Environmental Concerns for the Weir River


Because of Weir River’s unique ecosystem of tidal and non-tidal sections, it is especially susceptible to shifts in nutrient balances. As a result, the river has been declared a critical environmental concern by the State of Massachusetts in 1986. Click here to learn more. The Weir River also suffers from low flow conditions during dry summers.




Additional Facts


History: The Weir River watershed was an important economic center during colonial times. The Plymouth colony started trade with Native American inhabitants of the Weir as early as 1621 and the towns of Hingham and Hull were incorporated in 1635 and 1644, respectively. These colonies were based mostly around marine activities, such as fishing. Later on, industry took hold in both towns. In the 19th and 20th centuries, the towns of Hingham and Hull became more tourism-oriented as industry and fishing declined. The river was dredged from Foundry Pond (which divides the tidal and non-tidal sections of the river) to Main Street in the mid-1950s as an effort to control flooding. Did you know? The Weir River is home to the pied-billed Grede (Podilymbus podiceps), which is an endangered species.





What Are People Saying?

“Most challenging thing about working on the Weir River is the public has little appreciation for it so it is not high on the list of things to be concerned about. The river suffers from no and low flows due to over withdrawals in the summertime but it is not something that people see the impacts of or seemingly care about preventing.”

“My favorite memory of the Weir River is paddle boarding at dawn on an incoming tide and seeing an eagle and an osprey on the same trip!”
