Puget Sound is one of the most complex and rewarding salmon fisheries in the Pacific Northwest. Unlike the open ocean or individual river systems, Puget Sound contains multiple species, dozens of distinct runs, overlapping seasons managed area by area, and a variety of productive techniques from downrigger trolling to jigging and mooching. For anglers willing to invest the time to understand the system, it offers year-round opportunity from a boat within easy reach of the most densely populated part of Washington State.

This guide provides a comprehensive overview of Puget Sound salmon fishing — the species and runs, the marine area structure, seasonal patterns, and the techniques that consistently produce fish.

Species in Puget Sound

Chinook Salmon (King)

Chinook (Oncorhynchus tshawytscha) are the largest Pacific salmon and the most coveted species in Puget Sound. Adult chinook typically run 15-35 pounds in Puget Sound, with fish over 40 pounds caught every season.

Puget Sound chinook fishing has two primary phases:

Blackmouth: Immature chinook (2-3 year old fish that haven't yet migrated to the ocean) overwinter in Puget Sound and provide the primary winter and early spring salmon fishery. Blackmouth typically run 4-12 pounds and are identified by their black gums and lack of spawning coloration. The blackmouth fishery runs from October through April in most areas, offering year-round opportunity when summer seasons are closed.

Adult chinook: Mature chinook return to Puget Sound tributaries from late spring through fall. The peak adult chinook fishery varies by marine area — some areas see strong runs in May-June (early tule chinook), while others peak in August and September as fish stage for river entry.

Coho Salmon (Silver)

Coho (Oncorhynchus kisutch) are the most widely pursued Puget Sound salmon due to their aggressive behavior, consistent availability, and excellent table quality. Adult coho typically run 6-12 pounds with fish to 15+ pounds taken regularly.

Puget Sound coho fishing peaks from August through October as adult fish return from the ocean and stage in the Sound before entering rivers. Coho are generally shallower than chinook — most productive depths are 15-50 feet — and more likely to show surface activity around bait schools.

Pink Salmon (Humpy)

Pink salmon (Oncorhynchus gorbuscha) return to Puget Sound on odd-numbered years only (2025, 2027, etc.) in massive numbers — often millions of fish entering the Sound in late July through September. Pink salmon run small (3-6 lbs average) but provide exceptional high-action fishing with light tackle. During a strong pink year, limits of pinks are routinely achieved in under an hour.

Chum Salmon (Dog)

Chum salmon (Oncorhynchus keta) return to Puget Sound rivers from October through December. They're the second-largest Pacific salmon species after chinook and are powerful fighters. Marine chum fishing opportunities are more limited than other species — most chum harvest occurs near river mouths as fish are staging to enter freshwater. Chum salmon have excellent roe and are underrated table fare when bled and iced immediately.

Understanding Puget Sound Marine Areas

WDFW manages Puget Sound salmon fishing through numbered marine areas, each with its own season dates, species regulations, and quota tracking. The main areas and their general locations:

  • Marine Area 7: San Juan Islands and north Puget Sound
  • Marine Area 8-1 and 8-2: Deception Pass to Edmonds area
  • Marine Area 9: Admiralty Inlet and north central Sound
  • Marine Area 10: Central Puget Sound (Seattle to Tacoma area) — the most heavily fished area
  • Marine Area 11: Tacoma Narrows and south Sound
  • Marine Area 12: Hood Canal
  • Marine Area 13: South Sound (Olympia area)

Each area opens and closes independently based on run strength, harvest quotas, and stock-specific management objectives. A marine area that's open one weekend may close the following weekend if quota is reached. Monitoring WDFW's weekly updates and fishing report hotlines is essential for current-season planning.

Marine Area 10: The Heart of Puget Sound Salmon Fishing

Marine Area 10 — roughly the central Sound from Edmonds south to Tacoma, including the main basin of the Sound — is the most productive and most accessible area for the majority of Puget Sound anglers. Seattle-area boaters have short runs to productive water, and the area typically holds strong chinook and coho returns.

Blackmouth: MA10 blackmouth fishing typically runs from October through early spring. Fish concentrate near underwater structure and bait schools in the deeper portions of the central basin — depths of 80-150 feet are most productive. The area around Point Jefferson, Jefferson Head, and the mid-channel areas between Seattle and the Kitsap Peninsula traditionally hold fish.

Adult chinook: MA10 adult chinook season timing varies by year and run strength. Early run fish (May-June) and later returning fish (August-September) both use the central Sound as a migration corridor. Strong tide rips at points and passages concentrate fish — the area around Point No Point, Shilshole, and the Richmond Beach area have historically been productive.

Coho: MA10 coho fishing peaks in September and October. Look for surface-feeding activity around large bait schools — birds working the surface in a concentrated area almost always indicate coho below. The shallower nearshore zones and areas near river mouths (Puyallup, Green River drainage) hold staging coho in fall.

Techniques for Puget Sound Salmon

Downrigger Trolling

The dominant technique for Puget Sound chinook and blackmouth. A flasher-and-hoochie or flasher-and-cut-herring combination at the target depth covers water efficiently and matches the active feeding behavior of trolling salmon.

Key depth ranges: Blackmouth 80-150 feet; adult chinook 60-150 feet; coho 15-50 feet. Use your sonar to find bait marks and start at bait depth.

Troll at 1.8-2.5 mph for chinook and blackmouth; 2.5-3.5 mph for coho. Green and chartreuse flasher colors are reliable year-round in Puget Sound's greenish water.

Mooching

Mooching is a traditional Puget Sound technique using a whole or cut herring presented on a two-hook mooching rig, with a banana-shaped sinker to provide weight and a slight rotating action. The boat drifts or moves very slowly as the bait spirals naturally through the water column.

Mooching produces exceptionally well for large chinook — the slow, natural presentation triggers strikes from fish that ignore faster trolling rigs. Depths of 80-160 feet are typical for mooching chinook.

Mooching rigs: 2-4 oz banana sinker on a 3-way swivel, with 30-36 inches of 20 lb mono to the top hook of a double-hook mooching rig. The top hook goes through the nose of the herring; the trailing hook is embedded in the body just past the dorsal fin.

Jigging for Coho

When coho are surface-feeding around bait schools, jigging is the most exciting and often most productive technique. A 1-2 oz metal jig in chrome, blue, or pink cast into the boil and retrieved quickly with an erratic motion produces violent strikes.

Buzz Bombs, Stingers, Point Wilson Darts, and similar cast-and-retrieve metal jigs are Puget Sound coho classics. Keep the retrieve fast and vary the depth — coho are chasing bait and will strike aggressively.

Herring Fishing

For blackmouth and chinook, a whole live or fresh herring fished near structure — either anchored near bottom or drifted through a productive zone — is a time-tested approach. Use a properly-rigged mooching rig or a simple hook-through-the-back-and-out-the-side rig. The herring swims naturally in the current, producing a tantalizingly lifelike presentation.

Reading the Sound: Finding Fish Without Local Knowledge

Tide rips: Current flowing over underwater points and ridges creates surface rips — disturbed, choppy surface water visible from a distance. Salmon stack at these rips to intercept bait carried by the current. Fish the edge of the rip, not the center.

Birds: Diving gulls and terns almost always indicate active baitfish schools below. Slow down and scan your sonar when you see bird activity.

Bait schools: Dense bait marks on your sonar — typically large blobs or curtains of marks in the water column — are the single most reliable indicator of nearby salmon. Marks at 30-60 feet indicate coho opportunity; marks at 80-150 feet indicate chinook and blackmouth potential.

Other boats: Concentrate of boats trolling slowly in a small area indicates a known productive zone. While "following the fleet" isn't always productive, it's a reasonable starting point when exploring unfamiliar water.

Regulations and Planning Tools

Puget Sound salmon regulations change frequently and are area-specific. The WDFW salmon season update page publishes current openings, closures, and quota status. The WDFW Fishing Hotline (360-902-2500) provides recorded weekly updates during salmon season.

Key things to verify before every Puget Sound salmon trip: - Is your specific marine area currently open? - What are the size limits and daily bag limits for each species? - Are wild fish of any species required to be released? - Has an emergency closure been announced?

Planning your trips around tide cycles also improves success. Moving tides (2-3 hours before and after high or low tide) generally produce better salmon action than slack tide periods. Strong tidal flows concentrate bait and keep fish actively moving and feeding.
