History of the Charles River Cleanup
The Annual Earth Day Charles River Cleanup was started by the Charles River Watershed Association in 2009, in an effort to clean-up the river. It builds on a national effort as part of American Rivers’ National River Cleanup®, which to date, has removed over 25 million pounds of trash from America’s waterways. From 2016 to 2019, the Annual Earth Day Charles River Cleanup was recognized by American Rivers for the Most Pounds of Trash Collected and Most Volunteers Mobilized.
Our Cleanup brings together over 3,500 volunteers each year to pick up litter, remove invasive species, and assist with park maintenance along all 80 miles of the Charles River and the 1,100 acres of Emerald Necklace park land surrounding the Muddy River. Residents are drawn to the popular Charles River Cleanup from a desire to give back to their community while enjoying the beauty and wildlife along the river. Volunteers hold onto the connections they establish during this day of stewardship by returning to the Charles and Muddy Rivers to exercise, play, and enjoy nature throughout the year.
