Rating depth structure for rainbow trout.

130-acre lake in British Columbia. The lake tops out around 13 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. What follows comes from the same scoring engine that paints the spots above.
The outline encloses 129 acres, worked by 2.2 miles of shoreline. Nearly circular (index 1.4), so the story is the bottom, not the bank. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. The basin spans about 0.7 mi end to end and 0.5 mi across at its widest. It sits in Bulkley-Nechako Regional District. If the bite dies, Skins Lake is 5 mi to the northwest.
Early season rainbow trout use the shallows, holding in 3 to 13 ft. Even in summer they hold at 3 to 13 ft; winter keeps them in 3 to 13 ft. Put Break off the point first on the milk run — a drop-off near 6 ft that grades prime for winter. In summer the feeding windows fall in early morning and the evening. Tie on a dodger + spoon (deep troll) or a flutter 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 | 3 to 13 ft chart-limited; documented 5 to 20 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 3 to 13 ft chart-limited; documented 8 to 30 ft | dawn & dusk | Break off the point (6 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 4 to 13 ft chart-limited; documented 10 to 35 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 3 to 13 ft chart-limited; documented 8 to 40 ft | dawn | Break off the point (6 ft) | Jigging spoon, Tube jig (white) |
Island Lake carries 6 mapped structure features, topping out (or rather bottoming out) at Deep basin, about 11 ft down.
Season dates, license requirements, and size and bag limits for British Columbia waters are set by the BC freshwater fishing synopsis — and special regulations can apply to Island Lake specifically, so confirm the current rules before you fish.

Island Lake is about 13 ft (4 m) deep at its deepest point. The contours here are modeled from the water's real shape and maximum depth, so treat them as a rough guide.
Anglers target rainbow trout on Island Lake. This isn't a survey of the water — none is published for it — but an informed estimate from the species common to the region, narrowed by this water's depth, size and each species' range.
Break off the point is the top-rated area: a drop-off in about 6 ft of water that rates prime for rainbow trout in winter. Open the map above to see every rated spot for each species and season.
For rainbow trout, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
Fishing on Island Lake is regulated by the BC freshwater fishing synopsis. Check the official British Columbia regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
