Rating depth structure for rainbow trout.

170-acre lake in Comox Valley Regional District, British Columbia. The lake tops out around 133 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. The season-by-season read for each species follows, from the map's own numbers.
The drawn water covers 170 acres wrapped in 3.1 miles of bank. With a 1.7 development index there's bank structure worth casting at, in moderation. About 14% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Figure 1 mi of water from one end to the other, 0.6 mi at the beam. Comox Valley Regional District claims this one. If the bite dies, Lady Lake is 1 mi to the southeast.
Spring rainbow trout on Lake Helen Mackenzie hold shallow, usually 5 to 20 ft. They move out to 8 to 30 ft in summer and finish the year down in 8 to 40 ft. Put Main-lake point first on the milk run — a point near 33 ft that grades prime for fall. The feeding windows run early morning and the evening. The summer box starts with a dodger + spoon (deep troll) or a flutter spoon.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Shallow bay flat (6 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Main-lake point (33 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (33 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (60 ft) | Jigging spoon, Tube jig (white) |
Structure-wise the chart holds 6 features, led in depth by Deep basin at roughly 113 ft.
