437-acre lake in Columbia-Shuswap Regional District, British Columbia. The lake tops out around 68 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.
Coursier Lake maps at 437 acres behind 5.7 miles of shoreline, broken up by an island. With a 2 development index there's bank structure worth casting at, in moderation. About 14% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. The basin spans about 2.1 mi end to end and 0.7 mi across at its widest. It sits in Columbia-Shuswap Regional District. Echo Lake sits 11 mi north — the closest neighbouring chart.
Spring rainbow trout on Coursier Lake hold shallow, usually 5 to 20 ft. By summer they slide out to 8 to 30 ft, and by winter most fish are in 8 to 40 ft. The chart's best answer is Break off the point — drop-off, 31 ft, prime for winter. Prime time lands in early morning and the evening. The summer box starts with a dodger + spoon (deep troll) or a flutter spoon.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (17 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (31 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (17 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (31 ft) | Jigging spoon, Tube jig (white) |
