10-acre lake in British Columbia. The lake tops out around 57 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. Here is how the season plays out for each species, straight from the data behind the map.
Colborne Lake maps at 10 acres behind 0.6 miles of shoreline. Nearly circular (index 1.3), so the story is the bottom, not the bank. Roughly 16% of the water is 15 ft or less as modeled, the band where the food chain lives.
Spring rainbow trout on Colborne Lake hold shallow, usually 5 to 20 ft. By summer they slide out to 8 to 30 ft, and by winter most fish are in 8 to 40 ft. The chart's best answer is Shoreline break — drop-off, 26 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.

|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Shallow bay flat (6 ft) | Inline spinner (silver), Small spoon |
