Sea-run Cutthroat Trout
Sea-run cutthroat — called “harvest trout” by old-timers and “searuns” by those who chase them obsessively — are one of the Pacific Northwest’s most underrated fly fishing targets. These coastal cutthroat spend part of their lives in saltwater before returning to freshwater rivers and estuaries, where they can be found in surprisingly accessible water close to Portland and throughout coastal Oregon and Washington. Aggressive, acrobatic, and beautiful, searuns are a PNW fly fishing treasure.
Seasons & Prime Waters
Sea-run cutthroat fishing peaks in late summer and fall (August through November) as fish move back into freshwater. Tidal estuaries and lower river reaches can hold fish year-round. Key waters include:
- Tillamook Bay tributaries — Wilson, Trask, Kilchis, and Miami rivers; excellent fall searun fishing
- Nestucca River — one of Oregon’s premier sea-run cutthroat rivers
- Siletz River — strong runs of searuns in the Coast Range
- Alsea River — a productive coastal river with good access
- Clackamas River — accessible sea-run cutthroat water close to Portland
- Oregon coastal rivers — virtually every coastal stream from the Columbia to the California border holds sea-run cutthroat; explore and discover your own water
- Washougal River (WA) — excellent searun cutthroat in the Columbia Gorge region
- Cowlitz River (WA) — strong sea-run cutthroat runs in Southwest Washington
- Lewis River (WA) — productive searun water in Southwest Washington
- Willapa Bay tributaries (WA) — excellent searun fishing in Southwest Washington
- Chehalis River system (WA) — strong sea-run cutthroat populations
- Puget Sound beaches (WA) — saltwater beach fishing for searuns is a unique and exciting experience
Recommended Gear
Sea-run cutthroat are accessible fish that don’t require heavy gear, but quality tackle makes a difference.
Rods
A 9-foot 5 or 6-weight is the versatile choice for searuns — light enough for delicate presentations in low clear water, with enough backbone for estuary and tidal fishing. For Puget Sound beach fishing, a 6-weight with a saltwater reel is ideal.
Reels & Lines
A weight-forward floating line handles most freshwater searun situations. For estuary and beach fishing, an intermediate or slow-sink line gets flies into the strike zone. If fishing in saltwater, use a reel with a sealed drag to resist corrosion.

Leaders & Tippet
A 9-foot 4X or 5X leader works well in freshwater. For estuary and saltwater fishing, shorten to 7-8 feet and use 8-10 lb fluorocarbon — searuns aren’t particularly leader-shy in tidal water.
Waders & Boots
Breathable waders are essential for coastal river fishing. For Puget Sound beach fishing, neoprene or breathable waders with felt or rubber-soled boots handle the varied terrain.
Flies That Work
Sea-run cutthroat are aggressive and opportunistic — they’ll eat a wide range of patterns.
Freshwater & Estuary Patterns
Rolled Muddler, Spruce Fly, Comet, Soft Hackle Wet Flies, Woolly Bugger (olive, black, white)
Beach & Saltwater Patterns
Clouser Minnow, Deceiver, Surf Candy, Chum Baby — small baitfish imitations in silver, white, and chartreuse
Dry Flies
Elk Hair Caddis, Stimulator — searuns will rise aggressively in low clear water
