The Tryon Creek Watershed Council restores, protects and enhances the ecological health and function of our unique urban watershed. With headwaters in Multnomah Village and a watershed whose streams flow through both natural (20%) and urbanized (80%) areas, Tryon Creek flows through Portland and Lake Oswego, into the Willamette River. From there, threatened fish are able to find cool water refuge in Tryon Creek.
What We Do

We manage projects and coordinate partnerships to restore riparian native vegetation on streambanks, focusing on private properties along key wildlife corridors, neighboring green-spaces, and land adjacent to existing restoration sites. The Stone Bridge Culvert Replacement Project on Nettle Creek is an example of our work to remove fish passage barriers. We advocate for watershed health and support partners whose projects align with our mission such as the Boones Ferry Bridge and the Highway 43 Culvert projects. We monitor watershed health.

The majority of TCWC projects involve restoration of riparian native vegetation on stream banks. We focus these projects on private properties along key wildlife corridors, neighboring green-spaces, and adjacent to existing restoration sites.
From large projects with multiple landowners and environmental contractors doing on-the-ground work, to Saturday morning work parties, removing invasive species and planting native trees and shrubs helps to build a stronger ecosystem.
We work with community members, like you at weekend work parties.
Above: Stone Bridge before and after replacement – note the creek plunged an average of 3 feet, making upstream habitat inaccessible to fish. After the bridge replacement and channel restoration, the creek is more accessible to fish.

Volunteer Work Parties
Often on Saturday mornings, volunteer work parties are a great way for folks to get outside, students to earn service hours, businesses to represent themselves while team building, and often a fun way to spot a salamander! We regularly participate in No Ivy Day, Earth Day, and other regional annual events – our signature annual event is our Watershed Wide Event (below)!
Watershed Wide Event
Our Watershed Wide Event is the largest annual day of volunteering in the watershed. Community members start off the day getting fueled by coffee and breakfast snacks, celebrating, and then dispersing to various sites across the watershed to plant native plants and remove invasive plants.
Read about the annual Watershed Wide Event here, and mark your calendars for our 15th Annual Watershed Wide Event: Saturday, March 16th, 2024!
Watershed 101 Workshop
Tryon Creek Watershed Council provides this workshop, both indoors and hands-on, for watershed residents, who invite their neighbors, friends, and colleagues to attend. City of Portland’s Bureau of Environmental Services funds this program.
Pulling ivy isn’t for everyone – we host Science Talks twice annually at the Lucky Lab in Multnomah Village. We’re glad to be able to spread education through the watershed and the greater Portland area!
We hope to see you at one of our events!
