The Saco River defines the industrial and geographic character of this region of York County, powering several historic mill sites that survived into the early 21st century. The map illustrates a landscape where early water-powered industry at Bar Mills, Salmon Falls, and Clarks Mills evolved into a modern hydroelectric network. Significant infrastructure such as the Skelton Dam, Union Falls Dam, and the Bar Mills Dam has transformed the river, creating the Saco River Reservoir and providing a foundation for local development.
