Rating depth structure for cutthroat trout.
Recent public catches load as you reach this section.
76-acre lake in British Columbia. The lake tops out around 69 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. Here's the year, species by species, as the scoring engine sees it.
Alvin Lake maps at 76 acres behind 2 miles of shoreline. A middling shoreline index (1.7) gives it some bays to work without being a maze. About 41% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. The basin spans about 0.7 mi end to end and 0.3 mi across at its widest. It sits in Skeena-Queen Charlotte Regional District. Its nearest charted neighbour, Kumealon Lake, is 6 mi to the northwest.
The spring pattern is a shallow one: cutthroat trout in 3 to 15 ft. Midsummer fish sit out in 10 to 35 ft before dropping to 10 to 40 ft for winter. The spot to know is Break off the point, a drop-off in about 31 ft of water that rates prime for cutthroat trout in summer. Plan around early morning and the evening in the warm months. Summer baits: a trolled spoon (small) or an inline spinner gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | Main-lake point (17 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 10 to 35 ft | dawn & dusk | Break off the point (31 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | Main-lake point (17 ft) | Casting spoon, Inline spinner |
| Winter | 10 to 40 ft | dawn | Break off the point (31 ft) | Small jigging spoon, Marabou jig |
