River Restoration Northwest is a nonprofit scientific and educational organization. Our mission is to advance the science and standards of practice of river restoration through an interdisciplinary approach.

Our organization formed in response to the February 2002 Northwest Stream Restoration Design Symposium. Strong participation in the meeting highlighted the need for an interdisciplinary forum for river restoration professionals.

Mission & GoalsHistoryBoardMembersDocuments


River Restoration Northwest seeks to advance the science and standards of practice of river restoration through educational programs that emphasize an interdisciplinary approach to promote responsible practices, discuss and exchange ideas, assess projects, reflect on lessons learned, and provide technology transfer.


Our organizational goals are to:

  • Promote responsible practices in the design of river restoration projects.
  • Enhance discussion and exchange of ideas between river restoration professionals with different disciplinary backgrounds including: aquatic and fisheries biology, geomorphology, landscape architecture, hydrologic and hydraulic engineering, wetland science, and soil science.
  • Provide a forum for project assessment and reflections on lessons learned.
  • Create opportunities for professional development and technical information exchange.
  • Provide technology transfer from research to practice.

We are excited to welcome new members and encourage you to share your ideas for the organization.

In August 2001, a group of Oregonian river restoration professionals met in the Reno airport on their return from a national wetlands and river engineering conference. They were struck by the need for a regional forum for design professionals and decided to organize a symposium. With hard work and good luck, the symposium came together within a few months. The first Northwest Stream Restoration Design Symposium was held in February 2002 at Skamania Lodge in Stevenson, WA. The symposium was enthusiastically attended by more than 200 engineers, biologists, hydrologists, and other stream restoration professionals.

In response to this success, the original “airport founders” (and others they’d enlisted along the way), decided to establish RRNW. We incorporated in Oregon as a 501(c)(3) non-profit organization in May 2002. We received Federal tax-exempt status from the IRS in 2003. We look forward to welcoming new members and expanding the activities of the organization!
