Join the Columbia Slough Watershed Council and our Partners, Hydro, for an on-water cleanup of the Columbia Slough in NE Portland. We'll launch from Whitaker Ponds and canoe down to the Hydro facilities off of the slough. On the way out, and back we'll pick up all kinds of trash from microplastics to macroplastics. Work gloves, trash bags and trash pickers will be provided for you. Be prepared to get dirty!
