832-acre lake near Sterling. A hub of the Swan Lake canoe route in the Kenai NWR, holding rainbow trout, Dolly Varden and coho salmon. The lake tops out around 44 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. Every species below gets its seasonal read from the same numbers driving the chart.
Early season coho salmon use the shallows, holding in 3 to 25 ft. Expect a summer slide to 13 to 44 ft, then a winter hold in 13 to 44 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 and the evening. Tie on a dodger + fly or a medium spoon above the thermocline and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Break off the point (25 ft) | Small orange dodger + peanut fly, Thin spoon (orange/silver) |
| Summer | 13 to 44 ft | dawn & dusk | Deep basin (40 ft) | Dodger + fly, Medium spoon above the thermocline |
| Fall | 8 to 40 ft | dawn & dusk | Break off the point (25 ft) | Casting spoon, Spinner (chartreuse) |
| Winter | 13 to 44 ft | midday | Deep basin (40 ft) | Small spoon, slow troll |
Come spring, look for rainbow trout tight to the bank in 5 to 20 ft. They move out to 8 to 30 ft in summer and finish the year down in 8 to 40 ft. If you only fish one area, make it Break off the point: a drop-off around 25 ft that scores prime in winter. Best bite is early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (1 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (25 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Break off the point (25 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (25 ft) | Jigging spoon, Tube jig (white) |
Spring puts arctic char in skinny water — 4 to 15 ft is the zone. Warm water sends them out to 13 to 44 ft; cold water stacks them in 10 to 40 ft. Deep basin is the standout, a deep basin at roughly 40 ft, rated prime for summer arctic char. Plan around early morning in the warm months. A jigging spoon vertical or a tube jig (smelt) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | midday & dawn | Shallow bay flat (1 ft) | Small casting spoon (silver/orange), Jerkbait (small) |
| Summer | 13 to 44 ft | dawn | Deep basin (40 ft) | Jigging spoon vertical, Tube jig (smelt) |
| Fall | 8 to 30 ft | midday & dusk | Break off the point (25 ft) | Casting spoon (orange/gold), Beadhead streamer |
| Winter | 10 to 40 ft | midday & dawn | Deep basin (40 ft) | Jigging spoon (glow/silver), Tungsten jig + plastic |
