Muddy River Cleanup 2022

We hope you will join us for this year’s Muddy River Cleanup!

The Muddy River Cleanup is a part of the Annual Earth Day Charles River Cleanup; this event takes place throughout the Charles River Watershed and 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.​

The Charles River Cleanup brings together over 3,000 volunteers each year to pick up litter, remove invasive species and assist with park maintenance along all 80 miles of the Charles 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 to exercise, play and enjoy nature throughout the year.

Each volunteer team will fill out a form reporting how many pounds of trash they collected and what items they found.
