25-acre lake in Strathcona Regional District, British Columbia. The lake tops out around 34 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Every species below gets its seasonal read from the same numbers driving the chart.
On the chart, Martha Lake draws 25 acres inside 1.2 miles of shoreline. Index 1.7 on the shoreline: a few honest points and pockets, nothing labyrinthine. Littoral water — the productive band under ~15 ft — makes up 56% of this chart, as modeled. End to end it runs roughly 0.6 mi, about 0.2 mi across. You'll find it in Strathcona Regional District. For a second option, Paterson 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 34 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 | Main-lake point (9 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 34 ft | dawn & dusk | Main-lake point (9 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 7 to 34 ft | dawn | Break off the point (15 ft) | Jigging spoon, Tube jig (white) |
