Join Columbia Slough Watershed Council for the annual Great Slough Cleanup! This year we will be working in 3 different locations to remove trash from in and around the Slough.

Join us for our on land efforts to remove trash (location details coming soon), or join us on the water at Whitaker Ponds or from a launch located at NE Glassplant Rd & NE Alderwood Rd. Participants can reserve a seat in one of our boats, or bring their own.
