33,386-acre bay near Westport. The water tops out around 116 ft. The depth chart is built from real agency bathymetric surveys, so measured depths remain distinct from source interpolation. The channels, holes and drop-offs come from the source data, not a distance-from-shore model. Species by species, here's what the data says the year looks like.
The drawn water covers 32,699 acres wrapped in 55.1 miles of bank — 7 islands included. An index of 2.2 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. The shallow band under 15 ft claims about 74% of the surface — that's where the groceries are. End to end it runs roughly 15.5 mi, about 6.2 mi across. Its nearest charted neighbour, Duck Lake, is 7 mi to the northwest.
Spring chinook salmon on Grays Harbor hold shallow, usually 5 to 40 ft. By summer they slide out to 35 to 116 ft, and by winter most fish are in 30 to 90 ft. The chart's best answer is Indian Creek inflow — inflow / creek mouth, 6 ft, prime for spring. Prime time lands in early morning and the evening. The summer box starts with a flasher + fly (green/white) or a magnum spoon on downrigger.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 40 ft | dawn & dusk | Indian Creek inflow (6 ft) | Trolled spoon (orange/gold), Stickbait off planer boards |
| Summer | 35 to 116 ft | dawn & dusk | Deep basin (100 ft) | Flasher + fly (green/white), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dawn & dusk | Indian Creek inflow (6 ft) | J-plug (glow), Flasher + fly |
| Winter | 30 to 90 ft | midday | Deep basin (100 ft) | Small spoon on a slow troll, Stickbait deep |
Early season coho salmon use the shallows, holding in 3 to 25 ft. Summer is a 30 to 70 ft game here, winter a 20 to 60 ft one. The chart's best answer is Indian Creek inflow — inflow / creek mouth, 6 ft, prime for spring. Best bite is early morning and the evening. Tie on a dodger + fly or a medium spoon above the thermocline and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Indian Creek inflow (6 ft) | Small orange dodger + peanut fly, Thin spoon (orange/silver) |
| Summer | 30 to 70 ft | dawn & dusk | Sharp break (24 ft) | Dodger + fly, Medium spoon above the thermocline |
| Fall | 8 to 40 ft | dawn & dusk | Indian Creek inflow (6 ft) | Casting spoon, Spinner (chartreuse) |
| Winter | 20 to 60 ft | midday | Sharp break (24 ft) | Small spoon, slow troll |
Start shallow in spring: cutthroat trout sit in 3 to 15 ft that time of year. Warm water sends them out to 10 to 35 ft; cold water stacks them in 10 to 40 ft. Top water on the chart: Indian Creek inflow, an inflow / creek mouth in the 6 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a trolled spoon (small) or an inline spinner until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | Indian Creek inflow (6 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 10 to 35 ft | dawn & dusk | Break off the point (16 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Inline spinner |
| Winter | 10 to 40 ft | dawn | Break off the point (16 ft) | Small jigging spoon, Marabou jig |
Structure-wise the chart holds 24 features, led in depth by Deep basin at roughly 100 ft.
