16,297-acre lake in Cariboo Regional District, British Columbia. The lake tops out around 331 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. Every species below gets its seasonal read from the same numbers driving the chart.
Charlotte Lake maps at 16,297 acres behind 36.1 miles of shoreline, broken up by 7 islands. A middling shoreline index (2) gives it some bays to work without being a maze. 5% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. The basin spans about 9.7 mi end to end and 4.9 mi across at its widest. It sits in Cariboo Regional District. Its nearest charted neighbour, Cowboy Lakes, is 5 mi to the south.
Come spring, look for rainbow trout tight to the bank in 5 to 20 ft. Expect a summer slide to 8 to 30 ft, then a winter hold in 8 to 40 ft. Start at Sharp break. It's a drop-off holding about 35 ft of water and rates prime come winter. Prime time lands in 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 | Shallow bay flat (6 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Sharp break (35 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Sharp break (35 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Sharp break (35 ft) | Jigging spoon, Tube jig (white) |
Charlotte Lake carries 10 mapped structure features, topping out (or rather bottoming out) at Deep basin, about 281 ft down.
