The Herring Ponds Watershed Association (HPWA) was established in 2007 as a volunteer neighborhood association.
Our focus is health of all the water in our watershed : the groundwater we pump and use in our homes, the water in ponds and streams we enjoy for recreation, and that used by native plants and wildlife in our neighborhoods and ecosystem.
HPWA works to raise awareness of the importance and fragility of our state-designated Area of Critical Environmental Concern (ACEC), to protect and preserve the ponds and watershed through citizen science and education.
Our ACEC encompasses 4,450-acres in southern Plymouth and Bourne, including 11 ponds (the largest, Great Herring is 376 acres), two rivers, numerous freshwater wetlands, productive cranberry bogs, an important and active herring run, and over 250 acres of protected open space.
Our all-volunteer efforts include regular water quality sampling, supplemental runoff event sampling, flow gauge reporting, and public educational programs. We also created The Herring Ponds Watershed – Your Stewardship Guide, featuring information on the water cycle, ponds, wildlife, history, and emphasizing tips for sustainable living in and protection of the watershed.

Since that time, we have maintained an increasingly consistent level of effort to educate others and ourselves about this small coastal ecosystem and its relationship to the globally significant Gulf of Maine. In 2011 we took down the middle dam on Jones river, and In 2012 we joined forces with others to launch the Cape Cod Bay Watch Campaign to correct the destructive impacts from the cooling water intake structure at the Pilgrim Nuclear Power Station and develop a network to protect the species, habitats and health of the bay.
