81-acre lake in Strathcona Regional District, British Columbia. The lake tops out around 61 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here is how the season plays out for each species, straight from the data behind the map.
Tlowils Lake maps at 81 acres behind 2.1 miles of shoreline. A middling shoreline index (1.7) gives it some bays to work without being a maze. Littoral water — the productive band under ~15 ft — makes up 54% of this chart. Tip to tip the water measures near 1 mi with a 0.2-mi widest point. It sits in Strathcona Regional District. Its nearest charted neighbour, Santa Maria Lake, is 3 mi to the northeast.
The spring pattern is a shallow one: cutthroat trout in 3 to 15 ft. Midsummer fish sit out in 10 to 35 ft before dropping to 10 to 40 ft for winter. The spot to know is Break off the point, a drop-off in about 23 ft of water that rates prime for cutthroat trout in summer. Plan around early morning and the evening in the warm months. Summer baits: a trolled spoon (small) or an inline spinner gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | Main-lake point (1 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 10 to 35 ft | dawn & dusk | Break off the point (23 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | Break off the point (23 ft) | Casting spoon, Inline spinner |
| Winter | 10 to 40 ft | dawn | Break off the point (23 ft) | Small jigging spoon, Marabou jig |
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 23 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 (1 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (23 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Break off the point (23 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (23 ft) | Jigging spoon, Tube jig (white) |
