Environmental Concerns for the Merrimack


As of 2020, the biggest environmental concern for the Merrimack River is polluted runoff. Due to the various cities located on the Merrimack, the river is threatened by further infrastructure and roads. The river is ranked one of the most threatened because of the continuously damaged lands throughout its watershed. Additionally, there are 847 dams throughout the Merrimack and its tributaries, some of which will possibly be removed in the future to restore the river’s sustainability. There are six hydroelectric dams on the river. To learn more about environmental challenges currently facing the Merrimack River, click here.




Additional Facts


History:

  • Several cities were built on the Merrimack during the 19th century, to capitalize on water power. In New Hampshire, Concord, Manchester, and Nashua were all built on the Merrimack. In Massachusetts, Lawrence, Lowell, and Haverhill were built. The creation of these cities severely impacted the river’s ecosystem. Run off, sewage, and wastes 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 action.
  • “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).
