South Shore Region

The South Shore Region includes the communities of Cohasset, Scituate, Norwell, Hanover, Marshfield, Pembroke, Duxbury, Kingston, and Plymouth.

MassBays' South Shore region encompasses nine communities from Cohasset to Plymouth, including six within the North and South Rivers watershed. The North River was the first designated scenic river in Massachusetts. It is a tidal river home to river herring.The South River is a 15-mile river flows through Duxbury and Marshfield, and is a tidal estuary to the first dam, 8.8 miles from Massachusetts Bay. The South River has an active river herring run as well as pockets of isolated Eastern brook trout in headwater tributaries. The region is characterized by extensive beaches and marshes, frequented by wildlife watchers and recreational boaters. A thriving shellfishing industry characterizes some of the towns including Duxbury.
