The Tualatin Watershed Enhancement Collaborative (TWEC) links land, water and people. We bring together all interests in the basin to promote and improve watershed health. We work together through cooperation, collaboration and communication. All of our actions affect the health of our watershed. We need your help in improving our watershed’s health!

TWEC is a continuation of the work that started with the Oregon Solutions Cedar Mill Creek Flood Remediation Collaborative effort. That effort culminated a three-year work program that created the TWEC governance, as well as its focus on flooding resiliency, environmental improvement and financial security within the Tualatin Watershed.

TWEC’s first project is the Cedar Mill/North John Creek Basin, the basin that was the impetus for the organization’s development. The project included a robust public engagement process. People living in the basin submitted photos of flooding and shared experiences with eroding creek banks, falling trees and flood insurance. This information was used to develop potential strategies to mitigate the flooding and preserve the integrity of the watershed.
