225-acre lake near Sterling. A quiet Kenai NWR lake off Skilak Lake Road with coho salmon and Dolly Varden char. The lake tops out around 17 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. The rest of this page walks each species through its year, using the map's own scoring.
The drawn water covers 232 acres wrapped in 2.7 miles of bank. Nearly circular (index 1.3), so the story is the bottom, not the bank. The basin spans about 1 mi end to end and 0.7 mi across at its widest. It sits in Kenai Peninsula Borough. Hidden Lake sits 2 mi east — the closest neighbouring chart.
When the water first warms, coho salmon slide up into 2 to 17 ft. There's no big seasonal slide here — summer means 5 to 17 ft, winter 5 to 17 ft. Start at Deep basin. It's a deep basin holding about 13 ft of water and rates prime come summer. The feeding windows run early morning and the evening. Keep a dodger + fly or a medium spoon above the thermocline rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 17 ft | dawn & dusk | Main-lake point (2 ft) | Small orange dodger + peanut fly, Thin spoon (orange/silver) |
| Summer | 5 to 17 ft | dawn & dusk | Deep basin (13 ft) | Dodger + fly, Medium spoon above the thermocline |
| Fall | 3 to 17 ft | dawn & dusk | Break off the point (8 ft) | Casting spoon, Spinner (chartreuse) |
| Winter | 5 to 17 ft | midday | Deep basin (13 ft) | Small spoon, slow troll |
The spring pattern is a shallow one: arctic char in 4 to 15 ft. As the season builds they drop to 5 to 17 ft, wintering in 4 to 17 ft. Top water on the chart: Deep basin, a deep basin in the 13 ft range, prime in summer. Time it for early morning. Summer baits: a jigging spoon vertical or a tube jig (smelt) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | midday & dawn | Break off the point (8 ft) | Small casting spoon (silver/orange), Jerkbait (small) |
| Summer | 5 to 17 ft | dawn | Deep basin (13 ft) | Jigging spoon vertical, Tube jig (smelt) |
| Fall | 5 to 17 ft | midday & dusk | Break off the point (8 ft) | Casting spoon (orange/gold), Beadhead streamer |
| Winter | 4 to 17 ft | midday & dawn | Deep basin (13 ft) | Jigging spoon (glow/silver), Tungsten jig + plastic |
