Question: What two states does the Androscoggin River and Akers pond touch?

Context paragraphs:
Little Androscoggin River: The Little Androscoggin River is a 51.4 mi river in Maine.  It flows from Bryant Pond in Woodstock ( ) to its confluence with the Androscoggin River in Auburn.  The Androscoggin flows into Merrymeeting Bay in the Kennebec River estuary.

Quasi alliance: Quasi alliance is a relationship between two states that have not formed an alliance despite sharing a common ally.  These two states may remain unallied due to alliance hindrances such as historical animosity but still share a common, powerful ally capable of diminishing the two states' security fears due to a common threat.  Japan-Korea relations may be referred to as a quasi alliance as the two states remain unallied, but share a common threat, North Korea, and a common ally, the United States.  The two states remain unallied mainly due to historical animosity rooting from the period of Japanese colonialism.

Sanborn River: The Sanborn River is a 5.8 mi river in Maine.  It flows from its source ( ) on Round Mountain in the unorganized territory of South Oxford to Hicks Pond in the town of Greenwood.  Hicks Pond drains via Niles Brook into the Little Androscoggin River, the Androscoggin River, and thence into Merrymeeting Bay in the Kennebec River estuary.

Akers Pond: Akers Pond is a 276 acre water body located in Coos County in northern New Hampshire, United States, in the town of Errol.  Water from Akers Pond flows via Clear Stream to the Androscoggin River and thence into Maine.

Dead River (Sabattus River): The Dead River is a 10.3 mi tributary of Sabattus Pond in the U.S. state of Maine.  Via the Sabattus River, the outflow of the pond, the Dead River is part of the Androscoggin River watershed, flowing to the Kennebec River and ultimately the Atlantic Ocean.

Sabattus River: The Sabattus River is an 11.4 mi tributary of the Androscoggin River in Maine.  It rises at the outlet of Sabattus Pond in the town of Sabattus and flows south into the town of Lisbon, reaching the Androscoggin just southeast of Lisbon Center and about 1.5 mi upstream (northwest) of Lisbon Falls.  Via the Androscoggin River, water from the Sabattus River flows to the Kennebec River at Merrymeeting Bay and ultimately to the Atlantic Ocean.

Dead River (Androscoggin River): The Dead River is a tributary of the Androscoggin River in western Maine in the United States.  The river flows from Androscoggin Lake, northwest through the town of Leeds 7 mi to the Androscoggin.  This sluggish river is the outlet of a chain of ponds, of which Androscoggin Pond is the largest and last.  The river has the rare power of running either way at different times.  Upon a sudden rise of the Androscoggin River, the flow sets back the current of Dead River into the pond.  It sometimes flows into the pond for three or four days.

Androscoggin River: The Androscoggin River is a river in the U.S. states of Maine and New Hampshire, in northern New England.  It is 178 mi long and joins the Kennebec River at Merrymeeting Bay in Maine before its water empties into the Gulf of Maine on the Atlantic Ocean.  Its drainage basin is 3530 sqmi in area.  The name "Androscoggin" comes from the Eastern Abenaki term "/aləssíkɑntəkw/" or "/alsíkɑntəkw/", meaning "river of cliff rock shelters" (literally "thus-deep-dwelling-river"); or perhaps from Penobscot "/aləsstkɑtəkʷ/", meaning "river of rock shelters".  The Anglicization of the Abenaki term is likely an analogical contamination with the colonial governor Edmund Andros.

Lewiston–Auburn: Lewiston–Auburn (L–A) are twin cities in Androscoggin County, Maine, USA.  Together, they have a population of 59,647 in a combined 101 sqmi .  The cities are commonly called "Cities of the Androscoggin," as they are seated along the banks of the Androscoggin River which separates them.  They share infrastructure and transportation, such as the Lewiston-Auburn CityLink, the Lewiston and Auburn Railroad Company and the Auburn/Lewiston Municipal Airport.  They also form the Lewiston-Auburn Metropolitan Statistical Area, which encompasses Androscoggin County.  The Lewiston–Auburn Economic Growth Council has been promoting the cities as one community for decades in its campaign to promote growth in industry and business.

Richardson Lakes (Maine): Upper Richardson Lake and Lower Richardson Lake are impounded as a single reservoir by Middle Dam at the outlet to Rapid River on the western shore of the lower lake.  Rapid River flows 5 mi to Umbagog Lake headwaters of the Androscoggin River.  Upper Richardson Lake is in the western portion of Richardsontown township, and the lower lake is on the border of Magalloway Plantation and Maine township C. Primary inflow is discharge over Upper Dam on Mooselookmeguntic Lake on the eastern shore of the upper lake.  Smaller tributaries entering the north end of the upper lake include Mill Brook draining the Richardson Ponds, Fish Brook draining Fish Pond, and Beaver Brook draining Beaver Pond, Little Beaver Pond, and Aziscohos Pond.  Other small tributaries include Rand Brook on the western shore, and Mosquito Brook, Metallak Brook, and Bailey Brook on the eastern shore.  The lake offers excellent habitat for adult trout, but with dams on the outlet and major inlet, fish populations are limited by the insufficient spawning and nursery areas of these small tributaries.  The public boat launch area at the north end of the upper lake is 1 mi off Maine State Route 16; and the boat launch area at the south end of the lower lake is accessed by driving 12 mi north of Andover on South Arm Road.
