100-acre lake in British Columbia. The lake tops out around 35 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. What follows comes from the same scoring engine that paints the spots above.
On the chart, Dumbell Lake draws 100 acres inside 3 miles of shoreline. The shoreline is moderately structured (index 2.1) — enough points and pockets to pattern. 69% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water.
In spring, rainbow trout run shallow here, mostly 5 to 20 ft. Summer pushes them deeper, 8 to 30 ft, and winter fish settle into 7 to 35 ft. Break off the point is the standout, a drop-off at roughly 16 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.
| Season | Depth | Best window | Start at | Go-to baits |

| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (9 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (16 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (9 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 7 to 35 ft | dawn | Break off the point (16 ft) | Jigging spoon, Tube jig (white) |
