139-acre lake near Yakima County. The lake tops out around 6 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 is how the season plays out for each species, straight from the data behind the map.
The outline encloses 139 acres, worked by 2.2 miles of shoreline. Its 1.4 shoreline index means few bank features; the contours below do the pattern work. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. Tip to tip the water measures near 1 mi with a 0.3-mi widest point. It sits in Yakima County. If the bite dies, Columbia River - Reach 5 of 5 is 31 mi to the south.
When the water first warms, largemouth bass slide up into 1 to 6 ft. There's no big seasonal slide here — summer means 2 to 6 ft, winter 2 to 6 ft. Start at Shallow bay flat. It's a weed flat holding about 1 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a texas-rigged 10" worm or a deep-diving crankbait rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | dawn & dusk | Shallow bay flat (1 ft) | Spinnerbait, Chatterbait |

| Fall | 2 to 6 ft | midday & dawn | Main-lake point (1 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 2 to 6 ft | midday | Break off the point (2 ft) | Blade bait, Jigging spoon |
Come spring, look for smallmouth bass tight to the bank in 2 to 6 ft. Through summer count on 2 to 6 ft; the winter hold is 2 to 6 ft. If you only fish one area, make it Break off the point: a drop-off around 2 ft that scores prime in winter. Best bite is early morning and the evening. A drop shot (goby/minnow) or a ned rig is the honest summer answer here.

Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.
