Rating depth structure for rainbow trout.

11-acre lake in Nanaimo Regional District, British Columbia. The lake tops out around 12 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. Here is how the season plays out for each species, straight from the data behind the map.
Cathers Lake maps at 11 acres behind 0.9 miles of shoreline. A middling shoreline index (1.8) gives it some bays to work without being a maze. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. The basin spans about 0.4 mi end to end. It sits in Nanaimo Regional District. Its nearest charted neighbour, Westwood Lake, is 1 mi to the southwest.
Come spring, look for rainbow trout tight to the bank in 3 to 12 ft. Through summer count on 3 to 12 ft; the winter hold is 2 to 12 ft. Start at Break off the point. It's a drop-off holding about 5 ft of water and rates prime come winter. Prime time lands in early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 3 to 12 ft | dawn & dusk | Break off the point (5 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 3 to 12 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 2 to 12 ft | dawn | Break off the point (5 ft) | Jigging spoon, Tube jig (white) |
