10-acre stocked lake in the Anchorage area. ADF&G sonar-surveyed water with stocked rainbow trout. The lake tops out around 31 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. Below is the species-by-species picture, pulled from the same data the map uses.
Lake Otis maps at 10 acres behind 0.5 miles of shoreline. The basin is a simple one (shoreline index 1.2) — close to a bowl, so the structure on the chart matters more than the bank. Roughly 45% of the water is 15 ft or less, the band where the food chain lives. It sits in Anchorage Borough. If the bite dies, Waldron Lake is 1 mi to the south.
Early season rainbow trout use the shallows, holding in 5 to 20 ft. Expect a summer slide to 8 to 30 ft, then a winter hold in 6 to 31 ft. Put Shallow feeding flat first on the milk run — a feeding flat near 19 ft that grades good for spring. In summer the feeding windows fall in early morning and the evening. Tie on a dodger + spoon (deep troll) or a flutter spoon and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Shallow feeding flat (19 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Shallow feeding flat (19 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 9 to 31 ft | dawn & dusk | open water | Casting spoon, Jerkbait over shoals |
| Winter | 6 to 31 ft | dawn | open water | Jigging spoon, Tube jig (white) |
