107-acre lake in British Columbia. The lake tops out around 67 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. Species by species, here's what the data says the year looks like.
On the chart, Gunflint Lake draws 107 acres inside 1.9 miles of shoreline. A shoreline index of 1.3 says round and simple: fish relate to depth changes here, not shoreline features. Littoral water — the productive band under ~15 ft — makes up 16% of this chart, as modeled. Call it 0.7 mi long by 0.4 mi wide at the broadest reach. The water lies in Strathcona Regional District. For a second option, Hague Lake lies 1 mi southwest.
Spring puts rainbow trout in skinny water — 5 to 20 ft is the zone. Warm water sends them out to 8 to 30 ft; cold water stacks them in 8 to 40 ft. Break off the point is the standout, a drop-off at roughly 30 ft, rated prime for winter rainbow trout. Plan around early morning and the evening in the warm months. A dodger + spoon (deep troll) or a flutter spoon covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (17 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (30 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (17 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (30 ft) | Jigging spoon, Tube jig (white) |
In spring, kokanee run shallow here, mostly 10 to 30 ft. Midsummer fish sit out in 20 to 67 ft before dropping to 17 to 67 ft for winter. Summer kokanee concentrate at Deep basin, a prime-rated deep basin around 57 ft. Fish it in early morning and you'll meet the bite. You won't need more than a dodger + pink/orange squid on downrigger or a kokanee bug + corn most summer days.
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 (30 ft) | Small dodger + squid (pink), Wedding-ring spinner + corn |
| Summer | 20 to 67 ft chart-limited; documented 30 to 70 ft | dawn | Deep basin (57 ft) | Dodger + pink/orange squid on downrigger, Kokanee bug + corn |
| Fall | 5 to 40 ft | dawn | Break off the point (30 ft) | Dodger + squid (deeper red/purple), Small spoon |
| Winter | 17 to 67 ft chart-limited; documented 20 to 80 ft | dawn | Deep basin (57 ft) | Small glow jig + corn or maggot, Tiny spoon |
Early season lake whitefish use the shallows, holding in 15 to 45 ft. Expect a summer slide to 20 to 67 ft, then a winter hold in 20 to 67 ft. Put Deep basin first on the milk run — a deep basin near 57 ft that grades prime for summer. In summer the feeding windows fall in early morning. Tie on a blade bait vertical or a small jigging spoon and you're in the game.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Break off the point (30 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 20 to 67 ft chart-limited; documented 40 to 90 ft | dawn | Deep basin (57 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (30 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 20 to 67 ft chart-limited; documented 25 to 70 ft | midday & dawn | Deep basin (57 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Spring puts burbot in skinny water — 20 to 67 ft is the zone. Summer fish stay in 20 to 67 ft, and winter fish hold in 15 to 60 ft. Spring burbot concentrate at Deep basin, a prime-rated deep basin around 57 ft. Warm-month bites cluster around after dark and midday. A heavy jig + cut bait covers the summer program.

Gunflint Lake is about 67 ft (20 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 Gunflint 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 57 ft of water that rates prime for kokanee in summer. The interactive chart above rates every 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.
