Spoiler alert: We are using all the water we'll ever have. Whether it comes from a river, lake or melting snowpack, our water is part of a closed system—one water. This one water has been used before and will be used again.
A watershed is like a great big bowl linking land, water, and people. Our Tualatin River watershed drains 712 square miles and ranges from densely populated areas to agricultural areas and the forests of Oregon’s Coast Range.
Enhancing the environment and quality of life in the Tualatin River Watershed through visionary and collaborative management of water resources in partnership with others.
