43-acre lake in Bulkley-Nechako Regional District, British Columbia. The lake tops out around 14 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. The season-by-season read for each species follows, from the map's own numbers.
Tandat Lake maps at 43 acres behind 1.9 miles of shoreline. A middling shoreline index (2) gives it some bays to work without being a maze. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. Call it 0.9 mi long. Bulkley-Nechako Regional District claims this one. Tseket Lake sits 1 mi northeast — the closest neighbouring chart.
When the water first warms, rainbow trout slide up into 4 to 14 ft. There's no big seasonal slide here — summer means 4 to 14 ft, winter 3 to 14 ft. Start at Break off the point. It's a drop-off holding about 6 ft of water and rates prime come winter. The feeding windows run early morning and the evening. Keep a dodger + spoon (deep troll) or a flutter spoon rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 14 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 4 to 14 ft | dawn & dusk | Break off the point (6 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 4 to 14 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 3 to 14 ft | dawn | Break off the point (6 ft) | Jigging spoon, Tube jig (white) |
Count 6 structure marks on this chart. The deepest, Deep basin, sits near 12 ft.
