Rating depth structure for rainbow trout.
Recent public catches load as you reach this section.
33-acre lake in British Columbia. The lake tops out around 47 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. The season-by-season read for each species follows, from the map's own numbers.
The drawn water covers 32 acres wrapped in 1.1 miles of bank. At index 1.3 the outline is almost a bowl — read the depth changes, not the shoreline. Roughly 30% of the water is 15 ft or less as modeled, the band where the food chain lives. End to end it runs roughly 0.4 mi, about 0.2 mi across. It sits in Bulkley-Nechako Regional District. North Lake sits 1 mi northeast — the closest neighbouring chart.
Spring rainbow trout on Coppermine Lake hold shallow, usually 5 to 20 ft. By summer they slide out to 8 to 30 ft, and by winter most fish are in 8 to 40 ft. The chart's best answer is Break off the point — drop-off, 21 ft, prime for winter. Prime time lands in early morning and the evening. The summer box starts with a dodger + spoon (deep troll) or a flutter spoon.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (12 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (21 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (12 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (21 ft) | Jigging spoon, Tube jig (white) |
Early season kokanee use the shallows, holding in 10 to 30 ft. Expect a summer slide to 14 to 47 ft, then a winter hold in 12 to 47 ft. Put Deep basin first on the milk run — a deep basin near 40 ft that grades prime for summer. In summer the feeding windows fall in early morning. Tie on a dodger + pink/orange squid on downrigger or a kokanee bug + corn 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 30 ft | dawn | Break off the point (21 ft) | Small dodger + squid (pink), Wedding-ring spinner + corn |
| Summer | 14 to 47 ft chart-limited; documented 30 to 70 ft | dawn | Deep basin (40 ft) | Dodger + pink/orange squid on downrigger, Kokanee bug + corn |
| Fall | 5 to 40 ft | dawn | Deep basin (40 ft) | Dodger + squid (deeper red/purple), Small spoon |
| Winter | 12 to 47 ft chart-limited; documented 20 to 80 ft | dawn | Deep basin (40 ft) | Small glow jig + corn or maggot, Tiny spoon |
Start shallow in spring: lake whitefish sit in 15 to 45 ft that time of year. Summer pushes them deeper, 14 to 47 ft, and winter fish settle into 14 to 47 ft. The spot to know is Deep basin, a deep basin in about 40 ft of water that rates prime for lake whitefish in summer. Warm-month bites cluster around early morning. Throw a blade bait vertical or a small jigging spoon until the fish tell you otherwise.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Break off the point (21 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 14 to 47 ft chart-limited; documented 40 to 90 ft | dawn | Deep basin (40 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (21 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 14 to 47 ft chart-limited; documented 25 to 70 ft | midday & dawn | Deep basin (40 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
When the water first warms, burbot slide up into 14 to 47 ft. There's no big seasonal slide here — summer means 14 to 47 ft, winter 12 to 47 ft. If you only fish one area, make it Deep basin: a deep basin around 40 ft that scores prime in spring. In summer the feeding windows fall in after dark and midday. Keep a heavy jig + cut bait rigged through the warm months.

4 pieces of structure are mapped here — Deep basin, around 40 ft, is the deepest of them.

Coppermine Lake is about 47 ft (14 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, kokanee, lake whitefish, burbot on Coppermine 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.
Deep basin is the top-rated area: a deep basin in about 40 ft of water that rates prime for kokanee in summer. Scroll up to the map for the complete spot list by 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 Coppermine 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.
