The Columbia Slough Watershed Council is a diverse 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.

Through partnerships and action we work towards Our mission: to foster action to protect, enhance, restore and revitalize the Slough and its watershed. The Council's first meetings were held in 1994, and the Council was incorporated as a 501(c)(3) non-profit in 2000.
