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.

NRWA Water Monitoring Program

This year (2023) marks the 31st season that dedicated volunteers have monitored water quality and reported conditions and observations at over 30 sites throughout the Nashua River watershed. The Water Monitoring Program builds community awareness of water issues, helps identify and restore problem sites, promotes advocacy for our watershed, and increases the volume of information available on our waters. We use the monitoring results to create a River Report Card that is shared with volunteers, the public, and Massachusetts and New Hampshire state agencies each month. View historic water quality data. For more information on what we monitor, and why, see our Volunteer Water Monitoring Manual. Monitoring for the 2022 season is supported in part by grants from the Greater Lowell Community Foundation and the Fieldstone Foundation.

For a peek at what it's like to be a volunteer monitor, view videos created by Dawn McCall and Mike Labbe, NRWA Water Monitors from Shirley: Water Sampling and In the Lab.

Protecting Our Rivers and Streams

The quality of the water in our rivers and streams is a reflection of the health of our entire watershed ecosystem. The impact of any land use practice on the quality or quantity of water can be substantial. Clean rivers are a must for healthy, sustainable aquatic life and for pleasurable, safe recreation.

Willard Brook in Townsend, MA – Photo by Kim KingOne of the primary threats to water quality in the Nashua River watershed are the pollutants that make it to streams, rivers, lakes, and ponds in stormwater runoff. Rain water and melting snow wash pollutants such as nutrients (primarily nitrogen and phosphorus), oil, grease, sediment, bacteria and heavy metals into nearby waterways. The sources of the pollutants include lawns and agricultural fields, roadways and parking lots, uncollected pet waste, and erosion from development.

The NRWA works to maintain and improve the water quality in our rivers through our Water Monitoring Program where dedicated volunteers are our eyes on the rivers and streams throughout the watershed, and help to gather water quality data, monthly from April through October. This program has been in existence for two decades, creating a historic record of the health of our local waterways that helps us to better assess current conditions. The NRWA Water Monitoring Program’s Quality Assurance Project Plan has been approved by the U.S. Environmental Protection Agency, Massachusetts Department of Environmental Protection, and New Hampshire Department of Environmental Services, and ensures that the data collected is accepted for assessment reports by each of these agencies.

The legacy of aging infrastructure in urban areas is also something we work to improve. For example, NRWA works on site-specific projects including tracking sources of bacteria in the City of Fitchburg. NRWA has educated businesses about the importance of closing illicit floor drains in Lancaster, and the annual Monoosnoc Brook Clean-up in Leominster celebrated its 25th year in 2011. More on NRWA water quality projects.
