1,258-acre lake in Fraser-Fort George Regional District, British Columbia. The lake tops out around 50 ft. The surface is reconstructed from 26 measured spot soundings collected in 1952; water between those measurements is interpolated. Treat the contours between those soundings as a guide, never as navigation. The rest of this page walks each species through its year, using the map's own scoring.
On the chart, Nadsilnich Lake draws 1,258 acres inside 7.3 miles of shoreline. The shoreline is moderately structured (index 1.5) — enough points and pockets to pattern. The shallow band under 15 ft claims about 20% of the surface on the model — that's where the groceries are. Call it 2.7 mi long by 1.3 mi wide at the broadest reach. The water lies in Fraser-Fort George Regional District. The nearest mapped water is Fyfe Lake, 3 mi to the east.
In spring, burbot run shallow here, mostly 15 to 50 ft. Summer keeps them at 15 to 50 ft, and they winter in 13 to 50 ft. Deep basin is the standout, a deep basin at roughly 41 ft, rated prime for spring burbot. Time it for after dark and midday. You won't need more than a heavy jig + cut bait most summer days.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 50 ft chart-limited; documented 25 to 70 ft | night & dusk | Deep basin (41 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 15 to 50 ft chart-limited; documented 50 to 120 ft | night & midday | Deep basin (41 ft) | Heavy jig + cut bait |
| Fall | 15 to 50 ft chart-limited; documented 30 to 80 ft | night & dusk | Deep basin (41 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 13 to 50 ft chart-limited; documented 15 to 60 ft | night & dusk | Deep basin (41 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
Spring puts kokanee in skinny water — 10 to 30 ft is the zone. Warm water sends them out to 15 to 50 ft; cold water stacks them in 13 to 50 ft. Deep basin is the standout, a deep basin at roughly 41 ft, rated prime for summer kokanee. Plan around early morning in the warm months. A dodger + pink/orange squid on downrigger or a kokanee bug + corn covers the summer program.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 30 ft | dawn | Break off the point (32 ft) | Small dodger + squid (pink), Wedding-ring spinner + corn |
| Summer | 15 to 50 ft chart-limited; documented 30 to 70 ft | dawn | Deep basin (41 ft) | Dodger + pink/orange squid on downrigger, Kokanee bug + corn |
| Fall | 5 to 40 ft | dawn | Deep basin (41 ft) | Dodger + squid (deeper red/purple), Small spoon |
| Winter | 13 to 50 ft chart-limited; documented 20 to 80 ft | dawn | Deep basin (41 ft) | Small glow jig + corn or maggot, Tiny spoon |
In spring, rainbow trout run shallow here, mostly 5 to 20 ft. Midsummer fish sit out in 8 to 30 ft before dropping to 8 to 40 ft for winter. Winter rainbow trout concentrate at Break off the point, a prime-rated drop-off around 32 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a dodger + spoon (deep troll) or a flutter spoon most summer days.
| 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 (32 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Break off the point (32 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (32 ft) | Jigging spoon, Tube jig (white) |
Spring lake whitefish on Nadsilnich Lake hold shallow, usually 15 to 45 ft. By summer they slide out to 15 to 50 ft, and by winter most fish are in 15 to 50 ft. The chart's best answer is Deep basin — deep basin, 41 ft, prime for summer. Prime time lands in early morning. The summer box starts with a blade bait vertical or a small jigging spoon.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Break off the point (32 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 15 to 50 ft chart-limited; documented 40 to 90 ft | dawn | Deep basin (41 ft) | Blade bait vertical, Small jigging spoon |

| Winter | 15 to 50 ft chart-limited; documented 25 to 70 ft | midday & dawn | Deep basin (41 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
When the water first warms, dolly varden slide up into 1 to 30 ft. By summer they slide out to 2 to 40 ft, and by winter most fish are in 8 to 45 ft. If you only fish one area, make it Main-lake point: a point around 1 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Keep a small chrome spoon or a baitfish streamer rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 30 ft | dawn & midday | Main-lake point (1 ft) | Small silver spoon, Inline spinner |
| Summer | 2 to 40 ft | dawn & dusk | Main-lake point (1 ft) | Small chrome spoon, Baitfish streamer |
| Fall | 1 to 25 ft | dawn & dusk | Main-lake point (1 ft) | Small spinner, Egg or fry pattern |
| Winter | 8 to 45 ft | midday | Break off the point (32 ft) | Small slow spoon, Weighted baitfish fly |
