72-acre lake in Central Kootenay Regional District, British Columbia. The lake tops out around 138 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. The rest of this page walks each species through its year, using the map's own scoring.
Traced from the shoreline, Catherine Lake runs 72 acres with 1.4 miles of edge. At index 1.2 the outline is almost a bowl — read the depth changes, not the shoreline. The shallow band under 15 ft claims about 12% of the surface on the model — that's where the groceries are. End to end it runs roughly 0.5 mi, about 0.3 mi across. The water lies in Central Kootenay Regional District. For a second option, Cameron Lake lies 6 mi south.
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 Main-lake point, a point in about 35 ft of water that rates prime for rainbow trout in fall. 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 | 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 | Main-lake point (35 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (62 ft) | Jigging spoon, Tube jig (white) |
