58-acre lake near Sterling. A small roadside Kenai NWR lake stocked with rainbow trout, also holding coho salmon. The lake tops out around 14 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. Species by species, here's what the data says the year looks like.
Drawn out, this is 60 acres of water rimmed by 1.5 miles of bank. At index 1.4 the outline is almost a bowl — read the depth changes, not the shoreline. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. Tip to tip the water measures near 0.6 mi with a 0.3-mi widest point. The water lies in Kenai Peninsula Borough. The nearest mapped water is Egumen Lake, 2 mi to the southeast.
Spring puts rainbow trout in skinny water — 4 to 14 ft is the zone. Summer fish stay in 4 to 14 ft, and winter fish hold in 3 to 14 ft. Deep basin is the standout, a deep basin at roughly 7 ft, rated prime for winter rainbow trout. Plan around early morning and the evening in the warm months. A dodger + spoon (deep troll) or a flutter spoon covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 14 ft | dawn & dusk | Main-lake point (2 ft) | Inline spinner (silver), Small spoon |
| Summer | 4 to 14 ft | dawn & dusk | Deep basin (7 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 4 to 14 ft | dawn & dusk | Deep basin (7 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 3 to 14 ft | dawn | Deep basin (7 ft) | Jigging spoon, Tube jig (white) |
The spring pattern is a shallow one: coho salmon in 2 to 14 ft. The depth story barely changes: 4 to 14 ft through summer, 4 to 14 ft in winter. Top water on the chart: Deep basin, a deep basin in the 7 ft range, prime in summer. Time it for early morning and the evening. Summer baits: a dodger + fly or a medium spoon above the thermocline gets it done.
