253-acre Blakely Harbor fishing map with native-MLLW NOAA survey contours (93.27% measured, 97.66% assessed), 14 source-traceable measured fishing spots, seven sourced fish profiles, exact mapped forage habitat, public kayak access, Marine Area 10 rules and health guidance. The water tops out around 167 ft. The depth chart is built from real agency bathymetry referenced to MLLW; directly measured coverage remains distinguished 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 252 acres wrapped in 3.6 miles of bank. With a 1.6 development index there's bank structure worth casting at, in moderation. About 25% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 1.4 mi long by 0.5 mi wide at the broadest reach. If the bite dies, Eagle Harbor is 2 mi to the north.
Early season pacific chinook salmon use the shallows, holding in 30 to 120 ft. Expect a summer slide to 20 to 150 ft, then a winter hold in 46 to 167 ft. Put NOAA H12025 and H05711 measured inlet-channel depth first on the milk run — a channel edge near 165 ft that grades prime for winter. In summer the feeding windows fall in early morning and the evening. Tie on a herring or sand-lance spoon or a baitfish hoochie behind a flasher and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 30 to 120 ft | dawn | Surveyed channel edge (87 ft) | Herring-pattern spoon, Three-to-four-inch baitfish swimbait |
| Summer | 20 to 150 ft | dawn & dusk | NOAA H12025 and H05711 measured inlet-channel depth (165 ft) | Herring or sand-lance spoon, Baitfish hoochie behind a flasher |
| Fall | 10 to 100 ft | dawn & dusk | Surveyed channel edge (87 ft) | Compact spoon, Baitfish spinner where legal |
| Winter | 46 to 167 ft | midday | NOAA H12025 and H05711 measured inlet-channel depth (165 ft) | Slow-trolled spoon, Deep baitfish plug |
Spring pacific coho salmon on Blakely Harbor hold shallow, usually 10 to 70 ft. They move out to 10 to 100 ft in summer and finish the year down in 30 to 100 ft. Put Surveyed channel edge first on the milk run — a drop-off near 23 ft that grades good for spring. The feeding windows run early morning and the evening. The summer box starts with a small hoochie behind a flasher or a slim spoon.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 70 ft | dawn & dusk | Surveyed channel edge (23 ft) | Small silver spoon, Slim baitfish fly |
| Summer | 10 to 100 ft | dawn & dusk | Surveyed channel edge (87 ft) | Small hoochie behind a flasher, Slim spoon |
| Fall | 5 to 60 ft | dawn & dusk | Surveyed channel edge (23 ft) | Small spinner where legal, Compact spoon |
| Winter | 30 to 100 ft | midday | Surveyed channel edge (87 ft) | Slow small spoon, Compact trolling fly |
Early season chum salmon use the shallows, holding in 10 to 70 ft. Even in summer they hold at 4 to 70 ft; winter keeps them in 25 to 100 ft. The chart's best answer is NOAA charted underwater rock — rock pile, 12 ft, prime for summer. Best bite is early morning and the evening. Tie on a chartreuse or pink hoochie or a bright spoon and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 70 ft | dawn & dusk | Surveyed channel edge (23 ft) | Chrome spoon, Compact baitfish jig |
| Summer | 4 to 70 ft | dawn & dusk | NOAA charted underwater rock (12 ft) | Chartreuse or pink hoochie, Bright spoon |
| Fall | 3 to 60 ft | dawn & dusk | NOAA charted underwater rock (12 ft) | Bright spinner, Pink or chartreuse jig |
| Winter | 25 to 100 ft | midday | Surveyed channel edge (87 ft) | Compact vertical jig |
Spring puts pink salmon in skinny water — 8 to 60 ft is the zone. As the season builds they drop to 3 to 70 ft, wintering in 20 to 90 ft. Summer pink salmon concentrate at NOAA charted underwater rock, a prime-rated rock pile around 12 ft. Warm-month bites cluster around early morning and the evening. A pink or orange casting spoon or a small hoochie covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 60 ft | dawn & dusk | Surveyed channel edge (23 ft) | Small chrome spoon, Compact herring-pattern jig |
| Summer | 3 to 70 ft | dawn & dusk | NOAA charted underwater rock (12 ft) | Pink or orange casting spoon, Small hoochie |
| Fall | 2 to 60 ft | dawn & dusk | NOAA charted underwater rock (12 ft) | Small bright spoon, Pink jig |
| Winter | 20 to 90 ft | midday | Surveyed channel edge (87 ft) | Small vertical jig |
Spring puts cutthroat trout in skinny water — 3 to 15 ft is the zone. As the season builds they drop to 10 to 35 ft, wintering in 10 to 40 ft. Fall cutthroat trout concentrate at NOAA charted underwater rock, a prime-rated rock pile around 12 ft. Warm-month bites cluster around early morning and the evening. A trolled spoon (small) or an inline spinner covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | NOAA charted underwater rock (12 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 10 to 35 ft | dawn & dusk | NOAA charted underwater rock (12 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | NOAA charted underwater rock (12 ft) | Casting spoon, Inline spinner |
| Winter | 10 to 40 ft | dawn | NOAA charted underwater rock (12 ft) | Small jigging spoon, Marabou jig |
When the water first warms, lingcod slide up into 25 to 140 ft. By summer they slide out to 19 to 167 ft, and by winter most fish are in 42 to 167 ft. If you only fish one area, make it NOAA charted underwater rock: a rock pile around 19 ft that scores prime in summer. In summer the feeding windows fall in midday and early morning. Keep a heavy swimbait or a metal jig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 25 to 140 ft | dawn | NOAA charted underwater rock (19 ft) | Heavy swimbait, Metal jig |
| Summer | 19 to 167 ft | midday & dawn | NOAA charted underwater rock (19 ft) | Heavy swimbait, Metal jig |
| Fall | 25 to 167 ft | midday | NOAA charted underwater rock (19 ft) | Heavy metal jig, Large swimbait |
| Winter | 42 to 167 ft | midday | Dangerous NOAA charted wreck (41 ft) | Heavy slow-pitch jig |
