1,505-acre lake in Bulkley-Nechako Regional District, British Columbia. The lake tops out around 49 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. Below is the species-by-species picture, pulled from the same data the map uses.
The drawn water covers 1,505 acres wrapped in 7.4 miles of bank. A shoreline index of 1.4 says round and simple: fish relate to depth changes here, not shoreline features. Littoral water — the productive band under ~15 ft — makes up 24% of this chart, as modeled. The basin spans about 2 mi end to end and 1.7 mi across at its widest. It sits in Bulkley-Nechako Regional District. Its nearest charted neighbour, Oppy Lake, is 9 mi to the west.
When the water first warms, burbot slide up into 15 to 49 ft. There's no big seasonal slide here — summer means 15 to 49 ft, winter 12 to 49 ft. If you only fish one area, make it Deep basin: a deep basin around 42 ft that scores prime in spring. In summer the feeding windows fall in after dark and midday. Keep a heavy jig + cut bait rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 49 ft | night & dusk | Deep basin (42 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 15 to 49 ft | night & midday | Deep basin (42 ft) | Heavy jig + cut bait |
| Fall | 15 to 49 ft | night & dusk | Deep basin (42 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 12 to 49 ft | night & dusk | Deep basin (42 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
Spring rainbow trout on Nahlouza Lake hold shallow, usually 5 to 20 ft. By summer they slide out to 8 to 30 ft, and by winter most fish are in 8 to 40 ft. The chart's best answer is Break off the point — drop-off, 22 ft, prime for winter. Prime time lands in 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 (12 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (22 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (12 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (22 ft) | Jigging spoon, Tube jig (white) |
