462-acre lake in Cariboo Regional District, British Columbia. The lake tops out around 40 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. What the data behind the map says about each species, season by season:
The outline encloses 462 acres, worked by 3.8 miles of shoreline. Its 1.3 shoreline index means few bank features; the contours below do the pattern work. Roughly 58% of the water is 15 ft or less as modeled, the band where the food chain lives. Tip to tip the water measures near 1.4 mi with a 0.8-mi widest point. Cariboo Regional District claims this one. If the bite dies, Eagle Lake is 9 mi to the north.
When the water first warms, rainbow trout slide up into 5 to 20 ft. Summer is an 8 to 30 ft game here, winter an 8 to 40 ft one. Start at Break off the point. It's a drop-off holding about 18 ft of water and rates prime come winter. The feeding windows run early morning and the evening. Keep a dodger + spoon (deep troll) or a flutter spoon rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (10 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (18 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (10 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (18 ft) | Jigging spoon, Tube jig (white) |
Early season bull trout use the shallows, holding in 10 to 40 ft. Even in summer they hold at 12 to 40 ft; winter keeps them in 11 to 40 ft. The chart's best answer is Deep basin — deep basin, 34 ft, prime for summer. Best bite is early morning and the evening. Tie on a trolled plug on downrigger or a heavy jigging spoon and you're in the game.
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 | 10 to 40 ft | dawn & dusk | Break off the point (18 ft) | Large jointed plug, 6" swimbait (kokanee/trout pattern) |
| Summer | 12 to 40 ft chart-limited; documented 30 to 90 ft | dawn & dusk | Deep basin (34 ft) | Trolled plug on downrigger, Heavy jigging spoon |
| Fall | 5 to 35 ft | dawn & dusk | Main-lake point (10 ft) | Large glide bait, Jointed plug |
| Winter | 11 to 40 ft chart-limited; documented 20 to 70 ft | dawn | Break off the point (18 ft) | Heavy spoon (slow lift), Large soft swimbait |
Cochin Lake carries 6 mapped structure features, topping out (or rather bottoming out) at Deep basin, about 34 ft down.
