accessed October 3, 2011 is a tributary of the Merrimack River in Massachusetts and New Hampshire in the United States. It is formed in eastern Worcester County, Massachusetts, at the confluence of the North Nashua River and South Nashua River, and flows generally north-northeast past Groton to join the Merrimack at Nashua, New Hampshire. The Nashua River watershed occupies a major portion of north-central Massachusetts and a much smaller portion of southern New Hampshire.

The North Nashua River rises west of Fitchburg and Westminster. It flows about generally southeast past Fitchburg, and joins the South Nashua River, shown on USGS topographic maps as the main stem of the Nashua River, about below its issuance from the Wachusett Reservoir.

History

The river's name derives from an Algonkian word meaning "beautiful river with a pebbly bottom."

The Nashua River was heavily used for industry during the colonial period and the early years of the United States. During the late 18th century and early 19th century, the heavy concentration of paper mills and the use of dyes near Fitchburg resulted in pollution that notoriously turned the river various colors downstream from the factories.

In the mid-1960s, Marion Stoddart started a campaign to restore the Nashua River and its tributaries. She built coalitions with labor leaders and business leaders, in particular the paper companies who were the worst polluters of the river. With federal help, eight treatment plants were built or upgraded along the river. A broad conservation buffer was created along about half the river and its two main tributaries. By the early-1990s, most of the industry was still located along the river, but many parts of the river were once again safe for swimming. Her work is the subject of a 30-minute documentary movie titled ''Marion Stoddart: Work of 1000''.

Recovery has sparked recreational use of the river at places like Mine Falls Park in Nashua.

The largely volunteer Nashua River Watershed Association, based in Groton, Massachusetts, oversees the condition of the river.

In 2013, Public Law 116–9 designated of the Nashua River as a National Wild and Scenic River. The legislation was sponsored by Rep. Niki Tsongas (D, MA-3), supported by the Nashua River Watershed Association and The Wilderness Society.

Watershed

From its impoundment at the Wachusett Reservoir in Clinton, Massachusetts, the South Nashua River flows north and joins the North Nashua River in Lancaster. The North Nashua River flows southeast from Fitchburg and Leominster to Lancaster. The Nashua River flows northward from Lancaster, meandering its way through the north-central Massachusetts towns of Harvard, Groton, Dunstable, and Pepperell, before eventually emptying into the Merrimack River at Nashua, New Hampshire. The Nashua River watershed has a total drainage area of approximately , with of the watershed occurring in Massachusetts and in New Hampshire. The Nashua River flows for approximately , with approximately 46 of those miles (74 km) flowing through Massachusetts. The Squannacook, Nissitissit, Stillwater, Quinapoxet, North Nashua, and South Nashua rivers feed it. The watershed encompasses all or part of 31 communities, 7 in southern New Hampshire and 24 in central Massachusetts. The watershed's largest water body is the Wachusett Reservoir, which provides drinking water to two-thirds of the Commonwealth's population.
