Dedicated to protecting and restoring Waquoit Bay and its watershed


CPWB has a long and productive history.  It was started in 1981 by Falmouth attorney and former planning board member, Winnifred Woods and Mashpee resident Deborah Moore to successfully prevent the development of Washburn Island.  Later, under the same leadership, it lobbied successfully for the protection of South Cape Beach and the founding of the Waquoit Bay National Estuarine Research Reserve.

In 1987, under the leadership of Matt Patrick and Donald Bourne, CPWB assembled a group of civic and environmental organizations known as the Quashnet Coalition to convince the Commonwealth to acquire the Quashnet River Valley, where a large condominium project had been proposed.  Later under Patrick and Bourne, CPWB became one of the founding sponsors of the Coalition for the Cape Cod Commission, the land use authority that has made Cape Cod a better place to live.  All of these achievements would not have been possible without civic minded people like you who became members and supported these efforts.

NOTE:  CPWB was the prime mover in making this study happen contributing $2500 to the total cost of the study, convincing the Towns of Mashpee and Falmouth to kick in $9,135 each to cinch the arrangement. The Cape Cod Water Collaborative contributed the majority of the funding, $21,750, under the condition that the balance was picked up by the Towns and CPWB.  The Mashpee Environmental Council added $500.


“I have lived on Waquoit Bay my entire life. Over the decades I have seen the condition of the Bay’s waters deteriorate. I want to do something about that.  CPWB is for me the key.  For years, CPWB has been a voice for the Bay. Here I can join others who care about the Bay to raise awareness and advocate for change, both personal and institutional, that can save the Bay.”  Winthrop Munro

“I have been a member (of CPWB) since the early days, as was my husband, serving on the Steering Committee much of the time. Living on Waquoit Bay has made CPWB important.”  Jayne Abbott
