46-acre lake near Ilwaco. The lake tops out around 32 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. What follows comes from the same scoring engine that paints the spots above.
The drawn water covers 46 acres wrapped in 1.2 miles of bank. 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 68% of the water is 15 ft or less, the band where the food chain lives. Tip to tip the water measures near 0.5 mi with a 0.2-mi widest point. Pacific County claims this one. Island Lake sits 8 mi north — 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 6 to 32 ft. If you only fish one area, make it Break off the point: a drop-off around 22 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 | Main-lake point (9 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (22 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 9 to 32 ft | dawn & dusk | Main-lake point (9 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 10 to 32 ft. Put Shallow bay flat first on the milk run — a weed flat near 4 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.
