64-acre lake in Bulkley-Nechako Regional District, British Columbia. The lake tops out around 20 ft. The depth chart comes from British Columbia Fish and Wildlife Branch bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What the data behind the map says about each species, season by season:
Traced from the shoreline, Division Lake runs 64 acres with 1.6 miles of edge, broken up by an island. The shoreline is moderately structured (index 1.5) — enough points and pockets to pattern. About 78% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The basin spans about 0.6 mi end to end and 0.2 mi across at its widest. The water lies in Bulkley-Nechako Regional District. The nearest mapped water is Pinkut Lake, 3 mi to the northeast.
In spring, rainbow trout run shallow here, mostly 5 to 20 ft. Summer keeps them at 5 to 20 ft, and they winter in 4 to 20 ft. Winter rainbow trout concentrate at Deep basin, a good-rated deep basin around 19 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.
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 | 5 to 20 ft | dawn & dusk | open water | Inline spinner (silver), Small spoon |
| Summer | 5 to 20 ft chart-limited; documented 8 to 30 ft | dawn & dusk | Deep basin (19 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 6 to 20 ft chart-limited; documented 10 to 35 ft | dawn & dusk | Deep basin (19 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 4 to 20 ft chart-limited; documented 8 to 40 ft | dawn | Deep basin (19 ft) | Jigging spoon, Tube jig (white) |
6 pieces of structure are mapped here — Deep basin, around 19 ft, is the deepest of them.
