The Locks and Canals District encompasses all of the canals in the city of Lowell, their associated locks, and the mills that were powered by the canals. This canal system led to the supremacy of Lowell as the cotton textile manufacturing center of the United States, and contributed to the evolution of the first major American industrial city. The District contains virtually unaltered waterways, mills and machinery. -- National Historic Landmark statement of significance, December 22, 1977
