Marys River Watershed Council MRWC works to inspire and support voluntary stewardship of the Marys River watershed in Oregon. The results inspire us.

Our Vision
From Marys Peak to the Willamette River from forests to farms, prairies to ponds, backyards to school yards, we’re cultivating strong neighborhood ownership of the watershed’s health. We envision a future where abundant native fish live in the shaded creeks and rivers of our watershed. People feel connected to this place and see themselves as active stewards of the land and water. Investing in voluntary partnerships, the Marys River Watershed Council is a catalyst for restoring natural systems in a resilient watershed. Our Purpose
Our purpose is to inspire and support voluntary stewardship of the Marys River watershed. Our Guiding Principles

We believe that a healthy environment and a healthy economy are inextricably linked. We believe that watershed stewardship should be based on a combination of sound science, education and community involvement. We believe that a strong stewardship ethic enables us to leave healthy natural resources for future generations. We believe in working from ridge to ridge to achieve dynamic, naturally functioning ecosystems. We value our relationship with the landowners who have voluntarily joined in whole watershed habitat enhancement projects. Our Membership
Membership is open to any individual who supports the purpose and guiding principles of the Marys River Watershed Council and who lives in, works in, plays in, derives benefit from, or is affected by the watershed and its resources, and who has paid annual dues.

Join staff from Benton Soil and Water Conservation District and Greenbelt Land Trust to learn how even a small backyard can contribute to large-scale habitat connections and ecosystem health. In this time of increasing droughts, shifting seasons, and declining biodiversity, home gardens can play a major role in community-wide adaptation and resilience. We’ll discuss the climate-driven changes we’ve observed in our own local ecosystems, and how you can respond and evolve at home with highly adaptable native species.

Graduate students Jessica Blunn and Katherine McCool will take us on a journey in soil science by sharing the planning and sampling process for obtaining large collections of forest soils. They will then share their individual lab and statistical analyses used to answer important questions in Western Oregon fire ecology, including the determination of historic landscape ecology and fire histories and understanding compound disturbance effects on forest soil health.

Exciting news: the first of our NOAA-funded fish passage projects is COMPLETE!

Check out the early days of the project in this video: clearing the site, digging out the roadway, and conducting fish salvage. A lot of the construction time on these projects is moving dirt around, just like you did in the sandbox as a kid (well, kinda).

Take a look at our newsletter to learn more about the project!

How to Use GIS to Achieve Conservation Goals
This month we will hear from Chris Beatty, who is volunteering with local nonprofits to apply GIS tools to reach conservation goals. He will be talking about how he uses DOGAMI LiDAR and other web-based mapping tools to scan the forest canopy across Oregon. Using these tools for analysis helps us better understand stand age and other characteristics.
