741-acre lake near Moose Pass. A deep, clear Kenai lake reached by trail from Ptarmigan Creek near Moose Pass, holding Dolly Varden and rainbow trout. The lake tops out around 246 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. The rest of this page walks each species through its year, using the map's own scoring.
The outline encloses 668 acres, worked by 7.9 miles of shoreline. An index of 2.2 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. About 1% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Tip to tip the water measures near 3.3 mi with a 0.6-mi widest point. It sits in Kenai Peninsula Borough. Upper Trail Lake sits 8 mi northwest — the closest neighbouring chart.
Spring puts arctic char in skinny water — 4 to 15 ft is the zone. As the season builds they drop to 20 to 60 ft, wintering in 10 to 40 ft. Spring arctic char concentrate at Shallow bay flat, a good-rated feeding flat around 6 ft. Warm-month bites cluster around early morning. 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 (6 ft) | Small casting spoon (silver/orange), Jerkbait (small) |
| Summer | 20 to 60 ft | dawn | Deep basin (209 ft) | Jigging spoon vertical, Tube jig (smelt) |
| Fall | 8 to 30 ft | midday & dusk | open water | Casting spoon (orange/gold), Beadhead streamer |
| Winter | 10 to 40 ft | midday & dawn | Deep basin (209 ft) | Jigging spoon (glow/silver), Tungsten jig + plastic |
Come spring, look for rainbow trout tight to the bank in 5 to 20 ft. Expect a summer slide to 8 to 30 ft, then a winter hold in 8 to 40 ft. Start at Shallow bay flat. It's a feeding flat holding about 6 ft of water and rates good come spring. Prime time lands in 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 | Shallow bay flat (6 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Shallow bay flat (6 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | open water | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (111 ft) | Jigging spoon, Tube jig (white) |
