Norwich Water Power Company, Canal Drain Gate, West bank of Shetucket River opposite Twelfth Street, Greenville section, Norwich, New London County, CT

Significance: The drain gate is significant as an integral part of a project that rebuilt the dam and headgates of the Norwich Water Power Company's canal. The project reduced the length of the canal and improved the flow of water, thereby better meeting the needs of the numerous manufacturers who had located their factories along the Company's canal. Taken together, the Greeneville mills represented the largest concentration of industry in Norwich throughout the 19th century, and the water and waterpower provided by the dam and canal were vital to their operation.
