Columbia Slough Watershed Council


To protect and enhance the Columbia Slough and its watershed through community engagement, education, and restoration. 

Bottom Line for Portland

Through strong community partnerships and engagement CSWC provides FREE programming throughout the year, including 100+ community paddles, workforce development, and stewardship events, installing 10,000 native plants, and providing free environmental education to 1,200 K-12 students.  This programming is unique and not offered elsewhere in the Portland Metro area. We intentionally partner with schools and organizations to reflect the watershed’s diverse community.

Diversity, Equity, and Inclusion

Our watershed is home to the most diverse communities in the Metro area.  We prioritize partnerships with community groups that are representative of the watershed. We work with our partners to address and remove barriers so everyone can access and enjoy being outdoors. These partnerships include multilingual birding and canoeing events (Spanish, Ukrainian, Russian and Zomi), BIPOC specific workforce development opportunities, LGBTQIA+ specific community opportunities, and educational opportunities for Title I schools throughout the watershed.
