The Charles River is a 80-mile long river in Massachusetts that runs from Hopkinton to Boston and empties into the Atlantic Ocean. It has played an important role in the history of Massachusetts, serving as a source of water for early settlers and as a key transportation route for trade. Today, it is also used for recreation, with parks and walking trails lining its banks. The river is managed by the Massachusetts Department of Conservation and Recreation, which operates several dams and reservoirs along the river, including the Wachusett Reservoir and the Quabbin Reservoir. These reservoirs provide drinking water for Boston and surrounding communities. The river also supports agricultural activities such as cranberry farming, and is home to a variety of fish and wildlife species.
