Volunteer in Miller and Walker Creeks
As a volunteer, you help make Miller and Walker Creeks better for people, fish, and wildlife. Thank you!
The volunteer projects listed below welcome people of all ages. Younger people may need their guardian present — please check with the event organizers. Unless otherwise noted, no experience is necessary. You'll learn on the job!
Forest restoration volunteers
- remove plants that harm forests, like English Ivy and Himalayan Blackberry,
- plant native trees, shrubs, and groundcover, and
- clean up litter.
2025 event dates coming soon!
Email the Basin Steward for more information.
CSI volunteers
- walk and wade through the lower mile of Miller Creek and Walker Creek during salmon return season (October through December)
- count live coho and chum salmon returning to Miller and Walker Creeks
- measure and dissect dead salmon to monitor pre-spawn mortality
Sign-ups for the 2025 salmon survey season will open in August 2025.
Email the Basin Steward for more information.
Much of the Miller and Walker Basin was developed before stormwater regulations. Development reduced forest cover and filled in wetlands. Urban development increased the amount of impervious surface in the watershed. Impervious surfaces are non-porous materials like concrete and asphalt.
When rain falls, it flows over the impervious surface instead of soaking into the ground. The water picks up pollutants, like oils or car tire particles, and runs off into storm drains or the surrounding landscape and creeks. This has led to negative stormwater impacts throughout the Basin. Flood flows have increased, resulting in erosion, flooding, and sediment deposition. Pollution from businesses, lawn care practices, and roadway runoff have degraded the creeks. Removal of streamside trees and shrubs have increased water temperatures.
Restoring forests and reducing pollution support healthy streams, salmon, and people.

Over 141 million acres of America’s forests are in cities and towns. Urban forests come in many different shapes and sizes. They include urban parks, street trees, landscaped boulevards, gardens, river and coastal promenades, greenways, river corridors, wetlands, and nature preserves.
Healthy forests are complex ecosystems with diverse plant and animal species. Shrubs and logs on the forest floor are home to wildlife and young and old trees provide cover and food. A healthy forest is resilient and resistant to insects, disease, and wildfire. Forests create microclimates that provide protection from warmer temperatures. They help mitigate the impacts of climate change by absorbing and storing carbon.
Urban forests
- absorb and filter rainwater (which helps streams, salmon, and orcas!)
- provide clean oxygen and filter pollutants from the air
- create living space for wildlife
- are a place where people can connect with the outdoors
- provide mental health benefits
- build resilience for a changing climate
We count numbers of adult coho and chum salmon to determine how many fish return to the creeks each year. We can use these data to look at population trends over many years. This helps us understand how ocean conditions and freshwater habitat conditions affect salmon.
We measure and dissect dead salmon to learn how many salmon die before they have a chance to spawn. Coho salmon pre-spawn mortality has been linked to polluted road runoff. Through the CSI program and partnerships with scientists at University of Washington, Washington State University, and the USGS Western Fisheries Research Center, Miller Creek has become an important watershed for research on water quality and coho mortality.
The data we collect through the CSI program informs restoration priorities. It helps us track progress: are Miller and Walker restoration efforts helping salmon?

In addition to the Miller-Walker Basin Stewardship Program, many local organizations offer volunteer opportunities.

Stewardship of the Miller and Walker Creeks basin is jointly funded by the City of Burien, City of Normandy Park, City of SeaTac, King County, and the Port of Seattle. On behalf of the partners, this page is proudly hosted by King County Department of Natural Resources and Parks - Water and Land Resources Division.
