63-acre lake in East Kootenay Regional District, British Columbia. The lake tops out around 79 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. The season-by-season read for each species follows, from the map's own numbers.
Drawn out, this is 63 acres of water rimmed by 1.5 miles of bank. At index 1.4 the outline is almost a bowl — read the depth changes, not the shoreline. 25% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Figure 0.6 mi of water from one end to the other, 0.3 mi at the beam. You'll find it in East Kootenay Regional District. For a second option, Sunburst Lake lies 0 mi east.
Spring cutthroat trout on Cerulean Lake hold shallow, usually 3 to 15 ft. By summer they slide out to 10 to 35 ft, and by winter most fish are in 10 to 40 ft. The chart's best answer is Break off the point — drop-off, 36 ft, prime for summer. Prime time lands in early morning and the evening. The summer box starts with a trolled spoon (small) or an inline spinner.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | Main-lake point (20 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 10 to 35 ft | dawn & dusk | Break off the point (36 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | Main-lake point (20 ft) | Casting spoon, Inline spinner |
| Winter | 10 to 40 ft | dawn | Break off the point (36 ft) | Small jigging spoon, Marabou jig |
Start shallow in spring: rainbow trout sit in 5 to 20 ft that time of year. Summer pushes them deeper, 8 to 30 ft, and winter fish settle into 8 to 40 ft. The spot to know is Break off the point, a drop-off in about 36 ft of water that rates prime for rainbow trout in winter. Warm-month bites cluster around early morning and the evening. Throw a dodger + spoon (deep troll) or a flutter spoon until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (20 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Main-lake point (20 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (20 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (36 ft) | Jigging spoon, Tube jig (white) |
Come spring, look for lake whitefish tight to the bank in 15 to 45 ft. They move out to 24 to 79 ft in summer and finish the year down in 25 to 70 ft. If you only fish one area, make it Deep basin: a deep basin around 67 ft that scores prime in summer. Best bite is early morning. A blade bait vertical or a small jigging spoon is the honest summer answer here.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Break off the point (36 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 24 to 79 ft chart-limited; documented 40 to 90 ft | dawn | Deep basin (67 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Main-lake point (20 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | Deep basin (67 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Structure-wise the chart holds 6 features, led in depth by Deep basin at roughly 67 ft.
