Every Fall, Wild Salmon Swim Home to a Creek Most of Normandy Park Drives Over

Drive down 1st Ave S past the QFC and you will cross Miller Creek without ever seeing it. The culvert is easy to miss, a concrete pipe under a residential street, the kind of infrastructure detail nobody notices until someone points it out. But for about ten weeks every fall, that creek and its sister stream, Walker Creek, fill with wild salmon fighting their way back from Puget Sound to the same gravel beds where they hatched three years earlier.

This is not a metaphor for neighborhood character. It is a literal, monitored, counted salmon run, moving through one of the more built-out residential pockets in King County, and a volunteer program has been tracking it since 2010. Most residents who live within walking distance of Miller or Walker Creek have never seen it happen. That is the gap this post is here to close.

What's actually returning, and when

Miller Creek and Walker Creek both start inland, cut through Burien and SeaTac, and empty into Puget Sound through Normandy Park. Two species make the trip back up these creeks each fall: coho and chum salmon. They do not arrive on the same schedule, and knowing the difference is the whole trick to timing a walk down to the water.

Species Typical window in Miller and Walker Creeks
Coho salmon Mid-October through mid-November
Chum salmon Mid-November through early December

Coho are the first wave, and by the time they are winding down, chum are moving in behind them. The full season runs roughly from early October into late December, which is also the exact window when the local monitoring program is out on the water counting fish. That is not a coincidence. It is the same ten weeks, every year.

Where to actually stand

You do not need waders or a survey clipboard to see this. Three spots do the work.

Walker Preserve, on the Normandy Park side, has recently become one of the newer stewardship sites for the creek's volunteer program and is an easy, unhurried place to watch the lower stretch of the creek without wading into it yourself. Miller Creek Trail, just over the line in Burien, gives you a longer stretch of creek to walk alongside. And if you want to see where all of this water actually lets out, the outlet near the Cove, the Normandy Park Community Club property at the west end of SW Shorebrook Drive, sits right where Walker Creek meets Puget Sound. The Cove's own duck pond, tucked behind the clubhouse, is managed as rearing habitat for young coho, so the fish story here does not stop with the adults swimming upstream. It starts with juveniles growing up in that pond long before they ever head out to sea.

None of these are secret locations. They are just spots nobody thinks to visit unless they already know what is happening underneath the surface each fall.

The count that turns a walk into data

Here is the detail that changes how you look at that creek: this is not casual wildlife-watching. It is one of the longer-running citizen science programs in the county.

Since 2010, volunteers with the Community Salmon Investigation, known as CSI, have walked and waded the lower mile of Miller and Walker Creeks every week during return season. Teams count live coho and chum, then measure and dissect the ones that did not survive to spawn, logging what is called pre-spawn mortality. In 2023, that effort turned up 117 live fish and 57 carcasses examined for spawning success, alongside 113 native trees and shrubs planted and 9,000 square feet of streamside habitat restored by volunteers that same year.

The reason this counting matters gets at something specific about this basin. Much of the Miller and Walker watershed was built out before modern stormwater regulations existed. Rain that falls on roofs, driveways, and streets does not soak into the ground the way it would in an undeveloped watershed. It runs straight into the creek, carrying oil, tire particles, and other road pollutants with it. Researchers working with the University of Washington, Washington State University, and the USGS Western Fisheries Research Center have linked that runoff directly to coho dying before they can spawn, a pattern serious enough that this small urban watershed has become a genuine research site for understanding pollution and pre-spawn mortality more broadly.

That is the real story underneath the culvert on 1st Ave S. This is not a pristine, undisturbed stream. It is a working, damaged, actively-monitored watershed that still produces a countable salmon run every year, inside a neighborhood built up decades before anyone thought to ask what all that pavement would do to the water underneath it.

How to actually get in the water this fall

If watching from the bank is not enough, the program is recruiting right now for the 2026 survey season, and the timing lines up well with where we are on the calendar. Training is planned for late September, open to anyone regardless of prior experience. Volunteer teams of two or three are assigned a single day of the week and walk their stretch of creek on that day throughout the season, counting fish and logging what they find.

Two habitat events round out the fall calendar this year: a tree-planting day on November 7 at Miller Creek Trail, and another on December 5 at Walker Preserve, both running from 10 a.m. to 1 p.m. and open to residents who want to help restore the streamside forest that keeps the water cool and shaded for returning fish.

The program is a partnership between the cities of Burien, Normandy Park, and SeaTac, King County, the Port of Seattle, and the Mid Sound Fisheries Enhancement Group, which runs the volunteer sign-up and training. Anyone with questions about joining can reach the program's Basin Steward, Piper Hanson, through the King County watershed volunteer page, and current sign-up details are posted on the Mid Sound Fisheries Enhancement Group's salmon survey page.

What this actually says about the neighborhood

It would be easy to treat this as a nice-to-know seasonal footnote, the kind of thing you file away and forget by November. But the fact that Normandy Park still hosts a monitored, functioning salmon run, tracked continuously since 2010 through one of the most developed corners of King County, says something real about the place. It is not wild in the sense of untouched. It is wild in the sense that something kept coming back anyway, and a group of residents decided that was worth counting.

The next time you cross 1st Ave S near the QFC, the creek is still down there, and sometime around mid-October, so are the fish.
