Weir River Estuary

"Its where the river meets the ocean."

Native Americans hunted and fished the Weir River Estuary for thousands of years. The Plymouth Colony began trading with the local Native Americans as early as 1621.

Here, you will find undisturbed salt marshes and a unique habitat that supports over 100 different species of migratory and breeding birds.

These waters are special for the breeding and nurseries for many species of fish. In the 1880's Hull was well known for its smelt fishery and the Weir River supported one of the largest smelt runs in the state.

The estuary is among the most productive shellfish beds in Boston Harbor. Soft shell clams, blue mussels, and American oysters can be found along the tidal flats.
