Resilience is Key to a Healthy Tualatin River Watershed

Climate change, drought, deforestation, emerald ash borer, urban growth - these are just a few of the challenges facing our ecosystem now and into the future.

We don't know what the long-term impacts of these disturbances on the Tualatin River and our watershed will be. We do know that we have a responsibility to do all we can to ensure that these changes have as minimal an impact as possible on our beloved watershed.

Our Work to Create a More Sustainable, Resilient Watershed

Urban Growth Management

Our region is facing a housing crisis, and it’s imperative that we all do our part. We will not, however, sacrifice watershed health in service to hasty urban planning. Tualatin Riverkeepers is continuing to monitor and comment on threats to the river and our watershed, such as King City’s proposed Fischer Road extension and Washington County’s Tile Flat Road connection. We’re also working with neighbors and advocates as Cooper Mountain's Urban Growth Boundary project is being planned near Cooper Mountain Nature Park. As growth continues in this part of the county, we will work with residents and local governments to advocate for and coordinate land acquisition to expand the park.

Forest Health

The Tualatin River provides drinking water to more than half a million people, making the health of the Coast Range, particularly Tillamook State Forest, critical for the future of our watershed. As the Oregon Department of Forestry continues to consider a Western Oregon State Forest Habitat Conservation Plan, we are committed to working with partner organizations to support a plan that is science-based and conservation-focused. Similarly, we will consistently monitor and report forest practices on public and private lands that are detrimental to watershed health and in opposition to the Clean Water Act.

Community Education

Pint-Sized Science is our popular speaker series focusing on innovative science and natural climate solutions being used to improve watershed health. We thank our community partners for their expertise and our friends at Tualatin Soil and Water Conservation District for their sponsorship of this series.

Restoration Work

Volunteer-led restoration work is central to fulfilling our mission, and we continue to build partnerships with land managers throughout the watershed. Many of our restoration projects support previous advocacy work, such as the removal of Balm Grove Dam on Gales Creek. The dam, recently removed after years of advocacy, will allow species such as pacific lamprey to migrate upstream once again in Gales Creek. TRK volunteers will be working with our partners from Friends of Trees and Clean Water Services to plant native species and create habitat in the area around where the dam was removed. Get involved in our restoration and stewardship work!

River Runners

The River Runners are a group of Tualatin Riverkeepers’ paddlers who serve as the eyes of the river. Each River Runner, or small group of River Runners, adopts a specific section of river. They paddle that section on a quarterly basis, gathering and reporting on threats to the health of the Tualatin – invasive species, agricultural runoff, pollution, and erosion concerns – and any potential navigability issues. If you are interested in becoming a River Runner volunteer, email us at

Sustainable Land Use
About 35% of the Tualatin basin is made up of agricultural land. The management of agricultural runoff and waste is important to keeping the waters clean. See this link for management suggestions on mud, manure, and pastures.

Harmful Algal Blooms
Harmful algal blooms are caused by a combination of high nurtrient load, warmer water temperature, and low flows, and can harm human health and aquatic life if not addressed accordingly. Please do your part to help identify and mitigate harmful algal blooms!
