Rating depth structure for rainbow trout.
Recent public catches load as you reach this section.
94-acre lake in Columbia-Shuswap Regional District, British Columbia. The lake tops out around 36 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The rest of this page walks each species through its year, using the map's own scoring.
On the chart, Nine Bay Lake draws 94 acres inside 3.4 miles of shoreline. A development index of 2.5 means a maze of bays and points: far more casting targets than a round bowl of the same size. Roughly 76% of the water is 15 ft or less, the band where the food chain lives. End to end it runs roughly 1 mi, about 0.4 mi across. You'll find it in Columbia-Shuswap Regional District. For a second option, Mitten Lake lies 2 mi northwest.
The spring pattern is a shallow one: rainbow trout in 5 to 20 ft. As the season builds they drop to 8 to 30 ft, wintering in 7 to 36 ft. Top water on the chart: Break off the point, a drop-off in the 15 ft range, prime in winter. Time it for early morning and the evening. Summer baits: a dodger + spoon (deep troll) or a flutter spoon gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Secondary point (7 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (15 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Break off the point (15 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 7 to 36 ft | dawn | Break off the point (15 ft) | Jigging spoon, Tube jig (white) |
