Whitney Pond Dam Removal & River Restoration Project: Ashburnham

Under a grant from the MA Division of Ecological Restoration (DER), the NRWA is helping to lead outreach and information efforts in Ashburnham in regards to the town's decision to remove the Whitney Pond Dam. The NRWA views dam removal on a case-by-case basis. Each dam, community, and waterway has its own unique set of circumstances that need to be fully understood in the decision-making process. In the end, the decision to repair or remove must be made by the dam owner, in this instance the Town of Ashburnham. Learn more about this project including information about the Whitney Pond Dam, videos of community meetings, plans and permitting documents, and benefits of removal and restoration.

Dam Removals Across New England

Across New England, aging and unsafe dam infrastructure has led to an increase in dam removals. These dam removals can provide significant public safety and ecological benefits, from a reduced risk of flooding to restored river connectivity. Supported by the MA Division of Ecological Restoration, the Nashua River Watershed Association offered educational talks about dam removals in Massachusetts, covering a general overview of why and how unsafe dams are removed, and what changes you might expect to see in your community as a result. Presentations were made possible in part by a grant from the MA Division of Ecological Restoration.

Using Nature to Adapt to Climate Change in the Nashua River Watershed

The NRWA is working with the communities of Ashburnham, Fitchburg, Groton, Leominster, and Pepperell to understand local climate change issues and ways that we can use Nature-based Solutions to address those issues. Citizen input is key to the process as NRWA, town leadership, and consultants work to identify specific sites and solutions to help each  community become more climate resilient. The concepts developed in these five communities will then be applied to create a Nashua River Watershed Nature-based Solutions Plan with tools accessible to all of our watershed communities. This project is funded by a Massachusetts Municipal Vulnerability Preparedness (MVP) grant. Learn more about this project and Nature-based Solutions.

Nashua River Watershed Association Statement on MassWildlife’s Proposed Oak Woodlands Restoration at Squannacook River Wildlife Management Area

The MA Department of Fisheries and Wildlife (MassWildlife) has proposed an Oak Woodlands Restoration project on 215 acres at the Squannacook River Wildlife Management Area (SRWMA), which will result in altering the current forested landscape to an open woodland. The project would require significant clearing of the existing forest, periodic fire management, and herbicide applications.  For a more detailed description of the goals of the proposed project and restoration activities, please see: mass.gov/info-details/oak-woodland-restoration-at-squannacook-river-wma

The Nashua River Watershed Association (NRWA) has been closely keeping track of this proposed project and wishes to share the following significant attributes of the SRWMA project site, which MassWildlife has indicated would be Phase 1* of a multi-phase undertaking:

  • Abuts ~2 miles of the federally-designated Squannacook Wild & Scenic River, which is also a state-designated Coldwater Fisheries Resource; 
  • Is within the state-designated Squannassit Area of Critical Environmental Concern; and 
  • Is a Natural Heritage and Endangered Species Priority Habitat Area.
  • Meets MA DEP state-designated Outstanding Resource Water Massachusetts Surface Water Quality Standards [314  CMR 4.04(3)

  • Is included in the Squannacook-Nissitissit Rivers Sanctuary Act (MGL, Part I, Title XIX, Chapter 123A, Section 17)

  • Is a National Oceanic and Atmospheric Administration (NOAA) Fisheries “Essential Fish Habitat”

  • Is a MA DFW Wildlife Management Area Reference Stream

  • US Geological Survey (USGS) gage on the Squannacook River was used as a least impacted site to set flow policy for the state’s Water Management Act. The river is also used as a “clean water” least impacted site by MA DEP’s SMART monitoring program. Water quality information from this site was used in the development of statewide Water Quality Standards including nutrients and pollutant loading analysis.

  • ~50 acres of Shirley Zone 1 Municipal Wellhead Protection Area (a 1,000 foot zone extending from wellhead)  

  • Subject property partially overlays a medium yield aquifer ½ mile upstream from the W. Groton Water Supply District public wellheads.

This site has long been recognized as an area worthy of the highest-level protection and preservation for its existing outstandingly remarkable environmental resource values. Therefore, proposed alteration of the site should be subject to particularly rigorous analysis.

In February of 2022 the NRWA requested that MassWildlife consider at least a three-year moratorium on advancing the proposed project while MassWildlife, NRWA, and other partners: 

  • Identify alternate sites that meet MassWildlife’s state-wide goals for Oak Woodland Habitat;
  • Undertake additional studies on SRWMA; and 
  • Assess the impact of the scale of the proposed project. 

Through dialogue with MassWildlife, the NRWA understands that MassWildlife cannot agree to a moratorium.  MassWildlife has communicated a commitment to transparency and to proceeding on a timeline with opportunities for site walks and public engagement. 

In addition, public comment periods which are required as part of local and state permitting would precede any actual site work by MassWildlife.  Opportunities for comments would occur at both Shirley and Townsend Conservation Commission meetings, and potentially be associated with an Environmental Notification Form (ENF) and Massachusetts Environmental Policy Act (MEPA) review.  After reviewing forthcoming documents, the NRWA will offer detailed comments during the public comment periods as they arise.

* The NRWA notes that potential future Phases of the proposed project have not yet been described, but that the entire Squannacook River Wildlife Management Area encompasses a total of more than 1,300 acres.

Greenway Trails: Conservation and Recreation

Recreational opportunities and public access to our rivers are benefits of improved water quality and riverside greenway protection. The creation of riverside parks, hiking trails, and rail trails is a part of NRWA’s work to promote and preserve greenway in our watershed.

Rail Trails

Since 2000, the NRWA has been continuously involved in the Squannacook River Rail Trail (SRRT) project, the goal of which is to build a rail trail along the MBTA owned, but discontinued, Greenville Branch of the Boston & Maine Railroad that runs near the Squannacook River. Work on the SRRT is being forwarded by the non-profit organization, Squannacook Greenways.

A quiet woodland trail along the Squannacook River in Townsend, MA - Photo by Kim KingThe SRRT, as proposed, is a 3.7 mile rail trail that would stretch from West Groton to Townsend center, passing by the North Middlesex Regional High School, two shopping centers, historical districts, protected open space, and other key resources; furthermore, it would allow for alternative transportation parallel to, but off of, the heavily trafficked Route 119. There is strong community support for this project and abutter concerns have been considered and addressed.

The NRWA recognizes the unique opportunity such a trail would have to highlight and complement the Squannacook River Greenway, which includes associated state conservation lands. A level and easy-to-navigate linear rail trail is an “entrance pass” to the outdoors for a great many people who would otherwise choose not to venture into the “wilderness”.

The NRWA also played a role in the creation of the Nashua River Rail Trail that runs 11 miles from Ayer, Massachusetts to Nashua, New Hampshire. The paved trail, which officially opened in 2002, is built on the old Hollis Branch of the Boston & Maine Railroad. The Hollis Branch was purchased by the Massachusetts Department of Conservation and Recreation (formerly the Department of Environmental Management) in 1987, and the path was built by Mass Highway. The paved trail is open for walking, biking, and cross-country skiing, and includes a seven-mile stretch with an added gravel path for equestrians.

Riverside Parks

Riverside parks in the watershed’s urban areas have been invaluable in allowing city residents and businesses to revitalize their city centers around the natural beauty of their riverfront. Both Fitchburg, Massachusetts and Nashua, New Hampshire have included the Nashua River as a key component in their redevelopment plans. View the North Nashua River Master Plan for Fitchburg and the Nashua, NH Master Plan.

Through the efforts of the NRWA, the City, the Fitchburg Greenway Committee, and numerous other entities including the North County Land Trust, The Trustees of Reservations, and the Commonwealth, Fitchburg has been successful in protecting sections of its Greenway and has created three riverside parks for the enjoyment of its citizens. The Steamline Trail Park reminds hikers of the city’s historic link to the river as it begins at the old Central Steam Plant and follows alongside the pipes that once powered Fitchburg mills. Riverfront Park offers a large open space for festivals and community events. Fitchburg’s newest park, Gateway Park, has a trail, recreational space, picnic areas, and community gardens. For more about park and trails in Fitchburg. 

In Nashua, New Hampshire, the Nashua River runs through the center of the old downtown area which is experiencing a strong revival. Mine Falls Park is a 325-acre park bordered by the Nashua River and the Mill Pond and canal, once used for generating power in Nashua’s mills. The park has extensive trails and access to the water for boating and fishing. At the center of the downtown area, the City has created a Riverwalk that extends for stretches on both sides of the river giving visitors views of the river and historic mills, as well as providing pedestrian access to downtown shops, restaurants, and the public library. For more about parks and trails in Nashua.

Citizen Action: Local Greenway Committees and Friends Groups

Protecting and managing the watershed’s riverfront lands continues to be a key aspect of the NRWA’s overall watershed management plan. Volunteers are helping the Greenway grow through community outreach, landowner assistance, and improving the management of Greenway lands. Local land trusts in Massachusetts and New Hampshire partner with the NRWA to protect riverfront greenway, as does the Nashua, Squannacook, and Nissitissit Rivers Wild and Scenic Stewardship Council. There are also volunteers who directly assist the NRWA, and, in some communities, have formed local groups with which the NRWA works closely. Several Greenway committees, some established by local governments and some by citizen volunteers, work to complete the protection of the Nashua River and its tributaries, including:

Fitchburg Greenway Committee in Fitchburg, MA

Plans for the Gateway Park in Fitchburg, MAThe NRWA has been a key participant in the Fitchburg Greenway Committee (FGC) from its inception. The FGC evolved directly from the Fitchburg Stream Team, initiated by the NRWA, which was active in the late 1990’s and early 2000’s, and includes many of the same core members. The Stream Team produced two shoreline surveys inventorying existing conditions in and alongside of the entire seven mile stretch of the river throughout the City. A report addressed most pressing issues and the most likely opportunities for improvement, including the cleanup of a massive riverside illegal dump along West Street, which the Team successfully undertook. That site is now Fitchburg’s new Gateway Park and loop trail, a collaborative project that involved many partners including Fitchburg Greenway Committee, the NRWA, the City of Fitchburg, the MA Executive Office of Energy & Environmental Affairs, The Trustees of Reservations, North County Land Trust, and WDC Construction, Inc. Today’s FGC is active in several areas including riverfront open space protection; Riverfront Park modifications resulting in greater access to the river, as well as improved in-stream habitat and flow conditions; updating of the city’s wetland ordinance; and numerous educational events. The Trustees of Reservations named the Fitchburg Greenway Committee as its Conservationists of the Year in 2010.

Groton Greenway Committee in Groton, MA

The Groton Greenway Committee was established in 1989 at the request of the Nashua River Watershed Association. The Committee sponsors nature walks, canoe trips, river cleanups, water chestnut pulls, and also a semi-annual river festival. Its official charge is to:

  • protect river and stream frontage in Groton, particularly along the Nashua and Squannacook Rivers;
  • complete a buffer along these waterways to prevent pollution and provide flood protection, recreation, wildlife habitat, trail connectors, and scenic beauty;
  • educate townspeople to the environmental and financial importance of protecting riverfront lands;
  • seek gifts of land or easements along the riverways; and,
  • seek the opportunity to purchase frontage.

View the Groton Greenway Committee’s “Completing the Vision” slideshow. 

Shirley Greenway Committee in Shirley, MA

The Shirley Greenway Committee if officially charged to:

  • Conserve and enhance waterfront land to protect and preserve Shirley’s river, stream, and pond resources, and coordinate with other greenway efforts in the Nashua River Watershed

  • Work with Town Boards, Commissions, and Departments in the implementation of the Town of Shirley’s Open Space and Recreation Plan 

  • Work with the Board of Selectman, Conservation Commission, and landowners for the acquisition of land for conservation and recreation purposes, and other purposes protected by Article 97 of the Massachusetts constitution

Lancaster Friends of the Nashua River in Lancaster, MA 

Lancaster Friends of the Nashua River was a chapter of the Nashua River Watershed Association formed in 2011. The Friends group defined its mission and goals for work in Lancaster -- raising consciousness among Lancaster residents and promoting environmental education -- deliberately designing its activities to dovetail with and support the mission and goals of the broader NRWA. The group raised funds and implemented projects to improve trails at the Cook Conservation Area and held annual river festivals for a number of years.

The project responded to the concerns of local businesses and City officials who noted the neglect and deterioration of the brook which had become littered with garbage. Through cleanups, site work, education and other events, the MBGP has been successful in restoring the beauty of the brook, and walking trails and small park areas have been established. MBGP has provided hundreds of free programs to school children in Leominster, has installed rain gardens and outdoor classroom spaces at Fall Brook Elementary School, and conducted an Annual Cleanup of the brook for over 25 years.

Protecting the Nashua River Greenway

The Nashua River Watershed Association acts as advocate and advisor for the establishment of the Nashua River Greenway. Conservation of the river’s edge is a priority, as expressed in our founding vision of “sparkling blue water with a ribbon of green alongside it.” NRWA encourages a permanently protected open space corridor along both banks of the Nashua River, its main tributaries, and its smaller streams as well. In rural areas, this Greenway can be a natural buffer (ideally 300 feet wide) to filter pollutants, prevent soil erosion, provide floodways, protect wildlife habitat, and offer outdoor recreation, like riverfront trails. In urban areas, the Greenway can conserve water supplies, increase the value of land adjacent to the Greenway, stimulate downtown revitalization, and provide riverside parks for recreation and public access to the river.

The Association has chosen not to acquire land itself, and has passed a Conservation Restriction Policy. We do work closely with local Greenway committees, landowners, communities, conservation groups, and public agencies to help them protect and improve riverfront lands.

In its first three decades, the Greenway expanded from 2 miles of protected riverfront to 84 miles. In the past decade, that figure has more than doubled to over 174 miles of shoreline that are dedicated to open space. The environmental and economic benefits of the Greenway are being realized. While much has already been accomplished, there is much to be done. View Nashua River greenway map and greenway statistics.

To conserve land along the Nashua River and its tributaries, the NRWA promotes the purchase or donation of riverfront lands, conservation agreements with private landowners, and land use controls (zoning, wetlands protection, and low impact development). In addition to promoting Greenway protection, the Association encourages appropriate uses and improvements for lands along the river, such as agriculture, forestry and wildlife management; canoe launches and picnic areas; hiking trails, walkways, and bikeways; and parks and riverfront design in urban areas. To encourage these improvements, the NRWA offers assistance on design projects and management plans for Greenway lands.

A considerable public and private investment has made clean-up of the Nashua River a reality. The Greenway protects this investment while it enhances the use and enjoyment of the river. As water quality continues to improve and as more riverfront conservation lands are connected, the Greenway becomes an increasingly important asset to our communities.

Wild & Scenic Rivers: Protecting Outstanding Waterways

River segments included in Nashua River Wild & Scenic River Study ActAn effort is underway to explore whether sections of the Nashua, Squannacook, and Nissitissit Rivers could be designated as Partnership Wild and Scenic Rivers.

The Nashua River Watershed Association brought the opportunity to explore such a designation to the attention of the communities through which these rivers flow: the Boards of Selectmen in Ayer, Dunstable, Groton, Harvard, Lancaster, Shirley, Pepperell, and Townsend all endorsed pursuing a Study.

Congresswoman Niki Tsongas filed the bill H.R. 5319, the "Nashua River Wild and Scenic River Study Act".  To announce the introduction of the legislation, the Congresswoman held a press event at NRWA’s RiverResourceCenter in Groton. 

NRWA's Executive Director, Elizabeth Ainsley Campbell, submitted testimony in favor of HR 5319 and spoke at a legislative hearing held at the Longworth House Office Building in Washington, D.C. by the Subcommittee on National Parks, Forest and Public Lands.

The National Park Service conducted a Reconnaissance Survey that confirmed "that the Nashua River and its tributaries have all the ingredients for a successful Wild and Scenic River Study: highly significant natural, cultural and recreational resources; capable and committed local partners; and local communities with a demonstrated track record of support for conservation of the River," said Jamie Fosburgh, the New England Team Leader for Wild and Scenic Rivers.
