159-acre lake in Cariboo Regional District, British Columbia. The lake tops out around 61 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. Below is the species-by-species picture, pulled from the same data the map uses.
Blue Lake maps at 159 acres behind 3.5 miles of shoreline. A middling shoreline index (2) gives it some bays to work without being a maze. 19% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. End to end it runs roughly 1.2 mi, about 0.5 mi across. Cariboo Regional District claims this one. If the bite dies, Tsetzi Lake is 2 mi to the southwest.
Come spring, look for rainbow trout tight to the bank in 5 to 20 ft. They move out to 8 to 30 ft in summer and finish the year down in 8 to 40 ft. If you only fish one area, make it Break off the point: a drop-off around 27 ft that scores prime in winter. Best bite is early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (15 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (27 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (15 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (27 ft) | Jigging spoon, Tube jig (white) |
Structure-wise the chart holds 6 features, led in depth by Deep basin at roughly 52 ft.
