The Neponset River changes radically as it merges with the Neponset Estuary.
The Neponset River Estuary is the section of the River where freshwater and saltwater mix, creating a unique natural environment and recreational destination.
The Estuary is home to 400 acres of salt marsh that serve as a nursery for fish and shellfish, a habitat for 200+ species of birds, and a foraging spot for seals, among others.
The marshes filter stormwater runoff, capture nutrients and sediments, and help to purify the water.
Through our Coastal Resilience Program, NepRWA works with coastal communities along the Neponset Estuary to address the impacts of sea level rise and extreme weather.

Navigating the Neponset Estuary
Milton/Dorchester
As you enter the Estuary, the narrow, tree-shaded freshwater section of the Neponset River transitions into a wide-open waterway, with sprawling salt marshes and sweeping views.
Seasonal water levels in the Estuary are replaced by a twice-daily 10-foot change in the water level as tides ebb and flow.
The Neponset River is no longer limited to paddle-powered craft, as larger motor and sailboats can now access the waters of the River.
As you move further downstream, the River continues to widen and deepen as it travels two more miles to its mouth at the beginning of Dorchester Bay.
Turning downstream from Milton Landing, paddlers will be surrounded by the marshes of the Neponset River Reservation for 1.2 miles until reaching the Granite Avenue Drawbridge.
Neponset River Reservation
Moving further down the River into the Estuary, Pope John Paul II Park comes up on the left.
The State converted the former landfills into parkland, which now serves as the active recreation centerpiece for the Neponset Greenway Trail.
The area that makes up Pope John Paul II Park used to be the Hallet Street Dump and Neponset Drive-in movie theater.
Before these areas were turned into the park, the old landfills were first sealed off with a waterproof cap to prevent rainwater from soaking into the old landfill and then leaching into the river.
Davenport Creek emerges into the Neponset in the middle of Pope John Paul II Park.
Along the way, the first major tidal creek entering on the right is Gulliver’s Creek, which drains part of Milton and is another important smelt spawning area
Quincy
On the Quincy side of the river to the right, is the Quincy RiverWalk, which connects with the Neponset Greenway on the Boston side of the River.
The first creek on the Quincy side is Sagamore Creek, which emerges from the buildings and vast parking lots of the State Street South development. Further downstream on the Quincy side is Billings Creek, which is surrounded by salt marsh.
At the landmark painted gas tank, the River is flanked by Tenean Beach in Dorchester on the left and Squantum Point Beach in Quincy on the right.
Paddle the Estuary!
A great way to experience the Neponset Estuary is to paddle it. We recommend paddling at mid to high tide, launching from Milton Landing or DCR Neponset Park in Dorchester.
