We strive to make the Charles River and its parks a well-maintained network of natural urban places that invite and engage all in their use and stewardship.


With the help of our supporters, we had a great year getting back to volunteering, investing in unique ecological programs, and centering our work on the communities around the Charles. Check out our FY21 Annual Report for our year in review.

Our May E-newsletter is out! Give it a read to learn about the latest CRC happenings and review past E-newsletters.

We are thrilled to welcome three new members to our board: Simeen Mohsen, Nayeli Rodriguez, and Laurel Schwab. Learn more about them here.

Our work depends on equity, and we therefore cannot stay silent to racism and police brutality. Read our statement of solidarity with Black Lives Matter protestors in Boston and around the country.

Registration for City Splash and the Afterparty is open! Swim slots are currently full, but you can still sign up for the waitlist and register for on-land activities. You need to register for each event separately. Spots are limited, and the event fills up fast!

23rd Annual Earth Day Charles River Cleanup

Watertown High School ESL picked up litter around Watertown Square along the Charles River for Earth Day.

Thanks to our volunteers and sponsors for attending our Earth Day Charles River Cleanup! We can’t wait to share the numbers that show how much of an impact you made on the parks. From North Point Park to Watertown Square, you gave back to our public spaces and helped us keep them clean for the benefit of us all. If you weren’t able to join us this Earth Day, please consider scheduling a volunteer event with us as the parks need care throughout the year!
