Rating depth structure for rainbow trout.

3,942-acre lake in Stikine Region, British Columbia. The lake tops out around 466 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. Every species below gets its seasonal read from the same numbers driving the chart.
Traced from the shoreline, Tatsamenie Lake runs 4,056 acres with 28.2 miles of edge, broken up by 5 islands. A development index of 3.2 means a maze of bays and points: far more casting targets than a round bowl of the same size. The shallow band under 15 ft claims about 0% of the surface on the model — that's where the groceries are. Tip to tip the water measures near 8.7 mi with a 4.2-mi widest point. The water lies in Stikine Region. Closest neighbour on DepthScout: Tatsatua Lake, 7 mi north of here.
In spring, lake trout run shallow here, mostly 10 to 40 ft. Summer pushes them deeper, 50 to 120 ft, and winter fish settle into 20 to 80 ft. Offshore hump is the standout, an offshore hump at roughly 61 ft, rated prime for summer lake trout. Time it for early morning. You won't need more than a white tube jig (deep) or a magnum spoon on downrigger most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Offshore hump (50 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 50 to 120 ft | dawn | Offshore hump (61 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Offshore hump (50 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Offshore hump (61 ft) | White tube jig, Airplane jig |
In spring, rainbow trout run shallow here, mostly 5 to 20 ft. Midsummer fish sit out in 8 to 30 ft before dropping to 8 to 40 ft for winter. Spring rainbow trout concentrate at Shallow bay flat, a good-rated feeding flat around 6 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a dodger + spoon (deep troll) or a flutter spoon most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Shallow bay flat (6 ft) | Inline spinner (silver), Small spoon |
