Rating depth structure for rainbow trout.

182-acre lake in Cariboo Regional District, British Columbia. The lake tops out around 56 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. Below is the species-by-species picture, pulled from the same data the map uses.
Rainbow Lake maps at 182 acres behind 4.2 miles of shoreline. That shoreline is heavily fingered (development index 2.2) — bays, points and pockets everywhere, which multiplies the fishable edge. Roughly 26% of the water is 15 ft or less as modeled, the band where the food chain lives. Tip to tip the water measures near 1.5 mi with a 0.4-mi widest point. It sits in Cariboo Regional District. Its nearest charted neighbour, Stump Lake, is 5 mi to the south.
When the water first warms, kokanee slide up into 10 to 30 ft. By summer they slide out to 17 to 56 ft, and by winter most fish are in 14 to 56 ft. If you only fish one area, make it Deep basin: a deep basin around 48 ft that scores prime in summer. In summer the feeding windows fall in early morning. Keep a dodger + pink/orange squid on downrigger or a kokanee bug + corn rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 30 ft | dawn | Break off the point (25 ft) | Small dodger + squid (pink), Wedding-ring spinner + corn |
| Summer | 17 to 56 ft | dawn | Deep basin (48 ft) | Dodger + pink/orange squid on downrigger, Kokanee bug + corn |
| Fall | 5 to 40 ft | dawn | Break off the point (25 ft) | Dodger + squid (deeper red/purple), Small spoon |
| Winter | 14 to 56 ft | dawn | Deep basin (48 ft) | Small glow jig + corn or maggot, Tiny spoon |
Come spring, look for rainbow trout tight to the bank in 5 to 20 ft. Expect a summer slide to 8 to 30 ft, then a winter hold in 8 to 40 ft. Start at Break off the point. It's a drop-off holding about 25 ft of water and rates prime come winter. Prime time lands in early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (14 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (25 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (14 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (25 ft) | Jigging spoon, Tube jig (white) |
Spring puts lake whitefish in skinny water — 15 to 45 ft is the zone. As the season builds they drop to 17 to 56 ft, wintering in 17 to 56 ft. Summer lake whitefish concentrate at Deep basin, a prime-rated deep basin around 48 ft. Warm-month bites cluster around early morning. A blade bait vertical or a small jigging spoon covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Break off the point (25 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 17 to 56 ft | dawn | Deep basin (48 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (25 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 17 to 56 ft | midday & dawn | Deep basin (48 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |

Anglers target kokanee, rainbow trout, lake whitefish on Rainbow Lake.
Deep basin is the top-rated area: a deep basin in about 48 ft of water that rates prime for kokanee in summer. Every other rated spot, per species and season, is on the map above.
For kokanee, the summer bite is best in early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
