Cheers to 60 Years! Sunset Soirée

On September 16, we celebrated CRWA's 60th birthday by cruising Boston Harbor with many of the friends and supporters who make our work possible. We want to extend a heartfelt thank you to the incredible volunteers, advocates, and donors who work alongside us to protect, restore, and enhance the Charles. We have made great strides since CRWA was founded in 1965, and while the work is not done, the story of the cleanup of the Charles is a reminder that we humans can do extraordinary things when we put our minds to it.

CRWA in the News:

Fed up, groups demand solution to sewage overflows (SHNS)

Since launching our Cut The Crap campaign in April, we have been collaborating with fellow watershed organizations to raise public awareness and advocate for the elimination of combined sewer overflows (CSOs). Eliminating CSOs would not only improve water quality and public health, but would fulfill the promise of the Clean Water Act of 1972 and the Clean Charles Initiative of 2005. Thank you to the State House News Service for this article highlighting our efforts.

CRWA and Milford Secure $600K Grant to Restore Godfrey Brook

We’re thrilled to announce that, in partnership with the Town of Milford, we’ve secured nearly $600,000 in funding through the Healey-Driscoll Administration’s Municipal Vulnerability Preparedness (MVP) Action Grant Program to lead flood mitigation and climate resilience work in the Town’s Godfrey Brook subwatershed. This will fund a multi-year effort to study and address flooding and water quality challenges along Godfrey Brook and its tributaries, Hospital and O’Brien Brooks. As part of the project team, CRWA will assess existing brook conditions and propose and design nature-based solutions, such as wetland restoration, floodplain reconnection, and stream daylighting. This project will yield permit-ready designs for priority projects that will safeguard residents, businesses, and infrastructure from worsening climate-driven storms, while also enhancing the ecological health of the Charles River.

Charles River Watershed Reenters Significant Drought

We're seeing low water levels across the watershed, and earlier this month, the Commonwealth declared a Level 2 Significant Drought for parts of the Charles River watershed and a Level 1 Mild Drought for the remaining watershed area. When we look at precipitation, we see that rainfall isn't far off the year-to-date average; in fact, statewide, 2025 has been rainier than average. In Boston, we are about 3 inches behind the cumulative average for this time of the year, but why are these typical variations from the average leaving us with completely dry riverbeds? Read our blog post to find out.

What Massachusetts’ New Biodiversity Plan Means for Charles River Watershed Residents

Last month, Governor Healey announced a nation-leading 25-year biodiversity initiative to help restore rivers, forests, and habitats across the state. This first-of-its-kind executive order claims it will halt and reverse biodiversity loss in the Commonwealth, promising to “rebuild biodiversity and invest in nature to sustain our health and well-being, food security, economy, and way of life.” This plan represents a significant step toward Massachusetts' climate goals; however, this order is only as powerful as its implementation. We’ve dug into the 36-page report and have some key takeaways to share.

Canterbury Brook Restoration Kick Off (on wheels!)

Thank you to everyone who joined us at Chez Vous in Dorchester for rollerskating and pizza as we kicked off a long-term, community-driven vision plan for the restoration of Canterbury Brook and its surrounding land. We received invaluable feedback that will help shape the next steps. If you’re a Mattapan resident and would like to share your preferences on the restoration process, we encourage you to take the survey and share it with other residents in your community.

If you missed the restoration kickoff or would like to learn more, join us on October 18 for a family-friendly guided walk along Canterbury Brook. You’ll learn how to catalog flora and fauna using iNaturalist, hear about river restoration, and collect vital community science data.

Life in Cheesecake Brook

Earlier this month, we hosted a “BioBlitz” biological survey at Cheesecake Brook in Newton. Participants logged 257 observations of 74 different species, including both native species, like American Asters (Symphyotrichum), and many that are characteristic of altered urban environments (Sheep's Sorrel (Rumex acetosella).


Later, CRWA’s Max Rome and Alfredo Con joined the Native Fish Coalition (NFC) on a “fishing trip” at Cheesecake after discovering that fish from the Charles River were finding their way into the stream, despite a large cement slab that blocks most fish passage. Together, NFC and CRWA were excited to confirm that the brook can sustain aquatic life! We fully expect that biodiversity in the brook will only improve as the restoration project there is constructed.
