Columbia Slough Watershed Council

The Columbia Slough Watershed Council is a 501(c)3 nonprofit organization founded in 1994 with an annual budget of about $500K. The Council’s mission is to protect and enhance the Columbia Slough and its watershed through community engagement, education, and restoration. The Council is a diverse and highly engaged group of neighbors, property owners, businesses, environmental groups, recreation advocates, and government agencies who work to restore and enhance the 60 miles of waterways, wetlands, and slow-moving channels known as the Columbia Slough. The watershed spans from Kelley Point Park to the west through Gresham and Fairview to the east, covering aquifers relied upon by the populations of Portland, Gresham, and Fairview.
