A pair of grants from the Massachusetts Environmental Trust (MET) were recently awarded to protect Third Herring Brook and the South River, both on the South Shore.


Restoring the Third Herring Brook 

The North and South Rivers Watershed Association was awarded $28,500 to document, scientifically monitor and tell the story of the physical and biological response of the Third Herring Brook river system after removing the Tack Factory Dam. The Third Herring Brook restoration project, which is a Massachusetts Division of Ecological Restoration Priority Project, has been an ongoing effort over the last 10 years that reached a critical milestone this past December with the removal of the Tack Factory Dam, the second dam to be removed on this brook, reconnecting 8.4 miles of the Third Herring Brook to the North River, which flows into Massachusetts Bay.

This project will measure the success of river restoration efforts on the Third Herring Brook after the removal of the Tack Factory Dam and provide a video that showcases restoration efforts from early inception to measuring success as a model for other communities. Our goal with this project is to document, scientifically monitor, and tell the story of the physical and biological response of the Third Herring Brook river system after the Tack Factory Dam was removed and more than 8 miles of instream habitats become undammed, allowing river herring and Eastern Brook Trout to move and migrate freely.


Restoring the South River

The Town of Duxbury was awarded $10,000 in support of a study to understand the effects that removing the Temple Street dam might present. This project is a step in a series of steps that has been taken by the NSRWA and the towns of Marshfield and Duxbury to restore the South River’s health. In 2014 the NSRWA and its partners – Massachusetts Bays Program and the Towns of Duxbury and Marshfield – successfully nominated the South River to the Massachusetts Division of Ecological Restoration for Priority Restoration Project status to examine restoring the South River by removing 5 obstructions that include dams and old cranberry bog diversions that fragment the South River.

The designation enabled technical and financial support ($40,000 in 2015) to review water flow and flooding conditions under various scenarios at Chandler Pond and Veteran’s Park dam. The resulting study indicated that existing flooding occurs with or without dams at Cross Street, but would be lessened somewhat if the Veteran’s Park dam was removed. The Veteran’s Park dam creates a backwater effect that exacerbates flooding conditions upstream at Cross St.
