78-acre lake in Peace River Regional District, British Columbia. The lake tops out around 71 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. The season-by-season read for each species follows, from the map's own numbers.
Traced from the shoreline, Simpson Lake runs 78 acres with 1.8 miles of edge. Index 1.5 on the shoreline: a few honest points and pockets, nothing labyrinthine. The shallow band under 15 ft claims about 32% of the surface on the model — that's where the groceries are. Figure 0.8 mi of water from one end to the other, 0.2 mi at the beam. The water lies in Peace River Regional District. The nearest mapped water is Doonan Lake, 2 mi to the northwest.
The spring pattern is a shallow one: rainbow trout in 5 to 20 ft. Midsummer fish sit out in 8 to 30 ft before dropping to 8 to 40 ft for winter. The spot to know is Break off the point, a drop-off in about 32 ft of water that rates prime for rainbow trout in winter. Plan around early morning and the evening in the warm months. Summer baits: a dodger + spoon (deep troll) or a flutter spoon gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (18 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (32 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (18 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (32 ft) | Jigging spoon, Tube jig (white) |
