Environmental Concerns for the Merrimack

The biggest environmental concern for the Merrimack River is sewage pollution, where old cities have combined sewer systems that discharge straight to the river. In addition, runoff from streets and buildings from several cities pollutes the water. In 2018, the Merrimack was ranked as one of America's Top 10 Endangered Rivers because of the water quality impacts from polluted runoff, and from continuously damaged lands throughout the watershed. There are 847 dams throughout the Merrimack and its tributaries, some of which could be removed in the future to restore the river’s natural flow. There are six hydroelectric dams on the river.

Additional Facts


  • Several cities were built on the Merrimack during the 19th century, to capitalize on water power. The development of Concord, Manchester, and Nashua in NH, as well as Lawrence, Lowell and Haverhill in MA, severely impacted the river’s ecosystem. Sewage runoff declined the river’s health. In the 1920s, 12 millions gallons of Lowell sewage entered the river every day. However, in the 1970s, the river began improving due to activism, legislation, and restorative work.
  • “Salmon, shad and Alewives were formerly abundant here...until the dam,...and the factories at Lowell, put an end to their migrations hitherward.... Perchance, after a few thousands of years, if the fishes will be patient, and pass their summers elsewhere...nature will have levelled...the Lowell factories, and the Grass-ground River [will] run clear again.” -Henry David Thoreau, A Week on the Concord and Merrimack Rivers, 1849.

  3. Lower NH: NH border → Garvin’s Falls Dam (Bow, NH). 35 miles with 3 dams (Manchester, Hooksett and Bow). Some opportunities for boating, but can be shallow at parts. (beware for deep draft boats).
