | Jigging spoon, Tube jig (white) |
Structure-wise the chart holds 5 features, led in depth by Deep basin at roughly 35 ft.
