Fishing Thomson Lake: what the data says
31-acre lake in British Columbia. The lake tops out around 71 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. The season-by-season read for each species follows, from the map's own numbers.
The drawn water covers 31 acres wrapped in 1 miles of bank. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. Roughly 20% of the water is 15 ft or less as modeled, the band where the food chain lives.
Rainbow Trout fishing at Thomson Lake
When the water first warms, rainbow trout slide up into 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. If you only fish one area, make it Break off the point: a drop-off around 32 ft that scores prime in winter. In summer the feeding windows fall in early morning and the evening. Keep a dodger + spoon (deep troll) or a flutter spoon rigged through the warm months.
| 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 |

Kokanee fishing at Thomson Lake
Come spring, look for kokanee tight to the bank in 10 to 30 ft. Expect a summer slide to 30 to 70 ft, then a winter hold in 18 to 71 ft. Start at Deep basin. It's a deep basin holding about 60 ft of water and rates prime come summer. Prime time lands in early morning. A dodger + pink/orange squid on downrigger or a kokanee bug + corn is the honest summer answer here.
