North Canal

Why it's listed
Running 5,300 feet parallel to the Merrimack River, the North Canal supplied water power to the mills of Lawrence, Massachusetts. Work began in August 1845, and the canal was finished in August 1848. It is 100 feet wide at its head and 60 feet at its end, with granite walls and a puddled bottom of sand, clay and gravel. A Greek Revival wood-frame gatehouse controls 24 headgates at the western end. The Essex Company, which had earlier founded Lowell, chose the site for the new city of Lawrence because the terrain suited a canal. Charles S. Storrow was principal engineer, assisted by James B. Francis, with Charles Bigelow as construction engineer. The design improved on the Lowell canals, and the canal has needed little more than minimal maintenance since 1848. It powered nearly all the city's mills until the 1880s, when steam engines were adopted, and the canal also shaped the city's grid layout.
Significance in brief: The canal was central to founding Lawrence and to its growth as a leading textile manufacturing center before World War I. Its design reflected the best civil engineering of its time and improved on the earlier Lowell canals. It has needed only minimal maintenance since 1848.
