517-acre lake in Central Kootenay Regional District, British Columbia. The lake tops out around 312 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. Species by species, here's what the data says the year looks like.
Traced from the shoreline, Beatrice Lake runs 517 acres with 5.5 miles of edge, broken up by an island. Index 1.7 on the shoreline: a few honest points and pockets, nothing labyrinthine. Littoral water — the productive band under ~15 ft — makes up 3% of this chart, as modeled. Call it 2.3 mi long by 0.6 mi wide at the broadest reach. You'll find it in Central Kootenay Regional District. The nearest mapped water is Evans Lake, 3 mi to the southwest.
The spring pattern is a shallow one: rainbow trout in 5 to 20 ft. As the season builds they drop to 8 to 30 ft, wintering in 8 to 40 ft. Top water on the chart: Shallow bay flat, a feeding flat in the 6 ft range, good in spring. Time it for early morning and the evening. 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 | Shallow bay flat (6 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Shallow bay flat (6 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | open water | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (140 ft) | Jigging spoon, Tube jig (white) |
