27-acre lake in Cariboo Regional District, British Columbia. The lake tops out around 77 ft. The depth chart comes from British Columbia Fish and Wildlife Branch bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Species by species, here's what the data says the year looks like.
Traced from the shoreline, Crater Lake runs 27 acres with 0.8 miles of edge. A shoreline index of 1.1 says round and simple: fish relate to depth changes here, not shoreline features. Littoral water — the productive band under ~15 ft — makes up 32% of this chart. End to end it runs roughly 0.3 mi, about 0.2 mi across. You'll find it in Cariboo Regional District. The nearest mapped water is Marmot Lake, 7 mi to the northeast.
The spring pattern is a shallow one: rainbow trout in 5 to 20 ft. As the season builds they drop to 8 to 30 ft, wintering in 8 to 40 ft. Time it for early morning and the evening. Summer baits: a dodger + spoon (deep troll) or a flutter spoon gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | open water | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | open water | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | open water | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | open water | Jigging spoon, Tube jig (white) |
Structure-wise the chart holds 4 features, led in depth by Deep basin at roughly 77 ft.
