This category contains information on industrial uses of the Androscoggin River. The Androscoggin River was useful for industrial purposes because of the significant drop in altitude of approximately 1,200 feet from its source to its mouth. This is the largest elevation decrease of any river in Maine. The primary use of the river in the 17th and 18th centuries was for log drives and sawmills. In the 19th and mid-20th centuries, textile and paper mills flourished along the Androscoggin River. Industrial use of the river was a major contributor to pollution of the river. Edward Muskie was motivated by pollution of the Androscoggin to promote passage of the Federal Clean Water Act in 1972. Today, the primary industrial use of the river is the dams that generate electricity.
