The Charles River is an 80-mile (about 129 km) river in eastern Massachusetts that flows through or alongside many municipalities, including Boston and Cambridge. The lower portion between Watertown Dam and Boston Harbor is heavily developed for recreation, with boating, walking and cycling paths, and parkland along its banks. The river has undergone restoration efforts to improve water quality and ecological health in recent decades. Its presence is central to the urban landscape and symbolism of the Boston region.
