146-acre lake in Bulkley-Nechako Regional District, British Columbia. The lake tops out around 16 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Every species below gets its seasonal read from the same numbers driving the chart.
Traced from the shoreline, Nellian Lake runs 146 acres with 2.8 miles of edge. The shoreline is moderately structured (index 1.7) — enough points and pockets to pattern. The basin spans about 1.3 mi end to end and 0.3 mi across at its widest. You'll find it in Bulkley-Nechako Regional District. The nearest mapped water is Division Lake, 4 mi to the southeast.
In spring, rainbow trout run shallow here, mostly 4 to 16 ft. Summer keeps them at 4 to 16 ft, and they winter in 3 to 16 ft. Break off the point is the standout, a drop-off at roughly 7 ft, rated prime for winter 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.
