11-acre lake in East Kootenay Regional District, British Columbia. The lake tops out around 18 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. Species by species, here's what the data says the year looks like.
Blue Bottom Lake maps at 11 acres behind 0.6 miles of shoreline. At index 1.2 the outline is almost a bowl — read the depth changes, not the shoreline. The shallow band under 15 ft claims about 89% of the surface on the model — that's where the groceries are. East Kootenay Regional District claims this one. Its nearest charted neighbour, Surveyors Lake, is 2 mi to the south.
Early season brook trout use the shallows, holding in 2 to 15 ft. Summer is a 5 to 18 ft game here, winter a 3 to 18 ft one. The chart's best answer is Deep basin — deep basin, 15 ft, prime for summer. Best bite is early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.
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 | 2 to 15 ft | dawn & dusk | Main-lake point (8 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 5 to 18 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Deep basin (15 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (8 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 18 ft chart-limited; documented 3 to 20 ft | dawn | Deep basin (15 ft) | Small jigging spoon, Tungsten jig + plastic |
Come spring, look for largemouth bass tight to the bank in 2 to 10 ft. Expect a summer slide to 5 to 18 ft, then a winter hold in 5 to 18 ft. Start at Main-lake point. It's a point holding about 8 ft of water and rates prime come fall. Prime time lands in early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait 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 | 2 to 10 ft | dawn & dusk | Main-lake point (8 ft) | Spinnerbait, Chatterbait |
| Summer | 5 to 18 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Break off the point (8 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (8 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 5 to 18 ft chart-limited; documented 15 to 35 ft | midday | Break off the point (8 ft) | Blade bait, Jigging spoon |
Structure-wise the chart holds 3 features, led in depth by Deep basin at roughly 15 ft.

Main-lake point is the top-rated area: a point in about 8 ft of water that rates prime for largemouth bass in fall. Every other rated spot, per species and season, is on the map above.
For brook trout, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
