Rating depth structure for lake trout.
Recent public catches load as you reach this section.
498-acre lake in British Columbia. The lake tops out around 144 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. What the data behind the map says about each species, season by season:
The drawn water covers 497 acres wrapped in 5.5 miles of bank. A middling shoreline index (1.8) gives it some bays to work without being a maze. Roughly 13% of the water is 15 ft or less as modeled, the band where the food chain lives. The basin spans about 2.4 mi end to end and 0.5 mi across at its widest. It sits in Stikine Region. If the bite dies, Dixie Lake is 12 mi to the northeast.
These fish are listed in an exact-water agency record as forage or ecological context. They are not target-species profiles and do not affect DepthScout's Prime, Good, or Fair spot ratings.
Official exact-water fish record. The listing documents source-recorded presence, not present abundance or guaranteed catchability.
Early season lake trout use the shallows, holding in 10 to 40 ft. Expect a summer slide to 50 to 120 ft, then a winter hold in 20 to 80 ft. Put Deep basin first on the milk run — a deep basin near 122 ft that grades prime for summer. In summer the feeding windows fall in early morning. Tie on a white tube jig (deep) or a magnum spoon on downrigger and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (36 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 50 to 120 ft | dawn | Deep basin (122 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (36 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Break off the point (65 ft) | White tube jig, Airplane jig |
Simpson Lake carries 6 mapped structure features, topping out (or rather bottoming out) at Deep basin, about 122 ft down.
