154-acre lake in North Okanagan Regional District, British Columbia. The lake tops out around 16 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. Species by species, here's what the data says the year looks like.
On the chart, Otter Lake draws 154 acres inside 2.8 miles of shoreline. Index 1.6 on the shoreline: a few honest points and pockets, nothing labyrinthine. 90% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. The basin spans about 1.2 mi end to end and 0.3 mi across at its widest. The water lies in North Okanagan Regional District. The nearest mapped water is Round Lake, 4 mi to the northwest.
The spring pattern is a shallow one: lake trout in 4 to 16 ft. The depth story barely changes: 5 to 16 ft through summer, 4 to 16 ft in winter. Top water on the chart: Deep basin, a deep basin in the 14 ft range, prime in summer. Time it for early morning. Summer baits: a white tube jig (deep) or a magnum spoon on downrigger gets it done.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 16 ft chart-limited; documented 10 to 40 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 5 to 16 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (14 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 3 to 16 ft chart-limited; documented 10 to 50 ft | dusk & dawn | Main-lake point (8 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 4 to 16 ft chart-limited; documented 20 to 80 ft | dawn | Deep basin (14 ft) | White tube jig, Airplane jig |
Start shallow in spring: rainbow trout sit in 4 to 16 ft that time of year. They don't go far with the seasons — 4 to 16 ft covers summer, 3 to 16 ft covers winter. Top water on the chart: Break off the point, a drop-off in the 7 ft range, prime in winter. Fish it in early morning and the evening and you'll meet the bite. Throw a dodger + spoon (deep troll) or a flutter spoon until the fish tell you otherwise.

| Season | Depth | Best window | Start at | Go-to baits |

| Spring | 4 to 16 ft chart-limited; documented 5 to 20 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 4 to 16 ft chart-limited; documented 8 to 30 ft | dawn & dusk | Break off the point (7 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 5 to 16 ft chart-limited; documented 10 to 35 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 3 to 16 ft chart-limited; documented 8 to 40 ft | dawn | Break off the point (7 ft) | Jigging spoon, Tube jig (white) |
