Food Advisory: Fish

Is the freshwater fish that you recently caught safe to eat? Fish can absorb pollution from the water, so before eating any local fish, make sure to check for advisories or warnings. If you fish in freshwater and eat your catch, it’s important to keep up to date on the Freshwater Fish Consumption Advisory List, […]

Small Dam Removal Program

The Watershed Association has embarked on a program to remove small dams from streams around the watershed, to re-connect and restore the function and health of our river system. By removing small dams (over 115 exist in our watershed!), we: Restore opportunities for fish and other aquatic wildlife to travel longer stream lengths; to pass […]

Pollutants Make Fish from Some Local Waters Unsafe to Eat

With the warmer weather returning, fish migrating, and fishermen returning to the water, we remind all to check waterbodies for related fish consumption advisories before eating your catch. Please spread the word – and this link: For Neponset waterbodies, click here.

Herring Documentary in the Works

Here at the Neponset Watershed Association, we often mention river herring – in particular, the opportunity to restore these fish species (alewife and blueback herring) and others to more of the Neponset River. Our focus has been to work toward removing the obstacles to fish passage between the estuary and the freshwater portions of the […]

Pollution Responsibility

Before we can restore fish passage past the Baker and the Tileston & Hollingsworth Dams, the PCB-contaminated sediments that have accumulated behind each dam must be cleaned up.

Recreational Improvements

Dam removal would greatly expand fishing opportunities. Boating which is currently blocked by the dams would be safer and considerably more enjoyable, and the safety of those recreating along the banks of the river would be enhanced. Removing the dams also would change the appearance of the river as seen from the perspective of those […]

Industrial Uses & Hydropower

Neither the Baker Dam nor the Tileston & Hollingsworth Dam is used to generate hydropower, nor are they likely to be used to do so in the future. The characteristics of these sites are not conducive to generating power in this day and age.


Modifying or removing both the Baker and the Tileston & Hollingsworth Dams would open up passage for migratory fish to swim between the fresh water of the Neponset River and its tributaries, the brackish water of the Neponset Estuary, and the salt water of Boston Harbor.

Community Participation

Representatives of neighborhood groups and civic associations have been brought together to consider alternatives for restoring the Lower Neponset River.

Public Health

The health of the Lower Neponset River is complicated by the contamination of its sediments with PCBs (polychlorinated biphenyls), in the area downstream of Mother Brook, in Hyde Park, Mattapan, Dorchester and Milton.

Historic Resources

The Neponset River has a long and rich industrial history, the remainders of which we continue to experience today.

Flood Prevention

The Baker Dam at Lower Mills causes increased flooding, and the T&H Dam upstream serves no meaningful flood control purpose. Removing these two dams would reduce flooding on the Lower Neponset River.

Aesthetics of River Restoration

  Over the last 30 years, pollution in the Neponset River has been reduced, the buildings along its shores have been converted to residential and commercial rather than industrial use, and its banks have been improved for recreation. All of these changes have dramatically increased the river’s importance as an aesthetically pleasing backdrop that people […]

Controlling Exotic, Invasive Species

Exotic, invasive species bring turmoil to a natural system; they can out compete native species and reproduce vastly, taking over a significant swathe of the ecosystem in a short time, changing the structure and composition of wildlife habitat, reducing diversity of species, and even changing the availability and make-up of water resources. Over the years, […]

Salt Marsh Restoration

Land use along the Neponset River has had a lengthy and colorful history—from industrial to residential land use, commerce to quarrying. Many of these activities significantly have affected the health of the Neponset Estuary salt marshes. In fact, Boston Harbor Watershed salt marshes have dwindled since the arrival of European colonists. Much of Boston’s marshes […]

2010 Project Update

November 2010 Purple Loosestrife Biocontrol Project Update In 2010, Beetle Ranching volunteers from around the Neponset River Watershed and beyond carefully raised Galerucella calmariensis & G. pusilla beetles for this project to reduce exotic, invasive Purple loosestrife in the Fowl Meadow wetlands, Brookwood Farm, and at adjacent wetland areas. Over the years, these beetles and […]

Purple Loosestrife Biological Control Project

October 2011 Project Update In 2011, we raised Purple loosestrife biological control (“biocontrol”) beetles (Galerucella calmariensis and G. pusilla) to treat Purple loosestrife in the northern Fowl Meadow wetlands and in nearby Brookwood Farm, in quantities guided by recommendations from project advisor the Massachusetts Department of Ecological Restoration (DER). Our goal has been to produce […]
