1,860-acre lake near Little Hoquiam. The lake tops out around 90 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Below is the species-by-species picture, pulled from the same data the map uses.
Drawn out, this is 1,860 acres of water rimmed by 7.8 miles of bank. Nearly circular (index 1.3), so the story is the bottom, not the bank. The shallow band under 15 ft claims about 27% of the surface — that's where the groceries are. Tip to tip the water measures near 3.5 mi with a 1.3-mi widest point. You'll find it in Mason County. The nearest mapped water is Benson Lake, 2 mi to the east.
When the water first warms, cutthroat trout slide up into 3 to 15 ft. By summer they slide out to 10 to 35 ft, and by winter most fish are in 10 to 40 ft. If you only fish one area, make it Creek inflow: an inflow / creek mouth around 1 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Keep a trolled spoon (small) or an inline spinner rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | Creek inflow (1 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 10 to 35 ft | dawn & dusk | Main-lake point (1 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | Main-lake point (1 ft) | Casting spoon, Inline spinner |
| Winter | 10 to 40 ft | dawn | Main-lake point (1 ft) | Small jigging spoon, Marabou jig |
Spring puts kokanee in skinny water — 10 to 30 ft is the zone. As the season builds they drop to 30 to 70 ft, wintering in 20 to 80 ft. Winter kokanee concentrate at Deep basin, a prime-rated deep basin around 90 ft. Warm-month bites cluster around early morning. A dodger + pink/orange squid on downrigger or a kokanee bug + corn covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 30 ft | dawn | open water | Small dodger + squid (pink), Wedding-ring spinner + corn |
| Summer | 30 to 70 ft | dawn | Break off the point (67 ft) | Dodger + pink/orange squid on downrigger, Kokanee bug + corn |
| Fall | 5 to 40 ft | dawn | Creek inflow (1 ft) | Dodger + squid (deeper red/purple), Small spoon |
| Winter | 20 to 80 ft | dawn | Deep basin (90 ft) | Small glow jig + corn or maggot, Tiny spoon |
In spring, rainbow trout run shallow here, mostly 5 to 20 ft. Summer pushes them deeper, 8 to 30 ft, and winter fish settle into 8 to 40 ft. Creek inflow is the standout, an inflow / creek mouth at roughly 1 ft, rated good for spring rainbow trout. Time it for early morning and the evening. You won't need more than a dodger + spoon (deep troll) or a flutter spoon most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Creek inflow (1 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Creek inflow (1 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (1 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Creek inflow (1 ft) | Jigging spoon, Tube jig (white) |
Spring puts brown bullhead in skinny water — 2 to 8 ft is the zone. Warm water sends them out to 3 to 12 ft; cold water stacks them in 10 to 25 ft. Shallow bay flat is the standout, a weed flat at roughly 1 ft, rated prime for spring brown bullhead. Plan around after dark and the evening in the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (1 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (1 ft) | |
| Fall | 5 to 15 ft | dusk | open water | |
| Winter | 10 to 25 ft | midday | open water |
Start shallow in spring: largemouth bass sit in 2 to 10 ft that time of year. Warm water sends them out to 8 to 20 ft; cold water stacks them in 15 to 35 ft. Top water on the chart: Shallow bay flat, a weed flat in the 1 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a texas-rigged 10" worm or a deep-diving crankbait until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (1 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Shallow feeding flat (18 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (1 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | open water | Blade bait, Jigging spoon |
When the water first warms, yellow perch slide up into 3 to 12 ft. Summer is a 10 to 30 ft game here, winter a 15 to 35 ft one. 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. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Shallow feeding flat (24 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | open water | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Shallow feeding flat (24 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Structure-wise the chart holds 13 features, led in depth by Deep basin at roughly 90 ft.
