Acton is a suburban town in Middlesex County, Massachusetts, United States about twenty-one miles west-northwest of Boston along Route 2 west of Concord and about ten miles (18 km) southwest of Lowell. It is bordered by Westford and Littleton to the north, Concord and Carlisle to the east, Stow and Maynard to the south, and Boxborough to the west. Acton became an incorporated town in 1735. The town employs the Open Town Meeting form of government with a Town Manager and an elected, 5-member Board of Selectmen. Acton was named the 16th Best Place To Live among small towns in the country by Money Magazine in 2009 and in 2011. The local high school, Acton-Boxborough Regional High School, was named a Blue Ribbon School by the U.S. Department of Education in 2009. Acton has two primary stream systems: the Nashoba Brook system including the incoming streams Butter Brook, Will's Hole Brook and Conant Brook and the Fort Pond Brook system including the incoming streams Guggins Brook, Inch Brook, Grassy Pond Brook, Pratt's Brook and Coles Brook. Both stream systems empty into the Assabet River, which passes briefly through the town at its southern corner. Nagog Pond in the north, forms Acton's border with the Town of Littleton and provides drinking water to the Town of Concord. A small artificial pond is at NARA Park in North Acton.
