Since 1989, AWS has mobilized thousands of volunteers and supporters to plant trees, stencil storm drains, restore wetlands, pick up trash, write letters, make phone calls, paddle canoes and kayaks, ride pontoon boats, participate in rallies, hike, bike and walk, remove invasive plants, stabilize stream banks, watch slideshows, visit local landmarks, row, and much more, all in the name of returning the Anacostia River and its surrounding communities to a clean and healthy condition.
