How Healthy is Your Water?

Starting at Halfway Pond in Plymouth, the freshwater Agawam River flows through forests and cranberry bogs on its way toward Wareham. The Agawam River is home to one of Buzzards Bay’s largest populations of river herring, which migrate upstream each spring to spawn in fresh water. The weir at Route 28 separates the freshwater portion of the Agawam River from the tidal estuary.

Agawam River – Fresh Snapshot

The Buzzards Bay Coalition does not calculate a Bay Health Index score for Agawam River – Fresh because it is a freshwater location. The Bay Health Index is only used to measure the health of coastal waters, including harbors, coves, and tidal rivers.
