Fishing Big O.K. Lake: what the data says
98-acre lake in British Columbia. The lake tops out around 40 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. Below is the species-by-species picture, pulled from the same data the map uses.
The drawn water covers 98 acres wrapped in 2.2 miles of bank. A middling shoreline index (1.6) gives it some bays to work without being a maze. Roughly 52% of the water is 15 ft or less as modeled, the band where the food chain lives.
Rainbow Trout fishing at Big O.K. Lake
When the water first warms, rainbow trout slide up into 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. If you only fish one area, make it Break off the point: a drop-off around 18 ft that scores prime in winter. In summer the feeding windows fall in early morning and the evening. Keep a dodger + spoon (deep troll) or a flutter spoon rigged through the warm months.
