A watershed is the area of land that drains into a body of water, like a river, pond, harbor or lake.

What is the Neponset River Watershed?

  • It includes roughly 130 square miles of land southwest of Boston. All of this land drains into the Neponset River, and ultimately into Boston Harbor.
  • The Neponset River is 30 miles long. It starts in Foxborough, near Gillette Stadium, and ends in Dorchester/Quincy, near the “Rainbow Swash” gas tank by I-93.
  • Over 330,000 people live in the Neponset Watershed.
  • More than 120,000 get some or all of their drinking water from within the boundaries.
  • It’s a destination for hikers, cyclists, fishermen, and paddlers.
  • Contains invaluable habitat for our native fish and wildlife.
  • Has a history that includes 10,000 years of human habitation and over 375 years of industrialization.

Cities and towns include Boston (Dorchester, Hyde Park, Mattapan), Canton, Dedham, Dover, Foxborough, Medfield, Milton, Norwood, Quincy, Randolph, Sharon, Stoughton, Walpole, and Westwood.
