Charles River Watershed Association

Protecting, preserving and enhancing the Charles River and its watershed through science, advocacy and the law.

One of the country’s oldest watershed organizations, Charles River Watershed Association (CRWA) was formed in 1965 in response to public concern about the declining condition of the Charles. Since its earliest days of advocacy, CRWA has figured prominently in major clean-up and watershed protection efforts, working with government officials and citizen groups from 35 Massachusetts watershed towns from Hopkinton to Boston. Initiatives over the last five decades have dramatically improved the quality of water in the watershed and fundamentally changed approaches to water resource management.
