From the organizers of Mystic River Watershed Association:

"The Mystic River Watershed Association (MyRWA) was founded in 1972 to protect and restore natural resources in the 22-community watershed. MyRWA accomplishes this work through the efforts of professional staff and thousands of volunteers working together on a project-by-project basis."

Volunteers undertake projects like water-quality monitoring, herring counts, water chestnut removal and tracking hazardous-waste cleanup at the Boston Harbor Casino site.

MyRWA held an open-house on June 14 to kick off their greenway plan for the Malden River waterfront

Sounds like an admirable organization making a valuable contribution to Boston tourism. If you live in the area, why not volunteer?
