Question: Where is Kennebec river located?

Context paragraphs:
Moose River (Maine): The Moose River is an 83 mi river in Maine.  Its source ( ) is in Beattie (Maine Township 2, Range 8, WBKP), on the Canada–United States border, which runs along the height of land between the watersheds of the Kennebec River in Maine and the Chaudière River in Quebec.  From there, the river runs east through Attean Pond and Wood Pond, past the town of Moose River, then through Long Pond and Brassua Lake.  The Moose River empties into Moosehead Lake, the source of the Kennebec River, in Rockwood Strip (T1, R1, WBKP).  The International Railway of Maine was built along Moose River in 1889.

Dead River (New Hampshire): The Dead River is a 3.5 mi river located entirely within the city limits of Berlin, New Hampshire, in the United States.  It is a tributary of the Androscoggin River, which flows south from Berlin before turning east at Gorham and into Maine, eventually joining the Kennebec River at Merrymeeting Bay.  The Abenaki Indians called the Dead River "Plumpetoosuc", which means "shallow, narrow river".

Acadia: Acadia (French: "Acadie" ) was a colony of New France in northeastern North America that included parts of eastern Quebec, the Maritime provinces, and modern-day Maine to the Kennebec River.  During much of the 17th and early 18th centuries, Norridgewock on the Kennebec River and Castine at the end of the Penobscot River were the southernmost settlements of Acadia.  The actual specification by the French government for the territory refers to lands bordering the Atlantic coast, roughly between the 40th and 46th parallels.  Later, the territory was divided into the British colonies that became Canadian provinces and American states.  The population of Acadia included members of the Wabanaki Confederacy and descendants of emigrants from France (i.e., Acadians).  The two communities intermarried, which resulted in a significant portion of the population of Acadia being Métis.

Kennebec River: The Kennebec River is a 170 mi river entirely within the U.S. state of Maine.

Carrabassett River: The Carrabassett River, a tributary of the Kennebec River, is located in Franklin County and Somerset County, Maine, in the United States.  It rises near Sugarloaf Mountain, east of Rangeley Lake, and runs for 33.8 mi , flowing southeast past Kingfield and joining the Kennebec River in the town of Anson.

Two Cent Bridge: The Ticonic Footbridge, popularly known as the Two Cent Bridge, is a suspension bridge that spans the Kennebec River between the city of Waterville and the town of Winslow in Kennebec County, Maine.  It is one of the oldest surviving wire-cable steel suspension bridges and also is considered to be the last known extant toll footbridge in the United States.

Doubling Point Range Lights: The Doubling Point Range Lights are a pair of range lights on the Kennebec River, in Arrowsic, Maine.  Built in 1898 as part of a major improvement on navigational aids on the river, they are the only surviving pair of range lights in the state.  They were listed on the National Register of Historic Places as Kennebec River Light Station on January 21, 1988.

Memorial Bridge (Augusta, Maine): The Memorial Bridge, also known as the Kennebec Memorial Bridge or Kennebec River Bridge, is a bridge in Augusta, Maine, that crosses the Kennebec River, joining the east and west sides of the city.  It carries U.S. Route 201, U.S. Route 202, Route 11, and Route 100.  The bridge is approximately 2,100 feet (640 m) long and has two lanes for traffic and a barrier-protected sidewalk for pedestrians on each side of the roadway.  It was first completed in 1949.

Maine Kennebec Bridge: The Maine Kennebec Bridge is a bridge that crosses the Kennebec River between Richmond and Dresden, Maine.  It was built in 2014 to replace the 84-year-old Richmond-Dresden Bridge, a swing bridge that had previously acted as the only method of crossing the river.  The Maine Kennebec Bridge is significantly taller than the old bridge, and was designed for at least 75 feet (22.86 meters) of clearance during high tide, allowing boats to pass without the need for a swing-span design.

Rockland Branch: The Rockland Branch is a railroad from Brunswick, Maine to Rockland, Maine.  A charter was granted in 1849 to build a railway from the Portland and Kennebec Railroad on the west side of the Kennebec River to Rockland.  Construction through the rocky headlands of the Atlantic coast proved more expensive than anticipated.  The Knox and Lincoln Railroad commenced service to Rockland in 1871 using a ferry to cross the Kennebec River between Bath and Woolwich.  The Knox and Lincoln was leased by Maine Central Railroad in 1891, and became Maine Central's Rockland Branch in 1901.  Maine Central purchased the Samoset destination hotel in nearby Glen Cove (a part of neighbouring Rockport) in 1912, and offered direct passenger service for summer visitors from the large eastern cities.  Carlton bridge was completed in 1927 to carry the railroad and U.S. Route 1 over the Kennebec River.  Maine Central sold the Samoset hotel in 1941, and the last Maine Central passenger train to Rockland was on 4 April 1959.  The State of Maine purchased the branch in 1987 to prevent abandonment.  The line has subsequently been operated by the Maine Coast Railroad, the Maine Eastern Railroad, and, beginning in 2016, the Central Maine and Quebec Railway.
