West Hill is the westernmost hill in Mendon. Nearly all of its western slope is in Uxbridge, and this is where the dam is located. The town of Northbridge is immediately to the north of this site and includes some of the reservoir trapped behind the West Hill Dam. West Hill and West Hill Dam are in the northeastern part of Uxbridge township. The actual summit of West Hill is in the adjacent town of Mendon. The federal reserve contains 567 acres in the townships of Uxbridge, Northbridge, and Upton, Massachusetts. The New England town or township is a unique municipality unit unlike those of any other geographic region of the United States.
Historic context and location

Early water powered mills, including some downstream on the West River, and Blackstone River, helped jumpstart America's Industrial Revolution in this river valley region. The Blackstone Valley is a New Englandupland region with elevations from approximately two hundred feet to over six hundred feet above sea level. West Hill Dam is located about thirty-four miles west-southwest of Boston, and about fifteen miles southeast of Worcester.
