The Neponset River is a river in eastern Massachusetts in the United States. Its headwaters are at the Neponset Reservoir in Foxborough, near Gillette Stadium. From there, the Neponset meanders generally northeast for about to its mouth at Dorchester Bay between Quincy and the Dorchester section of Boston, near the painted gas tank.

The Neponset River forms the southern boundary of the city of Boston, passing through the neighborhoods of Readville, Hyde Park, Mattapan and Dorchester, and forms the northern border of the city of Quincy. In addition, the Neponset touches the towns of Foxborough, Walpole, Sharon, Norwood, Canton, Stoughton, Westwood, Dedham, and Milton.

The Neponset River is fed by a drainage basin of approximately 130 square miles, a watershed that includes numerous aquifers, wetlands, streams, and surrounding upland areas.

History

Before Europeans arrived, the area was inhabited by Algonquian-speaking Native American tribes. The Wamsutta site (19-NF-70) is a Paleo-Indians site, which was dated to 10210 ± 60 BP). Evidence of habitation along the Neponset River also includes the Middle Archaic (ca. 5000 BC) at sites such as Green Hill near the Blue Hills.

The river's recorded history begins in 1619 when Native Americans traveled down the Neponset River to Thompson's Island, where they traded furs with English settlers.

The falling waters of the Neponset provided the energy for the country's first water-powered grist mill, gunpowder mill, paper mill and the Revere Copper Company, among others.

About of the river was placed in conduits during construction of the Foxboro Raceway and later Foxboro Stadium. During the construction of Gillette Stadium, the river was relocated to the edge of the property (adjacent to the Framingham Secondary) and daylit.

In 2021, the United States Environmental Protection Agency recommended 3.7 miles of the Lower Neponset River be added to the National Priorities List of the Superfund program, due to industrial pollution with PCBs. In March 2022, the EPA placed the segment between Mother Brook in Hyde Park to the Lower Mills on the National Priorities List.

The Bipartisan Infrastructure Law, formally known as the Infrastructure Investment and Jobs Act and enacted in 2021, allocated $3.5 billion to the Superfund Remedial Program and reinstated the Superfund chemical excise taxes that help finance hazardous waste cleanups. According to the United States Environmental Protection Agency (EPA), the additional funding expanded the agency's capacity to address contaminated sites across the country, enabling it to initiate remedial action at 49 previously unfunded locations and accelerate cleanup efforts nationwide. The investment also supported the agency's broader efforts to remediate polluted waterways and industrial sites, including locations added to the Superfund program.

Neponset River Reservation

Today the Neponset River and its watershed are increasingly being protected and opened up as a recreational destination for the benefit of local residents. Several recommendations of the 1966 Lower Neponset River Reservation Master Plan have been implemented, including the reclamation of the former Hallet Street landfill and the old Neponset Drive-In to provide the Pope John Paul II Park, which opened to the public in 2001. At Squantum Point in Quincy, phase one of Squantum Point Park, of a former U.S. Navy Airfield, was developed as waterfront parkland with assistance from National Grid plc and dedicated in the spring of 2001.

The Neponset River figures in the movie Black Mass, referencing an area south and east of the Keystone Shoreline in Dorchester, Massachusetts on the north bank, underneath the area where the Interstate 93 / Southeast Expressway / Route 1 bridge spans the river. A character in the movie makes reference to the area as "Bulger's Burial Ground", where crime boss James "Whitey" Bulger had the bodies of several of his murder victims buried. That unmarked burial ground really did exist, but in actuality was approximately one mile north of the area referenced in the film, near Tenean Beach in the Dorchester Shores Reservation.

of the Lower Neponset River Trail opened in 2003. The trail follows the former right-of-way of the Dorchester and Milton Branch Railroad, the western part of which is also used by the MBTA Mattapan Line.

The Gillette Stadium Lighthouse is the largest lighthouse-type structure in America. While the structure is located next to the Neponset River, the Gillette Stadium Lighthouse is not a government-recognized lighthouse because the Neponset River is not a federally controlled water way in Foxborough, as it is less than 2 miles wide. Gillette Stadium Lighthouse stands at 218 feet tall and 22 stories high.
