This chapter reviews the removals of many of New England’s old industrial dams mostly constructed during the colonial era. They are low-head structures that powered America’s original iron, textile, and saw mills. But after losing their industrial purpose, they remained to degrade the ecology of the region’s rivers. As picturesque entities, however, they have become bureaucratically cumbersome to remove. The low-head dam removals reviewed here include those along the Megunticook River in Maine, the Merrimack, Charles, Taunton, Cotley, Mill, Ipswich, Concord and Shawsheen Rivers in Massachusetts, and the Piscataqua, Bellamy, and Ashuelot Rivers in New Hampshire.
