5-acre lake in British Columbia. The lake tops out around 15 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. What follows comes from the same scoring engine that paints the spots above.
Portal Lake maps at 5 acres behind 0.4 miles of shoreline. Nearly circular (index 1.4), so the story is the bottom, not the bank.
Spring rainbow trout on Portal Lake hold shallow, usually 4 to 15 ft. Even in summer they hold at 4 to 15 ft; winter keeps them in 3 to 15 ft. The chart's best answer is Break off the point — drop-off, 7 ft, prime for winter. Prime time lands in 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 | 4 to 15 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |

| Fall | 4 to 15 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 3 to 15 ft | dawn | Break off the point (7 ft) | Jigging spoon, Tube jig (white) |
