The Nashua River, {{convert|37.5|mi}} long,U.S. Geological Survey. National Hydrography Dataset high-resolution flowline data. [http://viewer.nationalmap.gov/viewer/ The National Map], 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 {{convert|30|mi}} generally southeast past Fitchburg, and joins the South Nashua River,{{cite web| url=https://www.rivers.gov/rivers/nashua.php| title=Nashua River, Massachusetts & New Hampshire| publisher=National Wild and Scenic Rivers System| access-date=December 29, 2020}} shown on USGS topographic maps as the main stem of the Nashua River,{{Cite gnis|617989|Nashua River}} about {{convert|5|mi|0}} below its issuance from the Wachusett Reservoir.

History

The river's name derives from an Algonkian word meaning "beautiful river with a pebbly bottom."{{Cite book|url=https://books.google.com/books?id=6YMbAQAAMAAJ&q=nashua++|title=The Native North American Almanac|date=April 24, 2001|publisher=Gale Research, Incorporated|isbn=9780787616557|via=Google Books}}{{Cite book|url=https://books.google.com/books?id=xCHQC6Mk3tIC&q=+nashua|title=Signatures|first1=Roger C.|last1=Farr|first2=Dorothy S.|last2=Strickland|first3=Richard F.|last3=Abrahamson|first4=Harcourt Brace &|last4=Company|date=April 24, 1999|publisher=Harcourt Brace|isbn=9780153101243|via=Google Books}}

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.{{Cite web| url=https://www.der.org/work-of-1000/| title=Marion Stoddart: The Work of 1000| website=Documentary Educational Resources| access-date=April 24, 2020}}

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.{{Cite web|url=http://www.nashuariverwatershed.org/|title=Nashua River Watershed Association - Home|website=www.nashuariverwatershed.org}}

In 2013, Public Law 116–9{{USPL|116|9}} designated {{Cvt|27|mi|km}} 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{{cite web|date=June 6, 2013|title=Tsongas testifies in favor of bill to designate Nashua River as Wild and Scenic|url=http://tsongas.house.gov/press-releases/tsongas-testifies-in-favor-of-bill-to-designate-nashua-river-as-wild-scenic/|accessdate=June 23, 2014|publisher=House Office of Rep.

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 {{convert|538|sqmi}}, with {{convert|454|sqmi}} of the watershed occurring in Massachusetts and {{convert|74|sqmi}} in New Hampshire. The Nashua River flows for approximately {{convert|56|mi}}, 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.{{cite web| url=http://www.mass.gov/envir/water/nashua/nashua.htm| title=Nashua River Watershed| access-date=2007-01-03}}
