3,065-acre Quartermaster Harbor fishing map with native-MLLW NOAA survey contours (76.74% measured, 95.61% assessed), 49 measured spots, nine source-bounded fish profiles, exact herring, surf-smelt and sand-lance calendars, two public launches, Marine Area 11 rules and health guidance. The water tops out around 153 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. The rest of this page walks each species through its year, using the map's own scoring.
The outline encloses 3,058 acres, worked by 16.7 miles of shoreline. A development index of 2.2 means a maze of bays and points: far more casting targets than a round bowl of the same size. 31% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Call it 5.3 mi long by 2.1 mi wide at the broadest reach. Poverty Bay sits 6 mi east — the closest neighbouring chart.
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 43 to 153 ft. Put NOAA H11551/H05932 measured channel break first on the milk run — a channel edge near 70 ft that grades prime for summer. 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 | NOAA H11551/H05932 measured channel break (70 ft) | Herring-pattern spoon, Three-to-four-inch baitfish swimbait |
| Summer | 20 to 150 ft | dawn & dusk | NOAA H11551/H05932 measured channel break (70 ft) | Herring or sand-lance spoon, Baitfish hoochie behind a flasher |
| Fall | 10 to 100 ft | dawn & dusk | NOAA H11551/H05932 measured channel break (70 ft) | Compact spoon, Baitfish spinner where legal |
| Winter | 43 to 153 ft | midday | NOAA H11551/H05932 measured inlet-channel depth (152 ft) | Slow-trolled spoon, Deep baitfish plug |
Spring pacific coho salmon on Quartermaster 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 NOAA H11551/H05932 measured channel break first on the milk run — a channel edge near 70 ft that grades prime for summer. 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 | NOAA H11551/H05932 measured channel break (70 ft) | Small silver spoon, Slim baitfish fly |
| Summer | 10 to 100 ft | dawn & dusk | NOAA H11551/H05932 measured channel break (70 ft) | Small hoochie behind a flasher, Slim spoon |
| Fall | 5 to 60 ft | dawn & dusk | NOAA H11551/H05932 measured channel break (70 ft) | Small spinner where legal, Compact spoon |
| Winter | 30 to 100 ft | midday | NOAA H11551/H05932 measured channel break (70 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, 16 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 | NOAA H11551/H05932 measured channel break (70 ft) | Chrome spoon, Compact baitfish jig |
| Summer | 4 to 70 ft | dawn & dusk | NOAA charted underwater rock (16 ft) | Chartreuse or pink hoochie, Bright spoon |
| Fall | 3 to 60 ft | dawn & dusk | NOAA charted underwater rock (16 ft) | Bright spinner, Pink or chartreuse jig |
| Winter | 25 to 100 ft | midday | NOAA H11551/H05932 measured channel break (70 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 16 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 (47 ft) | Small chrome spoon, Compact herring-pattern jig |
| Summer | 3 to 70 ft | dawn & dusk | NOAA charted underwater rock (16 ft) | Pink or orange casting spoon, Small hoochie |
| Fall | 2 to 60 ft | dawn & dusk | NOAA charted underwater rock (16 ft) | Small bright spoon, Pink jig |
| Winter | 20 to 90 ft | midday | NOAA H11551/H05932 measured channel break (70 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 16 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 (5 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 10 to 35 ft | dawn & dusk | NOAA charted underwater rock (16 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | NOAA charted underwater rock (16 ft) | Casting spoon, Inline spinner |
| Winter | 10 to 40 ft | dawn | NOAA charted underwater rock (16 ft) | Small jigging spoon, Marabou jig |
When the water first warms, english sole slide up into 30 to 120 ft. There's no big seasonal slide here — summer means 10 to 90 ft, winter 34 to 153 ft. Start at NOAA H11551/H05932 measured channel break. It's a channel edge holding about 70 ft of water and rates prime come summer. The feeding windows run early morning. Keep a small scented jig or a light grub on bottom rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 30 to 120 ft | midday | NOAA H11551/H05932 measured channel break (70 ft) | Small scented bottom jig, Light bucktail |
| Summer | 10 to 90 ft | dawn | NOAA H11551/H05932 measured channel break (70 ft) | Small scented jig, Light grub on bottom |
| Fall | 25 to 140 ft | midday | NOAA H11551/H05932 measured channel break (70 ft) | Slow bucktail, Small bottom jig |
| Winter | 34 to 153 ft | midday | NOAA H11551/H05932 measured inlet-channel depth (152 ft) | Slow scented bottom jig |
