THE STORY BEHIND THE PHOTOGRAPHS

People, places, and change.

Selling waterpower in Greeneville

The Norwich Water Power Company incorporated in 1828 and developed a dam and canal the following year. Its enterprise helped establish Greeneville as an industrial district along the Shetucket River. Rather than operating only one factory, the company supplied a setting in which multiple manufacturers could use waterpower. The canal, mill sites, river, and transportation routes formed a connected landscape. By the middle of the nineteenth century, textile and other industrial activities made that arrangement part of Norwich’s wider manufacturing economy. The district’s later history depended on repeated investment in the underlying waterworks. [2]

Rebuilding the river works

The system changed substantially in 1882 under engineer Hiram Cook. New headgates and major dam work reorganized the control of water entering the canal. Flood damage in 1886 prompted further repairs, and the timber portion of the dam was rebuilt again in 1915. The surviving structure therefore contained work from different campaigns rather than a single original construction. Federal photographs made during work in December 1995 exposed parts of that layered fabric. Their captions identify masonry and timber features that are difficult to understand from an ordinary view across the river. [2] [5] [6]

Gates, spillways, and electrical generation

The smaller waterworks are essential to the story. Six arched headgate openings controlled admission to the canal; spillway and drain structures handled water at other points in the system. The canal supplied a series of mill sites, while later electrical generation changed the use of the available power. A municipal hydroelectric installation opened in 1926, followed by another plant in 1966. These developments show continuity in the exploitation of the river even as machinery and customers changed. The photographs join the impressive dam to the less conspicuous controls that made the larger arrangement workable. [2] [8] [11] [14]

An engineering landscape recorded in the 1990s

Wayne Fleming photographed the waterworks in June 1994 and returned for additional dam views in December 1995. The resulting records document broad settings and individual components, including the canal, dam face, headgate mechanisms, spillway bridge, and drain-gate shelter. They preserve evidence of nineteenth- and twentieth-century construction during a period of new work associated with the river. The images are dated records of the system as it then existed. Read alongside the historical reports, they help visitors trace how a neighborhood’s industrial history can remain visible in waterways and structures after many original manufacturing uses have disappeared.
