42-acre lake near Three Lakes. The lake tops out around 36 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. Here's the year, species by species, as the scoring engine sees it.
The outline encloses 42 acres, worked by 1.2 miles of shoreline. At index 1.3 the outline is almost a bowl — read the depth changes, not the shoreline. About 23% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 0.5 mi long by 0.2 mi wide at the broadest reach. Snohomish County claims this one. Flowing Lake sits 1 mi east — the closest neighbouring chart.
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 7 to 36 ft. If you only fish one area, make it Deep basin: a deep basin around 36 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 | Shallow bay flat (7 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Shallow bay flat (7 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Deep basin (36 ft) | Casting spoon, Jerkbait over shoals |

Early season largemouth bass use the shallows, holding in 2 to 10 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 15 to 35 ft. Put Shallow bay flat first on the milk run — a weed flat near 7 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a texas-rigged 10" worm or a deep-diving crankbait and you're in the game.
