About the Watershed Association

The Souhegan Watershed Association (SWA) located in Merrimack, NH began in 1995 with the mission of speaking for the river without regard for town or state boundaries. The SWA is organized by people who live along the Souhegan River in southern New Hampshire. They work to improve and maintain the environmental quality and the cultural, economic and scenic diversity of the Souhegan River and its watershed. The goals of the SWA are:
  • To protect and improve the water quality and quantity of the Souhegan River system.
  • To educate the public about environmental issues pertinent to the health of the Souhegan River Wateshed.
  • To support the continuing utilization of the Souhegan River for multiple uses.
The SWA has been active in sponsoring canoe trips along the river, in water quality monitoring, in sponsoring river cleanups, in obtaining conservation- protected land and creating trails along the river. SWA has published information about the river through a Green Guide and participated in a comprehensive river management plan. SWA maintains connections with other local watershed associations and works cooperatively with them.
The Souhegan Watershed includes parts of the towns of Amherst, Bedford, Greenfield, Greenville, Lyndeborough, Mason, Merrimack, Milford, Mont Vernon, New Ipswich, Temple, and Wilton New Hampshire, and also Ashby and Ashburnham, Massachussetts. The river is about 35 miles long and it is used for water supplies, hydropower, and recreation. There are also 28 threatened or endangered species sharing the watershed with 35,000 people.
