375-acre lake in Bulkley-Nechako Regional District, British Columbia. The lake tops out around 62 ft. The surface is reconstructed from 35 measured spot soundings collected in 1985; water between those measurements is interpolated. Treat the contours between those soundings as a guide, never as navigation. Every species below gets its seasonal read from the same numbers driving the chart.
Drawn out, this is 375 acres of water rimmed by 5.3 miles of bank. Index 2 on the shoreline: a few honest points and pockets, nothing labyrinthine. The shallow band under 15 ft claims about 20% of the surface on the model — that's where the groceries are. End to end it runs roughly 2.2 mi, about 0.5 mi across. The water lies in Bulkley-Nechako Regional District. The nearest mapped water is Laidman Lake, 10 mi to the southwest.
Start shallow in spring: rainbow trout sit in 5 to 20 ft that time of year. Warm water sends them out to 8 to 30 ft; cold water stacks them in 8 to 40 ft. Top water on the chart: Break off the point, a drop-off in the 48 ft range, good in winter. Fish it in early morning and the evening and you'll meet the bite. 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 | Main-lake point (1 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | open water | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (1 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (48 ft) | Jigging spoon, Tube jig (white) |
Come spring, look for lake whitefish tight to the bank in 15 to 45 ft. Expect a summer slide to 19 to 62.34 ft, then a winter hold in 19 to 62.34 ft. Start at Deep basin. It's a deep basin holding about 52 ft of water and rates prime come summer. Prime time lands in early morning. A blade bait vertical or a small jigging spoon is the honest summer answer here.
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 45 ft | midday & dawn | Break off the point (48 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 19 to 62.34 ft chart-limited; documented 40 to 90 ft | dawn | Deep basin (52 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | open water | Small spoon (gold), Jig + plastic larva |
| Winter | 19 to 62.34 ft chart-limited; documented 25 to 70 ft | midday & dawn | Deep basin (52 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
The chart marks 6 structure features on Top Lake; the deepest is Deep basin at about 52 ft.

Top Lake is about 62.34 ft (19 m) deep at its deepest point. The surface is reconstructed from 35 measured spot soundings collected in 1985; water between those measurements is interpolated. Treat the contours between those soundings as a guide, never as navigation.
