For over 20 years, Barnstable Clean Water Coalition (BCWC) has worked with the University of Massachusetts Dartmouth’s School for Marine Science and Technology (SMAST) collecting water samples and associated water quality data in the Three Bays estuary. The Massachusetts Estuary Project reports that the 1,251-acre Three Bays estuary that includes West, North and Cotuit Bays exceeds a critical threshold for nitrogen that is harmful to water quality, human health, and is toxic for wildlife and plant life.

Barnstable Clean Water Coalition (BCWC) is responsible for co-managing Dead Neck Sampson’s Island with the Massachusetts Audubon Society. In this video, learn about the history of DNSI, the variety of shorebirds that nest on the island, and how BCWC educates island visitors about this fragile barrier island and its winged inhabitants.
