Rating depth structure for coho salmon.
Recent public catches load as you reach this section.
730-acre lake in British Columbia. The lake tops out around 177 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. Here is how the season plays out for each species, straight from the data behind the map.
Drawn out, this is 728 acres of water rimmed by 13.1 miles of bank. An index of 3.5 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. 4% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. End to end it runs roughly 3.1 mi, about 1.9 mi across. The water lies in Skeena-Queen Charlotte Regional District. Closest neighbour on DepthScout: Devon Lake, 9 mi northwest of here.

Spring puts coho salmon in skinny water — 3 to 25 ft is the zone. As the season builds they drop to 30 to 70 ft, wintering in 20 to 60 ft. Fall coho salmon concentrate at Main-lake point, a prime-rated point around 44 ft. Warm-month bites cluster around early morning and the evening. A dodger + fly or a medium spoon above the thermocline covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | open water | Small orange dodger + peanut fly, Thin spoon (orange/silver) |
| Summer | 30 to 70 ft | dawn & dusk | Break off the point (80 ft) | Dodger + fly, Medium spoon above the thermocline |
| Fall | 8 to 40 ft | dawn & dusk | Main-lake point (44 ft) | Casting spoon, Spinner (chartreuse) |
| Winter | 20 to 60 ft | midday | open water | Small spoon, slow troll |
Spring cutthroat trout on Tuwartz Lake hold shallow, usually 3 to 15 ft. They move out to 10 to 35 ft in summer and finish the year down in 10 to 40 ft. Put Main-lake point first on the milk run — a point near 44 ft that grades good for winter. The feeding windows run early morning and the evening. The summer box starts with a trolled spoon (small) or an inline spinner.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | open water | Inline spinner (silver/gold), Small spoon |
| Summer | 10 to 35 ft | dawn & dusk | Main-lake point (44 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | open water | Casting spoon, Inline spinner |
| Winter | 10 to 40 ft | dawn | Main-lake point (44 ft) | Small jigging spoon, Marabou jig |
The spring pattern is a shallow one: kokanee in 10 to 30 ft. Midsummer fish sit out in 30 to 70 ft before dropping to 20 to 80 ft for winter. The spot to know is Break off the point, a drop-off in about 80 ft of water that rates good for kokanee in winter. Plan around early morning in the warm months. Summer baits: a dodger + pink/orange squid on downrigger or a kokanee bug + corn gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 30 ft | dawn | open water | Small dodger + squid (pink), Wedding-ring spinner + corn |
| Summer | 30 to 70 ft | dawn | Break off the point (80 ft) | Dodger + pink/orange squid on downrigger, Kokanee bug + corn |
| Fall | 5 to 40 ft | dawn | open water | Dodger + squid (deeper red/purple), Small spoon |
| Winter | 20 to 80 ft | dawn | Break off the point (80 ft) | Small glow jig + corn or maggot, Tiny spoon |
