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

full_context: Document 1: Merrymeeting Lake: Merrymeeting Lake is a 1233 acre water body located in Strafford County in eastern New Hampshire, United States, in the town of New Durham. Its outlet is the Merrymeeting River, flowing south and then northwest to Lake Winnipesaukee.
Document 2: Horn Pond: Horn Pond is a 227 acre water body located on the border of Acton, Maine, and Wakefield, New Hampshire, in the United States. The lake is both spring-fed and fed by the outflows of Great East Lake to the north and Wilson Lake to the east. Horn Pond's outlet is the Salmon Falls River which forms a natural border between Maine and New Hampshire and empties into the Piscataqua River east of Dover, New Hampshire, and ultimately the Gulf of Maine.
Document 3: 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.
Document 4: 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.
Document 5: Saco River: The Saco River is a river in northeastern New Hampshire and southwestern Maine in the United States. It drains a rural area of 1703 sqmi of forests and farmlands west and southwest of Portland, emptying into the Atlantic Ocean at Saco Bay, 136 mi from its source. It supplies drinking water to roughly 250,000 people in thirty-five towns; and historically provided transportation and water power encouraging development of the cities of Biddeford and Saco and the towns of Fryeburg and Hiram. The name "Saco" comes from the Eastern Abenaki word "[sɑkohki]", meaning "land where the river comes out". "The Jesuit Relations", ethnographic documents from the 17th century, refer to the river as "Chouacoet".
Document 6: Cockermouth River: The Cockermouth River is a 9.5 mi stream located in central New Hampshire in the United States. It is the longest tributary of Newfound Lake, part of the Pemigewasset River and ultimately Merrimack River watersheds. The river takes its name from the "Cockermouth Grant", an early name for a portion of the town of Hebron.
Document 7: Third East Branch Magalloway River: The Third East Branch Magalloway River is a 4.0 mi stream in northwestern Maine. It is a tributary of the West Branch Magalloway River, which flows to the Magalloway River, then the Androscoggin River, and ultimately to the tidal Kennebec River and the Atlantic Ocean.
Document 8: 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.
Document 9: Saint John River (Bay of Fundy): The Saint John River (French: "Fleuve Saint-Jean" ; Maliseet: "Wolastoq"( )) is a river, approximately 418 mi long, located principally in the Canadian province of New Brunswick, but also in and arising from the province of Quebec and the U.S. state of Maine. It forms part of the Canada–United States border in two different places along its length. The river drains an area of approximately 55000 km2 , of which slightly more than half is located in New Brunswick. Along that portion of the Atlantic shoreline of North America that lies between the St. Lawrence River and the Mississippi River, the Saint John River is the second longest waterway; only the Susquehanna is longer. It has been nicknamed the "Rhine of North America" for its scenery. The river is regulated by hydro power dams located at Mactaquac, Beechwood, and Grand Falls, New Brunswick.
Document 10: 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.
Document 11: Crystal Lake (Gilmanton, New Hampshire): Crystal Lake is a 455 acre water body located in Belknap County in the Lakes Region of central New Hampshire, United States, in the town of Gilmanton. Crystal Lake is at the head of the Suncook River watershed. Water flows into Crystal Lake from the Belknap Range through Manning and Sunset lakes to the north. Water from Manning Lake enters Crystal Lake via Nelson Brook. Other waterways flowing into Crystal Lake include Wasson Brook and Mill Brook. Water flows out of a dam from the southern end of Crystal Lake via the Suncook Lakes and Suncook River to the Merrimack River. Shoreline development along Crystal Lake consists primarily of summer cottages, with a few year-round residents. Belknap Mountain and Mount Major can be seen from the shoreline.
Document 12: 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.
Document 13: Magalloway River: The Magalloway River is a river in northwestern Maine and northern New Hampshire in the United States. It is a tributary of the Androscoggin River, which flows to the Kennebec River at Merrymeeting Bay in Maine, near the Atlantic Ocean. The total length of the river is 30 mi , or 48 mi if the distances across intervening lakes are included.
Document 14: Umbagog Lake: Umbagog Lake is a wilderness lake located in Coös County, New Hampshire, and Oxford County, Maine. It is one of the most pristine lakes in the state of New Hampshire. It lies in the towns of Errol, New Hampshire, and Upton, Maine, as well as the townships of Cambridge, New Hampshire, and Magalloway Plantation, Maine. The name "Umbagog" is properly pronounced with the stress on the second syllable (um-BAY-gog) and is said to come from the Abenaki word for "shallow water".
Document 15: Mendum's Pond: Mendums Pond is a 253 acre water body located primarily in Strafford County in eastern New Hampshire, United States, in the town of Barrington. Its extreme southern end dips into the town of Nottingham in Rockingham County. The pond is located on the Little River, a tributary of the Lamprey River and part of the larger Piscataqua River watershed.
