5,456-acre lake in Bulkley-Nechako Regional District, British Columbia. The lake tops out around 25 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Below is the species-by-species picture, pulled from the same data the map uses.
Traced from the shoreline, Tachick Lake runs 5,238 acres with 18.1 miles of edge. The shoreline is moderately structured (index 1.8) — enough points and pockets to pattern. 71% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. The basin spans about 7.3 mi end to end and 1.9 mi across at its widest. You'll find it in Bulkley-Nechako Regional District. The nearest mapped water is Nulki Lake, 3 mi to the southeast.
In spring, rainbow trout run shallow here, mostly 5 to 20 ft. Summer pushes them deeper, 7 to 25 ft, and winter fish settle into 5 to 25 ft. Creek inflow is the standout, an inflow / creek mouth at roughly 4 ft, rated prime for spring rainbow trout. Time it for early morning and the evening. 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 | Creek inflow (4 ft) | Inline spinner (silver), Small spoon |
| Summer | 7 to 25 ft | dawn & dusk | Old creek channel (13 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 7 to 25 ft | dawn & dusk | Gravel shoal (5 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 5 to 25 ft | dawn | Break off the point (11 ft) | Jigging spoon, Tube jig (white) |
Spring lake whitefish on Tachick Lake hold shallow, usually 8 to 25 ft. Depth-wise the year is flat: 8 to 25 ft in summer, 8 to 25 ft once it turns cold. Put Deep basin first on the milk run — a deep basin near 21 ft that grades prime for summer. The feeding windows run 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 | 8 to 25 ft | midday & dawn | Break off the point (11 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 8 to 25 ft | dawn | Deep basin (21 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 7 to 25 ft | dusk | Gravel shoal (5 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 8 to 25 ft | midday & dawn | Deep basin (21 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
